The indoor shelter temperature sensor is used to monitor the

shelter ambient temperature. Various configurable temperature setpoints are used to perform the follow ing functions: » High temperature alarm

» Very high temperature alarm » DG start command during battery discharge cycle » Shelter air conditioner and free cooling ventilation system

control

The battery temperature sensor is used to monitor the battery bank or battery cabinet ambient temperature. The monitored battery temperatures are used to perform the follow ing

functions: » Battery cabinet forced cooling ventilation system control » Battery charge temperature compensation

The AC1-4 temperature sensors are used to monitor the air conditioner vent temperature of each air conditioner unit respectively. The monitored vent temperatures are used to

perform the follow ing functions: » Measure cooling capacity of active air conditioner unit » Indicate a cooling fault based upon pre-defined

operational period, versus measured temperature.

(Blue/White and Orange leads used – measure +/- 4.7ohms

betw een leads, when tested) Typical Sensor Location: Shelter Temperature Sensor

» The shelter temperature sensor is placed in the shelter roof, tow ards the door. Ensure the sensor is not located near any heat or cooling generating sources, such as

shelter lights or air condition vents. Battery Temperature Sensor » The battery temperature sensor is placed betw een the

battery cells, center of the total battery bank. Air Conditioner Vent Temperature Sensor » The air conditioner vent temperature sensor is placed in

the air conditioner vent section (portion w here the cold air blow s out). Ensure it is adequately secured.

Installation Steps:


» Connect Shelter temperature sensor to the SAM2 RMS03

cable termination unit T4 (blue/white) and GD (orange) connection of “Temp Probes” screw terminal connection.

» Connect Battery temperature sensor to the SAM2 RMS03 cable termination unit BT (blue/white) and GD (orange) connection of “Temp Probes” screw terminal connection.

(Input T4 is used for either shelter temperature sensor or AC4 vent temperature sensor. Should 4x aircon vent temperature sensors be required, the shelter reference

temperature w ill have to be monitored by using a humidity/temperature sensor – refer to section 9)

Note:

» Should the shelter temperature sensor not be functional, due to a faulty cable or sensor, the SAM2 RMS03 system w ill indicate a Temperature Probe alarm. (only applicable to shelter temperature sensor)

» A temperature reading of –12C or more refers to a disconnected temperature sensor lead

» A temperature reading of +110C or more, refers to a short circuit sensor lead

10. SAM2 RMS03 – Shelter Humidity/ Temperature Sensor Optionally the Shelter temperature sensor could be replaced w ith a combination Humidity and Temperature sensor (RTH).

Typical Sensor Location: Shelter RTH Sensor » The shelter RTH sensor is normally placed in the shelter

roof, tow ards the door. Ensure the sensor is not located

near any heat or cooling generating sources, such as shelter lights or air condition vents.

Installation Steps:

» Connect Shelter RTH sensor to the SAM2 RMS03 cable termination unit HP (orange) and GD (blue) connection of “Temp Probes” screw terminal connection.

» Ensure that the cable w ith the side marked “Humidity

Sensor” is plugged into the RJ9 socket of the RTH sensor (located inside the sensor).

Note:

» Should the RTH sensor not be functional, due to a faulty cable or sensor, the SAM2 RMS03 system w ill indicate a Humidity Sensor alarm.

» During a humidity sensor failure, as mentioned above, the SAM2 RMS03 assumes a high temperature condition (failsafe), in order to start the generator to ensure the air conditioners are activated.

One of the main purposes of the shelter temperature sensor or RTH (humidity/temperature) sensor combination, is to monitor the shelter temperature threshold at w hich to send a generator

start command (in order to activate the air conditioners), should the configured regulate temperature threshold be exceeded. The default temperature at w hich the generator

start command is activated, is 35C. (user configurable)

11. SAM2 RMS03 – Air Conditioner Control Switch The purpose of the Air Conditioner Control Sw itch (ACS) is to

intelligently control the operation of the air conditioner units in conjunction w ith the SAM2 RMS03 controller unit.

The ACS w ould intelligently control the activation and de-

activation of single or multiple air conditioner units, based upon the monitored shelter temperatures. (up to four air conditioner units could be controlled)

Should the mains supply voltage drop below a pre-defined threshold (220Vac-15% = 187Vac), the ACS w ould cut the mains supply voltage to the air conditioners as a protective measure, w ith an associated alarm indication.

The Air Conditioner Control Sw itch could be used to drive any of the follow ing air conditioning types:

» Single phase (1-port) unit for driving a single air conditioning unit up to 24 000 BTU

» Single phase (2-port) unit for driving 2 independent air conditioning units up to 24 000 BTU

» Single phase (3-port) unit for driving 3 independent air conditioning units up to 24 000 BTU

» Three phase (2-port) unit for driving up to 2 independent air conditioning units of up to 50 000 BTU

» (bigger sw itching capacity rated ACS units available subject to sw itching contactors used)


Single Phase (1-port) Unit Electrical Specifications:



Three Phase (2-port) Unit Electrical Specifications:


Installation Steps:

» Ensure the Air Conditioner Control Sw itch (ACS) Cable is

plugged into the Aircon IDC terminal of the SAM2 RMS03 controller and the 8-w ay screw terminal on the Air

Conditioner Control Sw itch.

» The follow ing connections needs to be done on the air

conditioner control sw itch:

A – ACS control cable from SAM2 RMS03 controller. B – Mains Input (Live and Neutral) connection for AC1.

C – Mains Input (Live and Neutral) connection for AC2.

D – Mains Input (Earth) connection for AC1. E – Mains Input (Earth) connection for AC2. F – Mains control output for AC1 via industrial 3-pin socket.

G – Mains control output for AC2 via industrial 3-pin socket. (AC1 is located on the left side and AC2 is located on the right side)

Note: » AC1 is activated by default (failsafe), should the ACS

control cable from the SAM2 RMS03 be unplugged or the

DC supply voltage to the SAM2 RMS03 sw itched off. » A single ACS cable is used to control up to three air

condition units in a normal cyclic or piggy back

application. Cyclic – each air conditioner runs for the pre-defined

configurable time period before swapping to the standby unit. (during a configurable high temperature setting, tw o air conditioners run

simultaneously) Piggy Back – air conditioner one and tw o cycle

according to pre-defined configurable time period how ever air conditioner three runs permanently. (during a configurable high temperature setting, all

three air conditioners run simultaneously)

» A special dual ACS t-cable is used to control up to four air condition units making use of tw o Air Conditioner Control Sw itch units in a normal cyclic or co-location application. Cyclic – each air conditioner runs for the pre-defined

configurable time period before swapping to the

next, alw ays two at a time. (during a configurable high temperature set point, all four air conditioners run simultaneously)

Co-location - The air conditioner units are cycled

based upon a pre-defined configurable time period. AC1 and AC3 runs together and AC2 and AC4 runs together. (during a configurable high temperature

setting, all four air conditioners run simultaneously)


12. SAM2 RMS03 – Reduced Energy Cooling System (REC)

The reduced energy cooling ventilation system (also know n as free cooling ventilation system) is an optional item part of the SAM2 RMS03 system applicable to indoor shelter type sites.

The purpose of the REC ventilation system is threefold: » Reduction in operational costs by reducing total energy

consumption of the indoor shelter sites by up to 85% or

more. » To provide adequate ventilation during hybrid battery

discharge cycles, when the site is pow ered from the standby batteries and the generator and air conditioner

units are sw itched off. » Under extreme conditions w hen the indoor shelter

temperature is abnormally high, to assist w ith the cooling process if the air conditioner units cannot adequately

regulate the shelter temperature. The REC ventilation system operates on the principal of regulating the shelter inside temperature according to a pre-

defined user configurable threshold, relative to the outside ambient temperature. Thus if the regulated temperature is set to 30 degrees for example, provided the outside ambient

temperature is low er than the inside shelter temperature, the ventilation system w ill regulate the shelter temperature using the ventilation fan at variable speeds to control the temperature and not the air conditioner units. Only if the

ventilation fan cannot maintain the regulated inside shelter temperature threshold or if the outside ambient temperature is higher than the inside shelter temperature, w ould the air conditioner units be activated.

The SAM2 RMS03 free cooling ventilation system consists of the follow ing items: (all metal parts made from 304 stainless steel):

» Inlet Louver Assembly » Passive Pre-filter Cartridge » Outlet Louver and DC Fan Assembly

accommodate a 200mm or 250mm ventilation fan and brush less motor. (default 250mm) The fan housing is made of aluminum die-cast rotor w ith metal

impeller, stove-enameled in black. During operation air blow s over the struts with rotational direction being CCW as seen from rotor side.

The fan could be pow ered from either 24Vdc (16-28Vdc) or 48Vdc (36Vdc-57Vdc).

The fan is supplied w ith a 10 meter electrical cord and has the follow ing connections: Brow n = + (positive) Blue = - (negative)

Yellow /Green = Speed Control Black = Taco Out (RPM) Installation Steps:

» Connect the FAN DC supply voltage to the SAM2 RMS03

controller unit. Ensure to use the same supply voltage that w as used to power the SAM2 RMS03, due to earth

13. SAM2 RMS03 – Mains, Phase and

Frequency Sensor The SAM2 RMS03 controller through the cable termination unit

makes use of a sensor type Mains, Phase and Frequency monitoring unit (MPF) to accurately detect any mains or phase related failures. The unit also provides an analogue indication of the mains supply frequency.

The purpose of the MPF sensor is to detect the presence or absence of mains supply from the utility supplier or generator output (mains load supply into the radio base station).

Thus, should the utility provider provide the mains supply source, the MPF monitor w ould detect if mains is present on all phases as w ell as the frequency of the supply.

Should the generator provide the mains supply, the MPF monitor w ould detect whether the generator is providing a mains supply output on all phases as w ell as the frequency of the supply.

The mains/phase indications are used by the SAM2 RMS03 controller to determine if the mains supply (utility or generator)

is pow ering the radio base station, thus confirming ATS contactor operation. The MPF does not distinguish betw een utility or generator supply, but merely if the load supply to the radio base station is

w ithin operational limits. Failure of both the utility supply and/or generator to provide an AC load supply w ould cause the SAM2 RMS03 controller to report the relevant mains and/or phase related alarms. The

mains, phase and frequency alarms are masked for a period of f ive minutes (default) to provide ample time betw een utility and generator contactor switchover before activation of any alarms. (alarm mask period to avoid any unw anted alarms during

generator start/stop sequence) The MPF sensor is mounted in the rectif ier AC distribution

section (after the AVR if f itted), normally located w ithin the BTS shelter. The MPF w ould indicate an active alarm state should the input voltage of any phase drop below 187VAC (220VAC-15%)


MPF Unit Electrical Specif ications:

Installation Steps: Sensor cable pinouts:

» Connect MPF sensor cable to the SAM2 RMS03 cable

termination unit +12v (orange/w hite), MF (blue/w hite), PF (orange) and GD/-12v (blue) connection of “MPF Unit” screw terminal connection. MF refers to Mains/Frequency alarms and PF refers to Phase Fail alarm.

» Ensure that the cable w ith the side marked “MPF Sensor” is plugged into the RJ9 socket of the MPF sensor.

» Wire the mains live supply for phase 1,2 and 3 by looping a connection from the output of the mains supply load

MCB to the MPF phase 1,2 and 3 live inputs (ensure mains supply is monitored after the load MCB in case of tripping)

» Wire the mains neutral by looping a connection from the neutral bar to the neutral input of the MPF sensor.

Note: » Should the mains voltage per phase be above 187Vac,

the red LED corresponding to the input w ill be active (on). » Should the voltage of any phase drop below 187Vac, the

corresponding LED w ould be off and a phase alarm generated.

» All mains, phase and frequency alarms are masked for a period of f ive minutes upon activation of a utility grid

failure alarm. This ensures adequate time for all contactors to switch over between utility and generator load supply (generator starting). Should the batteries be

fully charged at this moment, hybrid battery discharge w ould be activated and all mains, phase and frequency alarms masked for the entire duration of the battery discharge cycle.

» All mains, phase and frequency alarms are instant w hen utility grid supply is present. Thus alarms w ill be activated w hen utility grid supply is present, how ever no mains or phase voltage detected by the MPF sensor.

» During installation testing phase, refer to the SAM2 RMS03 craft terminal software application (SAM2 RMS03 ECT) or LCD display to verify true unmasked alarm status “Diagnostics → View Inputs”

14. SAM2 RMS03 – Utility Grid Sensor The SAM2 RMS03 controller through the cable termination unit and generator controller makes use of an optional AC Mains sensor (ACM) to accurately detect any utility grid failures.

The ACM sensor w ould not be required should the utility grid supply already be monitored by the ATS/AMF and an alarm output provided accordingly or should the site have no utility grid supply.

The ACM w ould indicate an active alarm state should the input voltage of the utility mains supply, per phase, drop below

187VAC (220VAC-15%)

ACM Unit Electrical Specif ications:


The ACM sensor could be used in tw o applications: » To monitor the AC pow er distribution through the ATS, to

ensure correct contactor operation (default). Input one is used to monitor the utility grid relay contactor, input tw o to

monitor the load output contactor and input three the DG relay contactor. The corresponding LED w ould be off, should the input voltage drop below 187Vac and the applicable alarm output activated.

» To monitor each phase of the utility grid supply and provide an alarm output once any phase voltage drops below 187Vac, the corresponding LED w ould be off and a

phase alarm generated for the relevant phase. Installation Steps:

Sensor cable pinouts:

» The ACM sensor is located w ithin the generator or ATS in close proximity w ith the AMF panel.

» Make use of the ACM sensor cable (4-pair open ended to

open ended, 3m, part of w iring cable kit).

Note:

» The ACM sensor is optional and only required on utility grid sites.

15. SAM2 RMS03 – Battery Bank Voltage and Current Monitor The SAM2 RMS03 controller through the cable termination unit makes use of a sensor type 4-20mA Hall Effect current probe (BCP – battery current probe) to measure the battery bank

charge or discharge current during hybrid cycles. The sensor accurately measures the battery load: » Charge current, during utility grid or generator operation » Discharge current, during battery discharge cycle (hybrid

mode) The battery bank voltage is monitored directly by the SAM2

RMS03 controller DC input supply. The battery voltage of the supply feeding the RMS controller is constantly being monitored. For this reason, make sure that the SAM2 RMS03 controller is pow ered directly from the

battery bank supply (priority feed), using a suitable 10A circuit breaker.


Battery Current Probe (BCP) This sensor makes use of hall-technology, in order to measure dc currents with reference to battery charge or discharge currents.

This measurement technique makes it possible to measure current w ithout any electrical connections to the conductor being measured. The unit simply clamps onto the terminal to be monitored and the installation can therefore be done on live

terminals (no need for disconnection) This measurement probe is unique in the sense that it has a

very w ide dynamic range and the ability to detect current reversal. The current sensor has the ability to auto-range, and can measure charge/discharge currents ranging f rom 1Amp to 200Amp, w ith an accuracy of +/-1% on full range.

Auto ranging is necessary, due to the nominal f loat current on the battery banks that could be as low as 1 Amp, w hile the initial charge or discharge currents could be very high. The sensor is connected to a dedicated 4-20mA analogue

input on the SAM2 RMS03 controller unit. Installation Steps:

Sensor cable pinouts

» Connect the current sensor around the battery bank load conductor (connection between rectifier to battery bank). Ensure to clamp all conductors so the entire battery bank capacity is monitored. Only the positive or negative

conductor must be clamped, not both. » If the negative conductor is clamped, the BCP arrow must

face in the direction aw ay from the batteries tow ards the

load.

» If the positive conductor is clamped, the BCP arrow must

face in the direction tow ards the batteries away from the load. (the norm is alw ays to clamp the current carrying conductor, thus not the station earth potential)

» Make use of the universal alarm cable (2-pair, part of w iring cable kit) to connect the BCP sensor to the SAM2 RMS03 cable termination unit +P (blue), GD (blue/w hite)

and –N (orange) connection of “BCP” screw terminal connector. +P refers to positive DC supply voltage, GD to ground connection and –N to negative DC supply voltage.

» Cut the universal alarm cable to the required length and w ire the BCP sensor screw terminal connections according to the follow ing color scheme: Blue lead of blue/w hite pair – positive.

White lead of blue/w hite pair – ground.

Orange lead of orange/white pair – negative.

» Fault f inding: Ensure to measure approximately 15Vdc between

positive and negative pair. With sensor connected to no load (0A), ensure to

measure approximately 0.603V betw een ground and negative.

With sensor connected to SAM2 RMS03 controller,

but not pow ered, ensure to measure approximately 53ohms betw een ground and negative.

Battery Bank Voltage Measurement

The battery bank supply voltage monitoring capability is an integral part of the SAM2 RMS03 controller unit. The battery voltage feeding the controller is constantly being monitored, w ith the ability of monitoring voltages up to 60Vdc, thus

catering for both +24Vdc and -48Vdc sites. This analogue input is part of the SAM2 RMS03 controller and has the ability to auto-range according to the supply voltage

(18-60Vdc)


Wire the DC supply voltage to pow er the SAM2 RMS03 controller directly from the battery bank “PRIORITY” load output supply via a suitable 10A MCB. Make sure not to use the output from a DC to DC converter, as the monitored

voltage is used to determine the battery bank DoD (depth of discharge) during a hybrid (battery discharge) cycle. Indoor type Unit:

Outdoor type Unit:

Note:

» Ensure that the current sensor alarm is not active once the BCP sensor is connected to ensure proper operation.

» Verify that the BCP indicates a charge current reading during a battery charge cycle and a discharge reading

during a discharge cycle. If the readings are inverted, the direction of the BCP sensor (arrow) needs to be inverted.

» Verify that the battery bank supply voltage is monitored directly from the battery bank. During a discharge cycle

the battery voltage must fall by 1-3Vdc within the f irst minute before stabilizing. If the voltage remains constant during a discharge cycle, the SAM2 RMS03 controller is pow ered from a DC to DC converter supply.

16. SAM2 RMS03 – Hybrid Extension

Module (V00) The standard SAM2 RMS03 controller caters for a single 0-

60Vdc analogue voltage input and a single 4-20mA analogue input used for the BCP sensor. These inputs are used during battery cycling to monitor both battery bank voltage (DoD) as w ell as charge/discharge currents (SoC) of a single battery

bank. In some netw ork deployment scenarios it might be necessary to monitor more than one battery bank (part of multiple tenant applications for example), thus the need for the Hybrid

Extension Module (HEM V00).

The HEM V00 module has tw o possible applications: » Monitoring of tw o independent battery banks at the same

BTS site. In some cases different battery banks are used to pow er the RBS radio equipment (+24Vdc) versus the

transmission equipment (-48Vdc). Both battery banks requires to be monitored in order to measure the battery DoD and SoC levels during hybrid cycling.

» In a shared site application it might be required to monitor

the DC load consumed by the shared operator.

In either of the above scenarios the HEM V00 module is used by connecting it to the SAM2 RMS03 controller through a serial RS485 port. Up to three HEM modules could be connected to the SAM2 RMS03 controller via a common serial

RS485 connection w ith the following added monitoring capabilities on a per module basis: » 1x 4-20mA input – BCP sensor » 1x 0-60Vdc input – Battery bank monitor

» 1x Analogue NTC input – Battery temperature sensor » 4x Digital inputs (spare potential free alarm contacts


Installation Steps: » Connect the second current sensor around the additional

battery bank load conductor to be monitored. Ensure to clamp all conductors so the entire battery bank capacity

is monitored. Only the positive or negative conductor must be clamped, not both.

» If the negative conductor is clamped, the BCP arrow must face in the direction aw ay from the batteries tow ards the

load. (refer to section 13) » If the positive conductor is clamped, the BCP arrow must

face in the direction tow ards the batteries away from the

load. (the norm is alw ays to clamp the current carrying conductor, thus not the station earth potential – refer to section 15)

» Connect HEM V00 BCP sensor cable RJ9 connector to

the dedicated socket on the HEM V00 module labeled “BCP2”.

» Ensure that the cable w ith the side marked “BCP2 Sensor” is w ired to the BCP sensor screw terminal

measure approximately 0.603V betw een ground and negative.

With sensor connected to SAM2 RMS03 controller,

but not pow ered, ensure to measure approximately 53ohms betw een ground and negative.

» Optionally, connect the HEM V00 Battery Temperature

Sensor cable RJ9 connector to the dedicated socket on

the HEM module labeled “Temp”. The battery temperature sensor is normally placed betw een the battery cells, center of total battery block.

Battery Bank Voltage Measurement The additional battery bank supply voltage monitoring is an integral part of the HEM V00 module. The battery voltage

feeding the HEM V00 module is constantly being monitored, w ith the ability of monitoring voltages up to 60Vdc, thus catering for both +24Vdc and -48Vdc battery banks totally isolated from the main battery bank monitored by the SAM2

RMS03 controller. Wire the DC supply voltage to pow er the HEM V00 module directly from the battery bank “PRIORITY” load output supply

via a suitable 1A MCB. Make sure not to use the output from a DC to DC converter, as the monitored voltage is used to determine the battery bank DoD (depth of discharge) during hybrid (battery discharge) cycling.

If required, connect any potential free alarm contacts to be monitored to input 1-4 on the HEM module. (ensure to use the correct polarity as indicated)

» Connect the HEM V00 module to the SAM2 RMS03 cable

termination unit +P (blue), GD (blue/w hite) and –N (orange) connection of “HEM” screw terminal connector.

+P refers to positive DC supply voltage, GD to ground connection and –N to negative DC supply voltage.

Note:

» Before pow ering the HEM V00 module ensure that all w iring connections have been completed (serial connection to SAM2 RMS03 controller, BCP

sensor, Battery bank supply voltage, optional Battery Temp sensor and optional potential free alarm inputs)

» Once pow ered, the HEM V00 pow er/communications LED should f lash slow ly at 3 second intervals, indicating

correct powering sequence. » Once the HEM V00 module address has been set

successfully using the SAM2 RMS03 ECT terminal software program, the pow er/communications LED w ill

f lash faster at 1 second intervals, indicating active communications w ith the SAM2 RMS03 controller.

» Once communications are established w ith the SAM2 RMS03 controller, use the ECT terminal software to verify

that the BCP indicates a charge current reading during a battery charge cycle and a discharge reading during a discharge cycle, battery temperature sensor indicates a

17. SAM2 RMS03 – Hybrid Extension Module (V01)

The standard SAM2 RMS03 controller caters for a single 0-60Vdc analogue voltage input and a single 4-20mA analogue input used for the BCP sensor. These inputs are used during battery cycling to monitor both battery bank voltage (DoD) as

w ell as charge/discharge currents (SoC) of a single battery bank. In some netw ork deployment scenarios it might be necessary

to monitor the load current to multiple tenant sites (DC load consumed by shared operator), thus the need for the Hybrid Extension Module (HEM V01).

The HEM V01 module is used by connecting it to the SAM2

order to f it the relevant current sensors. Ensure to clamp all conductors so the entire load supply to the particular tenant is being monitored. Only the positive or negative conductor must be clamped, not both.

» If the negative conductor is clamped, the BCP arrow must face in the direction from the load (direction of battery).

» If the positive conductor is clamped, the BCP arrow must

face in the direction to the load. (the norm is alw ays to clamp the current carrying conductor, thus not the station earth potential.

18. SAM2 RMS03 – Navigation Light Sensor – AC Mains Type The SAM2 RMS03 makes use of a sensor type Navigation Light monitoring (AWM) unit to accurately detect any failure of one or more tow er lamps. The SAM2 RMS03 system has tw o

types of navigation light sensors, one for AC type navigation lights and one for DC type navigation lights. The installation procedure for both is practically the same. (ensure how ever that the correct type is used for the applicable site application)

The AWM AC mains type sensor is located w ithin the AC distribution box and w ired in series with the live supply (output of NAV light MCB) of the navigation tow er lights and calibrated according to the amount of current draw n by the lamps. Any

deviation in the current drawn will cause an active alarm. Due to the AWM sensor being calibrated on a per site basis, virtually any amount or type of lamps could effectively be

monitored by the unit. AWM AC-type Unit Electrical Specif ications:

Installation Steps:


» Connect optional AWM sensor cable (RJ9 (4x4) to open ended – 12m) to the SAM2 RMS03 cable termination unit 12V (orange/white), NL (orange), SL (optional) and GD (blue) connection of “AWM Unit” screw terminal

connection. NL refers to Navigation Light alarm and SL refers to optional Security Light alarm.

» Ensure that the cable w ith the side marked “AWM Sensor” is plugged into the RJ9 socket of the AWM

sensor.


» Wire the mains live supply from the navigation light MCB output to the AWM sensor input as follow s: IN1 Input – if total pow er drawn by tower lamps less

than 20W. IN2 Input – if total pow er drawn by tower lamps less

than 40W.

IN3 Input – if total pow er drawn by tower lamps less

than 60W. » Wire the output, OUT, of the AWM sensor to the mains

supply cable feeding the tow er lamps.

» In order to calibrate the AWM sensor, the follow ing procedure has to be follow ed: (note – repeat this procedure upon any lamp change)

Connect the AWM sensor as indicated in the

diagram above. Sw itch on the AWM MCB and ensure all tow er

lamps are functional. Using a small screw driver, adjust the “sensitivity”

screw on the AWM sensor fully clockwise, thus

maximum sensitivity. Both AWM LED’s must be on (“Lights On” and “Calibrate”).

Turn the “sensitivity” screw slowly in an anti-

clockw ise direction, thus decreasing sensitivity, until the red “Calibrate” LED goes off. Only the green

“Lights On” LED must now be on. For the best performance, the sensitivity setting

should be as close as possible to the point w here the red “Calibrate” LED is constantly on. It is normal

for the “Calibrate” LED to f lash every now and then. If the “Calibrate” LED is constantly on, it means the sensitivity has been set to high (out of calibration) or the mains supply voltage is momentarily too

high/low , resulting in in/decreased current f low. Verify correct operation by turning off the power to

the tow er lamps. Both LED’s must now be of f and the SAM2 RMS03 unit should indicate an alarm condition. (note that the navigation lights alarm is

masked in daylight hours and must be view ed in the unmasked state using the SAM2 RMS03 LCD display or technician craft terminal software application)

Turn on the pow er to the tow er lamps and verify that

the AWM green LED “Lights On” is burning. The SAM2 RMS03 should indicate no alarm condition.

To achieve maximum range w ith the sensitivity

screw, ensure to w ire the input corresponding to the total current drawn by the lamps.

Note: » Ensure that all the lamps are sw itched on and functional

before calibrating the AWM sensor. » Ensure to re-calibrate the AWM sensor upon lamp

replacements. » AWM alarm indication is masked during daytime

operation to compensate for daylight sensors. (from 4am to 8pm).

» During installation testing phase, refer to the SAM2 RMS03 craft terminal software application (SAM2 RMS03

ECT) or LCD display to verify true unmasked alarm status “Diagnostics → View Inputs”

19. SAM2 RMS03 – Navigation Light Sensor – DC Supply Type

The SAM2 RMS03 makes use of a sensor type Navigation Light monitoring (AWM) unit to accurately detect any failure of one or more tow er lamps. The SAM2 RMS03 system has tw o types of navigation light monitors, one for AC type navigation

lights and one for DC type navigation lights. The installation procedure for both are the same. (ensure how ever that the correct type is used for the applicable site application)

The DC type AWM sensor is located in the DC distribution box and w ired in series w ith the DC supply (output of NAV light MCB) of the navigation tow er lights and calibrated according to

the amount of current draw n by the lamps. Any deviation in the current drawn will cause an active alarm. Due to the AWM sensor being calibrated on a per site basis,

virtually any amount of lamps could effectively be monitored by the unit. AWM DC-type Unit Electrical Specif ications:

Installation Steps:


» Connect optional AWM sensor cable (RJ9 (4x4) to open

» Ensure that the cable w ith the side marked “AWM Sensor” is plugged into the RJ9 socket of the AWM DC sensor.

» Wire the negative DC supply from the navigation light

MCB output to the AWM DC input “IN”. » Wire the output “OUT” of the AWM DC to the supply

cable feeding the tow er lamps (DC supply).

» In order to calibrate the DC type AWM sensor, the

follow ing procedure has to be follow ed: (note – repeat this procedure upon any lamp change)

Connect the AWM DC sensor as indicated in the

diagram above. Sw itch on the AWM MCB and ensure all tow er

lamps are functional.

Using a small screw driver, adjust the “sensitivity”

screw on the AWM DC sensor fully clockwise, thus maximum sensitivity. Both AWM LED’s must be on (“Lights On” and “Calibrate”).

“Diagnostics → View Inputs”

20. SAM2 RMS03 – Utility Grid Management

The SAM2 RMS03 controller through the cable termination unit and generator controller makes use of an optional 3-phase utility grid check meter for the purpose of monitoring the utility grid supply in terms of voltage, current and Kw H consumption.

(on a per phase basis) The SAM2 RMS03 communicates w ith the utility grid meter, using a serial RS485 connection.

The utility grid meter is deployed as a check meter w ith the follow ing features: » Statistical Kw H counters – based upon actual load

consumption and/or total load consumption over a 24 hour period.

» Statistical voltage per phase indication. » Statistical load current per phase indication.

» Optional, manual or automated load disconnect function. (in conjunction w ith meter control relay – U1) The SAM2 RMS03 controller has the ability to disconnect the utility AC load and run the generator or battery

backup, should the grid pow er prove to be unstable. The grid pow er is constantly monitored in terms of

the configured mains fail stability criteria period (one minute default). If the mains voltage drops below the configured voltage threshold, on any of the phases,

the utility grid load w ill be disconnected and the generator started or battery discharge cycle started, in order to carry the load.

Should the mains voltage regain stability based

upon the configured voltage and stability duration (f ive minutes default), on all three phases, the utility grid load supply w ill be reconnected and the generator stopped or the battery discharge cycle

ended. » Utility grid Hybrid Control. In certain cases it w ould be

beneficial to cycle the site batteries in conjunction w ith the utility grid supply. The SAM2 RMS03 controller could

be configured to disconnect the utility grid supply, once the required battery SOC (state of charge) is reached. The utility grid supply w ould be reconnected once the battery reaches the configured DoD (depth of discharge)

level. (generator control forms part of the above control logic to ensure the generator is started should utility grid failure occur)

Installation Steps:

» Make use of the utility grid meter communications cable

(4-pair, part of w iring cable kit) to connect the utility meter to the SAM2 RMS03 generator controller, P+ (blue), N-

(blue/w hite) and GD (orange) connection of “SAM2 RS485” screw terminal connection. P+ refers to RS485 Positive, N- refers to RS485 Negative and GD to supply Ground connection.

» Terminate the other end of the utility grid meter communications cable to the RJ12 6-pin connector provided as follow s:

Orange – Ground – Pin1


Blue – Positive RS485 – Pin2

Blue/White – Negative RS485 – Pin3

» Ensure to plug the cable into the RJ12 “communications interface” socket of the utility grid meter. (left communications socket as indicated below )

» Connect the utility meter phases as follow s:

Phase 1 (Red) In – Terminal L1 IN

Phase 1 (Red) Out – Terminal L1 OUT

Phase 2 (Blue) In – Terminal L2 IN

Phase 2 (Blue) Out – Terminal L2 OUT

Phase 3 (Yellow ) In – Terminal L3 IN

Phase 3 (Yellow ) Out – Terminal L3 OUT

Neutral (Black) In – Terminal N IN

Neutral (Black) Out – Terminal N OUT

» The utility meter is normally connected to the mains 3-phase input supply directly from the utility grid supplier.

Optionally, in some cases the utility meter is connected to the 3-phase load supply from the ATS. In this case the utility meter is capable of measuring both the utility grid and generator 3-phase supply. (data is stored in tw o

separate registers for utility versus generator AC mains statistics)

» The utility meter is not w eather proof and needs to be placed in the optional outdoor enclosure should inadequate space be available indoors during installations.

Note: » Ensure all utility grid phases are connected as illustrated

above. Ensure to measure the desired 230Vac per phase on terminals (L1, L2, L3 – IN, w ith reference to N – IN)

» If meter connection is through to the load, ensure to measure the same voltage on terminals (L1, L2, L3 – OUT, w ith reference to N - OUT)

» Ensure the meter Kw H indicator is pulsing (1-2 second intervals) indicating presence of utility mains pow er.

» Use the SAM2 RMS03 LCD display or technician terminal software program to verify operation of the meter. (meter

communications alarm should be clear and voltage/current per phase reading visible)

21. SAM2 RMS03 – Equipment Mains Monitoring Unit The utility grid meter is used to monitor and verify the utility AC mains grid and/or generator supply to site. In some netw ork deployment scenarios it might be necessary

to monitor the distributed AC load current to multiple tenant sites (AC load consumed by shared operator), thus the need for the Equipment Mains Monitoring Unit (EMU).

The EMU module is used by connecting it to the SAM2 RMS03 controller through a serial RS485 port. Up to three EMU modules could be connected to the SAM2 RMS03 controller

via a common serial RS485 connection w ith the follow ing added monitoring capabilities on a per module basis: » 6x voltage inputs – Current Transformer (CT’s) (up to tw o

3-phase tenants or up to six single phase tenants).

» 1x 3-phase AC Mains supply input – Tenant distributed mains supply voltage.

» 1x Alarm output – AC Mains low voltage alarm.

Installation Steps: » Connect the tenant current transformers around the

particular AC load supply to be monitored (either Single

Phase load supply or 3-Phase Load supply). The AC load supply to the applicable tenant w ill need to be disconnected in order to f it the relevant current sensors. Ensure to clamp all conductors so the entire load supply

to the particular tenant is being monitored. (the current transformers are not directional, thus could be f itted in any direction)

» The current transformers are normally located w ithin the

AC distribution box, after the MCB feeding the particular tenant.

» The current transformers are factory terminated on a 650mm w iring harness (CT1-3, cable harness 1 and CT4-

6, cable harness 2). Make sure to connect the correct cable harness to the appropriate EMU monitoring input.

» The tenants AC Mains 3-Phase supply voltage monitoring is an integral part of the EMU module. The AC mains supply voltage feeding the EMU module is constantly being monitored, w ith the ability of monitoring voltages up

to 260Vac


» A low voltage alarm output (default 187vac) could optionally be w ired to any of the SAM2 RMS03 controller spare inputs. The alarm threshold is configurable using the SAM2 RMS03 craft terminal software application

(SAM2 RMS03 ECT) and is activated if any one of the monitored phases drops below this setpoint.

» Connect the EMU module to the SAM2 RMS03 cable termination unit +P (orange), GD (blue/w hite) and –N (orange/white) connection of “HEM MOD” screw terminal connector. +P refers to positive RS485 communications,

GD to supply ground connection and –N to negative RS485 communications.

Note: » Before pow ering the EMU module ensure that all w iring

connections have been completed (serial connection to SAM2 RMS03 controller, CT

sensors, mains supply voltage)

» Once pow ered, the EMU pow er/communications LED should f lash each time interrogated by the SAM2 RMS03 controller, indicating communications.

» Once communications are established w ith the SAM2

RMS03 controller, use the ECT terminal software to verify that the CT’s indicates a load current reading (on a per tenant basis) and AC mains supply w ithin range.

» Fault f inding: Should no load current values be displayed, refer to

CT sensor cable harness connections. Confirm AC mains voltage on all phases.

If no communications established w ith SAM2

RMS03 controller confirm serial connection cable w ired polarities

22. SAM2 RMS03 – Generator

Controller One of the primary functions of the SAM2 RMS03 controller is

to perform generator remote start/stop control part of hybrid battery cycling. The SAM2 RMS03 controller does not replace the existing site AMF/ATS unit, but w orks in conjunction w ith these units to

perform the follow ing basic functions: » Generator Control:

Automatic start/stop dependent upon the state of the

utility grid ac mains supply. Automatic start/stop part of hybrid battery

charge/discharge cycling.

Remote start/stop part of system test.

Remote Reset upon activated fault condition.

» Alarm Monitoring: Utility Grid AC Mains Fail.

Generator Running (DG started successfully).

Generator Fault (DG generic fault indication).

Generator Start Fail (DG failed to start successfully)

Generator Manual Override (DG remains running

after a DG stop control signal). Generator on Load (DG load contactor activated).

Generator Oil Pressure (DG LLOP fault indication).

Generator Temperature (DG HT fault indication).

Generator Low fuel (optional DG low level fuel

sw itch) Generator Door (optional DG canopy intrusion)

Generator Emergency Stop (optional DG emergency

stop button)

The SAM2 generator controller (DGC) module operates in conjunction w ith the SAM2 RMS03 controller to perform the above mentioned functions.

The DGC consists of the following connections that would be

described in detail w ithin this section of the manual: A – SAM2 RMS03 auxiliary pow er and RS485 communications connection.


B – Fuel sensor auxiliary power and RS485 communications connection. C – Generator monitored alarm inputs. D – Generator 12V battery monitoring inputs.

E – Generator tw o start/stop and reset control. F – Generator one start/stop and reset control. G – Generator start/stop test button.

A – SAM2 RMS03 Auxiliary Power and RS485 Comms: Installation Steps:

» Connect the DG Alarm/control cable SubD9 pin

connector to the SAM2 RMS03 cable termination unit “DG Control” connector.

» Route the open end of the cable to the generator ATS/AMF panel w here the SAM2 generator controller (DGC) w ould be installed.

» Terminate the cable pairs on the DGC “SAM2 RS485”

screw terminal connector as follows:

Note: » The blue and blue/w hite pair is used for RS485 serial

communications betw een the SAM2 RMS03 controller

and DGC controller. » The orange and orange/w hite pair is used for the auxiliary

12Vdc supply to pow er the DGC controller from the SAM2 RMS03 controller.

» The green and green/w hite pair carries the same auxiliary 12Vdc supply as the orange pair and w ould thus be bundled together to ensure a proper stable 12V supply.

» The brow n and brown/white pair carries the same

auxiliary 12Vdc supply as the orange pair and w ould thus be bundled together to ensure a proper stable 12V supply.

B – Fuel Sensor Auxiliary Power and RS485 Comms: Refer to section 24 of this manual – SAM2 RMS03 Fuel Management.

C – Generator Monitored Alarm Inputs: Refer to section 23 of this manual – SAM2 RMS03 Generator Alarm Monitoring.

D – Generator 12V Battery Monitoring Inputs: Installation Steps:

» Use any of the 4-pair alarm cable off -cuts to w ire the DG

12V battery monitoring inputs. » Generator one 12V battery is connected to the DGC

“DG1” screw terminal connector, blue to +12V connection and blue/w hite to GD (ground) connection.

» Generator tw o 12V battery is connected to the DGC

“DG2” screw terminal connector, orange to +12V connection and orange/w hite to GD (ground) connection.

Note:

» The generator 12V battery connection could be tapped from the AMF panel dc supply input, as it is normally pow ered directly from the generator standby battery. (before connecting, ensure that the above input is in fact

the generator 12V battery and not a standby battery) E+F - Generator Start/Stop and Reset Control:

Installation Steps:

Under normal conditions the SAM2 RSM03 controller issues a remote start command once a utility grid AC mains supply failure is detected. How ever at this point tw o conditions are verif ied, that could

influence this sequence: » Batteries fully charged according to the configured SoC,

the DG w ill not be started and a hybrid battery discharge

cycle activated. » If the DG did not run in the last user configurable period

(default 24 hours), the DG w ill be started under test by the SAM2 RMS03 controller for a user configurable

timeframe (default 5 minutes). Should the battery be charged to the required SoC, the DG w ill be stopped and the battery discharge cycle activated. If not, the DG w ill remain running until battery

SoC reached or utility grid mains supply returns. Each DG start sequence is controlled through a single relay w ith dual sw itchover contacts by the SAM2 RMS03 controller

in conjunction w ith the generator controller.


» Make use of the 4-pair DG Alarm/control cable, off-cuts, to connect the DGC generator start/top and reset connections to the generator AMF/ATS.

» In case of single generator control, make the follow ing

connections on the DGC “Start-1” screw terminal connector: DG1 Remote Start NO (normally open relay) contact

- Blue of Blue/w hite pair. DG1 Remote Start NC (normally closed relay)

contact – Blue of Blue/w hite pair.

DG1 Remote Start CM (common) contact – White of

Blue/w hite pair. (before connecting the remote start controlling pair, ensure to determine w hether a NO or NC contact is required and w ire accordingly)

» In case of dual generator control, make the follow ing

connections on the DGC “Start-2” screw terminal connector:

DG2 Remote Start NO (normally open relay) contact

- Green of Green/w hite pair. DG1 Remote Start NC (normally closed relay)

contact – Green of Green/w hite pair. DG1 Remote Start CM (common) contact – White of

Green/w hite pair. (before connecting the remote start controlling pair,

ensure to determine w hether a NO or NC contact is required and w ire accordingly)

Note:

The NC contact (inverted logic) of the SAM2 RMS03 controller is closed (failsafe) upon a DG start command, resulting in de-energizing the dual sw itchover relay located on the generator

controller unit: » Wire the required contact NC (short circuit) or NO (open

circuit) relay contact to the applicable ATS/AMF, remote start input.

» The above contacts are potential free and could be referenced to ground or +12V, based upon the requirements from the ATS/AMF.

The DG reset sequence for both generators are controlled through a single relay w ith dual sw itchover contacts by the SAM2 RMS03 controller in conjunction w ith the generator controller.

» Make use of the 4-pair DG Alarm/control cable, off-cuts, to connect the DGC generator start/top and reset connections to the generator AMF/ATS.

» Tw o relay w iring positions are provided in case of single

or dual generator control, both operating simultaneously. In case of single generator control, make the follow ing connections on the DGC “Reset-1” screw terminal connector:

DG1 Remote Reset NO (normally open relay)

contact - Orange of Orange/w hite pair. DG1 Remote Reset NC (normally closed relay)

contact – Orange of Orange/w hite pair. DG1 Remote Reset CM (common) contact – White

of Orange/w hite pair. » In case of dual generator control, make the follow ing

connections on the DGC “Reset-2” screw terminal connector: DG2 Remote Reset NO (normally open relay)

contact - Brow n of Brown/white pair.

DG2 Remote Reset NC (normally closed relay)

contact – Brow n of Brown/white pair. DG2 Remote Reset CM (common) contact – White

of Brow n/white pair. (before connecting the remote reset controlling pair, ensure to determine w hether a NO or NC contact is

required and w ire accordingly)

Note: The NO contact of the SAM2 RMS03 controller is closed upon

a DG reset command, resulting in energizing the dual sw itchover relay located on the generator controller unit: » Wire the required contact NC (short circuit) or NO (open

circuit) relay contact to the applicable ATS/AMF, remote

reset input. » The above contacts are potential free and could be

referenced to ground or +12V, based upon the

requirements from the ATS/AMF.

» During a DG start command from the SAM2 RMS03 controller ensure the ATS/AMF sends a start pulse to the

DG by cranking the engine. » During a DG reset command from the SAM2 RMS03

controller ensure the ATS/AMF fault condition is cleared. Should the fault condition return, DG maintenance or

repairs w ould be necessary. Generator remote start/reset control sequence The SAM2 RMS03 controller has a specif ic sequence in w hich

a single or dual generator is remotely started, w hich is hardcoded in the f irmw are with limited user configurable settings.

» When the DG needs to be started, due to a utility mains grid failure alarm (A) or due to a low battery threshold (DoD reached), the remote start N/C relay is de-energized. The duration of the remote start contact is

user configurable between 0-255 seconds (default 30 seconds). The DG start pulse is delayed by a user configurable “DG start delay” period (B) betw een 0-255 seconds (default 60 seconds).

» When the DG needs to be stopped, due to utility grid mains being restored (A) or due to hybrid battery discharge activation, the remote start N/C relay is


energized. The sw itchover of the DG start contact is delayed by a user configurable “DG stop delay” period (C) betw een 0-255 seconds (default 60 seconds).

» Should the DG not be started upon the f irst start attempt

the SAM2 RMS03 w ill issue another remote start command. The remote start attempts are f ixed to four (hardcoded in the f irmw are), at w hich a “DG fail to start” (D+E) alarm is activated.

» The pause/reset intervals between the remote start pulses are f ixed to 30 seconds and hardcoded in the f irmw are.

» Once a “DG fail to start” alarm is activated for a particular DG the SAM2 RMS03 controller w ill no longer try and start the DG unless one of the follow ing conditions are met:

Whenever any of the hybrid suspend conditions

changes state. Alarms conditions such as shelter temperature for example.

Whenever hybrid battery discharge is deactivated.

Both DG are off due to the presence of grid utility

mains supply DG remote start command

DG remote reset command

DG sw ap (either manual or auto)

Decreasing BTS battery voltage (every 1volt drop in

threshold)

Note: Once the “DG fail to start” alarm is cleared, the above sequence is repeated.

» A control command executed from the management platform or technicians craft terminal (F), in terms of:

DG remote start command (G)

DG remote stop command (G)

DG remote reset command (G)

DG remote sw ap command (G),

w ould cause the generator to respond immediately, thus zero delay (H), besides the netw ork SMS/GPRS/Edge message delays.

G - Generator Start/Stop test button: Test Procedure:

» The DGC is equipped w ith a “DG Test” button used to

perform the follow ing tests:

When DG is off – Pressing the button w ill start and

run the DG for the default test duration (5 min). When DG is running – Pressing the button w ill stop

the DG for the default test duration (5 min). (The DG w ill only be stopped if the site batteries are at the required SoC, otherw ise the DG w ill remain running)

23. SAM2 RMS03 – Generator Alarm

Monitoring The SAM2 RMS03 controller in conjunction w ith the generator

controller unit makes provision to monitor eight general purpose (dry contacts) generator alarm indications. (configurable for N/O or N/C alarm state) One DGC could be used to control and monitor single or dual

generators. Should additional alarm inputs be required or the distance betw een the generators do not w arrant a single DGC, tw o DGC units could be installed on the same RS485 communications cable pairs.

Installation Steps:

» Make use of the 4-pair DG Alarm/control cable, off-cuts (tw o pieces), to connect the DGC generator alarm inputs to the generator AMF/ATS and AMC (AC Mains) sensor.

» The default alarm indications for single generator monitoring are as follow s: (user configurable) Alarm 1 (Blue) – Utility AC Mains Fail

Alarm 2 (Orange) – Mains on Load

Alarm 3 (Green) – DG1 on Load

Alarm 4 (Brow n) – DG1 Run

Alarm 5 (Blue) – DG1 Fault

Alarm 6 (Orange) – DG1 High Temperature

Alarm 7 (Green) – DG1 Low Oil Pressure

Alarm 8 (Brow n) – DG1 Door (Intrusion)

» All alarm inputs (1-8) uses the same ground (DG) connection. Ensure to w ire all the common “w hite” leads of all alarm inputs to the “GD” terminal.


Dependent upon the ATS/AMF type, the input alarm signals could be referenced to ground (0V) or +12V. Ensure to move the reference links (IP1-IP8) corresponding to each alarm input accordingly. (link in 0V and link out +12V)

» The default alarm indications for dual generator (using a

Alarm 2 (Orange) – Mains on Load

Alarm 3 (Green) – DG1 on Load

Alarm 4 (Brow n) – DG1 Run

Alarm 5 (Blue) – DG1 Fault

Alarm 6 (Orange) – DG2 on Load

Alarm 7 (Green) – DG2 Run

Alarm 8 (Brow n) – DG2 Fault

» All alarm inputs (1-8) uses the same ground (DG) connection. Ensure to w ire all the common “w hite” leads of all alarm inputs to the “GD” terminal.

Dependent upon the ATS/AMF type, the input alarm signals could be referenced to ground (0V) or +12V. Ensure to move the reference links (IP1-IP8) corresponding to each alarm input

accordingly. (link in 0V and link out +12V) Note: » Meaning of the follow ing visible alarm indications:

o Flashing – DG Run active, DG on Load clear.

LED5 – Hybrid Status (HS)

o On – Hybrid battery discharge active. o Off – Site on AC pow er (charging).

o Flashing – Site Battery discharging but not in hybrid mode.

» The above alarm connections needs to be tested on the SAM2 RMS03 controller by activating each individually as follow s: Utility AC Mains Fail – Fail the utility AC Mains

supply by disconnecting the load MCB.

Mains on Load – Restore the utility AC Mains MCB

and confirm that the mains contactor carries the load supply.

DG on Load – Fail the utility AC Mains supply and

ensure the DG is started. Confirm that the site load is shifted to the DG contactor to carry the load

supply. DG Run – Execute a remote DG start command and

confirm the DG starts successfully. DG Fault – By activating any temperature or oil

pressure alarm before the DG is running. DG High Temperature – Short the temperature

sensor to ground w hile the DG is running.

DG Low Oil Pressure – Short the oil pressure sensor

to ground w hile the DG is running. DG Door (Intrusion) – Open the generator canopy

doors.

24. SAM2 RMS03 – Fuel Management The SAM2 RMS03 controller through the generator controller

makes provision to monitor dual fuel tanks of virtually any shape, size and capacity. The SAM2 RMS03 fuel management option consists of the

follow ing items: » Fuel Sensor » Fuel Tank Lid Sensor » Water in Diesel Sensor

The SAM2 RMS03 controller has the ability to measure the actual amount of diesel stored in the fuel tank and to detect

w hen the fuel tank lid is open. The w ater detection sensor is used to indicate that w ater is present in the diesel tank. Fuel Sensor

The fuel management option consists of an analogue pressure sensor (submersible or externally mount) that is accurately calibrated according to the tank dimension using the SAM2 RMS03 diagnostics and configuration software. The measured

pressure is converted to a fuel level expressed in litres or gallons. Alternatively an ultrasonic sensor could be used if more suitable to the installation environment. The measured time for

a high frequency sound wave echo to reflect from the measured fuel level is converted to a fuel level expressed in litres or gallons.

Communication betw een the SAM2_RMS03 controller and the fuel sensor is through a serial RS485 port. The fuel sensor is pow ered by one of the SAM2 RMS03 controller auxiliary

12Vdc supplies.


Installation Steps: » Should the distance betw een the fuel tank and the

AMF/ATS (w here the DGC is located) be too far, make

use of the Fuel Tank sensor cable (4-pair, part of w iring cable kit), in order to extend the cabling, to connect the fuel probe to the DGC.

» The cable termination box is used to securely join all

cable connections betw een the fuel sensor and fuel tank sensor cabling. The cable termination box is rated IP65 and can be used outdoors.

» Connect the fuel sensor to the DGC as follow s:

P+ terminal (RS485 Positive) to Blue of fuel sensor.

N- terminal (RS495 Negative) to Yellow of fuel

sensor.

12V terminal (Positive supply) to Black of fuel

sensor. GD terminal (Negative supply) to White of fuel

sensor. (pairs are polarity sensitive, thus do not invert).

» When using a submersible pressure sensor, f it the fuel sensor ensuring that it is lying at the bottom of the tank.

» The SAM2 RMS03 controller through the DGC uses a single cable-pair to communicate w ith the fuel sensor via

RS485 and a separate pair for the 12Vdc supply to power the probe.

» The fuel sensor cable has a clear plastic “Breather” pipe at the center of its core, this pipe must not be bent or

sealed as “unobstructed” airf low via this pipe is necessary for correct operation of the sensor. The fuel sensor cable has a screen and a red lead; both

are not used and may be cut.

Note: » During installation each fuel sensor needs to be

calibrated according to tank capacity and volumetric pressure to ensure maximum accuracy. Tank calibration is done using the SAM2 RMS03 serial diagnostics and configuration software – “Fuel Probe Wizard” application.

» Before starting the fuel sensor calibration process, ensure the follow ing: The fuel sensor is communicating w ith the SAM2

RMS03 controller. Should the fuel sensor not communicate w ith the

SAM2 RMS03 controller a “Fuel Probe1 Fail” alarm

w ould be active. (verify wiring connections to clear alarm)

Make sure the DG is not running to ensure minimum

fuel level vibration during the calibration process. Ensure the tank is clean and free of sludge (bottom

residue) and equipped w ith suitable “breather” pipe

in terms of pressure buildup part of daily temperature changes.

Fuel Tank Lid Sensor The optional fuel tank lid kit is a custom made tank lid sw itch and sensor, universal to most types of tanks available.

The sensor kit consists of an active switch and magnetic sensor. The sw itch is mounted w ithin the tank inlet and the magnetic sensor in the tank lid. Once the lid is opened an alarm is

activated and upon closure of the tank the alarm is deactivated. This concept is used to determine w hen the fuel tank is either being f illed or possibly fuel being siphoning.

The SAM2 RMS03 controller takes a fuel reading upon alarm status change, thus fuel added or removed. These fuel readings are used part of the customized fuel management

reports. Installation Steps:

» Should the distance betw een the fuel tank lid kit and the AMF/ATS (w here the DGC is located) be too far, make use of the Fuel Tank sensor cable (4-pair, part of w iring cable kit), in order to extend the cabling, to connect the

fuel tank lid kit to the DGC. » The cable termination box is used to securely join all

cable connections betw een the fuel tank lid kit and fuel tank sensor cabling. The cable termination box is rated

IP65 and can be used outdoors.


» Connect the fuel tank lid sensor to the DGC as follow s:

“DG Alarm Inputs” screw connection, input terminal

8 to Blue of fuel tank lid sensor. (note, any spare alarm input could be used)

12V terminal (Positive supply) to Brow n of fuel tank

lid sensor. GD terminal (Negative supply) to Black of fuel tank

lid sensor. (note, the negative supply also acts as the alarm input ground) (pairs are polarity sensitive, thus do not invert).

» Physically mount the active sw itch (A) to the inlet of the fuel tank. Ensure the beveled edge of the active pickup

faces upwards, with the cable facing dow nwards. » The rotation of the mounting bracket (B) w ould be

determined by the type of thank.

» Mount the magnetic sensor (C) in the center of the tank lid.

Note:

» During installation ensure that the mounting bracket, active sw itch and magnetic sensor are securely and neatly attached to the fuel tank.

» Align the active sw itch and magnetic sensor to ensure the

alarm clears w hen tank lid is closed and alarm activates w hen tank lid is opened.

» The tank lid alarm state could be tested using SAM2 RMS03 serial diagnostic and configuration software or

LCD display. Water in Diesel Sensor

The optional w ater in diesel sensor (submersible or externally mount) is used to detect w ater contamination of the diesel fuel. The sensor is a custom-made liquid level, solid-state device

designed to detect the presence or absence of an electrically conductive liquid. Each sensor contains integral, high-temperature-rated electronics that generate an alternating voltage to the stainless steel tip. The presence of an

electrically conductive liquid completes the circuit w hich, in turn, changes the condition of the transistor output (alarm state).

Installation Steps: » Should the distance betw een the w ater in diesel sensor

and the AMF/ATS (w here the DGC is located) be too far, make use of the Fuel Tank sensor cable (4-pair, part of w iring cable kit), in order to extend the cabling, to connect the w ater in diesel sensor to the DGC.

» The cable termination box is used to securely join all cable connections betw een the water in diesel sensor and fuel tank sensor cabling. The cable termination box is rated IP65 and can be used outdoors.

» Connect the w ater in diesel sensor to the DGC as follows: “DG Alarm Inputs” screw connection, input terminal

7 to Blue of w ater in diesel sensor. (note, any spare alarm input could be used)

12V terminal (Positive supply) to Brow n of water in

diesel sensor. GD terminal (Negative supply) to Black of w ater in

diesel sensor. (note, the negative supply also acts as the alarm input ground) (pairs are polarity sensitive, thus do not invert).

» Fit the w ater detection sensor ensuring that it is lying at

the bottom of the tank.

Note: » By placing the w ater detection sensor at the bottom of the

fuel tank, an alarm is generated once the probe tip is

submerged w ith w ater (+/-10-13mm required). The probe needs to be raised if a higher alarm detection level is required.

» The w ater in diesel sensor alarm state could be tested

using SAM2 RMS03 serial diagnostic and configuration software or LCD display.

25. SAM2 RMS03 – Hybrid Battery Management

One of the primary functions of the SAM2 RMS03 is Hybrid battery charge/discharge monitoring and control. The main purpose of hybrid control is to gain maximum

operational cost reduction by reducing generator operation and utilizing the backup energy sources, such as batteries, solar and w ind turbines in an intelligent and controlled manner.

Hybrid battery management is mostly used in the follow ing manner: » Cycling of the BTS load supply betw een utility grid AC

mains, generator AC mains and backup battery bank.

» Indoor shelter type sites have the added component, temperature, to be monitored and managed.

The Hybrid Battery Management control logic can be configured in the follow ing manner, using the SAM2 RMS03 serial diagnostics and configuration software:

» A – Hybrid control could be configured to include any monitored alarm condition or threshold as follow s:


Shelter temperature. Indoor shelter type sites run

the risk of high temperature conditions during a hybrid battery discharge cycle, due to air conditioners not running and not equipped w ith effective DC free cooling ventilation systems. A

shelter temperature could be configured (default

35C) at w hich the SAM2 RMS03 controller w ould suspend the hybrid cycle and start the generator to run the air conditioner unit.

Humidity. Typically for indoor shelter type sites, w hereby the generator would be started once

predefined humidity setpoint is exceeded. Rectif ier Override Control. The SAM2 RMS03

controller has the ability to except an external alarm/control signal to effectively control the hybrid

charge/discharge cycle. Override control is normally supported by hybrid rectif iers with the ability to control battery charge/discharge cycles.

» B – Hybrid control could be configured to use various

timers as follow s: Start and End Period. Due to excessive daytime

heat, indoor shelter type sites could be configured to activate a hybrid discharge cycle at certain times of the day only (nighttime w hen cooler). Tw o

independent daily time schedules could be configured.

Continuous. Hybrid cycle configured for continuous

operation, thus not time related. SAM2 RMS03 w ill activate battery charge/discharge based upon

monitored SoC (state of charge) or DoD (depth of discharge).

Alarm Inhibit. An alarm configured part of the inhibit

criteria w ill prevent a hybrid battery discharge cycle if active. The alarm needs to be present for a period

of 5min (default) before it has an effect on hybrid battery discharge activation. Only once the alarm has cleared for a period of 60min (default) w ould a

hybrid battery discharge cycle be activated. Any state change of the alarm in this group, during a hybrid battery discharge cycle would have no effect to discharge operation.

Alarm Suspend. An alarm configured part of the

suspend criteria w ill either prevent a hybrid battery discharge cycle from activating, or temporarily suspend the hybrid cycle once activated. The alarm has a programmable activation delay and requires to

be cleared for a period of 3min (default) before the hybrid battery discharge cycle would be activated. Any state change of the alarm during the hybrid battery discharge cycle would suspend hybrid

discharge and start the generator. Alarm Mask. Various alarms could be configured to

be masked during a hybrid battery discharge cycle. Alarms such as AC Mains and AC phase fail are masked. Reason being, these alarms are

automatically activated during a battery discharge cycle, but not relevant due to a controlled/scheduled event.

Boost Charge Cycle. Depending upon the battery

type being used for hybrid cycling, it may be necessary to periodically equalize or “overcharge” the battery to ensure it meets w ith the manufacturer’s specification and lifecycle. OPzV

batteries falls into this criteria and should be configured to be charged to 100% every x10 discharge cycles as a norm.

» C – Battery Monitoring. Default hybrid control utilizes the

follow ing battery criteria: Battery Bank Voltage. The battery bank DoD (depth

of discharge) is used to determine w hen the hybrid discharge cycle is ended, thereby starting the generator. The configured DoD is indicated as a

percentage to w hich the battery bank should be discharge. (do not exceed 80% DoD in order to prevent permanent battery damage)

Charge/Discharge Current. The battery current is continuously monitored during a battery discharge

and charge cycle. Effectively the calculated Ah

removed during a battery discharge is replaced during the battery charge cycle. The battery SoC (state of charge) is configured to replace the Ah removed during discharge plus the percentage offset

(overcharge), in order to compensate for equipment ineff iciencies.

» D – Utility Control. Utility grid AC mains pow er takes precedence over a hybrid battery discharge cycle. Once

utility grid AC mains fails: The generator is either started in test mode for 5

minutes (default) if it has not run in the last user configurable timeframe.

Hybrid battery discharge cycle activated, should all configured criteria be met (alarms, battery SoC) and

if the generator has run in the last user configurable timeframe.

Automated utility grid AC mains disconnect and

reconnect based upon configured upper and low er voltage limits.

» E – Generator Control. Remote start, stop and reset control of the generator. Automated control of the

generator w orks in conjunction with the monitored criteria as listed above.

» F – REC Control. Indoor shelter type sites DC ventilation system control (reduced energy cooling).

» G – Aircon Control. Indoor shelter type sites air conditioner control in terms of the follow ing: Aircon start/stop based upon shelter temperature.

Aircon single or dual operation based upon shelter

temperature. Aircon cycling based upon operational hours.

Aircon REC sw itchover based upon hybrid battery

discharge cycle and/or shelter temperature.

Hybrid Fail Reasons The SAM2 RMS03 controller has various reason codes as to w hy a hybrid battery discharge cycle does not activate. These

reason codes could be verif ied using the SAM2 RMS03 serial diagnostics and configuration software. The follow ing table refers to the meaning of each Hybrid Fail

Reason Code:

26. SAM2 RMS03 – Rectifier (SMPS) Alarm Monitoring

The SAM2 RMS03 controller through the cable termination unit makes provision to monitor three alarm indications from the installed rectif ier (SMPS). These inputs are dedicated to the SMPS, how ever should additional inputs be required, any

spare alarm inputs could be used for this purpose and configured accordingly. In general these dry contact digital alarm inputs are defined as follow s: (configurable using the SAM2 RMS03 serial diagnostic

and configuration software) R1 – Rectif ier 1 Fail (Module Fail - minor)

R2 – Rectif ier 2 Fail (System Fail - major)

HO – Hybrid Override (optional SMPS hybrid

control)


Installation Steps:

» Make use of the general purpose alarm cable (2-pair, part

of w iring cable kit) and connect to the “REC Alarms” screw terminal connection on the SAM2 RMS03 cable termination unit.

» Connect R1 (blue), R2 (orange), HO (optional, spare) and

DG (both blue/w hite and orange/w hite) » R1 refers to Rectif ier non-urgent and R2 Rectif ier urgent

alarms.

» Connect the other end of the cable to the relevant SMPS non-urgent and urgent alarm relay output contacts.

» The HO input refers to the “Hybrid Override” control,

normally obtained from a SMPS w ith hybrid cycling capabilities. This input is optionally used in conjunction w ith a hybrid pow er system. This means the hybrid battery charge/discharge cycle is determined by the

hybrid SMPS and used by the SAM2 RMS03 controller for hybrid reporting purposes.

27. SAM2 RMS03 – Generic Sensors Intrusion Sensor

A robust magnetic type reed sw itch is used to alert against intrusion. The intrusion sensor could be used in the follow ing applications: » As shelter door intrusion.

» As generator canopy intrusion.

Installation Steps:

» Make use of the universal alarm cable (2-pair, part of w iring cable kit) to connect the intrusion sensor to the SAM2 RMS03 cable termination unit S1(blue) and GD (blue/w hite) connection of the “Spare I/PS” screw terminal

connector. S1 refers to spare alarm input 1 and GD to ground connection.

» The intrusion sensor is by default an N/C contact and the alarm input needs to be configured accordingly on the

SAM2 RMS03 controller.

» When using multiple intrusion sensors as used on the generator canopy doors, ensure to use a single pair of

universal alarm cable to interconnect all the sensors in parallel. Connect the open-ended side of the cable to the generator controller “DG Alarm Inputs” screw terminal,

input 8 (brow n) and GD (brow n/white). Ensure that “DG1 Door” alarm is configured as N/O input on the SAM2 RMS03 controller.

Note: » Ensure to test the intrusion alarms by closing/opening the

shelter door, all the generator doors and view ing the status of the each alarm. Open each door individually to

confirm alarm activation (should the alarm not clear/activate accordingly, investigate wiring).

Movement Sensor

An indoor shelter type movement PIR (passive infra-red) or an outdoor perimeter type movement PIR is available, both uses quad zone logic and provides multi segmented detection

zones throughout the detection area. An alarm signal is created by the cumulative total IR energy of each zone. It is designed to provide 4-8 zones for a human sized object, in order to provide sharp and maximum signals

for stable detection. Spot temperature changes, i.e. by rodents etc., may affect only one or tw o zones at the same time creating a smaller detection signal, thus f iltering out false alarm detection.

The SAM2 RMS03 is configured (default) to keep a triggered movement alarm active for a period of three minutes. This action prevents multiple alarm events for the same condition

as movement occurs within the detection area. The triggered movement alarm w ould only be cleared if no movement has been detected for a period of three minutes w ithin the monitored detection area.

The SAM2 RMS03 provides the auxiliary 12Vdc supply to pow er the movement sensor.


Installation Steps: » Make use of the universal alarm cable (2-pair, part of

w iring cable kit) to connect the movement sensor to the

SAM2 RMS03 cable termination unit 12V (blue), GD (blue/w hite) and MA (orange) connection of the “Move” screw terminal connector. 12V refers to positive supply, GD to the negative supply and MA to the movement

alarm input. » Ensure to w ire the movement sensor according to the

same colors as indicated above. (Use a multi-meter to

verify polarity and DC supply output) Note: » Upon an activated alarm the SAM2 RMS03 w ill keep the

alarm activated until no movement is detected for the configured clear delay period.

Smoke Sensor

An optical smoke sensor is used due to proven stability in air movements associated w ith air conditioning systems, thus ideal selection for GSM BTS sites.

The sensor operates on the light scatter principal: Under normal conditions, light pulses in the Smoke Chamber do not reach the light sensor. With smoke in the Smoke

Chamber, light is deflected into the light sensor, triggering an alarm. The SAM2 RMS03 monitors both a smoke alarm, but also the

smoke sensor itself. Any malfunction or removal of the sensor from its base plate w ould result in an alarm (smoke detector alarm). The SAM2 RMS03 is configured (default) to keep a triggered

smoke alarm active for a period of three minutes, to ensure that no alarms are re-triggered as the smoke dissipates. The SAM2 RMS03 provides the auxiliary 24Vdc supply to

pow er the smoke sensor.


w iring cable kit) to connect the smoke sensor to the

SAM2 RMS03 cable termination unit +P(blue) and -N (blue/w hite) connection of the “Smoke” screw terminal connector. +P refers to positive supply and -N to the negative supply. GD is not used.

» Ensure to w ire the smoke sensor according, terminal (5) refers to positive supply and terminal (3) to negative supply.

» Use a multi-meter to verify polarity and DC supply output

from SAM2 RMS03 on smoke sensor. (ensure to measure 24Vdc – confirm correct polarity)

Note: » Should the smoke sensor detect smoke w ithin the shelter,

a smoke alarm w ould be activated (the red LED on the smoke sensor w ould be active). Once the alarm is

activated, it w ould remain active for a period of three minutes (user configurable) before the alarm w ould clear, provided no additional smoke is detected w ithin the shelter.

» Upon an active smoke alarm condition both air conditioner units and DC ventilation system is shut down as a failsafe measure against possible fire venting.

Panic Sensor A w ater resistant push type button is used for the purpose of emergency panic situations.

An alarm w ill be generated once the button is pushed, in order to alert the NMC of a possible emergency situation.

The alarm w ill auto latch for a period of tw o minutes (user configurable) once pressed, whereby it w ill automatically reset.


w iring cable kit) to connect the panic sensor to the SAM2

RMS03 cable termination unit S2(blue) and GD (blue/w hite) connection of the “Spare I/PS” screw terminal connector. S2 refers to spare alarm input 2 and GD to ground connection.

» Use the open-ended side of the cable and connect the blue and blue/w hite leads to N/C contact (blue and red leads) of the panic sensor. The N/O (green) lead is not

used and not connected.

28. SAM2 RMS03 – Mobile Phone SMS

29. SAM2 RMS03 – RBS Alarm Outputs The SAM2 RMS03 controller through the cable termination unit

makes provision to provide sixteen general purpose (transistor) RBS alarm outputs, to be w ired to the BTS radio external alarm inputs. The SAM2 RMS03 controller has the ability to map any of the

monitored alarm inputs to any of the sixteen RBS alarm outputs, using the SAM2 RMS03 serial diagnostic and configuration software. Multiple alarm inputs could be mapped to a single alarm output. The alarm outputs could additionally

be configured as N/O or N/C. (N/C advisable to ensure alarm status is activated during a SAM2 RMS03 controller malfunction)

Installation Steps:

» Make use of the RBS alarm input cable (20-pair w ith subD37 pin male connector, part of w iring cable kit) to connect to the “BTS/RBS External Alarms” SubD37 pin female connector located on the SAM2 RMS03 cable

termination unit. » Ensure w hen working w ith the 20-pair cable that all pairs

are tw isted together, thus avoiding split pairs and unnecessary fault f inding.

» Wire the open end of the 20-pair RBS alarm input cable to relevant RBS external alarm inputs via the existing “DDF” type connection block. (the DDF terminations vary

from RBS type) » Wire the 20-pair RBS alarm input cable according to the

follow ing color scheme: (pairs are polarity sensitive, thus do not invert positive and negative legs).

Note: » The above alarm connections are just an example of

possible interconnection to the RBS radio equipment via

a (krone block type) DDF. Other varieties could be used on various sites.

» The alarm connections need to be tested on the SAM2 RMS03 controller by activating each individually to

ensure alarm activation w ithin the BTS radio. » Each alarm output could be inverted from N/C to N/O

using the SAM2 RMS03 serial diagnostic and

configuration software in order to conduct the above mentioned test. (ensure to restore the configuration once completed)

» By using a multimeter, each alarm can be tested on the

“SAM2 RBS Alarm Ouputs” krone block. Active alarms should indicate 0Vdc and inactive alarms 5Vdc or 24Vdc

(RBS type dependent). (referenced to A-leg being positive and B-leg being negative)

» The RBS alarm outputs could also be tested by simulating an alarm state change (on/off) using the SAM2

RMS03 LCD display – Diagnostic - Test BTS Alarms, menu.
