1. Introduction

Overview

Lineage Power developed the Galaxy Power System EP4803 / EP4806 / EP4812 to support -48volt telecommunications powering solutions for the Indian market. The EP48XXX combines

fan-cooled, switchmode rectifiers, microprocessor control technologies, battery and load

disconnect/reconnect options in a modular front-access design. This modularity ensures easyaccess, simplified installation and maintenance, and allows the system to expand in capacity and

features as power needs grow.

The power system accepts alternating current from the commercial utility or a standby ac power

source and rectifies it to produce dc power for connected equipment. The systems control and

alarm functions interact with the rectifiers and the office. In addition, the system provides

overcurrent protection and charge, discharge, and distribution facilities. Battery reserveautomatically provides a source of dc power if the commercial or standby ac fails.

With 1200-ampere maximum capacity, distribution flexibility, Energy Monitoring features forthe AC input as well as DC Loads, the EP48XXX supports switching, transmission, and wirelessapplications in central office locations and environmentally controlled remote sites.

System Configurations

The EP 48XXX is available in two configurations:

The half height cabinet, shown in Figure 1-1 (EP4803 & EP4806) mounts on top of a

battery stand and can provide up to 600 amperes of dc power.

The full height cabinet, shown in Figures 1-2 (EP4812) is a standalone unit suitablefor floor anchoring, and can provide up to 1,200 amperes of dc power.

Figure 2-2 shows the electrical schematic for the Half Height Cabinets.

Figure 2-3 shows the electrical schematic for the Full Height Cabinets.

Each system contains ac distribution, dc distribution panels, a battery connection panel,

rectifiers, termination points for load circuits, and a system controller.

System Architecture

The architecture of the EP48XXX platform is based on the IC091_CB ICOMBO Controller,

which works as a front end master controller in addition to providing the user interface for

the plant.

The ICOMBO Controller provides complete control functionality, Distribution Monitoring &

Control. ICOMBO is a combination of features of Pulsar plus controllers family and add-on

modules (IEPSO). This approach of design gives a more centralized control and operation of

power system.

The ICOMBO works along with power system components and provides all the necessary

supervisory, measurement, monitoring and control functions as required by the India

Market. The feature set of the ICOMBO has been optimally designed considering the India

Market Requirements, with new and special features such as AC Energy Monitoring, DCEnergy Monitoring and Energy Efficiency.

This section describes the basic architecture of the EP48XXX Power Systems designed

around the use of the IC091_CB ICOMBO Controller.

The key features and specifications of the IC091_CB ICOMBO Controller are described in

the next chapter.

System Control InterfaceAlarm Outputs

There are a total of ten potential free relay outputs, which are wired up within the EP48XXX

plant, from the output terminal block to the HDR10 connector of the ICOMBO Controller.

All ten relays can be independently programmed to operate in normally open or normally

closed condition, by appropriately configuring jumpers 1-10 located on the ICOMBO board.

The configuration needs to be done as illustrated below:

Figure 3-3: Alarm Relay Configuration Jumpers for the ICOMBO

Figure 3-4: Configuring default active state for alarm Outputs


25/93


Each jumper corresponds to one alarm relay and each relay output can be configured

independently. The potential free contacts from the relay outputs are available at the

HDR10 connector of the ICOMBO controller. Out of the ten alarm relays, seven provide the

actual alarm condition, and three provide the severity associated with the alarm. The

severity relays transmit Power Critical (PCR), Power Major (PMJ), or Power Minor (PMN).

Each alarm is factory assigned a severity based on industry practices; however, they may be

reassigned to PCR, MAJ, MIN, or RO (Record Only). An alarm condition with the RO

severity results in the system controller transmitting the alarm without the severity but is

stored in the history log. PCR, PMJ nor PMN are transmitted with the alarm.

The seven selectable alarm relays are called User Alarm Relay 1 (R1) through User Alarm

Relay 7 (R7). Each relay can operate under one or more events/conditions or even when a

logical combination of certain events occur. Further, the active states for all the Relays are

user definable (either normally open or closed). Table 3-1 indicates the interconnection

between the I-combo Board and the user terminal blocks for the output relays. The factorydefault functionality for the relays is also indicated.

Main Menu

Access to alarms, warnings, equipment

status detail, basic control and operations

for maintenance purposes, and system

configuration can be obtained.

Note: the ICOMBO has the ability to have a

front Panel Password that limits

configuration as well as some operations. A

person with administrator level access can

enable this feature through the remote

interfaces. Standard ICOMBO controllers

are shipped from the factory with this

feature enabled.

Personal Identification (PIN)

The ICOMBO controller has the ability to restrict access from the front panel of the unit. It

has the ability to enforce a four digit Personal Identification Number (PIN) requirement for

users of the front panel for control/operations and configurable items. These

control/operations and configurations are generally considered the items that should only be

done during initial install or by specific personnel. This feature is shipped enabled from the

factory in the standard ICOMBO controller. The factory default for the PIN is 1234. Each

position of the password is configurable between 0~9. A sample screen like that following is

required for PIN access.

The up, down, left and right arrows are used to enter the appropriate password. Uponentering a correct PIN the following momentary screen shows up and then disappears

leaving the user at the menu location prior to entering the PIN.


30/93


Once a user enters the PIN, total front panel access is allowed for as long as the user remains

in menus other than the default menu and/or any one of the following :-

a) The front panel access will remain open once the PIN has been entered till the time out

value. The Icombo controller has a factory configured default of 120 minutes.

b) An internal counter shall be kept and reset if the user leaves the default menu and returns

to others menus before the timeout period is reached.

Contactors

The ICOMBO controller monitors and controls contactors. Contactor controlled by appropriately

configuring a unique board ID and associating it to a specific contactor function at the controller.

ID1-6 Associates the ID numbers set on the controller to one of four independentset of contactor controls.

These contactor controls are:

LVBD (Low Voltage Battery Disconnect),

LVLD1 (Low Voltage Load Disconnect 1),

LVLD2 (Low Voltage Load Disconnect 2), and

LVLD3 (Low Voltage Load Disconnect 3).

The ICOMBO has assigned each unique board ID number as follows:

ID1 to LVBDID2 to LVLD1ID3 to LVLD2

ID4 to LVLD3

DisconnectsThis section of the configuration menu contains the parameters associated with the individual

function assignments made in the previous section. Each LVD type (LVBD and LVLD1-3) canindividually be enabled or disabled. Only the LVBD and LVLD1 are enabled from the factory.

The LVDs disconnect and reconnect method of operation used by the controller can be

configured for each assignment. The method of disconnect or reconnect can be based on the

traditional means of reaching a system bus voltage threshold (Voltage) or based on both reachingthe system bus voltage threshold and an elapsed time from once the system has been placed on

discharge (BD) and at least two or more rectifiers are reporting AC failures (Voltage/Time). The

same Voltage and Voltage/Time mode of operation can also be selected for reconnecting LVDs.In this case the elapsed time configured is the time from once the reconnect voltage threshold has

been reached. Note: selecting None for a reconnect mode will require manual intervention to

shut the contactor. Selecting None for the disconnect mode will not allow a LVD to open. TheICOMBO has factory defaults of the following:

LVBD (Enabled) Disconnect Mode (Voltage); Range: Voltage, Voltage/Time, None

Shutdown AlarmWhen enabled, the Imminent Shutdown Alarm is generated prior to

opening the LVBD. Once the LVBD threshold has been reached, the alarm

is generated. The alarm is issued 15 seconds prior to opening the contactor

to provide an indication that system shutdown is imminent due to asystem battery disconnect. The alarm is based on the configured LVBD

battery disconnect threshold.

The factory default for this feature is Disabled.

Remote Emergency

Power Off (EPO)

If enabled, the remote Emergency Power Off (EPO) feature allows the

controller to detect the occurrence of a contact closure between J3.5 and

J.10 and force open all battery contactors in the system. The battery

contactor will open five seconds after the contact has been asserted. Oncethe contact is removed, the battery contactor will be re-asserted to itsprevious operational state.

The factory default for this feature is Enabled.

BoostThe Boost function allows battery charging to be expedited by raising the system voltage to

boost level for a set time. The following boost mode parameters are set in this area of the menusystem:

Set Point Primary DC bus voltage set-point during the Boost mode of operation.Boost (set point) is adjustable from -48.00V to -58.00V in 0.1Vincrements.
