2. Product Description

The PowerBox is a power controller device dedicated to multiple zones heating. It manages up to 24 monophased or triphased “zero crossing” loads up to 2000 amperes:

o Elimination of harmonics, o Prevention of power peaks, o No flickering of the power grid, o Optimization of the real power share, o Automatic load recognition, o Smart Power Limitation.

2.1.


PowerBox 26/07/2020 81229466B

Functions

In order for the PowerBox to be adapted as best possible to the required application, it has numerous functions. These functions are described in this chapter.

2.1.1. Heating load optimization for multiple zones

The PowerBox optimizes global electrical system by intelligent heating load management. This powerful processing unit with special algorithm enables you to reduce energy costs. Synchronized simultaneous heating loads and individual capacity set free the potential to save energy (not just by simple performance limit but by intelligent synchronization of the electric loads):

o The PowerBox prevents power peaks before it begins, o Optimization of the efficiency with power factor to 1,

o Short amortization of the investment,

o The instantaneous power is kept inside the supply limits.

The concept of the PowerBox is little more expensive control unit in combination with cost-effective solid state relays.

2.1.2. Heating load management for multiple zones The PowerBox measures, calibrates and memorize once for all its various loads’ resistive value and behaviour. This Auto-Calibration function is only necessary once during commissioning.

o One push on the button is enough and within a few seconds the self-learning routine collects all process parameters.

The PowerBox operates with various load configurations. The user selects the operating mode most suitable to adapt the device to the various applications and manufacturing processes, as well as to different electrical loads:

o Monophased mains with up to 24 monophased loads, o Triphased mains with up to 24 two-phases controlled loads in star or delta

connection,

o Triphased mains with up to 24 three-phases controlled loads in star or delta connection,

o Triphased mains with up to 8 three independent monophased loads in open delta

connection,

o Triphased with neutral mains with up to 8 three independent monophased loads in star connection.


PowerBox 26/07/2020 81229466B

To sum-up, the PowerBox simultaneously commands up to 24 loads with 1-2-3 phases control thanks to cost-effective zero cross static relays. The load shedding management strategy is very easy to use. The user does not need to study manuals, or to have knowledge about the various synchronization methods. Just start in the “Easy mode”. The power requests of the single loads are just read and written via interface to the PowerBox:

o Adjust the maximum power allowed at the power limit.

o One current sensor for 8 loads.

o Every control zone is administered separately

▪ Calculation of instantaneous current (min/max), voltage, power... ▪ Calculation of the load resistance for heater control (HB). ▪ Power meter and current meter per zone. ▪ Communication via TCP/IP and 3 serial interfaces.

▪ Modbus, DeviceNet and Ethernet/IP are available as option (Modbus Master and Slave).

PowerBox 26/07/2020 81229466B

2.1.3. Real time Zero Cross firing and synchronizing OLAS (Optimal Live Automatic Synchronisation) on all controlled zones allows the following features:

o The load current is almost sinusoidal Optimized timing of synchronization ensures the best possible effective power,

o The instantaneous power is very close to the absolute mean value, o Elimination of harmonic waves, o Power saving by reducing of harmonic waves, o No mains flickering, o Optimized start-up behaviour for heating loads with low resistance to cold

(e.g. short wave IR-radiators).

Each individual load may be controlled independently by: o An open loop based on conduction rate from 0 to 100%, o A closed loop based on:

▪ Active power in Watt, ▪ Rms current in A, ▪ Rms voltage in V.

Synchronization is real-time and do not disturb the process. The PowerBox commands its relays so that the global instantaneous current is nearest to the active current delivered to the loads without changing required setpoints:

Above, the global current on the mains without and with PowerBox’s real-time synchronization Max current on the mains is approximately equal to average current delivered to the loads, which minimizes electrical architecture over sizing.


PowerBox 26/07/2020 81229466B

Synchronization optimizes the soft start function integrated inside the PowerBox which limits overcurrent due to fast Infrared resistive loads. Using a PowerBox with multiple loads will limit inrush global current as if only a single load was heating on the mains! Above, the inrush global current with infrared resistive loads without and with PowerBox’s real-time synchronization


PowerBox 26/07/2020 81229466B

2.1.4. Real time measurement and fault detection The PowerBox measures a single instantaneous current for each group of 8 loads:

o A single current sensor measures up to 8 individual loads’ current thanks to a smart algorithm (1 PowerBox = up to 3 current sensors = 24 loads),

o Real-time calculation displays all electrical measures from ohmic value to rms

current, active power and kWh energy all the time whatever the Setpoint is (no process perturbation).

Thanks to this measurement function, Partial or total Load Failure (PLF) detection operates for each individual load which is controlled by the device:

o Each ohmic value is compared to an internal model which evolves with :

▪ The Setpoint (fast infra-red loads), ▪ The load’s age (Si-C).

o Thanks to the threshold and timer parameters, PLF may send an alarm for a 10%

load break in 5s or 5% load break in 10s etc.

o A 100% load failure is detected separately and faster than any PLF.

o PLF detection operates at any Setpoint down to 2% of conduction rate.

2.1.5. Communications

The PowerBox is designed for DCS and/or PLC interfacing thanks to its various serial and Ethernet industrial communications:

o Serial Communications ▪ COM1 RS232 9600bds with Modbus-Serial (standard feature),, ▪ COM2 which must be specified when ordering between the following

options: o RS485/422 9600bds with Modbus-Serial (standard feature),, o Profibus-DP (Option available without any delay), o CanOpen (Option available with delay), o RS232 Master with Modbus-Serial (Option available with delay).

o Ethernet Communications

▪ Modbus-Ethernet Slave (standard feature), ▪ Ethernet-IP (Option available with delay), ▪ Profinet I/O (Option available with delay), ▪ Modbus-Ethernet Master & Slave (Option available with delay).

PowerBox 26/07/2020 81229466B

2.3.2. Loads Management

Once an operating mode is selected among the various configurations, all mono or tri-loads must be distributed homogeneously among the different groups A, B and C. Each current sensor has a constant precision so that minimizing the number of loads measured simultaneously by the same current sensor will optimize its calculations. Having 2 current sensors to control a tri-load is the best solution for a precise partial load failure and a closed-loop power regulation process. Having 1 current sensor to control a tri-load is an interesting and economizing solution in order to detect approximately a partial load failure while operating an open-loop conduction rate regulation. For instance, different solutions may coexist to control and command 12 mono-loads which are decomposed as 2x50kW, 2x25kW and 8x8kW:

o Group A = 8x8kW loads + Group B = 2x50kW & 2x25kW loads: ▪ 2 current sensors used.

o Group A = 8x8kW loads + Group B = 2x50kW loads + Group C = 2x25kW loads : ▪ 3 current sensors used.

o A & B groups share all loads homogeneously: ▪ 2 current sensors used.

o A, B and C groups share all loads homogeneously: ▪ 3 current sensors used.

All solutions will work correctly. However the two last configurations will offer the most homogeneous current measurement system using the same current sensor model. The third solution stands for the cost-effective optimal solution. For instance, different solutions may coexist to control and command 8 tri-loads which are decomposed as 2x50kW, 2x25kW and 4x8kW with 400V phase/phase connection:

o M3P Mode: all tri-loads are decomposed into 3 mono-loads which represents 24 mono-loads whose Setpoint may be the same. Group A, B and C get respectively 2x50kW + 2x25kW + 4x8kW mono-loads:

▪ 3 current sensors are used, all loads are controlled separately and partial load failure is optimal. One static relay per phase.

o T2P Mode: 2x50kW + 2x25kW + 4x8kW tri-loads with 2-Phases controlled: ▪ 2 current sensors used on L1 & L3 phases to detect partial load failure

precisely whatever the delta or star connection. L2 common phase without any static relay.

o T2OPT Mode: Group A, B & C share all 8 loads homogeneously: ▪ 3 current sensors used, all positioned on L1. L2 common phase without

any static relay. o T3P Mode: 2x50kW + 2x25kW + 4x8kW tri-loads with 3-Phases controlled:

▪ 2 current sensors used on L1 & L3 to detect partial load failure precisely whatever the delta/star connection. 1 static relay per phase.

o T3OPT Mode: Group A, B & C share all 8 loads homogeneously: ▪ 3 current sensors used, all positioned on L1. 1 static relay per phase.

All solutions will work correctly. The T2OPT & T3OPT solutions stand for the cost-effective optimal solution when tri-loads are more than 8. The M3P Mode stands for the cost-effective optimal solution when all loads’ partial load failure & short circuit detection must be controlled (one static relay & one current sensor per phase will detect any short circuit to ground).

2.3.3. Current Sensors Selection

In order to optimize current measurement, the choice for a current sensor’s model and nominal value will take into account the sum of the maximum instantaneous peak current for the 8 loads of each group. A margin of 25% will be enough. Resistive Elements with High inrush current: infrared resistors for instance have 5 times to 10 times current variation when cold. In order for the PowerBox’s synchronization to be best used when resistors are cold, all infrared loads should be on the same synchronization group so that global peak current will not exceed one resistor’s peak current. The PowerBox optimizes heating:

o When a group of N < 8 infrared loads is used, global inrush current measured by the sensor will not exceed (10*nominal current of one resistor), which represents:

▪ Global inrush current = 10/8 = 125% of one resistor’s nominal current when 8 loads are on the same group!

o In that case, using infrared loads instead of constant resistive loads will not

change the selection for a current sensor model’s nominal value: ▪ Current sensor’s nominal value = 8 loads * 125% nominal current =

1000% nominal current = 10x nominal current of one resistor! Current sensors’ models are detailed below:

o Up to 600A : unipolar rectangular model HASS 10x20mm

o From 200 to 1500A : bipolar models :

▪ Rectangular HAT 30x40mm

▪ Round HTA up to 32mm diameter

Wiring details and mechanical dimensions may be found in Current Sensors’ Annex. Consult us for another current sensor model.

Caution! All other values are considered as No Heating Modes (= 0).


PowerBox 26/07/2020 81229466B

o VMAX (@245): Enter maximum speed variation of the Setpoint (Regulation Ramp)

in 0.1% per second. VMAX’s default value equals 500 = 100% in 2s.

o TRDEM (@256): Enter delay between heating start-up and partial load failure &

short circuit detection. TRDEM‘s default value is 15s.

o TPLF (@257): Enter partial load failure timer (see ERRPLF). TPLF’s default

value is 15s.

o PMUL (@278): Enter unit used to display power measures, setpoints and limits:

• 0: en W, de 0 à 32000W (32kW max)

• 1: 10W, de 0 à 32000kW (320kW max)

• 2: 0.1kW, de 0 à 3200kW (3.2MW max)

• 3: kW, de 0 à 32000kW (32MW max)

• PMUL’s default value is 2, which means 0.1kW (1000 = 100.0kW).

o TRCC, IRCC (@280, 281): Define short circuit detection behaviour thanks to its

two parameters:

• IRCC is the detection’s threshold in 0.1A.

• TRCC is the detection’s timer: 100 = 100x10ms = 1s.

• When there is no static relay delivering current to its load, a short circuit error will happen if the PowerBox measures a current which is greater than this threshold during a period which exceeds the detection’s timer TRCC.

• IRCC’s default value is 500 = 50.0 A.

• TRCC’s default value is 10000 = 10s.

• When IRCC is 0, the detection is disabled.

o IMAX (@282): Enter current sensors’ maximum allowable current in 0.1A:

• IMAX’s default value is 5000 = 50A.

• When one current sensor measures an overcurrent greater than this threshold, an overcurrent error will be displayed. Heating will be stopped immediately.

• When IMAX is 0, the detection is disabled.

o ERAUTO (@287): Enter Auto-Calibration’s maximum allowable error.

• ERAUTO’s default value is 50 = 5.0%.

• When an Auto-Calibration is started, all active loads’ ohmic value will be calculated and displayed in accordance with the internal resistor’s model. AC = 1, CALEND = 0, CALOK = 0.

• At the end of the Auto-Calibration, the PowerBox stores all loads’ ohmic value, model value and ohmic error. If a single active load’s ohmic error is greater than ERAUTO threshold, the Auto-Calibration is considered ended but not Ok. AC = 1, CALEND = 1, CALOK = 0.

• Otherwise the Auto-Calibration is considered ended and Ok. AC = 1, CALEND = 1, CALOK = 1.

• If Auto-Calibration is Ok, put AC = 0 to begin normal heating process. Otherwise, ERAUTO may be adjusted in order to end Auto-Calibration with CALOK = 1.


PowerBox 26/07/2020 81229466B

• Load management Registers:

Changing loads’ parameters requires the following instructions:

• Enter new value in the global parameter (listed below): if the value is different from the older one, the change concerns all 24 possible loads.

• Enter new value in only one load’s parameter without changing this same parameter for the other 23 loads: enter this value at the Modbus address = Global parameter’s address + Load’s Number.

• To change maximum current to 400A for all 24 loads, enter 4000 (0.1A) at the Modbus address 775 / 0x307. If the value was already 4000, there is no change.

• To change maximum current to 400A for only the 4th load among 24, enter 4000 (0.1A) at the Modbus address = 775 + 4 = 779 / 0x311.

o ENABLE (@500): Very important! This register specifies which loads are

active/enabled (Bit = 1) and inactive/disabled (Bit = 0).

o REGUL (@650): Very important! This register specifies which regulation mode

is used to control heating process:

• 0: Conduction Rate (default mode): the Setpoint ranges 0.0% to 100.0% as a modulation (1000 = 100%).

• 1: Active Power Regulation: the Setpoint ranges from 0 Watt to 32kW but should not exceeds the maximum power dissipated by the load at nominal point which is a physical limit. The unit used for the setpoints depends on PMUL register’s value. Power regulation takes automatically into account the load’s resistive variations.

• 2: Active Current Regulation: the Setpoint ranges from 0.0A to 3200.0A but cannot exceed the maximum current dissipated by the load which is a physical limit. Current regulation takes automatically into account the load’s resistive variations.

• 3: Rms Voltage: the Setpoint ranges from 0.0V to 3200.0V rms voltage applied on the load but cannot exceed the mains’ maximum voltage which is a physical limit. Instantaneous voltage is still similar to the mains but rms voltage is modulated according to the Setpoint. In that case, the load’s resistive variations are no longer taken into account.


PowerBox 26/07/2020 81229466B

o IMAX (@775): This register specifies the maximum current allowable for each load, in 0.1A.

• If one load’s current exceeds this threshold, corresponding zone will be stopped and an individual alarm will be displayed.

• Set to 0, this detection is disabled.

o RTYP (@800): Very important! This register stands for all loads’ internal model

which impacts current, power and ohmic value calculations:

• 0: Constant resistive loads. Whatever the Setpoint and operating conditions, this load’s ohmic value will vary less than 10% or 20% during its whole working life.

• 1: infrared resistive loads. According to the Setpoint and the operating conditions (Temperature of the furnace etc.), this load’s ohmic value may vary very strongly up to 10 times at cold start-up.

If RTYP is wrong, Auto-Calibration will never end correctly and all detections from partial load failure to overcurrent will behave strangely. RTYP must always be checked before launching Auto-Calibration sequence or heating regulation process.

o ERRPLF (@875): this register concerns Partial Load Failure detection such as

TPLF register.

• ERRPLF’s default value is 100 = 10.0%.

• This is the PLF threshold. When a load’s ohmic error exceeds this threshold during a period that exceeds TPLF timer, an alarm is displayed.

o PMUL (@900): This register specifies the unit of all individual loads’ power

measures (see PMUL register):

• 0: en W, de 0 à 32000W (32kW max)

• 1: 10W, de 0 à 32000kW (320kW max)

• 2: 0.1kW, de 0 à 3200kW (3.2MW max)

• 3: kW, de 0 à 32000kW (32MW max)

• PMUL’s default value is 0, which means 1 Watt (1000 = 1000 Watt).

PowerBox 26/07/2020 81229466B

o R/S: Global Run / Stop

Set R/S to 1 to start heating all loads whose individual R/SZI is also at 1. Set R/S to 0 to stop heating all zones whatever their individual R/SZI.

o CLEAR: Clear Faults

When a fault occurs, reinitialize according to the following sequence:

1. Set R/S at 0. 2. Set CLEAR at 1 which clears any fault detected. 3. Set CLEAR at 0 when the electrician/technician has corrected the problem. 4. If fault occurs again, the problem must be solved before starting heating

again. 5. If the fault has disappeared, heating may start again. 6. CAUTION! If CLEAR remains at 1, R/S command will be ignored.

o AC: Auto-calibration

To start auto-calibration sequence:

1. Set R/S at 0 & check that no fault has occurs. 2. Set AC at 1 to start auto-calibration sequence, 3. If AC is set at 0, auto-calibration will stop immediately whereas PowerBox’s

calibration won’t be efficient. 4. When an Auto-Calibration is started, all active loads’ ohmic value will be

calculated and displayed in accordance with the internal resistor’s model. AC = 1, CALEND = 0, CALOK = 0.

5. At the end of the Auto-Calibration, the PowerBox stores all loads’ ohmic value, model value and ohmic error. If a single active load’s ohmic error is greater than ERAUTO threshold, the Auto-Calibration is considered ended but not Ok. AC = 1, CALEND = 1, CALOK = 0.

6. Otherwise the Auto-Calibration is considered ended and Ok. AC = 1, CALEND = 1, CALOK = 1.

7. If Auto-Calibration is Ok, put AC = 0 to begin normal heating process. Otherwise, ERAUTO may be adjusted in order to end Auto-Calibration with CALOK = 1.

8. Caution! If AC remains at 1, R/S command will be ignored and heating process cannot start.

o FM: Memorize registers’ value into Flash memory

Before launching heating process, adjust all necessary parameters, start auto-calibration and finally memorize all changes according to the following sequence:

1. Set FM register from 0 to 1 to initiate memorization request. 2. Wait for FMOK signal to go 1, which means end of memorization. 3. Set FM at 0 to end memorization sequence.

Note: memorization cannot be done while R/S is 1 and heating processing.


PowerBox 26/07/2020 81229466B

o ISENS: Current sensors used

• ISENS = 0 (commissioning tests): current sensors are disabled. The PowerBox uses its internal resistor’s model to control and command the loads. All detections from partial load failure to overcurrent and short circuit are disabled. This mode should only be used during commissioning tests. Auto-Calibration doesn’t work.

• ISENS = 1 (default value for heating process): current sensors are enabled. The PowerBox measures its currents in order to compute all electrical values from power, current to ohmic value of each load. All detection from partial load failure to overcurrent and short circuit are working precisely. Auto-Calibration will operate normally.

o PLIM: Power Limit o LS: Load shedding Enable/Disable

PLIM is a Word register dedicated to store PowerBox’s global power limit when load shedding is enabled. Just set this PLIM to 10000 = 10kW for instance and the PowerBox will limit its global power dissipated in all its loads to this limit.

According to PMUL, PLIM’s unit will be 1 Watt, 10 Watts, 100 Watts or 1kW.

o R/SZi: Individual Run / Stop for each Zone

In order to start or stop each load individually, R/SZi stands for each load’s ON/OFF command. However, when global R/S is OFF, R/SZi cannot start one load’s heating process. If global R/S is ON and R/SZ8 is set to ON, the 8th load will start heating.

o SPZi: Individual Setpoint for each Zone

All loads are controlled individually. SPZi registers stand for this individual Setpoint. If a group of loads must be control with the same Setpoint, just set all the corresponding setpoints with the same value. SPZi’s unit depends on the regulation mode:

o Conduction Rate : from 0 to 1000, in 0.1% (1000 = 100%) o Power regulation : from 0 to 32767, in W, 0.1kW or kW (see PMUL) o RMS Current regulation : from 0 to 32767, unit in 0.1A (1000 = 100.0A) o RMS Voltage regulation : from 0 to 32767, unit in 0.1V (1000 = 100.0V)

3.4.2. Control Registers (PLC & DCS INPUTS)

o UN: Mains Voltage measure

UN is a 16 bits signed register that stores network voltage measure in 1/10V. This value is measured between 2 phases or between phase & neutral according to selected mode.

o GP: Global power measure

GP is a 16 bits signed register that stores active power dissipated by all Zones in 1/10 kW (10000 = 1000kW). o GI: Global Current measure

GI is a 16 bits signed register that stores active current consumed by all Zones in 1/10 A. In T2OPT & T3OPT triphased operating modes, the 3 phases are supposed to be well-balanced. (10000 = 1000A).

o PF: Power Factor

PF is a 16 bits signed register that stores power factor in 1/10%. Thanks to PowerBox’s synchronization function, a smart firing of all loads is managed on the electrical network in order to reduce Flicker effect, to guarantee optimal power factor PF > 95% and to minimize energetic costs on the whole installation. o KWH: Energy Consumption

KWh counter is stored as a 32 bits register that you can access through two 16 bits registers. Its precision is 1/10 kWh. This data do not resets to 0 when power shuts down as it is stored in Flash memory. It can be reinitialized.

Its maximal value is 2 147 483 648 Wh ~ 2 140 000 kWh ~ 2 MWh, which stands for a 1MW installation working at 100% during 3 months.

o AL: General Alarm

AL remains at 0 as long as the PowerBox operates normally. As soon as a partial or total load failure happens on a single load, AL goes 1.

This alarm will not stop heating process. As soon as the problem is over, AL goes back to 0.

o ERR: General Error o ERRGV: Mains Voltage or Frequency Error o ERRSC: Short Circuit Error o ERRGI: Global Current Error

When an error occurs, ERR register goes 1. Fault discrimination is detailed below:

• ERRVG: as soon as the power supply AC voltage stops crossing 0V for at least 25ms at 50Hz, ERRVG displays an error. This is a power supply missing error. Normal heating is compromised and cannot start or continue.

• ERRSC: as soon as the PowerBox measures a current which exceeds its short circuit threshold, ERRSC displays an error. This is a short circuit error. Normal heating is compromised and the problem must be solved before reinitializing heating process. It might be a ground fault or isolation fault concerning a group of loads.

• ERRGI: as soon as the PowerBox measures a current that exceeds the overcurrent threshold, ERRGI displays an error. This is an overcurrent error.

When an error occurs, the operator in charge of the PowerBox must find and solve the electrical problem before trying to reinitialize the process. The PowerBox should not start heating until all remaining fault conditions are repaired on the whole installation. (See CLEAR)

o LSEFF: Global Power Limit

LSEFF is a status register which represents global power limitation function, the so-called Load Shedding LS function. When load shedding or global power limitation is enabled, LSEFF goes:

• 1 if loads’ Setpoints exceeds PLIM power limit value. This means that the PowerBox is limiting the total power delivered to the load and doesn’t respect the Setpoints.

• 0 if loads’ Setpoints do not exceed PLIM power limit value. This means that even if Load shedding function is enabled, the PowerBox is not currently limiting the power delivered to the loads because PLIM is not reached.


PowerBox 26/07/2020 81229466B

o CEND: End of Calibration o COK: Correct Calibration

When an auto-calibration is started with AC register, the PLC must check these two registers CEND and COK to display:

• The end of the calibration CEND = 1,

• A correct calibration COK = 1.

See Auto-Calibration AC Output for further details on the Auto-Calibration sequence.

o FMEM: End of Memorization

When a memorization is started, FMEM status register will display 1 at the end of this sequence. See FMEM Output for further details on the memorization sequence.

o DI1, DI2, DI3, DI4: Digital Inputs

These status registers display the value of the corresponding digital inputs.

o RUN: Heating Status

This status register displays whether a regulation is in process (1) or not (0).

3.4.3. Measurements & Control Registers for each individual zone

The 3 groups A, B or C have individual status registers and regulation feedback which are detailed in the tables below.

o ALZ1 to ALZ8: Individual Alarm for each load When an individual alarm happens, corresponding ALZi register goes 1. This alarm means that the Powerbox has detected on this load:

• A total load failure (no current is delivered to the load)

• A partial load failure (See PLF detection parameters for further details)

The alarms will not stop the heating process.

PowerBox 26/07/2020 81229466B

o ERRZ1 to ERRZ8: Individual Error for each load When an individual error happens, corresponding ERRZi register goes « 1 ». This individual error stands for an overcurrent on one load whose measured current is greater than the threshold. This load stops heating as soon as the error happens. Therefore, to reinitialize individual error flag the operator must:

• Put « 0 » in corresponding R/SZi register then put it back to « 1 »,

• Put « 0 » in global Run/Stop R/S register then put it back to “1”.

CAUTION If such error happens, the operator must look after the technical problem related to the overcurrent. As long as the problem is not solved, the reinitialize sequence must not be done. Check that the threshold’s value and the resistor model match the load’s specification.

o PZ1 to PZ8: Individual active Power delivered to each load PZi are 16 bits registers which represent the active power delivered to the corresponding load. Its default value is in Watt and it ranges from 0 to 32767W.

o RZ1 to RZ8: Resistive value measured for each load RZi are 16 bits registers which represent the ohmic value of the corresponding load. Its unit is 1/100 Ohm and it ranges from 0 to 327.67 Ohm.

4.2. Profibus-DP

4.2.1. Getting started with Profibus-D

This function inserts any PowerBox in a Profibus-DP network without any extern gateway. Thanks to its Profibus-DP standard SUB-D9 female connector on COM2, any PowerBox supports Profibus-DP slave protocol so that Profibus-DP master can access all INPUTS and OUTPUTS as described in the GSD file. Therefore, any DCS can monitor PowerBoxes with high digital precision (up to 16bits for Setpoints).

4.2.2. Wiring details

Profibus-DP has an automatic baud rate selection between 9.6kbds and 12Mbds. Each PowerBox is identified on the network thanks to its identifier which ranges from 2 to 99. (See Profibus Identifier on the Parameters’ chapter). See below Profibus-DP female connector’s signals & position on PowerBox’s front panel: Profibus-DP Line is a differential pair (RS485): cabling PB+ & PB- (Pin 3 & 8) and adding termination resistors at both ends of the bus will have it work.

4.2.5. Compact Profibus GSD file Standard Configuration

According to the number of loads managed by the PowerBox, PLC & DCS must use two of the

following INPUTS & OUTPUTS modules:

When selecting 8 zones, only group A will be working. When selecting 16 zones, both groups A and

B will be working. Group C will only be working when 24 zones are selected.

PowerBox’s Profibus-DP specifications are:

• Profibus-DP slave functionality (DP-V1),

• Profibus-DP Standard Sub-D9 female connector,

• Maximum active stations : 126,

• Maximal stations number by segment : 32,

4.2.6. First steps to validate Profibus-DP

At first do not connect PowerBox’s outputs to the static relays right now. The first steps in order to validate Profibus-DP communication with PowerBox are:

1. Wiring PB+ & PB- on PowerBox’s COM2, 2. Selecting Baud rate which ranges from 9.6kbds to 12Mbds,

3. Selecting IN/OUT modules from the GSD file:

a. PBX 16 ZONES IN , b. PBX 16 ZONES OUT.

4. Finding PowerBox on the network thanks to its ID.


PowerBox 26/07/2020 81229466B

5. Creating PLC’s internal variables according to PowerBox’s Profibus Table and IN/OUT modules:

a. See image below:


PowerBox 26/07/2020 81229466B

6. Begin virtual heating without connecting static relays to the PowerBox: a. Sending “1” in the 2.5 Bit register “COM ALIVE” to enable Profibus exchanges with

PowerBox, b. Sending “0x1F” in 3 & 20 Byte registers “R/Szi 1 to 8” & “R/Szi 9 to 16” to enable

10 loads divided as 5 loads group A and 5 loads group B, c. Sending “100” in 4, 6, 8, 10, 12 & 21, 23, 25, 27, 29 Word registers to change the

10 corresponding setpoints 1 to 5 in group A and 9 to 13 in group B, d. Sending “1” in general R/S to begin a virtual no sensor heating process.

At this moment, the PowerBox should be sending 10 commands on first 5 Outputs from group A & B without close loop current measure. Modifying setpoints will check that all outputs answer correctly. Next step would be wiring current sensors, connecting outputs to the static relays & finally sending “1” in Bit register “Sensor used” to enable close loop current measure.

4.2.7. FAQ Frequently Asked Questions

What about “ALIVE COM” register at Profibus address 2.5?

Output Bit register ALIVE COM must always be set to “1” in order for the PowerBox to communicate through Profibus-DP.

What happens when Profibus-DP communication fails while heating is in process?

The PowerBox should always be considered as an actuator. If communication is broken, the PowerBox will remain in the last state of the outputs before communication has failed. The DCS / PLC / HMI must detect this failure and decide whether to carry on heating process or cut security chain to disconnect mains from the loads. As long as no damage happens on the SCR relays, the PowerBox will apply orders. As soon as SCR relays are damaged, the PowerBox will stop heating by itself and will send failure information if Profibus-DP communication works.

4.5. Embedded Ethernet WEB Server

4.5.1. What is the purpose of PowerBox’s WEB Server

In order to parameterize the PowerBox during its commissioning, the operator can access a short list of parameters thanks to the web server integrated in the device. Enter the IP address of the device inside the web browser (for instance internet explorer): the main page will appear. In factory settings, the IP address is 192.168.0.100. However, before delivering the PowerBox, a dedicated IP address is selected and figures in the quality test document delivered with the PowerBox. The PowerBox’s web server is separated in three parts:

1. At first, “Power Control Settings” represents eight major parameters that define a client’s application:

a. “Network/Load/SRR Configuration” determines whether you have a monophased or triphased network, one to twenty four SRR relays and star/delta/open-delta load schemas.

b. “Resistor Model” selects infra-red or Constant resistor model to compute all electrical measures based on an internal algorithmic model.

c. “Regulation Mode” identifies whether the PowerBox will regulate its SRR thanks to the conduction rate [0-100%], the active power, rms current or rms voltage.

d. “Voltage Scale” enables operators to adjust main’s voltage measure to have more precision in closed-loop regulation and partial load failure diagnostics.

e. “Partial Load Failure (PLF) Threshold & Timer” define the PLF alarm sent to the PowerBox when the error between resistor measure and model is greater than the Threshold’s value during a period of time greater than Timer’s value.

f. “Short circuit Threshold” enables or disables SRR relays failure diagnostic: when the current measured when no relay is heating is greater than this threshold, the PowerBox sends a short circuit alarm.

g. “Profibus Identifier” defines different PowerBoxes in a Profibus-DP industrial bus.

2. Then “Multi Zones Settings” details the use of the 3 Current Sensor inputs and the 24 SRR relays Command outputs available in the PowerBox. In order to adapt the PowerBox measures to various current sensors, the operator must selects its application’s “Sensor Type & Scale”.

Finally “Ethernet Settings & Memorization” details the Ethernet IP and Mask addresses that enable the operator to access the Web Server. The memorization item must be uppermost in operators’ mind as it allows all modification to be memorized by the PowerBox even after power shut down. Last but not least, the MAC address identifies the PowerBox on the Ethernet network and also stands for the Product code for after sales matters.


PowerBox 26/07/2020 81229466B

4.5.2. Display the WEB Server via a WEB Browser

Enter IP Address under your Web Browser:

You will access PowerBox’s embedded Web Server:

This Web server is separated into 3 parts:


PowerBox 26/07/2020 81229466B


PowerBox 26/07/2020 81229466B

4.5.3. Getting started with the WEB Server

To modify one parameter, the operator must shut down Run/Stop register if running. Then the operator has to change the parameter value and finally validate thanks to “Submit” button.

If the value is wrong, the operator may press the reset button to come back to the original setting, as long as submit button is not used.

The PowerBox will not memorize the change until Memorization is set to 1 and submit button activated. If one has to change the IP address, do not forget to memorize the new IP affectation otherwise the PowerBox will be lost in the Ethernet network. In case of such problem, the operator may use the MAC address to recognize the PowerBox by sniffing the Ethernet network or simply connect to the serial link RS232 under Modbus-RTU serial protocol in order to reconfigure the PowerBox or apply a Factory Settings in the worst case.

The MAC address also stands for the serial number of the device.


PowerBox 26/07/2020 81229466B

4.5.4. Power Control Parameters

o MODE (@200): Very important! Specify the operating Mode of the PowerBox (change, memorize once for all and reset the PowerBox before any heating operation):

• 0 No heating.

• 1 M1P8 Monophased Mains and 8 mono-loads on group A.

• 2 M1P16 Mode Monophased Mains and 8 mono-loads on A & B.

• 3 M1P24 Monophased Mains and 8 loads on A, B & C.

• 5 M3P+N Triphased Mains + Neutral and 24 mono-loads on A, B & C.

• 6 M3P Triphased Mains and 24 mono-loads on A, B & C.





Caution! All other values are considered as No Heating Modes (= 0).


PowerBox 26/07/2020 81229466B

o RTYP (@800): Very important! This register stands for all loads’ internal model which impacts current, power and ohmic value calculations:

• 0: Constant resistive loads. Whatever the Setpoint and operating conditions, this load’s ohmic value will vary less than 10% or 20% during its whole working life.

• 1: infrared resistive loads. According to the Setpoint and the operating conditions (Temperature of the furnace etc.), this load’s ohmic value may vary very strongly up to 10 times at cold start-up.

If RTYP is wrong, Auto-Calibration will never end correctly and all detections from partial load failure to overcurrent will behave strangely. RTYP must always be checked before launching Auto-Calibration sequence or heating regulation process.

o REGUL (@650): Very important! This register specifies which regulation mode is used to control heating process:

• 0: Conduction Rate (default mode): the Setpoint ranges 0.0% to 100.0% as a modulation (1000 = 100%).

• 1: Active Power Regulation: the Setpoint ranges from 0 Watt to 32kW but should not exceeds the maximum power dissipated by the load at nominal point which is a physical limit. The unit used for the setpoints depends on PMUL register’s value. Power regulation takes automatically into account the load’s resistive variations.

• 2: Active Current Regulation: the Setpoint ranges from 0.0A to 3200.0A but cannot exceed the maximum current dissipated by the load which is a physical limit. Current regulation takes automatically into account the load’s resistive variations.

• 3: Rms Voltage: the Setpoint ranges from 0.0V to 3200.0V rms voltage applied on the load but cannot exceed the mains’ maximum voltage which is a physical limit. Instantaneous voltage is still similar to the mains but rms voltage is modulated according to the Setpoint. In that case, the load’s resistive variations are no longer taken into account.

o USCALE (@129): Define Mains’ voltage scale to calibrate this measure. Default

value equals 1785 with the 24V 25VA transformer delivered with the Powerbox.


PowerBox 26/07/2020 81229466B

o ERRPLF (@875): this register concerns Partial Load Failure detection such as TPLF register.

• ERRPLF’s default value is 100 = 10.0%.

• This is the PLF threshold.

• When a load’s ohmic error exceeds this threshold during a period that

exceeds TPLF timer, an alarm is displayed.

o TPLF (@257): Enter partial load failure timer (see ERRPLF). TPLF’s default value is 15s.

o TRCC, IRCC (@280, 281): Define short circuit detection behaviour thanks to its two parameters:

• IRCC is the detection’s threshold in 0.1A.

• TRCC is the detection’s timer: 100 = 100x10ms = 1s.

• When there is no static relay delivering current to its load, a short circuit error will happen if the PowerBox measures a current which is greater than this threshold during a period which exceeds the detection’s timer TRCC.

• IRCC’s default value is 500 = 50.0 A.

• TRCC’s default value is 10000 = 10s.

• When IRCC is 0, the detection is disabled.

o PROFIBUSID (@99): Identifier for Profibus-DP from 2 to 99.


PowerBox 26/07/2020 81229466B

4.5.5. Multi zones Parameters

o IAMODE, IBMODE, ICMODE (@102, 104, 106): Define groups A, B & C’s current

sensor model: 0 = no sensor, 1 = bipolar HAT/HTA, 2 = unipolar HASS. (See Hardware configuration chapter).

o IASCALE, IBSCALE, ICSCALE (@138, 139, 140): Specify current sensors’ scale.

Default value equals 4435 for HASS 200A current sensors.

4.5.6. Ethernet Parameters & Memorization

In order to memorize all changes, the operator must change Memorize from 0 to 1 and submit. Otherwise, after a power shut down all changes will be lost. This register gets back to 0 automatically when memorization is successful.

Parameters “IP Address” and “Mask Address” enable the operator to access the Web Server and Modbus-Ethernet industrial communication.

MAC address identifies the PowerBox on the Ethernet network and also stands for the Product code for after sales matters.
