= Necessary

= Optionnal

IMPORTANT : The informations given on this sheet will be used to order spare parts. Take care of it.

1) APPLICATION

- The AVR model R600 can be used with brusless self-excited type generators, "SHUNT", "SHUNT withBOOSTER" or "SHUNT with PMG" excitation. In caseof "SHUNT with BOOSTER the booster current is total-ly monitored by the AVR.- The AVR is able to ensure, depending of its constitu-tion, solo operation, parallel operation between equiva-lent generators or parallel operation with the mainswith cosØ or KVAR regulation.

2) DESCRIPTION

- The AVR model R610 is composed of electroniccards wich are included in a half rack 19" .- An empty slot located on the left of the rack allowsfuture optional cards to be added without any internalwiring modification.- The rear flat cable (BUS 64 points) is given morelong as it can be connected to an optional interface ter-minal block wich gives all the internal test points or inthe future the possibility to connect another rack if thecards number will become too important.

3) INTERCONNECTIONS

- External interconnections are located on the top ofthe rack in form of two terminal blocks:- A power / voltage terminal block (16 terminals, twowith fuses )- A command / control terminal block (24 terminals)- A conventional wiring connect this terminal blocks tothe power block fitted on a heatsink and also to the"generator I/O" and "mains I/O" to give an interfacewith the flat cable BUS 64 points.- In the same manner a 8 points connector connectsdirectly the driver card to the power block.

4) OPTIONAL CARDS

- Basically the AVR allows voltage regulation withreactive sharing when paralleling with other machines.

The following cards can be plugged into the AVR wi-thout internal wiring modification :

- CosØ / KVAR regulation (2F) (// with the mains)

- Voltage equalization with the mains (3F) (Synchro)

Only one is possible with the following cards

- Voltage and P.F digital potantiometers

- Manual operation

- Istator limitation

- Mains P.F or KVAR regulation from 4-20mA sensor

5) SPECIFICATIONS :

- Sensing voltage : 100/110Vac 50Hz : 120/130Vac 60Hz : 380/420Vac 50Hz : 430/450Vac 60Hz

- Power supply : Depend of generator(Adaptation by transformer).Maximum 180Vac 50/60Hz: PMG possible maximum 150Vac 3Ø 50/150Hz

- Field output : 8 Amperes nominal, 20Amp maximum during 10s on 6Ω minimum

- Accuracy : +/-1% of the means of the three phases on linearload and without droop

- Voltage setting range : +/-5% of the nominal voltage by means of external optionnal potentiometer .

- Droop setting range: - 7% of the nominal voltage at cosØ =0

- Under-frequency protection : Adjustable threshold and slope from V/Hz to 2V/Hz

- Field ceiling : 110% of If nominal permanently, unlockedin case of voltage decrease

- Protection: Heatsink overheating, exciter short-circuit

- Alarm output: Heatsink overheating, too much ceiling unlockedtime

- Environnement : Maximum ambiant temperature -10°C to +50°C: Fitting in control panel without excessive vibra-tions

6) SCHEMATICS AND DRAWINGS

- Following schematics give all the usual informa-tions on the interconnexions between the terminal block,the I/O connectors and the power block.

1) FUNCTIONAL- This card elaborates from the three phases voltage

image of the generator given by the "ALTERNATOR I/O" :-A rectified, calibrated, filtered voltage Vm proportional to

the stator voltage of the generator. Vm could be affected bydroop depending of adjustment.

- A voltage function of the generator frequency, a part ofwhich gives the reference set point named Vref.

- Vref is a constant above the underfrequency thresholdset point (signaled by LED) and decreases below this thres-hold following a function depending of the position of thestrap CV1:

- In fixed V/Hz mode-In adjustable kVolt / Hz (see curve below)

1) FUNCTIONAL- This card, from Vm (machine voltage image), Vref (vol-

tage set point) and complementary informations given in thefollowing, elaborates the voltage command of the power dri-ver card, which is the field current set point.

- Three operating modes are possible, depending of ex-ternal informations :

- Solo operation or parallel operation between equivalentmachines (1 Fonction)

( This is the normal mode)

- Parallel operation with the mains with power factor(COSØ) or KVAR regulation (2 Fonction)

( Only if COSØ / KVAR card is fitted)

- Operation in voltage equalization mode between ma-chine and mains before coupling (3 Fonction)

( Only if "MAINS I / O" CARD is fitted)

1F : Machine image Vmis compared with the sum of Vref, Pext, etc voltages depending of used options and theresultant voltage (error voltage ) feeds the PID.

2F : When cosØ cmd input is activated (+Vcc), the ma-chine voltage Vm is compared to the voltage given from thecosØ/KVAR card and the result (error voltage ) feeds thePID.

3F : When U/U cmd input is activated (+Vcc), the machi-ne voltage Vm is compared to the voltage given from the"MAINS I / O" card and the result (error voltage ) feeds thePID.

A compensation external input, given for specific applica-tions is added to the error voltage and the resultant voltageis the real PID input. Each branch (P, I, D) of the PID, inde-pendently adjustable from the others, set the time constantsof the AVR in regard to the generator. The integrator branchcan be short-circuited, for example when starting-up.

These three outputs are added, limited to 10Vdc andthen give the field current set voltage of the "automaticchannel" which is the driver card input.

The minimum value of this signal can be limitated toavoid total loss of excitation of the generator. In case of pa-rallel operation with the mains (cosØ/KVAR card), this limi-tation is a function of the active power supply by the genera-tor, this information is given by the COSØ / KVAR card.

A separate stage detect if the generator voltage is belowan adjustable value to unlock the normal field ceiling voltagefrom 110% of nominal to 160% (adjustable).

2) ADJUSTMENTS- P1 : Ceiling unlocked voltage threshold adjust (nor-mally 90% Un).- P2 : Proportionnal branch gain adjust (large signal)- P3 : Proportionnal branch gain adjust - P4: Integrative branch time constant adjust- P5 : Derivative branch gain adjust- P6 : Derivative branch time constant adjust- P7 : Minimum field limitation adjust- P8 : Minimum field limitation, active power correctionadjust

3) INPUTS / OUTPUTS

- 11a : Voltage reference set point input. Vref- 13c : Added signal to voltage reference set pointinput (option )

- 22c : Added signal to voltage reference set pointinput (external voltage option )- 21a : Added signal to voltage reference set pointinput (external potentiometer option ) - 13a : Added signal to voltage reference set pointinput (differential droop option; with cosØ/KVAR card ) - 19a : Integrator short-circuit command input- 10a : Mains image voltage input (3F) ( with"MAINS I / O" card only)- 14c : CosØ error voltage input (2F) (withcosØ/KVAR card )- 25c : Voltage equalization command input (3F)(with "MAINS I / O" card only)- 24a : CosØ regulation command input (2F) ( withcosØ/KVAR card )- 1a,1c : +15Vdc regulated (Vcc)- 32a,32c: -15Vdc regulated (Vdd)- 16a,17c: Common electronic ground- 14a : Minimum field limitation, active power correc-tion input - 15c : Field current voltage control output "AUTO"channel

1) FUNCTIONALThis card controls from "AUTO" and "MANU" voltage re-

ference and some additional informations detailed in the fol-lowing, the exciter field current supply by the regulator andthe booster (if used).- Three operating mode are possible, depending of externalinformations :

- Normal mode with 110% ceiling of If nominal. - Ceiling unlocked mode (160% minimum Ifield nominal)

depending of the command input from the PID card with li-mited delay and alarm output in case of sustained undervol-tage.

- Maximum ceiling mode if the synchronisation voltagedesappears ( machine short-circuit) with limited (adjustable)field current.

- The "AUTO" or "MANU" reference voltage depending ofthe associated command input and also of the active limita-tions, is compared to the field current measurement and gi-ves the error voltage which is after integration, compared toa sawtooth feed by the synchronisation voltage. The outputof this stage is a variable duty cycle signal which controlsthe power transistors throught isolating optocouplors.

- This card can be supplied in three manners :

- From the general supply of the rack in normal operation- Throught an isolated supply taken from the field voltage

during start-up or generator short-circuit. (Rack supply notpresent)

- Directly from the field voltage for power transistor com-mand.

The permanent limitation (110% de Iexc nominal) can bemodified by the following conditions:

- Field ceiling unlocking on machine undervoltage condi-tion. It inccreases from 110% (normal operation) to a mini-mum of 160% of the nominal field current during an adjusta-ble time delay and then go back to 110%. An alarm is acti-vated if this undervoltage is sustained afterward.

- Field ceiling unlocking on synchronisation voltage ab-cence. It increases to the maximum given by the setting ofP7.

-Field ceiling limitation caused by power heatsink over-heating. On thermocontact action the ceiling is reduced to avalue given by the setting of P8. A separate circuit monitors the instantaneous current of thepower transistor and reduces immediatly the command si-gnal if its value increases above a fixed value. (Exciter orwiring short-circuit protection ).

2) ADJUSTMENTS- P1 : Integrator time constant adjust.- P2 : Unlocked ceiling time delay adjust. (generally

5s)- P3 : Alarm time delay adjust after ceiling unlock.- P4 : Permanent ceiling value adjust (generally

1,1If nominal)- P5 : HALL sensor range adjust.- P6 : Initial ramp-up adjust- P7 : Maximum field current adjust (machine short-

circuit )- P8 : Maximum fieeld current in case of heatsink

overheating.

1) FUNCTIONALThis option allows the parallel operation coupling with the

mains with P.F or KVAR regulation (also called 2F)

This card elaborates from generator current and voltageinformations, the following signals:

- An image of the reactive current of the generator na-med (KVAR) used for KVAR regulation.

- An image of the phase shift between the voltage andthe current of the generator named (Ø) used for cosØ (PF)regulation.

- An image of the active current of the generator named(KW) used for compensate the minimum Ifield limit of thePID card.

- The principle of measurement is to sample and hold theinstantaneous value of the current when the instantaneousvoltage reaches zero on positive slope.

- First the current image of the stator current is filteredand used directly for KVAR measure. Then it is derivatedand used for KW measure. And then it is amplified to obtainsquare waves and integrated to give a sawtooth used to Ømeasure.

- The voltage image is phase-shifted to compensate thephase shift of the current input filter and after amplification isfed to a monostable which gives the pulse signal (about100µs) used by all the sample and hold circuits.

- KVAR and Ø values are compared with an internal andexternal (if used) setting and the difference is send to thePID card as an error signal. An external contact control ananalog switch to select what information between KVAR andØ will be regulated.

- Three informations (Ø, ∆Ø, ∆KVAR) can be used as analternative droop for solo operation.

- Ø gives no droop at cosØ=1 and the voltage decreasesat lagging PF.

- ∆Ø gives no droop at the cosØ setting and the voltagedecreases at more lagging PF and opposite for more lea-ding PF.

- ∆KVAR gives no droop at the KVAR value setting andthe voltage decreases with more KVAR and increases ifless.

- The selection between these is made by mean of jum-per (CAV) on the card. (internal)

2) ADJUSTMENTS- P1 : KVAR internal setting.- P2 : PF (cosØ) internal setting.- P3 : Voltage phase shifter (internal)- P4 : PF (cosØ) gain setting - P5 : KVAR gain setting.- P6 : Différential droop setting- P7 : Pulse width setting (internal)

- Jumper CAV : Selection of droop type

No : Reactive droop adjusted by P1 (sensing card)CAV1 : No droop for cosØ=1 and droop if lagging.CAV2 : No droop for KVAR setting (P1), voltage de-

creases if more KVAR (lagging) and opposite if less.CAV3 : No droop for PF setting (P2), voltage de-

creases if more lagging and opposite if less or leading.

Nota : If the droop is used from this card, potentio-meter P1 of the sensing card must be set to zero.

1) FUNCTIONALThis card replace two conventional motorized potentio-

meters: - One for the remote voltage setting.- One for power factor or reactive current setting.

- Switch between the two modes is made by the externalP.F regulation order (terminals 33,34) and switch betweenP.F and KVAR setting is made by the external order (termi-nals 48,53) - Each last position is memorized when the control is swit-ched or when the machine is stopped.

- Jumps (SW1 and SW2) allow the choice between unipolaror bipolar voltage output and the range is adjusted bymeans of potentiometers P02 and P03.

- Jumps SW3 and SW4 must be open for normal operationand are only used for special applications.

- Speed of all adjustments is controled by potentiometerP01.

- Two LED's (L1,L2) indicate the command orders + or - andfour other LED's (L3,L4 and L5,L6) indicates the maximumand minimum position of voltage and P.F settings

-NOTE: When this card fitted, the internal voltage set-ting (P05 on sensing card) must be used to give thecenter position of the range (if bipolar range) or the mi-nimum setting in case of unipolar range (idem for P.Fand Kvar internal setting on P.F card). An external set-ting potentiometer must not be used , the settings aremade only by mean of push-buttons on terminals42,43,44.

2) ADJUSTMENTS- P1 : Clock speed (total range time) - P2 : Voltage range value- P3 : P.F or KVAR range value- SW1 : Voltage range polarity (0/+ or +/-)- SW2 : P.F or KVAR range polarity (0/+ or +/-)


- 24c : Cmd lower - 23a : Cmd upper- 16c : If reference set point input - 15c : If reference set point input "AUTO" channel- 24a : External P.F regulation order- 20a : External P.F or KVAR regulation order- 13c : Voltage setting output to PID card - 20c,21c: P.F or KVAR setting output to P.F card - 30a : Maximum position of settings- 1a,1c : +15Vdc regulated (Vcc)- 32a,32c: -15Vdc regulated (Vdd)- 16a,17c: Common ground (GND or 0V)

1) FUNCTIONALThis card elaborates from internal setting (PO2) and ex-

ternal setting informations, the Ifield command signal givento "MANU" channel of the driver card.

- The Ifield output signal is limited or reduced if the gene-rator voltage exceeds the limitation value sets by the poten-tiometer P01 (trip of the main breaker on load for example ).

- This case of operation is indicated by the LED "LIMIT"and the Ifield setting must be decreased to a point undercontrol.

- On MANU operation, the difference between MANUoutput and AUTO channel output gives a compensation si-gnal which is used to compensate the PID to have alwaysthe MANU and AUTO channels outputs identical. With thiscircuit a smooth switching between MANU to AUTO is pos-sible and operation will go back to the AUTO channel ownsettings. - The ceiling can be unlocked on this operation, that is whyit can be necessary to wait some seconds after the swit-ching to return on MANU operation.

- On AUTO operation, these two channels are also monito-red and the difference is indicated by three LEDs.

- HIGH says that MANU channel is higher than AUTO- LOW says that MANU channel is lower than AUTO

- OK says that MANU and AUTO channels are identicaland smooth AUTO ---> MANU switching is possible.

NOTE :

For the R610, the switching between AUTO <--> MANU isonly possible by the switch command in front of the card,and the setting by the front potentiometer. It is not possibleto use remote command or control.

1) DESCRIPTIONThis card is used when the P.F or KVAR regulation is

wanted not at the generator terminals but at the mains input.For this a P.F or KVAR sensor with 4-20mA output is neces-sary and it must be located at the place where the regula-tion must be made.

2) FONCTIONALThis card elaborates from setting informations and 4-

20mA signal image of P.F (or KVAR) of the mains, the error-voltage dending to the PID of the PID card.

- The error signal have an ajustable gain and can be in-versed depending of the 4-20mA sensor output.

- This kind of operation is indicated by the LED "L3" andby a contact (potential free) on the front connector.

- This operation is selected by mean of a contact on frontconnectort and will be active on coupling when contact bet-ween terminals 33,34 of main terminals will be closed. If thecontact on front connector remains open, the regulation(P.For KVAR) will be made at the generator output, if it isclosed, this is the 4-20mA information wich is regulate func-tion of the internal settings (P2 or channel 2 4-20mA)or/and external by the front connector.

-If during operation, the measuring 4-20mA signal de-seappears, control is automatically return to regulation onthe generator output side and this failure is indicated byLED L1 ou L2 and by a contact on front connector .

- A second channel can be used as set point of the firstchannel or as a remote adjustment of voltage, P.F or KVARon generator side. As on channel 1 if the 4-20mA deseap-pears, output is inhibited and indicated by LED L2.

- A field current limitation is given, active when a contact(front connector) is closed and indicated by LED L4. The li-mitatio is adjusted by P7 (Limit 2 set) and can be set bet-ween a maximum value preset by P7 on driver card and aminimum value preset by P8 on driver card.

- An signaling contact on the front connector gives (ifthey are used) the indication that one or more of the digitalpotentiometers are at maximum position .

1) FUNCTIONAL- A voltage, image of the stator current of the machine,

fed from the "ALTERNATOR I / O" card is rectified, filteredand compared to a reference voltage. The error signal givesa voltage correction which is added to the main PID input tomaintain the stator current equal to the adjusted value.

- The reference voltage is applied with an initial rampajustable from 0,5 to about 4s.

- A front LED signals stator current limitation operation.

- When this card is used for soft-start operation, the AVRpower transformer must be fed from a separate source du-ring the start operation and can be switched on the genera-tor output when the voltage have reached the nominal va-lue. The switching must be as fast as possible (by relay , notby manual switch)

2) REGLAGES- P1 : Stator current limit adjust. (about 2In to 4In )- P2 : Ramp-up time adjust. (0,5 à 4s environ)- P3 : Output signal gain

3) INPUTS /OUTPUTS- 9a : Stator current image input (1Vac for In)- 1a,1c : +15Vdc regulated (Vcc)- 32a,32c : -15Vdc regulated (Vdd)- 16a,17c : Common ground (GND or 0V)- 12c : Voltage correction output to PID.

1) STARTING WITH MANUAL MODE CARD- For initial start-up, the best is to use the manual mode fortesting the sensing wires between the generator and theAVR.

- For this it is necessary to have a manual mode card plug-ged in the AVR. If not, see directly §2.

- Switch the manual card on ON (switch in front of card).

- Set the potentiometer P2 on manual card maximum CCW,start the prime mover up to the nominal speed.

- Turn slowly the potentiometer CW to obtain the nominalvoltage.

- Check the presence and the value of the three phases atthe AVR terminal block ( terminals 1, 2, 3 )

- Set the voltage to 5% above the nominal voltage.

- Check that the voltage between terminal 39 and 20 of theAVR terminal block is about one volt.

- If yes, switch off the manual operation in the front of ma-nual card.

- The voltage must reach the nominal value.

- Go to §3

2) STARTING WITHOUT MANUAL MODE CARD- start the prime mover up to the nominal speed..

- If the voltage does not appear, check wires between AVRand the generator field (terminals 5 and 6 of AVR),and thealso the wires between AVR and power transformer (termi-nals 14,15 (and 16 if used) of AVR. Check also the fuse in-side the terminal 14,16 of AVR terminal block.

- If the voltage is too hight, check that the sensing voltagesat the terminals 1, 2, 3 of the AVR terminal block are pre-sent.

- Adjust the nominal voltage with Vref (P5) of the sensingcard for the middle position of the external voltage potentio-meter (if used).

3) DE-ENERGIZING (optional)- External contacts E01 and E02 must be used.

- E01 must be serie with terminal 14,15 of AVR (powerinput) and is opened for de-energizing.

- E02 must short-circuit the booster output (if used) (ter-minals 7 and 8 of AVR) and is closed for de-energizing.

4) ADJUSTMENTS- Refer also to card descriptions.

- The AVR is normally preset in factory.

- The nominal voltage can be set by Vref (P5) on sen-sing card. Fine adjustment can be made by an externalvoltage potentiometer (10KΩ), (terminals 21,22,23)

-If an adjustment must be moved, note carefully theoriginal setting for resetting in case of problems.

- If the strap V/Hz of sensing card is on kV/Hz position,the original setting is V/Hz and can be changed bet-ween V/Hz and 2V/Hz by potentiometer P4.

-The stability is adjusted with the machine in factory . Ifnecessary, the response time can be changed by thesetting of potentiometer P4 of PID card.

- Other settings are difficult to adjust without specificelectronics equipments. It is better to not change them.

5) FIELD FLASHING- Generally, field flashing is not necessary, but in somecases like long stop time or fault trip, it can be possiblethat the voltage does not appear naturally. In this case, connect a 12Vdc to 24Vdc voltage sourceto the terminals 4 and 8 of AVR terminal block, + to 4for a short time and remove it when the voltage increa-ses.

6) PARALLEL OPERATION(1F)- The generator voltages must be as equal as possible.

- Same for the droop. If it is not possible to measure it,set the potentiometers P1 of the sensing cards all in thesame position. (middle set for example). If the droop setting is made from cosØ/KVAR card(when used), see notice NT 1950080.

- The reactive currents (KVAR) must be shared, imme-diatly after coupling, even the KW are not shared.

- If, immediatly after coupling, the current increases ab-normally, check if the parallel CT wires are not rever-sed. ( 9 et 10 of AVR terminal block)

- If the coupling is OK but if when the load increases,the cosØ or the current have an abnormal value, checkthat the sensing phases at the input of the AVR areright connected. (U, V, W respectively to the terminals1, 2, 3 if clockwise rotation or W, V, U, if counter clock-wise rotation)

AVRMODEL R610

START-UP

NT1959255/a-03/96 f:1/2

CAUTION

Never energize the AVR when the driver card is re-moved. An overvoltage can appear and the power

transistor can be damaged

Page : 41/43

7) PARALLEL WITH THE MAINS (2F)- The generator and mains voltages must be as equal aspossible. (see GENERATOR/ MAIN I/O card manual). Thecontact between terminals 30, 31 of AVR terminal blockmust be closed at the same time as the coupling and willremain closed as long as the generator is connected to themains. It will be open when parallel between generators.

- If, immediatly after coupling, the current increases abnor-mally, check if the parallel CT wires are not reversed. ( 9 et10 of AVR terminal block)- If the coupling is OK but if when the load increases, thecosØ or the current have an abnormal value, check that thesensing phases at the input of the AVR are right connected.(U, V, W respectively to the terminals 1, 2, 3 if clockwise ro-tation or W, V, U, if counter clockwise rotation)

- The PF value is normally factory set to 0.9 . It can be ad-just by mean of potentiometer P2 on cosØ/KVAR card or bymean of an external potentiometer (10KΩ-1W) connected toAVR terminal block (24,25,26)

- If the KVAR regulation is required terminals 37 and 38must be short-circuited and the KVAR can be set by meanof potentiometer P1 on cosØ/KVAR card or by mean of anexternal potentiometer (10KΩ-1W) connected to AVR termi-nal block (27,28,29)

-For droop setting, see notice NT 1950080.

8) VOLTAGE EQUALISATION (3F)- The following procedure must be made one time to takeaccount of the mains transformer primary/secondary ratio.- At no load and mains voltage present at terminals11,12,13 of the AVR terminal block.- Short circuit terminals 31,32 of the AVR terminal block- Adjust P1 of MAIN I/O card to have generator and mainsvoltage as equal as possible.- Remove the strap between terminals 31,32 of the AVR ter-minal block. - The initial setting is made.

In normal operation the contact between terminals 31,32of the AVR terminal block must be closed with synchronizeroperation and can be opened after coupling.

9) MANUAL OPERATION (if used)-If a manual mode card is used, it is possible to control di-rectly the field current of the generator.

- In automatic mode, adjust the potentiometer P2 on manualmode card to have the LEDs "HIGHT" and "LOW" off andthe LED OK ligthing. At this time the manual setting is equalto the automatic channel control.

- Switch on front of manual card on position "ON" givescontrol to the manual channel and the field current is adjus-ted by potentiometer P2.

- This mode can be used when initial start-up of the ge-nerator, to make test after problems or when operatingwith the mains. It cannot be used when solo operationbecause it is not possible to follow the load variations.

- When coupling with the mains on load, if trip of the ge-nerator occurs, an overvoltage may occurs due to thefact that the field current setting is too hight regardingthe load of the generator. On this case, an internal cir-cuit of the card decreases the field current to limit theovervoltage approximatively to 110% of nominal, thevoltage in this case can be unstable but protect fasterthe equipments. LED "LIMIT" on front of the card willlight. The setting of field current must be reset manuallyto the no load value and the LED "LIMIT" will switch off.
