CONSTITUTIVEELEMENTS
IMPORTANT : The informations given by this sheet must be used to order spare parts. Take care of it
Page 3
1) APPLICATION
- The AVR model R630 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 insure, 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 R630 is composed of electroniccards wich are included in a rack 19" .- Except the necessary "Generator I/O", the optional"mains I/O" located on the left of the rack and the "dri-ver " card located on the right, all the other cards canbe plugged anywhere in the rack. Future optionalcards could be added without any internal wiring modi-fication.- 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 (19 terminals, two orthree through fuses or breaker )- A command / control terminal block (41 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
- CosØ / KVAR regulation (2F)
- Voltage equalization with the mains (3F)
- Voltage and P.F digital potantiometers
- Manual operation
- Ifield digital potentiometer with follower
- 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 PMG). Single phase : Maximum180Vac 150HzThree phases : Maximum150Vac 150Hz
- Field output : 12 Amperes nominal, 24Amp maximum during 10s on 6Ω minimum
- Accuracy : +/-1% of the means of the three phases on linearload and without droop
- Voltage setting range : +/-10% 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, ceiling unlocked time too long
- Environnement : Maximum ambiant temperature -10°C à +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, from Vm (machine voltage image), Vref(voltage set point) and complementary informationsgiven in the following, elaborates the voltage commandof the power driver card, which is the field current setpoint.
- Three operating modes are possible, depending of ex-ternal informations :
• Solo operation or parallel operation between equiva-lent machines (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 betweenmachine and mains before coupling (3 Fonction)(only if "MAINS I / O" CARD is fitted)
1F : Machine image Vmis compared with the sum ofVref, Pext, etc voltages depending of used options andthe resultant voltage (error voltage ) feeds the PID.
2F : When cosØ cmd input is activated (+Vcc), themachine voltage Vm is compared to the voltage givenfrom the cosØ/KVAR card and the result (error voltage)feeds the PID.
3F : When U/U cmd input is activated (+Vcc), the ma-chine voltage Vm is compared to the voltage given fromthe "MAINS I / O" card and the result (error voltage)feeds the PID.
A compensation external input, given for specific applica-tions is added to the error voltage and the resultantvoltage is the real PID input. Each branch (P, I, D) of thePID, independently adjustable from the others, set thetime constants of the AVR in regard to the generator.The integrator branch can be short-circuited, for examplewhen 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 ofparallel operation with the mains (cosØ/KVAR card), thislimitation is a function of the active power supply by thegenerator, this information is given by the COSØ / KVARcard.A separate stage detect if the generator voltage is belowan adjustable value to unlock the normal field ceiling vol-tage from 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 point input(option)- 22c : Added signal to voltage reference set point input(external voltage option)- 21a : Added signal to voltage reference set point input(external potentiometer option) - 13a : Added signal to voltage reference set point input(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) (with cosØ/KVARcard)- 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" voltagereference and some additional informations detailed inthe following, the exciter field current supply by the regu-lator and the booster (if used).
- Three operating mode are possible, depending of ex-ternal informations :
• Normal mode with 110% ceiling of If nominal. • Ceiling unlocked mode (160% minimum Ifield nomi-
nal) depending of the command input from the PID cardwith limited delay and alarm output in case of sustainedundervoltage.
• Maximum ceiling mode if the synchronisation voltagedesappears ( machine short-circuit) with limited (adjusta-ble) field current.
- The "AUTO" or "MANU" reference voltage depending ofthe associated command input and also of the activelimitations, is compared to the field current measurementand gives the error voltage which is after integration,compared to a sawtooth feed by the synchronisation vol-tage. The output of this stage is a variable duty cyclesignal which controls the power transistors throught iso-lating optocouplors.
- This card can be supplied in three manners :• From the general supply of the rack in normal opera-
tion• Throught an isolated supply taken from the field
voltage during start-up or generator short-circuit (Racksupply not present)
• Directly from the field voltage for power transistorcommand.
The permanent limitation (110% de Iexc nominal) canbe modified by the following conditions:- Field ceiling unlocking on machine undervoltage condi-tion. It inccreases from 110% (normal operation) to aminimum of 160% of the nominal field current during anadjustable time delay and then go back to 110%. Analarm is activated if this undervoltage is sustained after-ward.- Field ceiling unlocking on synchronisation voltagecence. It increases to the maximum given by the sett-ingof P7.- Field ceiling limitation caused by power heatsink over-heating. On thermocontact action the ceiling is reducedto a value given by the setting of P8. A separate circuit monitors the instantaneous current ofthe power transistor and reduces immediatly the com-mand signal if its value increases above a fixed value.(Exciter or wiring 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 no-minal)- 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 over-heating.

1 - FUNCTIONALThis card elaborates from generator current and voltageinformations, the following signals:
- An image of the reactive current of the generatornamed (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 instanta-neous voltage reaches zero on positive slope.
- First the current image of the stator current is filteredand used directly for KVAR measure. Then it is derivated and used for KW measure. And then it is amplified toobtain square waves and integrated to give a sawtoothused to Ø measure.
- The voltage image is phase-shifted to compensate thephase shift of the current input filter and after amplifica-tion is fed to a monostable which gives the pulse signal(about 100µs) 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 tothe PID card as an error signal. An external contactcontrol an analog switch to select what information bet-ween KVAR and Ø 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 moreding 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 decrea-ses if more KVAR (lagging) and opposite if less.CAV3 : No droop for PF setting (P2), voltage decreasesif more lagging and opposite if less or leading.
Nota : If the droop is used from this card, potentiometerP1 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 switchween P.F and KVAR setting is made by the external or-der (terminals 48,53)
- Each last position is memorized when the control isswitched or when the machine is stopped.
- Jumps (SW1 and SW2) allow the choice betweenunipolar or bipolar voltage output and the range is adjustedby means of potentiometers P02 and P03.
- Jumps SW3 and SW4 must be open for normal opera-tion and are only used for special applications.
- Speed of all adjustments is controled by potentiometerP01.
- Two LED's (L1,L2) indicate the command orders + or -and four other LED's (L3,L4 and L5,L6) indicates themaximum and minimum position of voltage and P.Fsettings
NOTE : When this card fitted, the internal voltagesetting (P05 on sensing card) must be used to givethe center position of the range (if bipolar range) orthe minimum setting in case of unipolar range (idemfor P.F and Kvar internal setting on P.F card). Anexternal setting potentiometer must not be used, thesettings are made only by mean of push-buttons onterminals 42, 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 +/-)

1 - FUNCTIONALThis card elaborates from internal setting (PO2) andexternal setting informations, the Ifield command signalgiven to "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 thepotentiometer P01 (trip of the main breaker on load forexample).
- 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 compensationsignal which is used to compensate the PID to havealways the MANU and AUTO channels outputs identical.With this circuit a smooth switching between MANU toAUTO is possible and operation will go back to theAUTO channel own settings.
- The ceiling can be unlocked on this operation, that iswhy it can be necessary to wait some seconds after theswitching to return on MANU operation.
- On AUTO operation, these two channels are also moni-tored 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 identical and smooth AUTO ---> MANU switching is possible.
NOTE : If a Ifield digital potentiometer is used, theinternal setting (P02) must be set to 0 or under theno load field value and an external setting potentio-meter must not be used. In that case the setting ismade only by mean of push-buttons on terminals 44,45, 46.

card
1 - FUNCTIONALThis card replace one conventional motorized potentio-meter in "MANU" mode and sets the "MANU" channeloutput always equal to the "AUTO" one to allow thesmooth switching between the "AUTO" and "MANU"ration at any load (follower in "AUTO" mode).
- Switch between the two modes is made by the external"AUTO / MANU" order (terminals 47,48)
- Jumps SW1 allows the choice between voltage outputtaken from U/F control of the sensing card or from a 5Vfixed reference and the range is adjusted by means ofpotentiometer P03.
- Jumps SW3 and SW4 must be open for normal opera-tion and closed for follower operation.
- Speed of the adjustment is controled by potentiometerP01 in manual setting and by P02 in follower operation.P02 acts as a delay between an "AUTO" output variationand the "MANU" output response.
- Two LED's (L1,L2) indicate the command orders + or -and two other LED's (L3,L4) indicates the maximum andminimum position of Ifield settings
NOTE : When this card is fitted, the internal Ifieldsetting (P02 of manual mode card) must be set to 0or under the no load field value and an externalsetting potentiometer must not be used. The Ifieldsetting is made only by mean of push-buttons onterminals 44, 45, 46.
2) ADJUSTMENTS- P1 : Clock speed (Time delay in follower mode) - P2 : Clock speed (range time in "MANU" mode)- P3 : Ifield range value- SW1 : Voltage range fixed or U/F monitored - SW3/4 : Normal (open) or follower (closed) operation
3 - INPUTS / OUTPUTSFlat cable (BUS 64points)- 23c : Cmd lower - 22a : Cmd upper- 25a : Cmd "AUTO / MANU"- 11a : U/F voltage reference- 16c : If reference set point input - 15a : If reference set point input "MANU" channel- 27c : Ifield setting output to Manual mode card - 30a : Maximum position of settings- 1a,1c : +15Vdc regulated (Vcc)- 32a,32c : -15Vdc regulated (Vdd)- 16a,17c : Common ground (GND or 0V)

1 - DESCRIPTIONThis card is used when the P.F or KVAR regulation iswanted not at the generator terminals but at the mainsinput. For this a P.F or KVAR sensor with 4-20mA outputis necessary and it must be located at the place wherethe regulation must be made.
2 - FONCTIONALThis card elaborates from setting informations and 4-20mA signal image of P.F (or KVAR) of the mains, theerrorvoltage dending to the PID of the PID card.
- The error signal have an ajustable gain and can beversed 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 contactbetween terminals 33, 34 of main terminals will be closed.If the contact on front connector remains open, the regu-lation (P.For KVAR) will be made at the generator out-if it is closed, this is the 4-20mA information wich is regu-late function of the internal settings (P2 or channel 2 4-20mA) or/and external by the front connector.
- If during operation, the measuring 4-20mA signaldeseappears, control is automatically return to regulationon the generator output side and this failure is indicatedby LED 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 orKVAR on generator side. As on channel 1 if the 4-20mAdeseappears, output is inhibited and indicated by LEDL2.
- A field current limitation is given, active when a contact(front connector) is closed and indicated by LED L4. Thelimitatio is adjusted by P7 (Limit 2 set) and can be setbetween a maximum value preset by P7 on driver cardand a minimum 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 digi-tal potentiometers 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 signalves a voltage correction which is added to the main PIDinput to maintain the stator current equal to the adjus-ted 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 sourceduring the start operation and can be switched on thenerator output when the voltage have reached the no-minal value. The switching must be as fast as possible(by relay, not by 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, when a manual mode card was requiredand plugged inside the AVR, the best is to use the manualmode for testing the sensing wires between the generatorand the AVR.
- For this it is necessary to have a manual mode card plug-ged in the AVR. If not, see directly §2.
- Short-circuit terminals 47and 48 (AVR terminal block).
- 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 25 and 26 of theAVR terminal block is about one volt.
- If yes, remove the strap between terminals 47 and 48 ofAVR terminal block.
- 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 PMG (terminals 17,18 and19 of AVR). Check also the fuse (or breaker) on the terminal17,18,19 of AVR terminal block.
- If the voltage is too hight, check that the auxiliary voltageat the terminals 15 and 16 of AVR and 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 must be used.
- E01 must be serie with PMG outputs (AVR power in-puts) and are opened 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.
-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- Permanent Magnet Generator does not need a fieldflashing.
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)

CAUTION
Never energize the AVR when the driver card isremoved. An overvoltage can appear and the po-
wer transistor can be damaged.
7) PARALLEL WITH THE MAINS (2F)- The generator and mains voltages must be as equal aspossible. (see §8 if MAIN I/O card is used). The contact bet-ween terminals 33, 34 of AVR terminal block must be clo-sed at the same time as the coupling and will remain clo-sed as long as the generator is connected to the mains. 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 0.8 . 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 (27,28,29)
- If the KVAR regulation is required terminals 48 and 53must 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 (30,31,32)
-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 terminals12,13,14 of the AVR terminal block.- Short circuit terminals 35,36 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 35,36 of the AVR ter-minal block. - The initial setting is made.
In normal operation the contact between terminals 35,36of 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.
- Short-circuit the terminals 47,48 of the AVR terminal blockgives control to the manual channel and the field current isadjusted by potentiometer P2 and/or by an external option-nal potentiometer (10KΩ-1W) connected to the terminals30,52,23 of the AVR terminal block cursor on 52 and hotpoint on 30.
- 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 fast 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. LED"LIMIT" on front of the card will light. The setting of fieldcurrent must be reset manually to the no load value andthe LED "LIMIT" will switch off.
