1 - APPLICATION
5 - SPECIFICATIONS
- The AVR model R600 can be used with brusless selfexcited type generators, "SHUNT", "SHUNT with BOOSTER" or "SHUNT with PMG" excitation. In case of
"SHUNT with BOOSTER the booster current is totally
monitored by the AVR.
- Sensing voltage :
• 100/110Vac 50Hz
• 120/130Vac 60Hz
• 380/420Vac 50Hz
• 430/450Vac 60Hz
- The AVR is able to ensure, depending of its constitution, solo operation, parallel operation between equivalent generators or parallel operation with the mains with
cosØ or KVAR regulation.
- Power supply :
• Depend of generator(Adaptation by transformer).
Maximum 180Vac 50/60Hz
2 - DESCRIPTION
- The AVR model R631 is composed of electronic cards
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 "driver"
card located on the right, all the other cards can be plugged anywhere in the rack. Future optional cards could be
added without any internal wiring modification.
- The rear flat cable (BUS 64 points) is given more long
as it can be connected to an optional interface terminal
block wich gives all the internal test points or in the
future the possibility to connect another rack if the cards
number will become too important.
3 - INTERCONNECTIONS
- External interconnections are located on the top of the
rack in form of two terminal blocks:
- A power / voltage terminal block (19 terminals, one with
a fuse )
- A command / control terminal block (41 terminals)
- A conventional wiring connect this terminal blocks to
the power block fitted on a heatsink and also to the
"generator I/O" and "mains I/O" to give an interface with
the flat cable BUS 64 points.
- In the same manner a 8 points connector connects
directly 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
- Rotating diodes fault monitor
NT1950000/c-02/95 f:1/8
4
- Field output :
• 12 Amperes nominal, 24Amp maximum during 10s on
6Ω minimum
- Accuracy :
• +/-1% of the means of the three phases on linear load
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, unlocked in case of
voltage decrease
- Protection :
• Heatsink overheating, exciter short-circuit
- Alarm output :
• Heatsink overheating, too much ceiling unlocked time
- Environnement :
• Maximum ambiant temperature -10°C to +50°C
• Fitting in control panel without excessive vibrations
6 - SCHEMATICS AND DRAWINGS
Following schematics give all the usual informations on
the interconnexions between the terminal block, the I/O
connectors and the power block.

card
1 - FUNCTIONAL
2 - ADJUSTMENTS
- 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 by droop depending of adjustment.
- A voltage function of the generator frequency, a part of
which gives the reference set point named Vref.
- Vref is a constant above the underfrequency threshold
set point (signaled by LED) and decreases below this
threshold following a function depending of the position
of the strap CV1:
• In fixed V/Hz mode
• In adjustable kVolt / Hz (see curve below)
- P1 : Reactive droop adjust for parallel operation between equivalent machine.
- P2 : Vm adjust for nominal voltage. (9Vdc at Un)
- P3 : Underfrequency threshold adjust (normally Fn 5%) signaled by LED.
- P4 : Underfrequency slope adjust ( k ) in kVolt / Hz mode
(1≤ k ≤2)

card
1 - FUNCTIONAL
2 - ADJUSTMENTS
- This card, from Vm (machine voltage image), Vref
(voltage set point) and complementary informations
given in the following, elaborates the voltage command
of the power driver card, which is the field current set
point.
- P1 : Ceiling unlocked voltage threshold adjust (normally 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 correction
adjust
- Three operating modes are possible, depending of external informations :
• Solo operation or parallel operation between equivalent machines (1 Fonction)
(this is the normal mode)
3 - INPUTS / OUTPUTS
• 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
machine 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
the resultant voltage (error voltage ) feeds the PID.
2F : When cosØ cmd input is activated (+Vcc), the
machine voltage Vm is compared to the voltage given
from the cosØ/KVAR card and the result (error voltage)
feeds the PID.
3F : When U/U cmd input is activated (+Vcc), the machine voltage Vm is compared to the voltage given from
the "MAINS I / O" card and the result (error voltage)
feeds the PID.
A compensation external input, given for specific applications is added to the error voltage and the resultant
voltage is the real PID input. Each branch (P, I, D) of the
PID, independently adjustable from the others, set the
time constants of the AVR in regard to the generator.
The integrator branch can be short-circuited, for example
when starting-up.
These three outputs are added, limited to 10Vdc and
then give the field current set voltage of the "automatic
channel" which is the driver card input.
The minimum value of this signal can be limitated to
avoid total loss of excitation of the generator. In case of
parallel operation with the mains (cosØ/KVAR card), this
limitation is a function of the active power supply by the
generator, this information is given by the COSØ / KVAR
card.
A separate stage detect if the generator voltage is below
an adjustable value to unlock the normal field ceiling voltage from 110% of nominal to 160% (adjustable).

1 - FUNCTIONAL
2 - ADJUSTMENTS
This card controls from "AUTO" and "MANU" voltage
reference and some additional informations detailed in
the following, the exciter field current supply by the regulator and the booster (if used).
- 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.
- Three operating mode are possible, depending of external informations :
• 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 limited delay and alarm output in case of sustained
undervoltage.
• Maximum ceiling mode if the synchronisation voltage
desappears ( machine short-circuit) with limited (adjustable) field current.
- The "AUTO" or "MANU" reference voltage depending of
the associated command input and also of the active
limitations, is compared to the field current measurement
and gives the error voltage which is after integration,
compared to a sawtooth feed by the synchronisation voltage. The output of this stage is a variable duty cycle
signal which controls the 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 not present)
• Directly from the field voltage for power transistor
command.
The permanent limitation (110% de Iexc nominal) can
be modified by the following conditions:
- Field ceiling unlocking on machine undervoltage condition. It inccreases from 110% (normal operation) to a
minimum of 160% of the nominal field current during an
adjustable time delay and then go back to 110%. An
alarm is activated if this undervoltage is sustained afterward.
- Field ceiling unlocking on synchronisation voltage abcence. It increases to the maximum given by the sett-ing
of P7.
- Field ceiling limitation caused by power heatsink overheating. On thermocontact action the ceiling is reduced
to a value given by the setting of P8.
A separate circuit monitors the instantaneous current of
the power transistor and reduces immediatly the command signal if its value increases above a fixed value.
(Exciter or wiring short-circuit protection ).

This card elaborates from generator current and voltage
informations, the following signals:
2 - ADJUSTMENTS
- An image of the reactive current of the generator
named (KVAR) used for KVAR regulation.
- An image of the phase shift between the voltage and
the current of the generator named (Ø) used for cosØ
(PF) regulation.

: KVAR internal setting.
: PF (cosØ) internal setting.
: Voltage phase shifter (internal)
: PF (cosØ) gain setting
: KVAR gain setting.
: Différential droop setting
: Pulse width setting (internal)
- Jumper CAV : Selection of droop type
- An image of the active current of the generator named
(KW) used for compensate the minimum Ifield limit of the
PID card.
- The principle of measurement is to sample and hold the
instantaneous value of the current when the instantaneous voltage reaches zero on positive slope.
- First the current image of the stator current is filtered
and used directly for KVAR measure. Then it is derivated
and used for KW measure. And then it is amplified to
obtain square waves and integrated to give a sawtooth
used to Ø measure.
- The voltage image is phase-shifted to compensate the
phase shift of the current input filter and after amplification 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 and
external (if used) setting and the difference is send to
the PID card as an error signal. An external contact
control an analog switch to select what information between KVAR and Ø will be regulated.
- Three informations (Ø, ∆Ø, ∆KVAR) can be used as an
alternative droop for solo operation.
• Ø gives no droop at cosØ=1 and the voltage decreases
at lagging PF.
• ∆Ø gives no droop at the cosØ setting and the voltage
decreases at more lagging PF and opposite for more leading PF.
• ∆KVAR gives no droop at the KVAR value setting and
the voltage decreases with more KVAR and increases if
less.
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 decreases if more KVAR (lagging) and opposite if less.
CAV3 : No droop for PF setting (P2), voltage decreases
if more lagging and opposite if less or leading.
Nota : If the droop is used from this card, potentiometer
P1 of the sensing card must be set to zero.

1 - FUNCTIONAL
2 - ADJUSTMENTS
This card replace two conventional motorized potentiometers :
• One for the remote voltage setting.
• One for power factor or reactive current setting.
- 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 +/-)
- Switch between the two modes is made by the external
P.F regulation order (terminals 33, 34) and switch between P.F and KVAR setting is made by the external order (terminals 48,53)
- Each last position is memorized when the control is
switched or when the machine is stopped.
- Jumps (SW1 and SW2) allow the choice between
unipolar or bipolar voltage output and the range is adjusted
by means of potentiometers P02 and P03.
- Jumps SW3 and SW4 must be open for normal operation and are only used for special applications.
- Speed of all adjustments is controled by potentiometer
P01.

NOTE : When this card fitted, the internal voltage
setting (P05 on sensing card) must be used to give
the center position of the range (if bipolar range) or
the minimum setting in case of unipolar range (idem
for P.F and Kvar internal setting on P.F card). An
external setting potentiometer must not be used, the
settings are made only by mean of push-buttons on
terminals 42, 43, 44.

This card elaborates from internal setting (PO2) and
external setting informations, the Ifield command signal
given to "MANU" channel of the driver card.
- P1
- P2
- P3
- P4
- The Ifield output signal is limited or reduced if the generator voltage exceeds the limitation value sets by the
potentiometer 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 under
control.
- On MANU operation, the difference between MANU
output and AUTO channel output gives a compensation
signal which is used to compensate the PID to have
always the MANU and AUTO channels outputs identical.
With this circuit a smooth switching between MANU to
AUTO is possible and operation will go back to the
AUTO channel own settings.
- The ceiling can be unlocked on this operation, that is
why it can be necessary to wait some seconds after the
switching to return on MANU operation.
- On AUTO operation, these two channels are also monitored 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, the
internal setting (P02) must be set to 0 or under the
no load field value and an external setting potentiometer must not be used. In that case the setting is
made only by mean of push-buttons on terminals 44,
45, 46.

Digital pot Ifield
Optional card
This card replace one conventional motorized potentiometer in "MANU" mode and sets the "MANU" channel
output always equal to the "AUTO" one to allow the
smooth switching between the "AUTO" and "MANU" operation at any load (follower in "AUTO" mode).
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
- Switch between the two modes is made by the external
"AUTO / MANU" order (terminals 47,48)
3 - INPUTS / OUTPUTS
- Jumps SW1 allows the choice between voltage output
taken from U/F control of the sensing card or from a 5V
fixed reference and the range is adjusted by means of
potentiometer P03.
- Jumps SW3 and SW4 must be open for normal operation and closed for follower operation.
- Speed of the adjustment is controled by potentiometer
P01 in manual setting and by P02 in follower operation.
P02 acts as a delay between an "AUTO" output variation
and the "MANU" output response.

1 - DESCRIPTION
This 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 necessary and it must be located at the place where
the regulation must be made.
2 - FONCTIONAL
This card elaborates from setting informations and 420mA signal image of P.F (or KVAR) of the mains, the
errorvoltage dending to the PID of the PID card.
- The error signal have an ajustable gain and can be inversed depending of the 4-20mA sensor output.
- This kind of operation is indicated by the LED "L3" and
by a contact (potential free) on the front connector.
- This operation is selected by mean of a contact on front
connectort and will be active on coupling when contact
between terminals 33, 34 of main terminals will be closed.
If the contact on front connector remains open, the regulation (P.For KVAR) will be made at the generator output,
if it is closed, this is the 4-20mA information wich is regulate function of the internal settings (P2 or channel 2 420mA) or/and external by the front connector.
- If during operation, the measuring 4-20mA signal
deseappears, control is automatically return to regulation
on the generator output side and this failure is indicated
by LED L1 ou L2 and by a contact on front connector.
- A second channel can be used as set point of the first
channel or as a remote adjustment of voltage, P.F or
KVAR on generator side. As on channel 1 if the 4-20mA
deseappears, 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
limitatio is adjusted by P7 (Limit 2 set) and can be set
between a maximum value preset by P7 on driver card
and a minimum value preset by P8 on driver card.
- An signaling contact on the front connector gives (if
they are used) the indication that one or more of the digital potentiometers are at maximum position .

1 - FUNCTIONAL
2 - REGLAGES
- A voltage, image of the stator current of the machine,
fed from the "ALTERNATOR I / O" card is rectified, filtered
and compared to a reference voltage. The error signal gives a voltage correction which is added to the main PID
input to maintain the stator current equal to the adjusted value.
- P1 : Stator current limit adjust. (about 2In to 4In )
- P2 : Ramp-up time adjust. (0,5 à 4s environ)
- P3 : Output signal gain

: 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.
- The reference voltage is applied with an initial ramp
ajustable from 0,5 to about 4s.
- A front LED signals stator current limitation operation.
- When this card is used for soft-start operation, the AVR
power transformer must be fed from a separate source
during the start operation and can be switched on the generator output when the voltage have reached the nominal value. The switching must be as fast as possible
(by relay, not by manual switch).

CAUTION
Never energize the AVR when
the driver card is removed.
An overvoltage can appear and the power
transistor can be damaged.
1 - STARTING WITH MANUAL MODE CARD
- For initial start-up, the best is to use the manual mode
for testing the sensing wires between the generator and
the AVR.
- For this it is necessary to have a manual mode card
plugged 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 nominal
voltage.
Start-up
R630
4 - ADJUSTMENTS
- Refer also to card descriptions.
- The AVR is normally preset in factory.
- The nominal voltage can be set by Vref (P5) on sensing
card. Fine adjustment can be made by an external voltage potentiometer (10KΩ), (terminals 21,22,23)
- If an adjustment must be moved, note carefully the original 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 between
V/Hz and 2V/Hz by potentiometer P4.
-The stability is adjusted with the machine in factory. If
necessary, the response time can be changed by the
setting of potentiometer P4 of PID card.
- Other settings are difficult to adjust without specific
electronics equipments. It is better to not change them.
5 - FIELD FLASHING
- Check that the voltage between terminal 25 and 26 of
the AVR terminal block is about one volt.
- Generally, field flashing is not necessary, but in some
cases like long stop time or fault trip, it can be possible
that the voltage does not appear naturally.
In this case, connect a 12Vdc to 24Vdc voltage source to
the terminals 4 and 8 of AVR terminal block, + to 4 for a
short time and remove it when the voltage increases.
- If yes, remove the strap between terminals 47 and 48 of
AVR terminal block.
6 - PARALLEL OPERATION (1F)
- The voltage must reach the nominal value.
- The generator voltages must be as equal as possible.
- Go to §3
- Same for the droop. If it is not possible to measure it,
set the potentiometers P1 of the sensing cards all in the
same position (middle set for example).
If the droop setting is made from cosØ/KVAR card (when
used), see notice NT 1950080.
- Check the presence and the value of the three phases
at the AVR terminal block (terminals 1, 2, 3).
- Set the voltage to 5% above the nominal voltage.
2 - STARTING WITHOUT MANUAL MODE
CARD
- Start the prime mover up to the nominal speed..
- If the voltage does not appear, check wires between
AVR and the generator field (terminals 5 and 6 of AVR),
and the also the wires between AVR and power transformer (terminals 18 and 19 of AVR). Check also the fuse
inside the terminal 19 of AVR terminal block.
- If the voltage is too hight, check that the auxiliary voltage at the terminals 16 and 17 of AVR and the sensing
voltages at the terminals 1, 2, 3 of the AVR terminal
block are present.
- Adjust the nominal voltage with Vref (P5) of the sensing
card for the middle position of the external voltage potentiometer (if used).
- The reactive currents (KVAR) must be shared, immediatly after coupling, even the KW are not shared.
- If, immediatly after coupling, the current increases
abnormally, check if the parallel CT wires are not reversed
(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, check that
the sensing phases at the input of the AVR are right
connected. (U, V, W respectively to the terminals 1, 2, 3
if clockwise rotation or W, V, U, if counter clockwise
rotation).
3 - DE-ENERGIZING (optional)
- External contacts E01 and E02 must be used.
- E01 must be serie with terminal 19 of AVR (power
input) and is opened for de-energizing.
- E02 must short-circuit the booster output (if used)
(terminals 7 and 8 of AVR) and is closed for de-energizing.

7 - PARALLEL WITH THE MAINS (2F)
9 - MANUAL OPERATION (if used)
- The generator and mains voltages must be as equal as
possible. (see §8 if MAIN I/O card is used). The contact
between terminals 33, 34 of AVR terminal block must
be closed at the same time as the coupling and will
remain closed as long as the generator is connected to
the mains.
It will be open when parallel between generators.
- If a manual mode card is used, it is possible to control
directly the field current of the generator.
- If, immediatly after coupling, the current increases abnormally, check if the parallel CT wires are not reversed
(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, check that
the sensing phases at the input of the AVR are right
connected. (U, V, W respectively to the terminals 1, 2, 3
if clockwise rotation or W, V, U, if counter clockwise
rotation).
- The PF value is normally factory set to 0.8. It can be
adjust by mean of potentiometer P2 on cosØ/KVAR card
or by mean of an external potentiometer (10KΩ-1W)
connected to AVR terminal block (27,28,29).
- If the KVAR regulation is required terminals 48 and 53
must be short-circuited and the KVAR can be set by
mean of potentiometer P1 on cosØ/KVAR card or by
mean of an external potentiometer (10KΩ-1W) connected
to AVR terminal block (30, 31, 32).
- For droop setting, see notice NT 1950080.
8 - VOLTAGE EQUALISATION (3F)
- The following procedure must be made one time to take
account of the mains transformer primary/secondary
ratio.
- At no load and mains voltage present at terminals 12,
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
mains voltage as equal as possible.
- Remove the strap between terminals 35, 36 of the AVR
terminal block.
- The initial setting is made.
In normal operation the contact between terminals 35,
36 of the AVR terminal block must be closed with synchronizer operation and can be opened after coupling.

- In automatic mode, adjust the potentiometer P2 on
manual mode card to have the LEDs "HIGHT" and
"LOW" off and the LED OK ligthing. At this time the
manual setting is equal to the automatic channel control.
- Short-circuit the terminals 47,48 of the AVR terminal
block gives control to the manual channel and the field
current is adjusted by potentiometer P2 and/or by an
external optionnal potentiometer (10KΩ-1W) connected
to the terminals 30, 52, 23 of the AVR terminal block
cusor on 52 and hot point on 30.
- This mode can be used when initial start-up of the
generator, to make test after problems or when operating
with the mains. It cannot be used when solo operation
because it is not possible to follow the load variations.
- When coupling with the mains on load, if trip of the
generator occurs, an overvoltage may occurs due to the
fact that the field current setting is too hight regarding the
load of the generator. On this case, an internal circuit of
the card decreases the field current to limit the overvoltage approximatively to 110% of nominal. LED
"LIMIT" on front of the card will light. The setting of field
current must be reset manually to the no load value and
the LED "LIMIT" will switch off.
