IMPORTANT : The informations given by this sheet must 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 with BOOS-
TER" or "SHUNT with PMG" excitation. In case of
"SHUNT with BOOSTER the booster current is totally
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 mains with
cosØ or KVAR regulation.
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 plug-
ged 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
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
- Field output :
• 12 Amperes nominal, 24Amp maximum during 10s on
6Ωminimum
- 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.

1 - FUNCTIONAL
- This unit is mainly an interface between external signals
and low power electronics.
- It is composed by :
• The adaptation three phases transformer between input
voltage and measurement circuits.
• The burden resistor of parallel CT.
• The adaptation transformer between input voltage and
low power electronic supplies.
• The interface input relays between command / control
terminals and internal circuits.
• The interface between 64pts BUS and the analogic in-
put / output terminals
2 - ADJUSTMENTS
- Setting of the auxiliary input voltage (terminals 16,17) :
(110 or 220Vac) by jumpers.

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 affect-
ed 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)
2 - ADJUSTMENTS
- P1 : Reactive droop adjust for parallel operation bet-
ween 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)
- P5 : Voltage set point Vref for the nominal voltage
(10Vdc at Un and Fn)
3 - INPUTS / OUTPUTS
- 7a, 8a, 8c : Voltage inputs image of the generator (3 x
21Vac between each and the GND)
- 9a : Current input image of the generator stator
current (1Vac pour In)
- 1a,1c : +15Vdc regulated (Vcc)
- 32a,32c : -15Vdc regulated (Vdd)

SENSING card

1 - FUNCTIONAL
- 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.
- 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 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 ma-
chine 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 applica-
tions 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 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 correction
adjust
