Default value Description
SYNCHRO
Integral
SYNCHRO
Proportional
6h
6h
Single turn potentiometers: Integral adjustment of
synchronization. Single turn potentiometers:
Proportional gain adjustment of synchronization.
Synchronization adjustment:
• Turn P and I fully Counter Clockwise
• Turn P potentiometer till the generator is
unstable, Come back in CCW to stop the
instability.
I potentiometer is adjusted with the same
procedure.
RAMP TIME
0s
Single turn potentiometer (0.0 - 180s).
This setting adjusts the time for LOAD and
UNLOAD ramps.
ADJUST
KW monitor
None
Multi turn potentiometer (0-100%).
Output span adjustment Kw (0-5V (terminals 11-
12) or 0-20mA/4-20mA (terminals 12-13)).
(‘sw4’ configuration).
OFFSET
Speed
control
output
None
Multi turn potentiometer (-10 to +10 VDC).
Adjustment of the Offset of the speed output. Used
to adjust the nominal frequency of the generator
(ex: 50,00Hz).
GAIN
Speed
control
output
6h
Single turn potentiometer (Span from 0 to 10VDC).
Span adjustment of the speed control output.
Used to adjust the maximum deviation asked by
UNIGEN =+/-3 Hz
OFFSET
Voltage
control
output
None
Multi turn potentiometer (-10 to +10 VDC).
Offset adjustment of the voltage control output.
Used to adjust the nominal voltage of the
alternator (ie. 400 VAC)
GAIN
Voltage
control
output
6h
Single-turn potentiometer (Span from 0 to
10VDC).
Span voltage control output. Used to adjust the
maximum deviation: = +/- 8% of the nominal
voltage.
NOMINAL

None
Have to be set during the commissioning. See
chapter 6.2.
Switch
Adjustment of
sw1 /sw2 /sw3
/sw4/sw5/sw6
/sw8 depend
of settings
Default:
sw2 ON,
Others
switch OFF.
Configuration of switches, 2 positions:
sw1’terminal resistor of Buscan’ : OFF position resistor not
connected; ON position resistor of 120Ω connected.
sw2‘speed output option’ : OFF position reverse speed
regulation; ON position direct speed regulation for GAC speed
regulator.
sw3‘load sharing mode’ : OFF position paralleling lines load
sharing; On position canbus load sharing.
Not used switch for Industrial Unigen.
sw4‘Kw monitor output’ : OFF position output is 0-5VDC and
0-20mA; ON position output is 4-20mA.
sw5‘synchronization’ : OFF position the relay ‘SYNC OK’
(terminals 34/35) closes only when conditions are ok and
‘SYNC IN’ (terminal 3) is connected to the 0VDC; ON position
the relay ‘SYNC OK’ (terminals 34/35) closes when conditions
are ok.
sw6‘deadbus’ : OFF position the relay ‘SYNC OK’ (terminals
34/35) doesn’t close on deadbus condition; ON position the
relay ‘SYNC OK’ (terminals 34/35) closes on deadbus
condition.
sw7‘OFF/ON’ is not used.
sw8‘terminal resistor of Modbus’: OFF position resistor not
connected; ON position resistor of 120Ω connected.
Not used switch for Industrial Unigen.
