2.7. DROOP load sharing
When ‘DROOP’ (terminal 4) input is connected to 0 VDC, UNIGEN is in Super droop mode.
In this mode the load sharing is managed between 50.50Hz (0% load) and 50.00Hz (100% load).
For this specific droop, it is not needed to set precisely the engine speed, and any connections are required between
each UNIGEN, even the 0V.
kW and kVAR load sharing are managed with droop.

2.8. COMMAND MODE (for Unigen Plus )
When 1->’DROOP’ input is opened (terminal 4 not connected),
2->‘COMMAND MODE’ input is closed (terminal 39 connected to the 0VDC),
3->and the generator breaker is closed (terminal 5 connected to the 0VDC),
then the UNIGEN Plus is in ‘Command mode’.
The setpoint load is fixed via the remote potentiometer of kW set point (terminals 40/41/42) and the power factor is
fixed at 0.95 by the parameter ‘E11020’.
The low limit of the potentiometer is 5% and the high limit is 110% of nominal kW.
Behaviour of kW setpoint (potentiometer) is described on schematic below.

‘Command mode’ behaviour is described in the second schematic shown on chapter ‘MAINS PARALLELED’.
2.9. MAINS PARALLELED (for Unigen Plus )
When 1->‘DROOP’ input is opened (terminal 4 not connected),
2->‘COMMAND MODE’ input is opened (terminal 39 not connected),
3->‘MAINS PARALLELED’ input is closed (terminal 38 connected to the 0VDC),
4->and the generator breaker is closed (terminal 5 connected to the 0VDC),
then the UNIGEN Plus is in ‘Mains paralleled’ mode.
The setpoint load is fixed by the paralleling lines (terminals 44/45) (coming from the GCR for example) and the power
factor is fixed at 0.95 by the parameter ‘E11020’.
A 0V in paralleled lines (terminals 44/45) is that the generator takes 0% of load, a 3V in paralleled lines is that the
generator takes 100% of load.
Behaviour of kW setpoint (paralleling lines) is described on schematic below.
