Description
Synchronization
Contactor Timeout

25.5
0.5
When synchronization is detected, both
contactors will stay closed during this
timer.
Max Frequency
Difference

0.1
2.0
0.5
This is the maximum difference between
mains and genset frequencies to close
both contactors.

Max Volt Difference
VAC

5
This is the maximum difference between
the mains phase-L1 and the genset
phase-L1 voltages to close both
contactors. If voltage transformer is used,
this quantity is multiplied with voltage
transformer ratio.
Max Phase Difference
deg.
0
20
10
This is the maximum phase angle
between the mains phase-L1 and the
genset phase-L1 voltages to close both
contactors.
Phase Angle Offset
deg.
-60
+60
0
This parameter is used to compensate
the phase angle introduced by voltage
transformers in case of MV
synchronization. This angle value is
added to the phase differential during
phase matching process.
Dwell Timeout
Sec
0.01
0.50
0.10
The synchronization conditions must
remain satisfied during this timeout for the
controller to decide to close its contactor.
Phase Synchronization G
Gain
%
0
200
20
This parameter governs the phase
synchronization speed.
If this parameter is increased, the
synchronization will be faster but
unstable. If it is decreased, the
synchronization will be slower but more
stable. The best setting is the fastest
stable synchronization.

This parameter governs the frequency
synchronization speed.
If this parameter is increased, the
synchronization will be faster but
unstable. If it is decreased, the
synchronization will be slower but more
stable. The best setting is the fastest
stable synchronization.
Voltage Synchronization
G Gain

This parameter governs the voltage
synchronization speed.
If this parameter is increased, the
synchronization will be faster but
unstable. If it is decreased, the
synchronization will be slower but more
stable. The best setting is the fastest
stable synchronization.

This is the time duration of the Soft
Transfer. At the end of this timer one of
the contactors will release to terminate
the parallel operation
