Range: 0 – 200,0 %
LS int [ % ]
Relative integration factor of load sharing control loop.
Step: 1 %
Range: 0 – 100 %
Hint
:
LS gain and LS int setpoints are active only when gen-set operates in multiple island operation (with other
gen-sets), when GCB is closed.

Sync timeout [ s ] (FV)
Maximum allowed time for forward or reverse synchronization.
Step: 1 s
Range: 1 – 1800 s, NO TIMEOUT
Hint:
If the synchronizing does not succeed within (Sync timeout / 10, but minimum 60) s, the speed regulator
output is reset and synchronisation is automatically started again. So if you set the Sync timeout to
sufficiently high value, the synchronizing cycle can be internally repeated up to 10 times.
If NO TIMEOUT is selected, then the time for synchronizing has no limitation and can only be interrupted by
pressing the GCB or STOP button in MAN mode or removing a corresponding request input in AUT mode.
In the NO TIMEOUT case, the synchronization is restarted every 1800 / 10 = 180 s.
GCB open level [ % ] (FV)
Power level for opening the GCB while soft unload is in progress. If this level isn’t reached, the GCB opens
after GCB open del time.Setting = NO LEVEL disables this GCB open criterium.
Step: % of Nomin power
Range: NO LEVEL, 1 to 100 %
GCB open del [ s ] (FV)
The timeout to unload the gen-set. Should the load ramp fail to bring the gen-set power down to GCB open
level to allow the opening of GCB, the breaker will open after GCB open del. Setting = NO TIMEOUT
disables this GCB open timeout criterium.
Step: 1 s
Range: Load ramp – 1800, NO TIMEOUT
Force value: Yes
Hint:
It is possible to open GCB by panel button or externally.
Volt/PF ctrl
AVRRegChar [ POSITIVE / NEGATIVE ]
Switch between AVR characteristic.
POSITIVE: When the controller and AVRi output voltage increases – generator voltage increases.
NEGATIVE: When the controller and AVRi output voltage decreases – generator voltage increases.
