NOTE:
The starting sequence will be interrupted at any time if a stop command comes.
NOTE:
The Underspeed protection starts to be evaluated 5 after the engine has been started (according to
point 4).
NOTE:
When the engine is started (according to point 4) the delay given by the setpoint ProtectHoldOff will
count down. After it has elapsed, the protections configured as engine running only will start to be
evaluated.
Continue to the stabilization phase.
6.5 Stabilization
When the start-up sequence is finished, the gen-set goes into the stabilization phase. There are two
timers (setpoints) in this phase:
1. Min Stab Time starts to count down just after the idle period has finished. Generator voltage
and frequency are not checked (respective protections are not evaluated) and the GCB
cannot be closed even if the generator voltage and frequency are within limits.
2. Max Stab Time starts to count down just after the idle period has finished. Generator voltage
and frequency are not checked (respective protections are not evaluated) but, opposite to the
previous timer, the GCB can be closed (or synchronizing started) if generator voltage and
frequency are within limits.
In situations where the GCB is closed automatically (AUT, TEST modes), the closing of GCB or
starting of synchronization will occur in the first moment when the generator voltage and frequency will
get into limits and the Min Stab Time has already elapsed.
In the event that the generator voltage or frequency are not within limits within the Max Stab Time
period, the appropriate protection(s) will be activated and the gen-set will be cooled down and
stopped.
NOTE:
The limits for the generator voltage and frequency are given by setpoints in the Gener protect group.
NOTE:
The value of the Min Stab Time setpoint must be lower than the value of Max Stab Time setpoint.
Continue to the connecting to the load phase.
6.6 Connecting to the load
When the stabilization phase is finished, the gen-set can be connected to the load.
The command for connecting the gen-set to the load is issued either automatically (AUT, TEST
modes) or manually by pressing the GCB button. The following conditions must be valid:
 The gen-set is running and the Min Stab Time timer has elapsed.
 The gen-set voltage and frequency are within limits.
