5.5.4 Stabilization
When the Engine start (page 90) sequence is finished, the gen-set goes into the stabilization phase. There are
two timers (setpoints) in this phase:
Minimal Stabilization Time (page 200) 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.
Maximal Stabilization Time (page 201) 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 if generator voltage and frequency are within limits.
In situations where the GCB is closed automatically (AUTO, TEST modes), the closing of GCB will occur in the
first moment when the generator voltage and frequency will get into limits and the Minimal Stabilization Time
(page 200) has already elapsed.
In the event that the generator voltage or frequency are not within limits within the Maximal Stabilization Time
(page 201) 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 Group: Generator
settings (page 227).
Note: The value of the Minimal Stabilization Time (page 200) setpoint has to be lower than the value of
Maximal Stabilization Time (page 201) setpoint.
5.5.5 Connecting to load
When the Stabilization (page 94) 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 (AUTO, TEST modes) or
manually by pressing the GCB button. The following conditions must be valid:
The gen-set is running and the Minimal Stabilization Time (page 200) timer has elapsed.
The gen-set voltage and frequency are within limits.
5.5.6 MRS operation
The "MRS function" represents manual or remote start of gen-set. It is ideal for prime power applications.
The MRS procedure
When the start command is detected, the following steps are performed:
The gen-set is started.
GCB is closed and the gen-set begins to supply the load (in AUTO mode, otherwise GCB button has to be
pressed)
When the stop command is detected, the following steps are performed:
GCB is opened and the gen-set stops supply the load.
After GCB is opened, the gen-set cools down and a stop.
