5.4.4 Stabilization
When the Engine start (page 76) sequence is finished, the gen-set goes into the stabilization phase. There are
two timers (setpoints) in this phase:
Minimal Stabilization Time (page 171) 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 172) 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 171) has already elapsed.
In the event that the generator voltage or frequency are not within limits within the Maximal Stabilization Time
(page 172) 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 194).
Note: The value of the Minimal Stabilization Time (page 171) setpoint has to be lower than the value of Maximal
Stabilization Time (page 172) setpoint.
5.4.5 Connecting to load
When the Stabilization (page 81) 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 171) timer has elapsed.
The gen-set voltage and frequency are within limits.
5.4.6 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.
5.4.7 Engine cool down and stop
The cool down phase follows after the stop command has been issued and the GCB has been opened.
