All the
time
The alarms are beeing evaluated all the time the controller is switched on.
Force
block 1
The alarms are beeing evaluated while the input
Force block 1
is not active. The
evaluation begins
ForceBlockDel1
seconds after the input has been deactivated.
Force
block 2
The alarms are beeing evaluated while the input
Force block 2
is not active. The
evaluation begins
ForceBlockDel2
seconds after the input has been deactivated.
Force
block 3
The alarms are beeing evaluated while the input
Force block 3
is not active. The
evaluation begins
ForceBlockDel3
seconds after the input has been deactivated.
El. prot
The alarms are beeing evaluated while the generator is expected to provide correct
voltage and frequency. That means the alarms start to be evaluated after transition form

phase when the period of
Max stab time
has already elapsed, remain
beeing evaluated while the gen-set is running at nominal speed (regardless of GCB
position) and stop to be evaluated by transition to the
Cooling
phase.
