Binary output IDLE/NOMINAL is opened before and during engine start (during
Idle time)
and after engine
start is activated - in Cooling state, only if
Engine params
:
Cooling Speed
= NOMINAL.
Step:
1 s
Range:
1 – 3600 s
Force value possibility: Yes
Hint:
The Under speed protection becomes active 5s after reaching
Starting RPM
or other engine running
condition regardless of the setting of
Idle time
(transition Idle -> Nominal RPM).
Min stab time
[ s ] (FV)
This is the minimum time the controller will wait, after switching the engine to nominal RPM, to close the
GCB (the delay ensures that the GCB is closed with correct generator frequency/voltage).
Step:
1s
Range:
1 –
Max stab time
s
Force value possibility: Yes
Max stab time
[ s ] (FV)
This is the maximum time the controller will wait for generator voltage and frequency to build up, after
switching the engine to nominal RPM.
Step:
1s
Range:
Min stab time
– 3600 s
Force value possibility: Yes
Hint:
When generator voltage in
Max stab time
does not reach defined limits (see
Gener protect
group), an alarm
occurs and the gen-set will cool down and stop.
Warming load
[ % ] (FV)
The requested load during warm-up period after GCB is closed. In parallel to mains operation only.
Step:
1 % of Nominal power
Range:
0 – 100 % of Nominal power
Force value possibility: Yes
Hint
Warming temp Analog input has to be configured. Otherwise the warm-up procedure does not work.
Warming temp [
°
C ] (FV)
The requested engine water temperature to finish the warming period. If this limit reached, the actual
Warming time is shorter than
Max warm time
setpoint.
Step:
1
°
C
Range:
± 32000
°
C
Force value possibility: Yes
Max warm time
[ s ] (FV)
If the required
Warming temp
is not achieved within this time, the warming period is completed anyway.
Step:
1 s
Range:
0 – 3600 s
Force value possibility: Yes
Cooling speed
[ NOMINAL / IDLE ]
(FV)
Determines function of
Idle/Nominal
binary output during cooling.
NOMINAL Gen-set cools down on nominal speed, generator voltage and frequency protections are active.
IDLE
Gen-set cools down on idle speed, generator protections are deactivated (except of Gen >V Sd).
Force value possibility: Yes
Cooling time
[ s ] (FV)
Runtime of the unloaded gen-set to cool down the engine before stop.
Step:
1s
Range:
0 – 3600 s
