If the generator has been connected, the minimum run time begins ("#242.08
GnOpTmMin" parameter). The generator remains connected during this time, even if in
the meantime the generator request is no longer pending.
If the minimum run time has expired and a request is no longer pending or the system
detects that the set limits have not been maintained, the generator disconnects and
transitions into the power down phase (Cool). If this power down phase is completed
after the "#242.10 GnCoolTm" time, the generator is stopped.
If a generator fault (e.g. generator failure) is detected, the generator is also
disconnected and then stopped immediately. In doing so, the power down time is
skipped.
Once the stop time ("242.09 GnStpTmMin" parameter) has expired, the generator is
ready for the next request.
If a generator fault is detected several times and the number of autostarts ("#241.02
GnAutoStr" parameter) has been exceeded, the system transitions into the locked error
state. This state lasts for the "#242.11 GnErrStpTm" time. Once this time has expired,
the generator is ready for another attempt.
The "#140.03 GnRmgTm" process value is used to display the remaining time of the
generator meter. Depending on the current request or the phase in which the generator
state machine is, the following times are displayed:
•
Remaining time of Run1h
•
Remaining run time during the warm up time (Warm)
•
Remaining minimum run time in operation (Run)
•
Remaining run time during the power down time (Cool)
•
Remaining stop time after the power down time has expired (Lock)
The power down time ("#242.10 GnCoolTm" parameter) defined on the Sunny
Island 5048 should be set equal to or preferably greater than the power down
time of the GenMan.
An internal generator request is disabled during the power down time and stop
time or in error state.
The recording of autostarts is only reset after the generator has been successfully
connected and the minimum run time has expired or when the locked error state
(FailLock) is disabled.
The error state as well as the locked error state can be cancelled by confirming
the generator fault ("#430.02 GnAck" parameter).
