This setpoint selects the behavior of the controler in TEST mode if the load is
currently supplied from the gen-set and the mains has restored.
The load remains to be supplied from the gen-set until the
controller switched to different mode, e.g. to AUT mode.,
regardless of the fact that the mains is restored.
When the mains has restored the gen-set is reverse-
synchronized to the mains, then the load is transferred to the
mains, GCB is opened and the gen-set remains running
unloaded in TEST mode.
Setpoint: FwRet break
The setpoint adjusts the delay between the GCB is opened and consequently
MCB is closed and vice versa changeover is used instead of synchronizing (i.e.
synchronizing is disabled). This delay is also applied between MCB opening and
GCB closing in TEST mode when the gen-set is running without load and then
mains fails.
Setpoint: Mains ret del
This setpoint adjust the delay of start of the reverse synchronizing (SPtM, Combi)
or forward synchronizing (SPI) after the mains has recovered. See the setpoint
MCB close del for the time diagram of all AMF-related delays.
