Description
The setpoint is used to enable/disable the island operation, i.e. supplying the load
while the mains is disconnected.
 Island mode is recognized if the mains breaker is open, e.g. the
feedback input MCB feedback is not active.
 Parallel mode is recognized if the mains breaker is closed, e.g. the
feedback input MCB feedback is active.
If the island mode is recognized and island operation is disabled the controller will
open the generator breaker, cool-down the gen-set and stop it. While this situation
persists the controller behavior is following:
 The gen-set start in AUT mode is blocked, it can be started in MAN mode
only.
 The GCB can't be closed.
 The message OfL StartBlck is present in the alarm list (see the alarm
output OfL StartBlck).
