Description
If the mains frequency is more than this set
point, there is a mains failure.
The mains returns when the mains frequency is
less than this set point.
If the frequency is more than the over-
frequency set point when this timer expires, the
action for over-frequency is activated.
Description
Number of attempts to crank the engine.
If this parameter is enabled, the crank is
disconnected when the oil pressure is more
than the oil pressure set point (DISCONN LOP
SENS).
If this parameter is enabled, the oil pressure is
monitored before the engine starts. If the oil
pressure is more than the set point (MON LOP
BEF CRANK), the engine cannot start.
Configure the set point for the oil pressure.
If this parameter is enabled, the oil pressure is
monitored before the engine starts. If the
pressure switch is open, the controller activates
a high oil pressure alarm.
If this parameter is enabled, the crank
disconnects if the oil pressure is high.
If the oil pressure is high after this timer
expires, the crank is disconnected.
If the frequency is more than this set point
during cranking, the controller disconnects the
crank.
If the engine speed is more than this set point
during cranking, the controller disconnects the
crank.
If this parameter is enabled, the crank is
disconnected when the charging alternator
voltage is more than the alternator set point
(CHG ALT THRESHOLD) during a cranking
attempt.
If the charging alternator voltage is more than
this set point during cranking, the crank is
disconnected.
