Description
frequency is less than the under-frequency set
point.
If the mains frequency is less than this set
point, there is a mains failure.
The mains returns when the mains frequency is
more than this set point.
If this parameter is enabled, the controller
detects a mains failure when the mains
frequency is more than the over-frequency set
point.
If the mains frequency is more than this set
point, there is a mains failure.
The mains returns when the mains frequency is

than the oil pressure set point.
If this parameter is enabled, the oil pressure is
monitored before the engine starts. If the oil
pressure is more than the set point, 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
