Description
If this parameter is enabled, the controller
detects a mains failure when the mains
frequency is less than the under-frequency set
point (UF trip).
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 (OF trip).
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.
