LOW OIL PRESSURE:
Set if a signal is detected at the Low Oil Pressure Switch input or the oil
pressure value measured from the sender is below the programmed limit. Warning and alarm limits are
separately programmable for the oil pressure sender input. This fault will be monitored with
Holdoff
Timer
delay after the engine is running. Also if the oil pressure switch is open at the beginning of a start
attempt, then the engine will not be started and the oil pressure alarm led will flash. When the oil
pressure switch closes, normal operation will be resumed.
HIGH TEMPERATURE:
Set if a signal is detected at the High Temperature Switch input or the coolant
temperature value measured from the sender is above the programmed limit. Warning and alarm limits
are separately programmable for the temperature sender input.
LOW TEMPERATURE (warning) :
Set if the coolant temperature value measured from the sender is
blow the
Engine Heating Temperature
limit.
LOW SPEED / HIGH SPEED:
Set if the generator frequency or rpm is outside programmed limits.
These faults will be monitored with
Holdoff Timer
delay after the engine is running. Low and high limits
for warning and alarm are separately programmable. Another high shutdown limit which is 12% above
the high limit is always monitored and stops the engine immediately.
START FAIL (alarm):
Set if the engine is not running after programmed number of start attempts.
STOP FAIL (warning):
Set if the engine has not stopped before the expiration of the
Stop Timer
.
ECU FAIL (warning):
Set when an engine fault code is received from the ECU of the electronic engine.
This fault will not cause an engine stop. If necessary, the engine will be stopped by the ECU.
ECU FAIL (alarm):
Set if no information has been received during 3 seconds from the ECU of the
electronic engine. This fault condition is only controlled if fuel is on.
OVERLOAD (load_dump):
Set if at least one of the genset phase currents goes over the
Overcurrent
Limit
for
Overload Timer
. If currents go below the limit before expiration of the timer then no alarm will
be set.
EXCESS POWER (load_dump):
Set if the genset power (KW) supplied to the load goes over the
Excess Power
limit for
Overload Timer
. If the power goes below the limit before expiration of the timer
then no alarm will be set.
GENSET LOW VOLTAGE:
Set if any of the generator phase voltages goes outside programmed limits
for
Overload Timer
. This fault will be monitored with
holdoff timer
delay after the engine is running.
GENSET HIGH VOLTAGE:
Set if any of the generator phase voltages goes outside programmed limits
for
Overload Timer
. This fault will be monitored with
holdoff timer
delay after the engine is running.
LOW COOLANT LEVEL:
Set if a signal is detected at the low coolant level input.
HIGH BATTERY VOLTAGE:
Set if the battery voltage goes above programmed limits. Both warning and
alarm levels for high battery voltage are programmable.
LOW BATTERY VOLTAGE (warning):
Set if the battery voltage goes below the programmed limit.
During engine cranking this fault is not monitored.
CHARGE:
Set if a charge alternator failure (or broken belt) occurs. This fault condition may result to a
warning
or
alarm
following programming.
RECTIFIER FAIL:
Set if a signal is detected at the rectifier fail input. This input is only monitored when
mains voltages are present.
EMERGENCY STOP:
Set if a signal is detected at the emergency stop input.
SPARE:
Set if a signal is detected from the related spare fault input.
