GENSET LOW / HIGH
FREQUENCY Set if the generator frequency is outside programmed limits. These faults will
be monitored with
Fault Holdoff Timer delay after the engine is running.
Low and high limits are separately programmable. The detection delay is
also programmable. Another high frequency shutdown limit which is 12%
above the high limit is always monitored and stops the engine immediately.
GENSET LOW / HIGH
RPM
Set if the generator rpm is outside programmed limits. These faults will be
monitored with
Fault Holdoff Timer delay after the engine is running. Low
and high limits are separately programmable. The detection delay is also
programmable. The high rpm overshoot limit is always monitored and stops
the engine immediately.
GENSET LOW / HIGH
VOLTAGE Set if any of the generator phase voltages goes outside programmed limits
for
Voltage Fail Timer . This fault will be monitored with Fault Holdoff Timer
delay after the engine is running.
LOW / HIGH BATTERY
VOLTAGE Set if the genset battery voltage is outside programmed limits. Low and high
limits are separately programmable. The detection delay is also
programmable.
FAIL TO START Set if the engine is not running after programmed number of start attempts.
LOW CHARGE VOLTAGE
Set if the charge alternator voltage is below the programmed limit. This fault
will be monitored with
Fault Holdoff Timer delay after the engine is running.
J1939 ECU FAIL
Set if no information has been received during 3 seconds from the ECU of
the electronic engine. This fault condition is only controlled when fuel is on.
VOLTAGE UNBALANCE Set if any of the generator phase voltages differs from the average by more
than
Voltage Unbalance Limit for Voltage Fail Timer . This fault will be
monitored with Fault Holdoff Timer delay after the engine is running.
CURRENT UNBALANCE Set if any of the generator phase currents differs from the average by more
than
Voltage Unbalance Limit for Voltage Fail Timer . This fault will be
monitored with Fault Holdoff Timer delay after the engine is running. The
action taken at fault condition is programmable.
OVERCURRENT Set if at least one of the genset phase currents goes over the Overcurrent
Limit for the period allowed by the IDMT curve setting. The allowed timer is
dependent of the overcurrent level. If currents go below the limit before
expiration of the timer then no alarm will be set. Please check chapter
Overcurrent Protection (IDMT) for more details. The action taken at fault
condition is programmable.
PICKUP SIGNAL LOST Set if the rpm measured from the magnetic pickup input falls below the
Crank Cut RPM level during Loss of Speed Signal Timer . The action of
signal loss is programmable.
SERVICE REQUEST Set if at least one of the service counters has expired. In order to reset the
service counters please hold pressed both with and buttons during 5
seconds
. The screen will display “Completed!”
Digital input and analog sender alarms are fully programmable
for the alarm name, sampling and action.
Only internal alarms are explained in this section.
