J1939 ECU Alarm
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.
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.
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.
Set if the genset battery voltage is outside programmed limits. Low and high
limits are separately programmable. The detection delay is also
programmable.
Set if the engine is not running after programmed number of start attempts.
Set if the engine is not stopped before the expiration of the Stop Timer.
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.
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.
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.
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.
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.
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.
Set if at least one of the service counters has expired. In order to reset the
service counters please hold pressed both with and
seconds. The screen will display "Completed!"
Set if the communication between the unit and the ECU is lost.
