Description
The module detected that the generator output frequency had risen
above the Over Frequency Pre-Alarm Trip level for the configured
delay timer.
The module detected that the generator output frequency had risen
above the Over Frequency Trip level but was below the Over
Frequency Overshoot Trip for the configured Overshoot Delay
timer during starting.
The module detected that the generator output voltage had risen
above the Over Voltage Pre-Alarm Trip level for the configured
delay timer.
The module detected that the generator output kW had fallen below
the Reverse Power Trip for the configured delay timer.
NOTE: For more details, see section entitled Short Circuit
IDMT Alarm elsewhere in this document.
The module detected that the generator output current had risen
above the Short Circuit Trip for the duration of the IDMT function.
The module detected that the generator output frequency had
fallen below the Under Frequency Pre-Alarm Trip level for the
configured delay timer after the Safety On Delay timer had expired.
The module detected that the generator output voltage had fallen
below the Under Voltage Pre-Alarm Trip level for the configured
delay timer after the Safety On Delay timer had expired.
The module received a fault condition from the engine ECU alerting
that the HEST had activated.
The module detected that the engine's ECU measurement of inlet
temperature had risen above the Inlet Temperature Pre-Alarm Trip
level.
The module's governor output has reached its limit whilst
attempting to control the generator to produce more kWs whilst in
parallel. This indicates a fault with either the governor (including
connection error), setting of SW2, or that the engine has reached
its maximum capacity.
The module detected that the generator output kW had risen above
the Overload Protection Trip for the configured delay timer
The module detected that the generator output kvar had fallen
below the Loss of Excitation Pre-Alarm Trip level.
The module detected that the magnetic pick up was not producing
a pulse output after the required Crank Disconnect criteria had
been met.
The module detected that the engine coolant temperature had
fallen below the Low Coolant Temperature Pre-Alarm Trip level.
NOTE: Due to module configuration the alarm message
that appears on the display may be different. For further
details of module configuration, refer to DSE Publication: 057-
238 DSE8610 MKII Configuration Suite PC Software Manual.
The module detected that one of the configured maintenance
alarms is due as its configured maintenance interval has expired.
