Description
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 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 Alarm Trip level for the configured delay
timer after the Safety On Delay timer had expired.
The module detected that the engine's ECU measurement of inlet
temperature had risen above the Inlet Temperature 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 Alarm Trip level for the configured
delay.
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 circuit to the magnetic pick up sensor
had become open circuit.
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.
The module detected that there was an imbalance of current
across the generator phases greater than the Negative Phase
Sequence Trip Level percentage setting.
The module detected that circuit to the engine oil pressure sensor
had become open circuit.
The module detected that the engine oil pressure had fallen below
the Low Oil Pressure Shutdown Trip level after the Safety On
Delay timer had expired.
The module detected that the low oil pressure switch had activated
after the Safety On Delay timer had expired.
The module received a fault condition from the engine ECU
alerting about the SCR Inducement.
The module detected that circuit to the engine coolant temperature
sensor had become open circuit.
The module received a fault condition from the engine ECU
alerting that water in the fuel had been detected or that the Water
in Fuel input switch had activated.
