Description
The module detected that the phase rotation of the generator was
different to the configured Generator Phase Rotation Alarm setting.
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 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 the mains frequency had risen above
the Mains Decoupling Over Frequency Trip level when the
generator was in parallel with the mains.
The module detected that the mains voltage had risen above the
Mains Decoupling Over Voltage Trip level when the generator was
in parallel with the mains.
The module detected that the mains frequency had fallen below
the Mains Decoupling Under Frequency Trip level when the
generator was in parallel with the mains.
The module detected that the mains voltage had risen above the
Mains Decoupling Under Voltage Trip level when the generator
was in parallel with the mains.
The module detected that the mains frequency had changed at a
rate larger than the Mains ROCOF Alarm Trip level when the
generator was in parallel with the mains.
The module detected that the mains voltage waveform's vector
had shifted more than the Mains Vector Shift Alarm Trip level when
the generator was in parallel with the mains.
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 another module on the MSC link had the
same GenSet MSC ID configured.
