Bus Phase Sequence
The module detected a bus phase rotation error, an electrical trip is
initiated. The LCD indicates Bus Phase Seq Wrong.
Bus Under Positive Sequence
The module detected the bus voltage positive sequence had fallen
below the configurable Trip level for the configured delay timer.
Calibration Fault
The module detected that its internal calibration has failed. The unit
must be sent back to DSE to be investigated and repaired. Contact
DSE Technical Support for more details.
Combined Mains Decoupling
The module detected that the mains supply failed when the
generator was in parallel with it.
Digital Input A to L
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 a digital input configured to create a fault
condition became active and the appropriate LCD message is
displayed.
Exp. Unit Failure
The module detected that communications to one of the DSENet
Sync Delay timer had expired.
Insufficient Capacity
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.
Mains Asymmetry High
The module detected the mains voltage asymmetry had risen above
the configurable Trip level for the configured delay timer.
Mains Decoupling OF
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.
Mains Decoupling OV
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.
Mains Decoupling UF
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.
Mains Decoupling UV
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.
Mains Over Negative
Sequence
The module detected the mains voltage negative sequence had
risen above the configurable Trip level for the configured delay timer.
Mains Over Zero Sequence
The module detected the mains voltage zero sequence had risen
above the configurable Trip level for the configured delay timer.
Mains Phase Sequence
Wrong
The module detected a mains phase rotation error, an electrical trip
is initiated. The LCD indicates Mains Phase Seq Wrong.
Mains Reverse Power
IEEE C37.2 – 32 Directional Power
Relay
The module detected that the generator bus is exporting more than
the configured limit, the LCD indicates Mains Reverse Power
