Fault Description
Engine Over Speed
IEEE C37.2 - 12 Overspeed Device
The module detected that the engine speed had risen above the
Over Speed Alarm Trip level for the configured delay timer.
Engine Over Speed Overshoot
IEEE C37.2 - 12 Overspeed Device
The module detected that the engine speed had risen above the
Over Speed Overshoot Trip during the configured Overshoot Delay
timer whilst starting.
Engine Under Speed
IEEE C37.2 - 14 Underspeed Device
The module detected that the engine speed had fallen below the
Under Speed Alarm Trip level for the configured delay timer after the
Safety On Delay timer had expired.
Exp. Unit Failure
The module detected that communications to one of the DSENet
®
expansion modules had been lost.
Failed to Start
IEEE C37.2 - 48 Incomplete
Sequence Relay
The module detected that the generator had failed to start as it did
not meet the required Crank Disconnect criteria during the
configured number of Crank Attempts.
Failed to Stop
IEEE C37.2 - 48 Incomplete
Sequence Relay
NOTE: Fail to Stop could indicate a faulty oil pressure
sensor. If engine is at rest, check the oil pressure sensor wiring
and configuration.
The module detects a condition that indicates the generator is
running when the DSE module has instructed it to stop.
Flexible Sensor A to D High
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 an analogue input value had risen above
the Flexible Sensor High Alarm Trip level.
Flexible Sensor A to D Low
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 an analogue input value had fallen below
the Flexible Sensor Low Alarm Trip level.
Fuel Level High
IEEE C37.2 - 71 Liquid Level Switch
The module detected that the engine fuel level had risen the High
Fuel Level Alarm level for the configured delay.
Fuel Level Low
IEEE C37.2 - 71 Liquid Level Switch
The module detected that the engine fuel level had fallen below the
Low Fuel Level Alarm level for the configured delay
Fuel Level Low Switch
IEEE C37.2 - 71 Liquid Level Switch
The module detected that the engine low fuel level switch had
activated.
Fuel Sensor Fault
The module detected that circuit to the engine fuel level sensor had
become open circuit.
Fuel Usage
IEEE C37.2 – 80 Flow Switch
The module detected that the fuel consumption was more then the
configured Running Rate or Stopped Rate.
Gen Earth Fault
IEEE C37.2 – 51G or 51N Generator
IDMT Earth Fault Relay
NOTE: For more details, see section entitled Earth Fault
IDMT Alarm elsewhere in this document.
The module detected that the generator earth fault current had risen
above the Generator Earth Fault Trip Level for the duration of the
IDMT function.
