Description
The module detected that the engine fuel level had fallen below
the Low Fuel Level Pre-Alarm level for the configured delay.
The module detected that the engine low fuel level switch had
activated.
The module detected that the fuel tank bund level switch had
activated.
The module detected that the fuel consumption was more than
the configured Running Rate or Stopped Rate.
The module detected that the generator earth fault current had
risen above the Earth Fault Trip Level for the duration of the
IDMT function.
The module detected that the Generator Load Switch has not
Opened after being commanded to Open.
The module detected that the generator output frequency had
not risen above the Generator Loading Frequency setting after
the Warming Up timer had expired.
The module detected that the generator output voltage had not
risen above the Generator Loading Voltage setting after the
Warming Up timer had expired.
The module detected that the generator output current had ris-
en above the Generator Over Current Trip.
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 ris-
en above the Over Voltage Pre-Alarm Trip level for the config-
ured delay timer.
The module detected that the generator output kW had fallen
below the Reverse Power Trip for the configured delay timer.
The module detected that the generator output current had ris-
en 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 fall-
en below the Under Voltage Pre-Alarm Trip level for the config-
ured 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.
