Description
If the mains breaker fails to open, a warning is initiated. The
LCD indicates Mains Failed To Open.
The module detected the mains (utility) voltage negative se-
quence had risen above the configurable Trip level for the con-
figured delay timer.
The module detected the mains (utility) voltage zero sequence
had risen above the configurable Trip level for the configured
delay timer.
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 the engine oil pressure had fallen be-
low the Low Oil Pressure Pre-Alarm Trip level after the Safety
On Delay timer had expired.
The module detected that an input configured for Protections
Disable became active.
The module received a fault condition from the engine ECU
alerting about the SCR Inducement.
The module detected that the generator output kW had fallen
below the Low Load Alarm Trip level for the configured delay
timer.
NOTE: Due to module configuration the alarm message that ap-
pears on the display may be different. For further details of mod-
ule configuration, contact your Authorized Industrial Service
Dealer (IASD)..
The module detected that an analog input configured as a digi-
tal input to create a fault condition became active and the ap-
propriate LCD message is displayed.
The module detected that the output voltage of the generator
had risen above the Over Voltage During Auto Sensing Trip lev-
el during starting whilst attempting to detect which alternative
configuration to use.
The module's AVR output has reached its limit whilst attempting
to control the generator to produce more KVARS whilst in paral-
lel. This indicates a fault with either the AVR (including connec-
tion error), setting of SW2, or that the alternator has reached its
maximum capacity.
NOTE: For further details, contact your Authorized Industrial
Service Dealer (IASD).
The module did not detect bus voltage or frequency when the
generator's load switch closed on to a dead bus.
The module detected that the phase rotation of the bus was dif-
ferent to the configured Bus Phase Rotation Alarm setting.
The module detected that its internal calibration has failed. The
unit must be sent back to DSE to be investigated and repaired.
