Description
That module detected that the Redundant MSC communication
failed, most likely caused by it being disconnected.
That module detected that the number of modules on the Re-
dundant MSC was less than the configured Minimum Modules
on MSC Link setting.
The module detected that there was an imbalance of current
across the generator phases greater than the Negative Phase
Sequence Trip Level percentage setting.
NOTE: For further details , contact your Authorized Industrial
Service Dealer (IASD).
The module did not detect that the generator and bus voltage
have drifted out of sync. This is caused by some form of exter-
nal logic tripping open the generator load switch without it in-
forming the DSE module.
The module received a fault condition from the engine ECU
alerting about the SCR Inducement.
The module received a fault condition from the engine ECU
alerting that water in the fuel had been detected or that the
Water in Fuel input switch had activated.
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 a digital input configured for Air-Flap
Closed Auxiliary became active.
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.
The module detected that a battery charger connected by DSE-
Net® had issued a Battery Temperature alarm
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.
The module detected that the output voltage of the charge alter-
nator had risen above the Charge Alternator Shutdown Trip lev-
el for the configured delay timer.
The module detected that a battery charger connected by DSE-
Net® had a Charger Failure alarm.
