CEM7 CONTROL UNIT ALARMS | PAGE 50
Detection of the genset power alarm is set by default (Alarms table, parameter
252) to be activated: From the rated condition of the engine.
The genset power alarm is set by default (Alarms table, parameter 254) to
perform no action (warning).
User intervention is not required to reset the generator set after a genset low
power alarm has been generated (auto reportable alarm).
CURRENT ASYMMETRY ALARM (CEM7 VER462)
The CEM7 control unit’s current asymmetry alarm is associated to the measured
current in each of the genset’s phases. This alarm only applies to gensets with
more than 1 phase. The alarm is detected when the difference between the cur-
rent generated by the phase with the highest consumption and the phase with
the lowest consumption of the alternator is greater than the value calculated by
the product of the number of genset phases multiplied by a programmable per-
centage (Threshold table, parameter 61) of the maximum current of the genera-
tor set (Threshold table, parameter 7) during a programmable time interval (an-
ti-rebound) (Alarms table, parameter 256).
Detection of the current asymmetry alarm is congured by default (Alarms table,
parameter 255) to be activated: From the rated condition of the engine.
The current asymmetry alarm is congured by default (Alarms table, parameter
257) to perform no action (warning).
WATER IN FUEL (CEM7 VER469).
The water in fuel alarm of the CEM7 control unit is associated to the detection of
water in fuel by the control engine electronics and it is notied to the control unit
through J1939 protocol. This alarm is enabled to IVECO and BAUDOUIN engines.
The control unit enables the alarm when control engine electronics detects the
water in fuel condition in a programmable period of time (debounce time) (Alarms
table, parameter 259).
The water in fuel detection is enabled by default (Alarms table, parameter 258)
to be activated: Always.
The water in fuel alarm is congured by default to not take any action (warning).
