AVR MAXIMUM TRIM LIMIT
The AVR output is beng controlled to it’s maximum limit (100%). This can indicate a problem with the
setup or control of the AVR.

4.4 ELECTRICAL TRIPS
Electrical trips are latching and stop the Generator but in a controlled manner. On initiation of the
electrical trip condition the module will de-energise the ‘Close Generator’ Output to remove the
load from the generator. Once this has occurred the module will start the Cooling timer and allow
the engine to cool off-load before shutting down the engine. The alarm must be accepted and
cleared and the fault removed to reset the module.
AUXILIARY INPUTS, if an auxiliary input has been configured as an electrical trip the appropriate
message will be displayed as configured by the user.
Example
Alarm
Electrical trip
Output breaker tripped
The following alarms are configurable between Warning, Shutdown and Electrical Trip. “Electrical
Trip” is the factory default setting.
GENERATOR HIGH CURRENT, if the module detects a generator output current in excess of the
pre-set trip a warning is initiated. This warning will continue for a period of time depending upon the
level of overload that the generator is subjected to and the configuration setting for Generator High
Current in the 5xxx series configuration software.
Alarm
Shutdown
High current trip
For instance, the factory default settings for Generator High Current allow for a loading of the
generator to 110% for one hour. That is to say if the generator load level exceeds the trip point by
10%, a warning alarm will occur while the overload condition exists. If the load level does not drop
to normal levels within one hour, the breaker is opened and the set is cooled down and stopped.
NOTE:- Higher overload levels will result in a faster acting shutdown condition. For
instance with the factory default configuration, an overload level twice that of the trip level
(typically 200% of the full load) will result in a Generator High Current shutdown condition
after 36 seconds.
For details of the relationship between the overload and the shutdown time, please see the
Appendix section of this manual.
