DSE Model 5320 Automatic Mains Failure & Instrumentation System Operators Manual
18 Part No. 057-014 5320 OPERATING MANUAL ISSUE 5.1 18/06/2007 ADM
CAN ECU FAIL If the module is configured for CAN instruments and receives a “fail” message from the
engine control unit, the engine is shutdown and ‘Can ECU fail” is shown on the module’s display.
Example
Alarm
The display will alternate
between the text display and the
manufacturers error codes
Alarm

NOTE:- If the CAN message is a manufacturers specific code, it may not be displayed as text.
If this is the case the display will show the generic manufacturers code only, which must be cross-
referenced with the engine manufacturers literature. Please contact the engine manufacturer for
further assistance.

4.5 HIGH CURRENT SHUTDOWN ALARM
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 set is stopped,
the 5320 module displaying either shutdown alarm or electrical trip alarm depending upon module configuration.
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%) 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.
