DSE Model 5320 Automatic Mains Failure & Instrumentation System Operators Manual 

 

Part No. 057-014    5320 OPERATING MANUAL ISSUE 5.1    18/06/2007 ADM

4.6 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 

Phase rotation

 

 

GENERATOR HIGH CURRENT.

 If the module detects a generator output current in excess of the pre-set trip a 

warning is initiated. If this high current condition continues for an excess period of time, then the alarm is escalated 
to either a shutdown or electrical trip condition (depending upon module configuration). For further details of the 
high current alarm, please see High Current Shutdown Alarm.
