DSE Model 5210 Automatic Start Engine Management and Instrumentation System Operators Manual
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 5200 series configuration
software.
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
5210 module displaying either shutdown alarm or electrical trip alarm depending upon module configuration.
Additionally, the
A
icon will illuminate.
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.
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 ‘Load Transfer’ 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.
In the event of an electrical trip alarm the
icon will illuminate.
Additionally, During the cooling timer the warning symbol
is displayed followed by the flashing shutdown
symbol when the cooling timer has expired.
AUXILIARY INPUTS, if an auxiliary input has been configured as an electrical trip the appropriate LCD segment
will be displayed:-
!
GENERATOR HIGH CURRENT, if the module detects a generator output current in excess of the pre-set trip a
warning is initiated.
The
A
icon will illuminate.
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.
