8.5 SHUTDOWNS
NOTE:- Shutdown and Electrical Trip alarms can be disabled by user configuration. See the section
entitled Protections Disabled elsewhere in this document.
Shutdowns are latching alarms and stop the Generator. Clear the alarm and remove the fault then press
Stop/Reset
to reset the module.
Example
Alarm 1/1
Oil Pressure Low
Shutdown
NOTE:- The alarm condition must be rectified before a reset will take place. If the alarm condition
remains, it will not be possible to reset the unit (The exception to this is the Low Oil Pressure alarm and
similar ‘active from safety on’ alarms, as the oil pressure will be low with the engine at rest).
Display Reason
EARTH FAULT
(DSE7300 series V2.0 or above
only)
The measured Earth Fault Current has been in excess of the earth fault
trip and has surpassed the IDMT curve of the Earth Fault alarm.
FAIL TO START The engine has not fired after the preset number of start attempts
EMERGENCY STOP The emergency stop button has been depressed. This a failsafe
(normally closed to battery positive) input and will immediately stop the
set should the signal be removed.
Removal of the battery positive supply from the emergency stop input will
also remove DC supply from the Fuel and Start outputs of the controller.
NOTE:- The Emergency Stop Positive signal must be present
otherwise the unit will shutdown.
LOW OIL PRESSURE The engine oil pressure has fallen below the low oil pressure trip setting
level after the
Safety On timer has expired.
ENGINE HIGH TEMPERATURE The engine coolant temperature has exceeded the high engine
temperature trip setting level after the
Safety On timer has expired.
FUEL USAGE Indicates the amount of fuel measured by the fuel level sensor is in
excess of the
Fuel Usage alarm settings. This often indicates a fuel leak
or potential fuel theft.
PHASE ROTATION
(DSE7000 series V2.0 or above
only)
The phase rotation is measured as being different to the configured
direction.
OVERSPEED The engine speed has exceeded the pre-set trip
NOTE:-During the start-up sequence, the overspeed trip logic
can be configured to allow an extra trip level margin. This is used to
prevent nuisance tripping on start-up - Refer to the 7000 series
configuration software manual under heading ‘Overspeed
Overshoot’ for details.
UNDERSPEED The engine speed has fallen below the pre-set trip after the Safety On
timer has expired.
