SHUTDOWN ALARM ICONS
Shutdown alarms are latching and immediately stop the Generator. On initiation of the shutdown condition the module
de-energises all the '
Delayed Load Output
' and the '
Close Gen Output
' outputs to remove the load from the generator.
Once this has occurred, the module shuts the generator set down immediately to prevent further damage. The alarm
must be accepted and cleared, and the fault removed to reset the module.
Note: The alarm condition must be rectified before a reset will take place. If the alarm condition remains, it is
not 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 is low with the engine at rest).
Additional shutdown alarm icons can be viewed overleaf.
Shutdowns are latching alarms and to remove the fault, press the
Stop/Reset Mode
button on the
module.
