EXAMPLES OF ALARM OPERATIONS
• “EN” Alarm with engine stopped.
• “AN” Warning that needs to be reset.
• “A” Auto-resettable warning.
“EN” ALARM WITH ENGINE STOPPED
1. Upon detection of an alarm or warning, the control unit produces an acoustic
signal, the LED of the RESET button and the display ashes and the alarm digital
output (AL) is activated. In this case the engine stops. (1)

NOTE
Alarms that cause the engine to stop are not auto-resettable, they must be
notied and reset so that the engine can be restarted, provided that the alarm
does not remain active.
In the default setting, the alarms produced by the analogue inputs do not cause
the engine to stop, just provide a warning as part of the programming. They
need to be reset to disappear from the display, provided that the warning does
not remain active, except for the fuel level warning which is auto-resettable.
