The action alarm connects to an output of the main display module. When the action alarm is audible, the machine needs immediate attention. A safe machine shutdown is required. The main display module will sound the action alarm whenever a warning category 3 problem exists. An alarm for a warning category 3 is a pulsating sound. The alarm for a warning category 2S is a continuous tone.The action alarm does not operate when the engine is stopped. The main display module uses functions in order to determine when the engine is running. The following functions are examples: engine oil pressure, alternator speed and engine speed. If necessary, the action alarm SOUNDS when the main display module decides that the engine is running.
