10.5 Pressure switch for auger safety alarm
If the pressure switch measures a pressure lower than the threshold ,it
intervenes in order to stop the auger (when the auger is working) and, at
the same time, through the AL2 clip in CN4, it allows the control board
to acquire this change in state. On the display, the message “Alarm Dep
Fail” will appear and the system will stop.
