When the controller is operating normally in the RUN state, the alarm relay is activated and its contact is closed.
The relay contact opens upon any stoppage, even partial, of the application caused by one of the following factors:
oAppearance of a blocking error.
oDisappearance of the mains voltage.
Perform a power cycle of the controller to recover from a hardware watchdog event and reset the relay output contact to the closed state.
When the controller is powered off, the alarm relay is deactivated and its contact is opened.
