Continuous
When this output is configured it is possible to assign alarm actions that trip the
AVR.
When an alarm with a
Trip AVR
action activates, the
Trip AVR
digital output
activates and stays activated until all alarms with a
Trip AVR
action are resolved.
When the output is active, the controller pauses AVR regulation.
