Running Failure Action
After the communication fails, the unit runs the selected Keep Alive Action to shutdown the AC Output.
This function turns off the AC power to reset the local communication equipment. After the output power
is restored, the unit waits for Keep Alive Startup Delay before retrying to ping the destination IP address.
If the communication still fails after running the selected Keep Alive Action for Keep Alive Maximum
Action Retries, the Keep Alive function goes to a Failure state. In the Failure state, the Keep Alive
Failure Alarm is activated and the unit will stop pinging the destination IP address until Keep Alive
Failure is reset.
The Keep Alive configuration table has the following fields:
