Wiring the Alarm Relay Output
The alarm relay output contacts are in the middle of the terminal block connector. By inserting
the wires and setting the DIP switch of the respective Port Alarm to "ON", the alarm relay
output detects any port failures and forms a short circuit. The alarm relay output is "Normal
Open." The alarm relay output closes if there is a port or power failure.
