Fault Relay
The error relay can be used to monitor the condition of the switch. If the switch is turned off the
relay contacts are open. When power is being applied the contacts of the relay remain open until
BOTH power inputs have reached a valid level. Only then the contacts are closed. If in the ongoing
opration one of the voltage levels drops below the lower end the relay contacts are opened again. In
case the switch is operated via one power input only a connection between the DC input and ONE
of the AC inputs can be made to simulate the 2nd supply voltage. The relay is rated at 24 V with a
maximum of 30 mA.
