Protection Controls ACF Relay can be used as a Check Relay, a Load Relay, a Flame Relay or as a NR Relay.
The ACF (plug-in type) Check Relay makes certain that Protection Controls Protectofier is functioning properly. It is energized thru Normally Closed (NC) contacts of the Flame Relay. Failure of the Check Relay to prove a safe-start check will prevent ignition and energizing of fuel valves.
The ACF (plug-in type) Flame Relay responds to Protection Controls Flame-Pak operation energizing circuit to fuel valve.
The ACF (plug-in type) Load Relay is used on multiburner units to energize fuel valves after all flames are proven. It is energized thru series circuit of Normally Open (NO) contacts of all flame relays. Loss of flame signal from any one burner position de-energizes the load relay, which in tum de-energizes the fuel valves.
The ACF (plug-in type) NR Relay is used on all automatic NR units to provide non-return of ignition after flame failure. Contact of NR relay provides power to the thermal circuit breaker following a flame failure causing thermal circuit breaker to trip. Manual reset of thermal circuit breaker is required.
