3.3 Heater Interlock Relays CAUTION Explosion protection when using heated probes is achieved by switching the power to the probe heater off whenever the main fuel valve is closed. The principle of safety is that if the main fuel valve is open then main flame has been established. With this primary source of ignition on, the probe heater can be safely switched on. The most dangerous situation is if fuel leaks into the combustion appliance when the fuel valve is closed. When power is removed from the main fuel valve the heater should also be switched off. To achieve this protection, connect a main fuel valve voltage free contact to the ‘BURNER ON SWITCH’ terminals 10 & 11. When the main fuel valve is open, the voltage free contact should be closed. For installations where there is no risk of explosion, connect a link between terminals number 10 & 11. Heater Supply Interlock Connection for Heated Probes For safety, contacts must be open if the main fuel valve is closed in a direct fired system 10 BURNER INPUT 11 If a safety interlock is not required, a wire must be connected between terminals 10 &11 to enable – • The heaters on heated probes • Process alarms • Auto-purge and auto-cal checking.
