Fireye® 70D30 1032394

Fireye® Series D30 burner management controls provide ignition and main flame failure protection for automatically ignited oil, gas and combination fuel burners. In conjunction with limit operating controls and interlock devices it automatically programs, with solid state timing logic, the burner/blower motor, ignition and main fuel valve(s). The control cycles automatically when the operating control closes and following a power interruption, but must be manually reset following a safety shutdown. The start up programming includes a safe start check on each start. If flame signal (real or simulated) is detected, the ignition will not be energized and safety lockout will occur. Terminals are provided for a main fuel valve proof of closure interlock, which must be closed before start up and during pre-purge. Proof of the low fire start position is required before ignition. An interlock circuit is provided for airflow switches, fuel pressure switches etc. which must be closed during the pre-purge and firing period. The control system de-energizes all fuel valves within four seconds following flame failure. An alarm circuit actuates audible and visual alarms following a safety lockout.
