DESCRIPTION
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
prepurge. Proof of the low fire start position is required before ignition. An interlock circuit is pro-
vided for air flow switches, fuel pressure switches etc. which must be closed during the prepurge 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.
Plug-in amplifier modules permit the selection of Ultraviolet, repetitive self-check Ultraviolet,
AUTOCHECK infrared, or Rectification methods of flame detection. For increased safety and reli-
ability, Fireye 72D1R1-3 AUTOCHECK infrared amplifiers (using the pulsing flame signal) and
72DUVS-45UV5 Ultraviolet amplifier-scanner (using a scanner shutter) check the function of the
flame detecting system for any component failure during each burner firing cycle. Meter test jacks
on each amplifier module provide flame signal readout with a DC voltmeter.
The solid state programmer is a plug-in module. A test switch permits the operator to stop the pro-
gramming before energizing the main fuel valves, for test purposes.
The complete control incorporates plug-in design for easy installation. All flame scanners are minia-
turized. Fireye D30 Series controls directly replace similar Fireye C-Series models.
