DESCRIPTION
FIREYE® Series D40-41 Burner Management Controls provide ignition and flame failure protection
for manually started oil or gas burners. Plug-in Amplifier Modules permit the selection of ultraviolet,
repetitive self-check ultra-violet, AUTOCHECK infrared, or rectification methods of flame detection.
The control system includes a safe start check, effective on each start. If flame signal (real or simulated)
is detected, the unit cannot be started. For increased safety and reliability, Fireye 72D1R3 AU-
TOCHECK infrared amplifier (using the pulsing flame signal) and 72DUVS ultraviolet amplifier
(using a scanner shutter) check the function of the flame detecting system for component failure during
each burner firing cycle. Meter test jacks on each amplifier module provide flame signal readout with a DC
voltmeter. Flame failure response time is four seconds (max.). When amplifier modules with T suffix are
used, the flame failure response time is reduced to one second (max.).
The control provides three SPDT and one SPNO load switches for external loads and starting circuits.
Fireye D40-41 Burner Management controls may be adapted to a simple control system or as a building
block with auxiliary devices to provide additional functions.

Page 2: Ordering Information
— Amplifier 72DRT1T Control 70D40 with Amplifier 72DUV1 will also replace a Fireye Type 25DU4 model 5040 provided the wiring is changed to the appropriate wiring shown later in this document. Note: When a C-Series unit is replaced with a D-Series unit, the chassis retaining clip (for a quarter turn fastener) in the wiring base must be replaced with a threaded clip that is supplied with each D- Series Control. - Page 3 ® DESCRIPTION OF FIREYE SERIES D40-41 COMPONENTS Control Chassis and Cover Amplifier Flame Scanner Rectification 45CM1-1000 Photocell w/filter. 72DRT1 2-4 sec.

® INSTALLATION CAUTION: Installer must be a trained safety control technician. Verify that Electrical Power is disconnected before starting installation. Follow the burner manufacturer’s instructions, if supplied. Otherwise proceed as follows. Wiring Base Mount the control wiring base on the burner or on a panel. The location should be free from excessive vibration and within the specified ambient temperature rating. -
Page 5: Installing The Control
Select a scanner location that will remain within the ambient temperature limits of the UV Scan- ner (UV1, UV2; 200°F, 94°C: 45UV5; 135°F, 65°C). If cooling is required, use an insulating coupling (Fireye #35-69 for UV1, UV2 Scanners, #35-127-1 for 45UV5) to reduce conducted heat. - Page 6 ″ x ″ bushing on UV2 installations. coupling.

flame failure occurs. INSTALLATION TESTING Testing Fireye D40-41 controls is accomplished with the use of an AC-DC test meter with 1,000 ohm/ volt input impedance, or a digital meter with 500K input impedance or greater. Test points are located on the chassis board to assist with measuring line and load voltages. -
