DESCRIPTION

Fireye Series D10-20 Burner Management controls provide ignition and main ﬂame failure protec-

tion for automatically ignited oil and gas burners. In conjunction with limit-operating controls and

interlock devices, it automatically programs with solid state timing logic, the burner/blower motor,

ignition, main fuel valve(s) and ﬁring rate motor. The control cycles automatically when the operat-

ing control closes and also 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. An open damper

prepurge and subsequent proof of the low ﬁre position of the ﬁring rate motor before ignition occurs

at each start up. Terminals are provided for a main fuel valve proof of closure interlock which must

be closed before startup and during the prepurge. An interlock circuit is provided for airﬂow

switches, fuel pressure switches etc. which must be closed during the prepurge and ﬁring period.

Control type 70D10 will initiate a safety lockout if this circuit opens during the prepurge, ignition or

ﬁring period. Control 70D20 will recycle and initiate a complete restart if this circuit opens during

the prepurge, ignition or ﬁring period.

The control system is designed to deenergize all fuel valves within 4 four seconds following ﬂame

failure. An alarm circuit actuates audible and visual alarms after a safety lockout. Plug-in ampliﬁer

modules permit the selection of Ultraviolet, repetitive self-check Ultraviolet, "AUTOCHECK" infra-

red, or Rectiﬁcation methods of ﬂame detection. For increased safety and reliability, 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. An optional spark cutoff model is available. A test

switch permits the operator to stop the startup programming before energizing the main fuel valves,

for test purposes.

15 seconds. The use of control switches, solenoids, relays, etc. which chatter will lead to premature failure of switches in the Fireye control. Similarly the contacts cannot be expected to handle short circuit currents without damage. It is important to run through a test operation (with fuel shut off) following the tripping of a circuit breaker, a blown fuse or any known instance of chattering.
Page 6: Installing The Control
® Disconnect the neutral wire (L2) from the control system at the power source. Clip one meter test lead to the grounded green terminal on the lower right side of the wiring base and with the other probe touch each other terminal. At no time should the meter read other than inﬁnity. Reconnect the neutral wire (L2) at the power source.
Page 7 30 inches, closer if possible. Select a scanner location that will remain within the ambient temperature limits of the UV Scan- ner. If cooling is required, use an insulating coupling (Fireye #35-69 for UVI, UV2 Scanners, #35-127-1 for 45UV5) to reduce conducted heat.
Page 8 ® Wiring—UV Scanners To connect the scanner to the control, the UVI Scanner is supplied with 36" or 72" of ﬂexible cable. The UV2 with 36" of ﬂexible cable. The 45UV5-1009 is supplied with four 72" lead wires. Install them in a suitable length of ﬂexible armor cable and connect it to the control. A conduit connector is supplied with the scanner.

INSTALLATION—45CM1 PHOTOCELL MOUNT The 45CMI photocell mount with #922 photocell and Rajah stud terminal, is designed for use in the blast tube on conventional atomizing oil burners.

Page 11 Programmer 71D70 deenergizes the spark ignition after 5 seconds, when connected to Term. 5. When the pilot ﬂame is proven, the “Fireye” indicator (LED) lights. Following a 10 second proven pilot stabilization period, the main fuel valve(s) (Terminal 7) is energized.
Page 12 ® Note: If the main fuel valve interlock is not closed at the start, the control will not initiate a start up— (70D10 will lock out).If it opens during the prepurge—and remains open, the programming sequence will not proceed. The burner/blower motor will be deenergized in 15 seconds. Safety Shutdown Control D10.
Page 13 ® Non-Recycle - With the Dl0 unit, limit switches may be connected in the circuit between Terminals 3 and P. If a limit switch opens during the trial for ignition or ﬁring period, all fuel valves will be deenergized and the control will lockout on safety. If the limit switch opens momentarily during the prepurge period and recloses, the purge period will be extended for the amount of time the switch was open.
Page 14 The function of the low ﬁre start and high ﬁre purge interlock circuits internally in a new Fireye 70D10 unit is accomplished by highly reliable solid state electronic cir- cuitry. This prohibits the connection of power consuming devices (i.e. lamps, annun- ciators, relays, timers, etc.) to the D or 8 terminals.
Page 15: Installation Testing
5 volts 20-25 volts Note: The Fireye 45UV5-1009 is a repetitive self-check scanner that contains a highly reliable shut- ter that closes every 4 seconds to initiate a system check. When the shutter closes, the test jack volt- age should go down to approximately zero, and then back to the normal reading in about 2 seconds.
Page 16 Place the “check-run” switch in the “check” position. Turn power on and initiate a normal start-up. Reduce the fuel supply to the pilot until the “Fireye” light goes out. (If a test meter is used, the DC test jack voltage will be below 5 volts.) Slowly increase the fuel to the pilot until the DC test jack voltage reads about 16-20 volts.

Trouble with installations equipped with Fireye 70D10, 70D20 Controls can be readily iso- lated by following the procedure in the sequence listed below.

Page 19 — Broken wire, loose connection or wiring error. — Bent tab on bottom of control. — Replace 70D series control. Pilot ﬂame lights, but is not detected. “Blower” and “TFI” indicators on, “Fireye” indicator off. (No test jack voltage) — Scanner does not see adequate pilot ﬂame.
Page 20 — Gas pilot valve stuck open. — Wiring error. — Replace 70D series control. Firing rate motor does not respond to demand at end of main ﬂame “TFI”. “Blower,” “Fireye,” “Auto” indicators on — Potentiometer controller set too low or in manual mode.
Page 21: Maintenance
Ampliﬁer will forewarn of any deterioration in the capability of the ﬂame detector or its application. Contacts: There are no accessible contacts in the Fireye D10, D20 D Series Controls. Where con- tacts are used, their design assures long trouble-free life when the load circuits are maintained within the published load ratings.
