MULTI-BURNER
CONTROL
APPROVED
DESCRIPTION
The Fireye Multi-Burner Monitoring System controls the start-up sequence and monitors the flame of
up to 20 individual gas, oil, or combination gas/oil burners connected to a common valve train. Its
dynamic on-board testing checks for faulty relays, proof of valve closure, high and low fire switch
interlocks, and shorted air switch. Exclusive to the unit is its ability to specifically identify which
burner caused the initial flame failure.
The Fireye Multi-Burner Control Monitoring System is a fully integrated control designed for the
industrial process market (ovens and furnaces). It meets the operational requirements and safety stan-
dards pertaining to the industrial process market and offers many advantages over other systems.
The Fireye Multi-Burner Control System is complete with all functions built into one module, offering
the opportunity to greatly reduce cost and space requirements normally required by other non-inte-
grated systems. Plug-in flame sensor modules that can sense UV, UV Self-Check and/or flame rod pro-
vide for easy replacement on an individual basis. Start up time is reduced through the use of on board
DIP switches that allow quick configuration to meet application requirements.
The MB-600S, by itself, provides for 4 plug-in flame sensor modules. Expansion modules are avail-
able that can be easily attached to the MB-600S allowing for a system configuration up to 20 burners.
Upon startup, the MB-600S interrogates the expansion modules to learn the number of flame sensor
modules installed. Refer to the system diagram shown in Fig. 4.
The microcomputer based system features a plug-in modular design so any of the modules attached to
the motherboard can be replaced by shutting down the Multi-Burner Control or the monitored burners.
Its DIP switches allow sequence and timing functions, as well as system configuration. It is also capa-
ble of modulation (high and low fire purging) and monitoring up to four auxiliary inputs, history log-
ging, and interfacing to valve leakage detection devices. It is UL recognized (US and Canada) and FM
approved.

ELECTRICAL RATINGS
VA ratings (not specified as pilot duty) permit the connection of transformers and similar devices
whose inrush current is approximately the same as their running current.
VA Pilot Duty ratings permit the connection of relays, solenoid valves, lamps, etc. whose total oper-
ating load does not exceed the published rating and whose total inrush current does not exceed 10
times the rating.
Running and locked rotor ratings are intended for motors. VA and VA Pilot Duty loads may be
added to a motor load provided the total load does not exceed the published rating.
CAUTION: Published load ratings assume that no contact be required to handle inrush cur-
rent more often than once in 15 seconds. The use of control switches, solenoid, relays, etc.
which chatter will lead to premature failure. 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 of any external current consuming devices.

PRODUCT DESCRIPTION
The Fireye Multi-Burner Control System consists of a motherboard and 3 plug in modules. These
modules are located under the cover attached to the motherboard by 4 type #6-32 X 1/2 in screws. It
will be necessary to remove the cover to access the dip switches located on the logic module.
Relay Module (MB-600R)
The relay module contains the output relays which provide power for operating the ignition coil,
pilot valve, main valve, combustion fan and alarm. This module is mounted in the first position on
the left of the motherboard closest to the output terminals.
COVER RETAINING SCREWS
RELAY MODULE POWER MODULE
LOGIC MODULE
Logic Module (MB-600L)
The logic module houses the microcomputer which provides all the sequential logic and safety start-
up and shutdown circuitry. DIP switches are provided to allow for sequence and timing functions as
well as system configuration. On the front of this module is the reset, scan and enter push-buttons,
and status lights. This module is mounted in the second position from the left of the motherboard
next to the relay module.
Power Module (MB-600P)
The power module supplies the power required for the electronic circuitry. It is mounted in the moth-
erboard to the right of the logic module. The green LED on the front indicates that power is on to the
Multi-Burner Control.
Flame Sensor Module
The Fireye MB-600PF is the flame sensing module
of the Multi-Burner Control. One MB-600PF is
required for each burner in the system. The MB-
600PF modules are installed into the motherboard
by carefully inserting them into the round 11-pin
sockets.
Each MB-600PF is equipped with 2 X 4-40 x 1/2
in. external mounting screws for securing into the
motherboard. On the front of the MB-600PF mod-
ule is a “Flame On” LED, illuminates when a flame
is detected at the corresponding burner. Directly
below the “Flame ON” LED is a “Flame Fail”
LED, which illuminates on flame failure on a first-
out basis, minimizing downtime. The MB-600PF
5
incorporates test point and ground (GND) connection jacks in the front of the unit. Using these, the
flame signal strength of each burner can be measured using a 0-15 VDC, one megohm/volt meter.
Expansion Module
The expansion board contains the mounting sockets and connection ter-
minals for adding additional MB-600PF flame sensing modules, which
is needed for systems having more than four burners.
There are two expansion boards available: one for adding up to four
MB-604E, 4 BURNER
more burners (MB-604E) and one for adding up to eight more burners
EXPANSION BOARD
(MB-608E). For systems monitoring 13 to 20 burners, two of the expan-
sion boards for up to eight more burners are used.
The four burner expansion board CANNOT be used in conjunction with the eight burner expan-
sion board.
A cable, P/N 59-506-1 or 59-506-3, connects either expansion board to
the motherboard (J8 on the motherboard to J2 on the expansion board).
For greater than 13 burners, two 8 module expansion boards are daisy
chained together (J7 on one expansion board to J2 on the other expan-
sion board); see page 16 for terminal strips identification and location.

EXPANSION BOARD
Remote Display
The MB510 remote display provides alphanumeric messages which indicate burner status as well as
annunciate lockout condition in the Multi-Burner Control System. The MB510 also contains a key-
pad used to provide remote reset and access to lockout history
A cable connects the remote display to the motherboard; this cable is available in 6 feet, 59-507-6
and 10 feet, 59-507-10, lengths.
DIP Switch Selection
The Fireye Multi-Burner Control DIP switches allow for sequence and timing functions as well as
system configuration.
DIP Switch Selection
The Fireye Multi-Burner Control Monitoring System provides a series of dip switches that allow
for sequence and timing functions that assist in configuring the system to meet the application
requirement.
Caution: To avoid electric shock, shut off the power supply when installing any control
device. Flame monitoring systems must be installed by a qualified, licensed technician.

The DIP switches are located on the logic module, which is mounted in the second position from the
left on the motherboard next to the relay module.
To gain access to the DIP switches, the cover of the logic
S2 S4
S6
module must be removed. To do this, remove the four screws
ON
which hold the cover onto the motherboard. Then gently pull
the logic module towards you to disengage the logic module
from its mating connector. Located on the outside of the
OFF
cover is a label describing the function of the DIP switches.
For all dip switches, the ON position is toward the top of
the logic board.
WARNING: THE INAPPROPRIATE SELECTION OF DIPSWITCHES COULD RESULT
IN AN UNSAFE CONDITION HAZARDOUS TO LIFE AND PROPERTY. Changing the
dipswitches modifies the operation of the Multi-Burner Control System. Care should be
taken to insure the proper dipswitch settings. Setting the dipswitches for a particular appli-
cation should be made by a competent professional, such as a Boiler/Burner technician
licensed by a state or government agency, engineering personnel of the burner, boiler or fur-
nace manufacturer (OEM) or in the performance of duties based on the information from
the OEM.

FUNCTION SUMMARY
Combustion Air Flow Check Terminal
The Multi-Burner Control checks that the combustion air flow switch is open before start-up, closed
during operation and open again at burner shutdown, thus preventing operation with an air switch
that is defective, maladjusted or jumped.
Main Fuel Valve Proof-of-Closure Terminal
The Multi-Burner Control checks that the main fuel valve is closed before start-up and after burner
shutdown. This arrangement requires an approved proof-of-closure switch on the main fuel valve.
Low Fire Start Terminal
The system checks for the low fire start position prior to light-off.
High Fire/High Fire Purge Check Terminal
When selected, the system checks that the air modulation motor reached the high fire position during
high fire purge. The modulation motor must be fitted with a high fire position switch, which is then
connected to the high fire check terminal. An air flow or pressure switch that is set to prove sufficient
purge air may be used instead of the high fire position switch.
Recycle Mode
When selected, the Multi-Burner Control will restart the sequence after flame or air failure. The
recycle mode allows the system to re-initiate the start-up sequence automatically, once the main
burners have been operating for at least 35 seconds. If the pilot flame fails to light during recycling,
the system will lock out and annunciate a pilot flame fail. If the recycle is successful and the main
burners are operational for at least 35 seconds, the system is ready for another recycle. At no time
will the system recycle in the event of pilot flame fail.
Pilot Test Mode
This mode is entered by depressing the “Reset” and the “Enter” buttons simultaneously then releas-
ing the “Reset” button but holding the “Enter” button for another 10 seconds. The limits light will
flash off and on, indicating that the system is in the test mode. In the pilot test mode, the Multi-
Burner Control operates normally with the exception that the main valves are not energized, prevent-
ing the main burners from igniting. To exit the pilot test mode, simply press the “Reset” button and
the Multi-Burner Control will exit the pilot test mode and restart the sequence.
Interrupted or Intermittent Pilot
Pilot mode is selected using the DIP switch (see “S2 DIP Switch Settings” on page 7). An interrupted
pilot shuts off after the main flame is established. An intermittent pilot continues during the entire
main flame firing cycle.
Spark, Pilot Flame and Main Flame Separation
During the trial for ignition period (TFI), the pilot valve and ignition coil remain energized. At the
end of the TFI, the pilot flame remains on and the ignition coil is de-energized. After a five second
delay to prove the pilot flame, the main gas valve is energized to begin the main trial for ignition.
The times selected with SW3 of S2 and SW7 of S4 apply to both pilot and main trial for ignition.
Note: All pilots must light within the specified TFI or a pilot flame failure will occur.
If one burner experiences either a pilot or main flame failure, then all burners will shut
down. The failed burner will be indicated by the red “Flame Fail” light on the correspond-
ing flame sensor, MB-600PF.
10
SYSTEM FAULTS
A system fault (illuminated by the fault LED on the logic cards) prevents gas ignition but does not
lock out the system. System fault conditions are as follows:
1. If a flame is detected out of sequence, which may be caused by:
a) a faulty scanner
b) electrical interference on the sensor leads
c) a flame exists in the burner due to a gas leak or other condition.
2. Air flow switch closed before start-up.
System Lockout Conditions
A system lockout will occur (illuminated by the alarm LED on the logic card) for any of the follow-
ing conditions:
1. Air failure–loss of combustion anytime during the operational cycle.
2. Pilot flame fail–loss of flame during the trial for pilot ignition period.
3. Main flame fail–loss of flame during the main burner trial for ignition.
4. Main fuel valve–open after cycle shutdown or before start-up with interlocks closed.
5. Unmatched burners–the number of flame sensing modules installed (MB-600PF or
MBPF-100S) does not match the number selected on the DIP switches (see “S6 DIP
Switch Settings” on page 9).
6. Relay fail–failure of Multi-Burner Control internal relays.
7. Low fire fail–low fire switch open prior to trial for ignition.
8. High fire fail–high fire switch is not closed at the end of high fire purge.
9. Flame fail–loss of flame after main flame has been established.
10. If no purge time is set (see “S2 DIP Switch Settings” on page 7).
11. Wiring error which puts external voltage on any of the output terminals.
12. Welded internal contacts or other malfunctions in the Multi-Burner Control.
13. Auxiliary input fail–loss of input voltage to any of the four “AUX” terminals after the limit
input is made.
14. A system fault condition that lasts longer than 30 seconds.
11
Extended Features
High to Low Fire Purge Modulation Capability with High to Low Fire Position Switch Inter-
locks
The modulation feature incorporates a high fire purge time and a low fire start check into the purge
sequence. This feature allows the Multi-Burner Control to sequence internal dry contacts which can
be used by the customer requiring a high fire purge of the combustion chamber before ignition.
The high fire purge time is selectable by means of S2 DIP switches on the logic board (see “S2 DIP
Switch Settings” on page 7):
The modulation terminals on J3 terminal strip will sequence as follows:
Sequence Step Internal Contact Connections - see page 19
High Fire Purge......................... J3,T1 (COMMON) to J3, T3 (HI FIRE)
Low Fire Start............................J3,T1 (COMMON) to J3,T4 (LOW FIRE)
Automatic...................................J3,T1 (COMMON) to J3,T2 (AUTO)
Power Off...................................J3,T1 (COMMON) to J3,T2 (AUTO)
Power On/Limits Off................J3,T1 (COMMON) to J3,T4 (LOW FIRE)
Alarm............................................J3,T1 (COMMON) to J3,T4 (LOW FIRE)
The Automatic step occurs when the burners are operating and allows the burner firing rate to be
controlled by an automatic temperature controller.
Auxiliary Inputs with History Log
This feature provides four auxiliary inputs which are monitored by the Multi-Burner Control as
alarm interlocks. This means that when the input voltage is interrupted, the system locks out and will
annunciate on the optional remote display unit.
Once activated, a voltage of 120 VAC must be present at the input for the Multi-Burner Control Sys-
tem to operate. If an auxiliary input loses its voltage for more than one second while the interlocks
and limits input is powered, then a lockout condition will occur. If the Multi- Flame is equipped with
an optional remote display unit, then the following message will occur:
AUX. INPUT #1 AUX. INPUT #2 AUX. INPUT #3 AUX. INPUT #4
AUX.LIM#1 FAIL AUX.LIM#2 FAIL AUX.LIM#3 FAIL AUX.LIM#4 FAIL
HH:MM:SS LOCKOUT HH:MM:SS LOCKOUT HH:MM:SS LOCKOUT HH:MM:SS LOCKOUT
Unused auxiliary inputs should be connected to 120 VAC.
Valve Leak Sensing Device (VLSD) Interface
The Multi-Burner Control Valve Leak Sensing Device (VLSD) interface is designed for use with a
FIREYE MECHANICAL FMTC410, FMTC310, or FMTC210 Valve Leak Detection device (and is
suitable for use with other, third party Valve Leak Sensing devices) by providing a 120 VAC output
which triggers the start of the test period. An input is also provided which receives a 120 VAC signal
from the VLSD.
If the signal is received within the test period (40 seconds), then the test has been successfully com-
pleted. This option includes the required sequential software to initiate the valve leak test on startup
and shutdown of the burners.
When the limits close to the Multi-Burner Control, the 120 VAC output to the VLSD is activated. If
an optional remote display is connected, the following message will appear:
VALVE LEAKAGE
UNDER TEST XX (where X is the remaining seconds of the test)
12
If the VLSD does not activate the VLSD 120 VAC input within 40 seconds, then an alarm lockout
will occur, and the following message will appear on the optional remote display:
VALVE LEAK FAIL
If a valve leak occurs, then the fan output on the Multi-Burner Control will be activated to purge the
combustion chamber of gases.
If the VLSD input is not used, then it should be connected to 120 VAC.
Remote Display Units
The MB510 Display unit is available with a keypad and keypad allows remote reset and activation of
the history log option. The display module is panel mountable and features a liquid crystal display in
a 1/4 DIN housing.
The MB510 display module connects to the Multi-Burner Control by a 6 or 10 foot cable.
The MB510 display incorporates the following features:
1. Provides status messages for the Multi-Burner Control sequence.
2. Indicates lockout conditions when they occur, as well as the amount of time into the sequence
when the lockout occurred.
3. Provides continuous monitoring of each burner’s flame signal strength during main burner oper-
ation. (Pressing ENTER once will lock on a particular burner’s status; pressing ENTER a sec-
ond time will resume scrolling).
4. Incorporates a remote reset key into front membrane of unit (remote with keypad only).
5. Provides the interface required for the History Log option (remote with keypad only).
6. Incorporates ENTER key for pilot test mode.
History Log Activation
The history log is only accessible through an optional remote display unit with remote reset, and
when the Multi-Burner Control is in a “LOCKOUT” or “LIMITS OPEN” condition. The history log
records the total number of operating cycles, and the last lockout messages up to a maximum of 10.
With a remote display available and the Multi-Burner Control in one of the two conditions described
above, the history log can be accessed as follows:
1. Press and hold the ENTER key on the remote display unit until the following message appears:
TOTAL OPERATING
CYCLES = XXXXX (where X is a digit between 1 and 9)
The record number will display as long as the ENTER key is pressed.
2. Release and press the ENTER key a second time. The record number of the lockout message
will be displayed:
RECORD #X (where X is the number of the most recent lockout)
3. Release the ENTER key and the most recent lockout message will display for seven seconds.
4. To see the next lockout message, press and release the ENTER key before the seven second time
duration ends of the most recent lockout message display. This will prompt the next lockout
message. If desired, continue this procedure until the maximum of ten lockout messages has
been displayed (remember that the highest record number is the most recent lockout message).
5. Continued pressing and releasing of the ENTER key in less than seven seconds keeps the his-
tory log active and repeats the lockout message list; waiting longer than seven seconds deacti-
vates the history log mode and the next display is the last sequence message before the history
log was activated. For example, if the message “LIMITS OPEN” was displayed when the his-
tory log was activated, then that message will appear again after seven seconds.
6. To erase all of the lockout messages from the history log, press the RESET and ENTER keys
simultaneously while the history log is active. Release the RESET key, but hold the ENTER key
for another five seconds.

RS232/RS485 Communication Interfaces
Terminals 5 and 6 on Multi-Burner Control terminal strip J7 provide a serial output communication
interface for remotely monitoring the system sequence and status using a terminal or a modem; refer
to later section for the types of messages sent by the Multi-Burner Control.
The communications protocol is 8 bit, no parity, 1 stop bit and1200 baud. Multi-Burner Control
model MB-632S is provided as a RS232 interface. Multi-Burner Control model MB-685S is pro-
vided as a RS485 interface.
Transmission of messages from the Multi-Burner out the RS232/RS485 interface is turned ON by
default at power up and at the completion of each burner cycle. Transmission of ALL messages out
the RS232/RS485 port can be turned OFF for the remainder of the current burner cycle by sending a
space character (=ASCII Hex 20). Messages can be turned back ON by sending a carriage
return (=ASCII Hex 0D) from the terminal.
Sending a CTRL-E (=ASCII Hex 05) access the optional history log. Each transmission of
CTRL-E acts like the pressing of the ENTER key from the remote display, causing one of the 10
records to be transmitted. See “History Log Activation” section for additional details.
LOGIC MODULE STATUS LIGHTS & PUSH-BUTTONS
The logic module provides all the sequential logic, and safety startup and shutdown circuitry. On the
front of the module is the reset, scan and enter push-buttons, and status lights. This section describes
the their respective functions.
Limits
This LED illuminates when the operation limits are made. These limits are wired
LOGIC MODULE
in series to terminal J1-1. This input becomes energized to begin the burner
sequence. When in the test mode, this LED flashes (see “Pilot Test Mode”).
RESET Air
This LED illuminates when the air switch is closed and power is thereby applied
to the air switch input. The Multi-Burner Control also checks this input for an air
LIMITS switch short (see “Combustion Air Flow Check Terminal”).
Purge
AIR
This LED illuminates whenever the combustion blower is energized, including
PURGE
the purge period and the main burner period of the sequence. It blinks on and off
while the purge is in process and remains constant when the purge process is

SYSTEM INSTALLATION
In this section, the necessary procedures are detailed to integrate a Multi-Burner Control into a
burner system; Figures 5 and 6 illustrate the various terminal strips mentioned followed by suggested
wiring diagrams.
Shut off the power supply before any module is removed or replaced from the unit, including the
remote display.
Caution: Installation and maintenance must conform with the National Electrical Code and
all other national and local codes and authorities having jurisdiction.
POWER SUPPLY
All input power must be single phase 120 VAC, 60 Hz. All circuits must have a common 15 amp fuse
and disconnect. The neutral must be grounded. Do not use solid-state triac output devices in any of
the input circuits. 120 VAC wiring must be at least 90°C 16 AWG minimum and satisfy all applica-
ble codes.
INTERLOCKS AND LIMIT SWITCH INPUT
Interlocks are generally pressure or temperature switches which, when activated, start the burner.
Limit switches are generally pressure, temperature and other switches which, when activated, stop
the burner. The interlocks and limit switches are wired in series. A break in this circuit will shut the
burner down, but will not produce an alarm. This input is considered the normal operation control
input to the Multi-Burner Control System.
COMBUSTION AIR SWITCH INPUT
This input is for monitoring the combustion air switch separately from other interlocks and limits.
When wired to this input, the air switch will be proven open before start-up and after shutdown. It
will also be proven closed 10 seconds after the combustion air blower is energized.
If the air switch opens during the main firing cycle, the system will either lockout or recycle, depend-
ing on the DIP switch selection.
If this terminal is not used, place a jumper between the combustion blower output (terminal 3 on ter-
minal strip J2) and the air switch input (terminal 2 on terminal strip J1).
If the combustion air blower is controlled outside of the Multi-Burner Control System, then the air
switch must be wired between the combustion blower output and the air switch input. Connecting the
air switch in this manner will prevent the open contact (air short) check on the switch.
MAIN VALVE PROOF-OF-CLOSURE
The system can be wired to check for the proof of valve closure (POVC) switch on the main gas
valve prior to start-up and after the end of the burner cycle. To use this feature the POVC switch
must be connected to the POVC switch input (terminal 3 on terminal strip J1). If this feature is not
used, a jumper must be placed between terminals 2 on terminal strip J2 and 3 on terminal strip J1.
IGNITION WIRING
Route ignition wiring a sufficient distance from all sensors and other low voltage wiring to avoid
electrical interference, which may cause erratic operation of the Multi-Burner Control System. Do
not connect multiple ignition coils in excess of output relay contact rating.
LOW FIRE INPUT
It is possible to wire the system for checking low fire start position prior to pilot ignition. To use this
feature, the low fire start switch must be connected to the low fire start input (terminal 4 on terminal
strip J1). If this feature is not used, a jumper must be placed between terminals 1 and 4 on terminal
strip J1.
16
HIGH FIRE INPUT
The system can be wired to check for high fire position during the high fire purge portion of the
sequence. To use this feature, the high fire position switch must be connected to the high fire input
(terminal 5 on terminal strip J1). If this feature is not used, a jumper must be placed between termi-
nals 1 and 5 on terminal strip J1.
EXPANSION BOARDS
There are two different expansion boards available: one for up to four additional burners (MB-604E)
and one for up to eight additional burners (MB-608E). Either expansion board is mounted on the
sub-panel separate from the Multi-Burner Control motherboard. It requires its own power (120 VAC/
60 Hz) connected to L, N, GND on terminal strip J1 (120 VAC to L, neutral to N and GND to
ground).
Note: The four burner expansion board CANNOT be used in conjunction with the eight burner
expansion board.
The connection to the motherboard is made via a cable (59-506-1, -3) which joins two plug connec-
tors at J8 on the motherboard and J2 on the expansion board. The connections between the two plugs
are to matching numbers (i.e., pin 1 on J8 connected to pin 1 on J2). The same two-plug connector
cable is used in systems for 13 to 20 burners where two expansion boards are linked to the mother-
board.
The first expansion board is connected to the motherboard as described above, while J2 of the sec-
ond expansion board is connected to J7 of the first expansion board. Sensor connections are made to
the corresponding flame sensing module at terminals J3 and J4.
REMOTE DISPLAY
When installed, the remote display must be grounded. Panel mounting is through a 1/4 DIN cutout.
Use either the 6 or 10 foot cable to connect it to the motherboard.
REMOTE RESET
This feature permits remote mounting of a switch to reset the Multi-Burner Control. To use this fea-
ture, a normally open remote reset switch must be wired between terminals 1 and 4 of terminal strip
J7. When it is depressed or actuated, an internal optically isolated coupler is fired causing the Multi-
Burner Control to reset. If neither remote reset nor remote LCD display (MB510) is used, and to
improve immunity against possible electrical interface, it is suggested that a jumper be placed
between terminals 1 and 4 on terminal strip J7.
The remote reset input is a low voltage signal circuit that must be routed separately from
other control voltage wiring. Use two conductor shielded cable with the shield connected on
one end only to terminal 1 of J7.
COMMUNICATION WIRING
Route communication wiring a sufficient distance from ignition and other high voltage wiring to
avoid electrical interference.

TEST PROCEDURES
INTRODUCTION
This section describes the test procedures that must be performed after installation to insure that the
Multi-Burner Control is operating properly; these procedures are mandatory.
LIMITS AND INTERLOCK TESTS
Periodically check all interlock and limit switches by manually tripping them during burner opera-
tion to make sure they cause the system to shut down.
WARNING: Never operate a system that is improperly adjusted or has faulty interlocks or
limit switches. Always replace faulty equipment with new equipment before resuming oper-
ation. Operating a system with defective safety equipment can cause explosions, injuries,
and property damage.
— The burner at which a flame fails will be identified by a red “Flame Failure” LED on the corre-
sponding MB-600PF flame sensing module.
FLAME SIGNAL STRENGTH
FIGURE 7.
Voltmeter Hookup to Measure Insert the positive probe of a 0-15 VDC, one megohm/volt
(minimum) meter into the test point on the MB-600PF as
applicable, shown in the photo at left. Connect the negative
probe to ground. A good flame signal strength will read
between 6 and 11 VDC; anything below 4 VDC is inadequate.
MINIMUM PILOT TEST
Run the following test procedures to ensure that the sensor
will not detect a pilot flame too small to reliably light the main
flame:
1.Manually shut off the fuel supply to the burner, but not to the
pilot.
2.Start the system normally.
3.To enter the pilot test mode, press the RESET and ENTER
buttons simultaneously. Then release the RESET button but
keep the ENTER button depressed for another 10 seconds. The
Limits LED will blink, signaling that the system is in the pilot
test mode.
4. The control will hold the operating sequence at the pilot flame step. Measure signal strength as
described above.
5. Reduce pilot fuel until the flame relay drops out. Increase pilot fuel until the flame signal is
greater than 4 VDC, and flame relay just manages to pull in. This is the minimum pilot. If you
don’t think this flame will be able to safely light the main burner, realign the sensor so that it
requires a larger pilot flame and repeat steps 2 through 5.
6. Push the RESET button to exit the test mode and begin the normal start-up sequence again.
7. When the sequence reaches the main flame trial for ignition, smoothly restore the fuel supply to
the burner. If the main burner does not light within five seconds, immediately shut off the burner
supply to shut down the system. Realign the sensor so that it requires a larger pilot flame. Repeat
steps 1 through 6 until the main burner lights off smoothly and reliably.
22
PILOT FLAME FAILURE TEST
1. Manually shut off the fuel supply to one individual pilot and main burner, or all burners if the
system has a single fuel supply.
2. Place system in pilot test mode.
3. Start the system normally. The controller should lock out*; if it doesn’t, then the controller is
detecting a false flame signal. Find the problem and correct it before resuming normal opera-
tion.
4. Repeat steps 1 through 4 until all burners have been tested.
MAIN FLAME FAIULRE TEST (For Interrupted Pilot Systems)
1. Manually shut off the fuel supply to the main burner, or all burners if the system has a single
fuel supply, but not to the pilot.
*
2. Start the system normally. This should ignite the pilot and lock out after pilot interruption. If
the system does not lock out, the controller is detecting a false flame signal. Locate the problem
and correct it before resuming normal operation.
3. Repeat steps 1 through 3 until all burners have been tested.
SPARK SIGHTING TEST
1. Manually shut off the fuel supply to the pilot and main burner.
2. Start the system normally.
3. Measure the flame signal as described in “Flame Signal Strength” in this section.
4. If a flame signal greater than 4 VDC is measured for more than three seconds during the trial for
ignition, then the sensor is picking up a signal from the spark plug. Refer to Sensor Installation.
SENSOR INSTALLATION
WARNING: Incorrect sensor installation may cause the sensor to generate a false flame sig-
nal, causing unburned fuel to collect in the combustion chamber. The result can be explo-
sions, injuries and property damage. Be certain that the flame sensor detects only pilot and
main flames, not glowing refractory, burner or ignition parts.
SENSOR WIRING
Route sensor wiring a sufficient distance from ignition and other high voltage or high current wiring
to avoid electrical interference. Interference from ground currents, nearby conductors,
radio-frequency emitters (wireless devices), and inverter drives can induce false flame signals.
Shielded cables can help reduce interference with the shield connected to ground at the control end
only. The wire type and its capacitance (picofarads or microfarads) to ground may cause low signal
problems, so a grounded shield may decrease the signal due to the cable’s internal capacitance.
Multiple UV tube-type sensor leads run together without shielding may interfere or “cross talk”, so
the shield or flexible armor must be grounded to prevent this situation. For flame rod sensor runs
approximately 100 feet (30 meters) or greater, use Belden P/N 8254-RG62 coax cable. To achieve
the maximum wiring distance, the shield should not be grounded (keep in mind that an underground
shield provides less protection against electrical interference). Depending on field connections,
sensor wiring can be up to 200 feet (61 meters).
Do not ground the shield to terminal GND.
Unshielded sensor wiring must not be run in common with other wires; it must be run in separate
conduit. Multiple flame sensor wiring must not be run together in a common conduit or wireway.
Use #14 to #18 AWG wire suitable for 90°C (194°F) and 600 volt insulation, and run each pair of
23
leads in its own shielded cable. Multiple shielded cables can be run in a common conduit.
*
The burner at which a flame fails will be identified by a flashing red “FLAME FAIL” LED on the corresponding flame sensing module.
24
FLAME RODS
Flame rods should be used only on gas burners. They accu-
mulate soot on oil burners, causing nuisance shutdowns and
unsafe operating conditions. See the burner manufacturer’s
literature for flame rod mounting location. When installing
FLAME ROD
flame rods, please consider the following:
1.Keep the flame rod as short as possible and at least 13
WRONG
CORRECT
mm (1/2") away from any refractory.
Rod Detects
Rod Detects
Weak Pilot
Only Strong
2.Position the rod into the side of both the pilot and main
Pilot Flame
flames, preferably at a descending angle to minimize
drooping of the flame rod against burner parts, as shown at
left. Flame rod position must adequately detect the pilot
flame at all burner draft conditions. Extend the rod 13 mm
(1/2") into nonluminous flames, such as blue flames from
burning an air/gas mixture. For partially luminous flames,
such as atmospheric air/gas mixtures, place the rod at the
edge of the flame.
3. Provide a burner/flame grounding area that is at least four times greater than the flame rod area
contacting the flame. The flame rod/burner ground ratio and position of the rod in the flame may
need adjustment to yield maximum flame signal strength.
4. Ignition interference from the spark plug may increase or decrease the flame signal strength.
Reversing the ignition transformer primary leads may reverse this effect. Reducing the spark
gap or adding grounding area between the flame rod and spark plug may eliminate the interfer-
ence.
SCANNERS
Use only Fireye scanner models UV7A4, UV7R4 &
UV7SC. Consult the burner manufacturer’s instruc-
tions for mounting location. When installing scanners,
please consider the following:
UV SCANNER
(MODEL UV7A4)
1.Position the scanner within 457 mm (18") of the
flame.
2.Bushing threads are 1/2 inch F.N.P.T. for scanner
models UV7A4 and UV7R4; model UV7SC has 1 inch
F.N.P.T. bushing threads.
90° UV SCANNER
3.The ambient temperature limits of each scanner var-
(MODEL UV7R4)
ies; check the literature supplied with the scanner. For
higher temperatures, use Fireye heat insulator part
number 35-319. If necessary, also use a purge tee.
4.An optional magnifying lens (Fireye P/N 46-185)
may also be used to increase the flame signal strength
in difficult sighting situations.
SELF-CHECK UV SCANNER
(MODEL UV7SC)

shutdowns during burner ignition. If necessary, use a scanner
orifice to reduce spark pickup.
2.Do not allow the scanner to detect a pilot flame that is too
small to ignite the main burner.
3. Perform a minimum pilot test when installing or adjusting any pilot or main burner system; see
“Minimum Pilot Test” on page 22.
