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.
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
