DESCRIPTION
The MBCE-110/230UV modules provide visual indication and electrical outputs that
signal the user regarding flame presence in a combustion chamber. The module uses
Fireye UV scanners to sense flame presence independently or as components in a
burner management system. Many operational characteristics are provided including:
• CE certified
• Self-contained: 110 VAC, 50/60 Hz: MBCE-110UV-1, MBCE-110UV-2
MBCE-110UV-3, MBCE-110UV-4
230 VAC, 50/60 Hz: MBCE-230UV-1, MBCE-230UV-3
• UV scanner compatible*
• Flame ON/OFF LED indicator
• 4-20mA output permits direct reading of flame signal strength
• Uses CE certified 11-pin relay base
• Panel surface or DIN-rail mounting
• Flame pull-in threshold adjustment
The module provides a cost effective method of monitoring flames using UV sensing.
The MBCE-UV is intended for non-permanent operation (burner must be recycled at
least once every 24 hours). The MBCE-UV is ideally suited for flame detection in nat-
ural gas applications; however, it can be used for flame detection in propane and light
fuel oil applications.
Check with Fireye for more details by contacting your local distributor or by check-
ing the Fireye home page at: www.fireye.com.
NOTE: When the MBCE-110/230UV modules are used, additional means must be furnished to provide
those functions usually provided by flame safeguard control systems to meet local regulations (i.e.:
safe start check, valve closure, starting and running interlocks, safety timings, etc.).
The MBCE-UV shall be powered continuously from a separate source other than the Burner control
per EN 298. * see ordering information

or integrated into systems designed or manufactured by others, the Fireye warranty, as stated
in its General Terms and Conditions of Sale, pertains only to the Fireye products and not to any
other equipment or to the combined system or its overall performance.

NOTICE: The MBCE-UV is designed to be used with a compatible UV scanner in order to sense
the flame activity in a combustion chamber. The MBCE-UV is not designed to replace a burner
control system, and it cannot assume the responsibilities of a burner control system, including
burner safe start check.
NOTICE: Consult national or local codes for proper selection of the MBCE-UV modules. Some
codes require that the flame failure detection time should not be greater than 1 second.
WA R N I N G : The equipment described in this manual is capable of causing property damage, severe
injury, or death. It is the responsibility of the owner or operator to ensure that the equipment is
installed, operated and commissioned in compliance with the requirements of all national and local
legislation, which may prevail.
Installation, commissioning or adjustment of this product MUST be carried out by suitably trained
engineer or personnel qualified by training or experience.

FLAME SCANNERS
INSTALLATION - UV SCANNERS
Where possible, obtain the burner manufacturer’s instructions for mounting the UV scanner. This
information is available for most standard burners. The UV scanner mounting must comply with the
following general instructions:
1. Position the UV1AL, UV5, or UV90L scanner within 30 inches of the flame to be monitored.
2. Select a scanner location that remains within the ambient temperature limits of the UV Scanner.
If cooling is required, use an insulating coupling (Fireye #35-69 for UV1AL to reduce con-
ducted heat).
3. The UVlAL Scanner is designed to seal off the sight pipe up to 1 PSI pressure. Higher furnace
pressures must be sealed off. To seal off positive furnace pressure up to 100 PSI for UV1AL
Scanner, install a quartz window coupling (#60-1257). Add cooling air to reduce the scanner
sight pipe temperature.
4. Install the scanner on a standard NPT pipe (UV1AL) whose position is rigidly fixed. If the scan-
ner mounting pipe sights through the refractory, do not extend it more than halfway through.
Swivel flanges are available if desired (#60-302 for UV1AL) . The sight pipe must permit an
unobstructed view of the pilot and/or main flame. Both pilot and main flames must completely
cover the scanner field of view
FIGURE 1. AIMING YOUR SCANNER.
5. Smoke or unburned combustion gases absorb ultraviolet energy. On installations with negative
pressure combustion chambers, a small hole drilled in the UV1AL sight pipe keeps the pipe
clean and free from smoke. For positive pressure furnaces, provide clean air to pressurize the
sight pipe, if necessary.
6. To increase scanner sensitivity with UV1AL, use a union with quartz lens (Fireye #60-1290).
This should facilitate the location of the scanner at twice the normal distance. Use l/2" x 1 l/2"
pipe nipple between UV1AL Scanner and the coupling.
7. Request the assistance of any Fireye field office for recommendations of a proper scanner instal-
lation on a non-standard application.
UV90L-1 UV1AL UV5-1
CAUTION: The UV90L-1, UV1AL, and UV5-1 flame scanners are non-self checking UV
sensors. Use these only on burners that cycle often (e.g.: a minimum of once every 24 hours)
in order for the external safety checking circuit to be exercised.

FIGURE 2. TYPICAL SCANNER INSTALLATIONS
WIRING - UV SCANNERS
To connect the scanner to the control, the UV1AL Scanner is supplied with 36"(.9m) or 72" (1.8m)
of cable. The UV5-1 scanner is supplied with an 80” (2m) cable. The UV90L-1 provides field wire-
able terminal block.
If it is necessary to extend the scanner wiring, the following instructions apply:
Scanner wires should be installed in a separate conduit. The wires from several scanners may be
installed in a common conduit.
1. Selection of Wire
a. Wiring: For extended scanner wiring up to 500 feet, and for shorter lengths to reduce signal
loss, use a shielded wire (Belden 8254-RG62 coaxial cable, or equal) for each scanner wire of
UV1AL. The ends of the shielding must be taped and not grounded.
b. Asbestos insulated wire should be avoided.
c. Multiconductor cable is not recommended without prior factory approval.
2. High voltage ignition wiring should not be installed in the same conduit with flame detector
wires.
The maximum UV signal
from a flame is found in the
first one-third of the visible
flame taken from the point
where the flame begins. The
scanner sight pipe should be
aimed at this area.

WARNING: Incorrect MBCE-UV scanner installation can result in the generation of a false
flame signal, causing unburned fuel to collect in the combustion chamber. The result can be
explosions, injuries and property damage. Be certain that the UV scanner detects only pilot
and/or main flames.

3. Route scanner 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.
In some applications 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 can decrease the signal due to the
cable's internal capacitance. Multiple sensor leads run together without shielding may cause
interference or “cross talk”, so the shield or flexible armor must be grounded to prevent this sit-
uation.
THRESHOLD ADJUSTMENT
The MBCE-UV module is equipped with a flame pull-in threshold adjustment capability. This fea-
ture allows the user to dial in the appropriate flame signal threshold for the internal flame relay to
engage. When set, the flame signal strength must be greater than the threshold before the MBCE-UV
can signal "FLAME ON".
The adjustment can be made at the front faceplate potentiometer with the aid of a small flat blade
screwdriver. A clockwise adjustment of the potentiometer decreases the flame pull-in threshold of
the MBCE-UV module allowing the MBCE to pull-in at “small” flame conditions. Likewise, a
counter-clockwise adjustment of the potentiometer increases the flame pull-in threshold of the
MBCE-UV module allowing the MBCE to pull-in at “big” flame conditions. The 4-20mA output of
the MBCE-UV module signals 5.5mA at the pull-in threshold.
