Fireye MBCE-110FR-1 User manual

© 2023 Carrier 1
DESCRIPTION
The MBCE-110/230FR modules provide visual indication and electrical outputs that
signal the user regarding flame presence in a combustion chamber. The module uses
Fireye flame rods to sense flame presence independently or as components in a burner
management system. Many operational characteristics are provided including:
•CE approved
•Self-contained: 110 VAC, 50/60 Hz: MBCE-110FR-1, MBCE-110FR-3
230 VAC, 50/60 Hz: MBCE-230FR-1, MBCE-230FR-3
•Flame Rod compatible
•Flame ON/OFF LED indicator
•4-20mA permits direct reading of flame signal strength
•Uses CE approved 11-pin relay base
•Panel surface or DIN-rail mounting
•Self-check
The unit provides a cost effective, self-checking method of monitoring flames using
the ionization principle.
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-110/230FR 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 checks, valve closure, starting and running interlocks, safety timings, etc.).
WARNING: 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
described 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.
NOTICE: When Fireye products are combined with equipment manufactured by others and/ 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.

4. Shall use cable glands or conduit entry devices rated for the application to maintain the
explosion protection and IP rating.
5. The MBCE flame sensors are not repairable. If repairs are required, consult the manufacturer.
Note: The MBCE-110FR & MBCE-110FR have been evaluated to EN 298:2012 by TUV, and

SENSOR INSTALLATION
WARNING: Incorrect flame rod installation may 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 flame rod detects only pilot
and/or main flames.
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 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 leads in its own shielded
cable. Multiple shielded cables can be run in a common conduit.
Flame rods are recommended to be used on gas burners. They accumulate soot on oil burners, causing
nuisance shutdowns and unsafe operating conditions.
See the burner manufacturer's literature for flame rod mounting location.
INDICATION LEDS
The CE Flameswitch contains two bi-color LEDs that are used to provide flame status and alarm
condition per the following table.
LEDs can be viewed through the cutout located on the top side of the unit.

Any equipment connected to the 4-20 mA current loops shall be insulated from hazardous live
parts by protective separation (e.g., double, or reinforced insulation according to DIN EN
61010, DIN EN 50178, DIN EN 60730-1 or DIN EN 60950).
FLAME SIGNAL STRENGTH vs. 4-20mA OUTPUT

4-20mA measurements can be taken from the test jack connector located at the faceplate of the
unit. Measurements can also be taken using the dedicated 4-20mA OUT & 4-20mA COM
terminals located at the wiring base.
NOTE: The 4-20mA return path is labeled “GND” on the faceplate. This is simply a local return
path for the 4-20mA current, and it MUST NOT be attached or referenced to earth ground or other
forms of ground connection. Likewise, 4-20mA COM is the return path at the wiring base and
MUST NOT be attached or referenced to earth ground or other forms of ground connection.
SPECIAL CONDITIONS OF USE
1. The equipment shall be installed in compliance with the enclosure, mounting spacing and segregation requirements
of the ultimate application.
2. Line voltage and extra-low voltage wiring to and from this device is intended to be wired in the field to become
part of a Class 1 circuit only.
