BC-R35 Series
Burner Controllers
Summary
BC-R35 Series burner controllers are combustion safety
controllers specifically designed for batch operation
(systems which start and stop at least once within 24 hours). They
ensure safety by automatically controlling the ignition,
combustion monitoring, and fuel shutoff of oil and gas
burners with proportional control. They are also equipped with
a 7-segment display that can be used in maintenance, a trial
operation mode that is convenient for trial-run operation
and adjustment, and other features.
Add i t iona l l y, t he BC - R35 i s equ ipped w i t h host
communications (RS-485) and Smart Loader Package
functions, allowing troubleshooting and more detailed
observation ofstatus.
Features
Compliant with JIS standards
• Safeconstruction ofcombustion systems andequipment
- Pre-purge and ignition timing in compliance with JIS B
8407:2012 (forced-air burners) and JIS B 8415:2008
(combustion equipment in compliance with the safety
principles for industrial incinerators).
- POC (proof of closure), based on shutoff valve closure
confirmation switch input
• JIS-compliant burner controller safety design
- Safety design in compliance with JIS C 9730 (automatic
electricalcontrols forhouseholdandsimilaruse)
- EN 298 compliance (certification pending)
Easy mounting and replacement
• DIN rail mounting
- Easily mountable inthe same way asother control
devices and controlrelays
• Uses sub-base structure
- Structure separates the sub-base from the main unit It is
possible to change only the main unit, leaving the wired-in
sub-base inplace
Precautionsonequipmentinstrumentation
Extensive communications with external devices
• Equipped with a 7-segment display
- 7-segment display for sequence codes and warning
codes
- Pressthe DISP switchtodisplay the flame voltage.
• External status output
- States such as ignition failure, flame failure, and
combustiondetectedareoutputdigitally(andusedas
panel displays)
• Warning reset by contactinput
• Equipped with a trial-run operation mode
- Thecontrolmotorcanbeforcedtofullopenandfull closed
outputs toadjustthehigh and lowfire positions and check
the airflow volume
• Equipped with host communications (RS-485), allowing
remote observation ofstatus
• Status checking by the Smart Loader Package
(1) Theequipment used inthe combustion safety system was designed with careful consideration oflaws,standards, safety guidelines, and
the like. If the system is designed to a foreign specification, refer to laws and standards in the relevant country.
Main Safety Policies in Japan
- TechnicalpolicyonSafetyStandardsforCombustionEquipmentinIndustrial Furnaces: Ministry ofHealth,LabourandWelfare
- Combustion equipment in compliance with the safety principles for industrial incinerators - JIS B 8415
- ForcedDraughtBurners-Part 1: GasBurners-JISB8407-1
- ForcedDraughtBurners-Part2:OilBurners-JISB 8407-2

Check the operation of the system on installation.
(4) A reset signal must always be input near the equipment (burner, etc.), not remotely.
If a reset is input while it is not possible to confirm safety, there is the risk of explosion.
