1 No. CP-SS-1885E BC-R10 Series Burner Controllers Summary BC-R10 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 burners. BC-R10 burner controllers can be used with AFD100/110 series visible light flame detectors. They are also equipped with a 7-segment display that can be used in maintenance, a trial operation mode that is convenient for trial operation and adjustment, and other features. Features Compliant with JIS standards Safe construction of combustion systems and equipment - Uses prepurge 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) JIS-compliant burner controller safety design - Safety design in compliance with JIS C 9730 (automatic electrical controls for household and similar use) - EN 298 compliance (certification pending) Easy mounting and replacement DIN rail mounting - Easily mountable in the same way as other control devices and control relays Uses a 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 in place Precautions on equipment instrumentation Extensive communications with external devices Equipped with a 7-segment display - 7-segment display for sequence codes and warning codes - Press the DISP switch to display the flame voltage. External status output - States such as ignition failure, flame failure, and combustion detected are output digitally (and used as panel displays) Warning reset by contact input (1) The equipment used in the combustion safety system was designed with careful consideration of laws, 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 Standards in Japan - Technical Policy on Safety Standards for Equipment in Industrial Furnaces: Ministry of Health, Labour and Welfare - equipment in compliance with the safety principles for industrial incinerators - JIS B Forced Draught Burners - Part 1: Gas Burners - JIS B Forced Draught Burners - Part 2: Oil Burners - JIS B The index of safety technology of industrial gas combustion equipment: Japan Gas Association - Index of safety technology of gas boiler combustion facilities: Japan Gas Association (2) This device monitors for failures in the relay contacts used for combustion load (IG, PV, MV) output. An E09 error is output if a voltage occurs at a load terminal, due to a ground fault or wiring error, when this device is not outputting a load. If an E09 error occurs when this device is installed, recheck the wiring and eliminate the factors causing the error. (3) If the wiring from this device exceeds the recommended length, prevent malfunction due to the effects of external noise by running wires from the control panel to the casing through a conduit, keeping a distance between power lines and input lines, and other measures. 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. 1

15 Trial-run operation mode Warning In trial operation mode, loads (blower, ignition transformer, control motor, etc.) operate. They should be operated by a person with expert knowledge and an understanding of the functions. There is a risk of a major accident. Transition to trial operation mode [1] Press and hold the DISP switch for approximately 5 s or more during the stop sequence (when the start switch is Off). The 7-segment display changes to [ C2 ] and the system goes into trial operation mode. The central dot of the 7-segment display starts blinking (a 1 s cycle). [1] [2] [3] [4] [3] Trial operation setup [2] Each time the DISP switch is pressed, the display changes through the cycle [ C2 C3 C4 C5 C6 ] Display C2 C3 C4 C5 C6, flame, ignition failure, flame failure, lockout interlock Blower motor output Meaning n Trial-run operation mode selection [3] Select trial operation type using the DISP switch. When C2 ~ C6 is selected 1 Press the button to enter selection mode. The 7-segment display displays [ Cx/OF ]. 2 When the DISP switch is pressed in this situation, the display toggles between [ Cx/ OF ] and [ Cx/On ], and trial operation runs according to the On/Off selection. * C6 only becomes [ C6/On ]. To turn the blower off, press the switch when in this state. 3 When the switch is pressed to stop trial operation, the display for selecting types of trial operation ([2] above) is displayed. Exit [4] Press and hold the DISP switch for 5 s or more to end trial operation mode. Trial operation mode also ends in the following situations. The power supply is turned Off. 1.1 Forced output of the Flame monitor output ( c2 ) Allows checking of indicators etc. connected to the monitor output terminal. Turns the flame monitor output ON or OFF. 1.2 Forced ignition failure monitor output ( c3 ) Allows checking of indicators etc. connected to the monitor output terminal. Turns the ignition failure monitor output ON or OFF. 1.3 Forced flame failure monitor output ( c4 ) Allows checking of indicators etc. connected to the monitor output terminal. Turns the flame failure monitor output ON or OFF. 1.4 Forced lockout interlock monitor output ( c5 ) Allows checking of indicators etc. connected to the monitor output terminal. Turns the lockout interlock monitor output ON or OFF. 1.5 output On ( c6 ) This is a function to force blower motor (electromagnetic breaker) output and check the air volume. 15
