Brahma 18047051 TGRD71 control box

Brahma TGRD71 is a high-tech microprocessor combustion manager from the KOMPACT series, designed for full automation of ignition processes, flame monitoring and safety of atmospheric gas and liquid fuel (diesel) burners in intermittent operation. The device is equally effective with or without a fan in the combustion circuit. This controller can be used in a wide range of industrial and domestic heating equipment: heating, combined and steam boilers; air heaters (including diesel Master series BV 77, BV 69, RV 55, EC 22, EC 32, GE 36, GE 46 per spare part code 4033.017); hot air generators; radiant tube and convector heaters; water heaters, industrial furnaces, monoblock burners. Main functions and features Built-in high-efficiency electronic ignition transformer: TGRD71 combines a combustion manager and a powerful ignition system, significantly simplifying the burner design and reducing the number of external components. Programmable time parameters: The controller allows flexible adjustment of pre-purge time (TP = 20 seconds) and safety time (TS = 5 seconds), adapting operation to a specific burner. Exact parameters are always indicated on the unit housing label. Non-volatile lockout and manual reset: In an emergency (flame absence, ignition failure, etc.) the controller goes into lockout state, and restart is only possible manually by pressing the reset button on the housing. This prevents automatic restart of the burner when the fault is not eliminated. Flame monitoring: Flame detection via ionization electrode or photodiode, providing instant reaction to flame loss — less than 1 second. Dual shutdown path
