Brahma 18047053 TGRD71 control box

Brahma TGRD71 is a high-tech microprocessor combustion manager from the KOMPACT series, designed for full automation of ignition, flame monitoring and safety of atmospheric gas and liquid fuel (diesel) burners operating in intermittent mode. The device is equally effective with or without a fan in the combustion circuit. Model TGRD71 (art. 18047053) is a direct analogue of 18047051 and is widely used in Master air heaters (spare part code 4033.017) and other heat generating equipment, for example: diesel air heaters Master BV 77, BV 69, RV 55, EC 22, EC 32, GE 36, GE 46; gas and diesel heating boilers; hot air generators; radiant tube and convector heaters; burners Riello, Weishaupt, Lamborghini, etc. Main functions and features Built-in high-voltage ignition transformer: TGRD71 combines a programmable controller and a powerful ignition system, simplifying the burner design and reducing the number of external components. Programmable time parameters: The controller has preset times: pre-purge (TP) = 20 seconds, safety time (TS) = 5 seconds (parameters indicated on the housing). This allows adaptation to most burners. Non-volatile lockout and manual reset: In any emergency (flame absence, ignition failure, etc.) the unit goes into lockout state. Restart is only possible manually — by pressing the Reset button after eliminating the fault. This prevents automatic restart and meets the highest safety class. Flame monitoring: Supports ionization electrode and photodiode. Reaction time to flame loss is less than 1 second. Dual shutdown path and self-diagnostics: The system is equipped with two independent
