Brahma Microprocessor controller TGR1 18047952

The Brahma TGR1 (SKU 18047952) is a microprocessor-based control box for automatic ignition control, flame monitoring, and safe operation of atmospheric gas burners, supporting both single-stage and two-stage types. It operates in an intermittent cycle and is suitable for burners with natural draft or forced air supply. The device uses ionization flame detection and complies with EN 298 standards. It performs a sequence including false flame check, pre-purge, ignition, flame monitoring, and safe shutdown upon flame loss, with a reaction time of less than 1 second. Manual reset lockout occurs in abnormal situations such as flame loss or ignition failure.

Parts of this type are selected by matching the exact series and type designation, supply voltage, safety and pre-purge times, and flame detection method (ionisation, UV, or IR). The physical connection pattern (base or plug) must also correspond. Before ordering, verify the pre-purge time (tv), safety time (ts), and wait time (tw) values indicated on the unit housing against the requirements of your burner. Controls from different series are normally not interchangeable, and mismatched safety times create a safety hazard.

Common failure modes for this kind of control include failure to ignite, lockout without restart, or intermittent shutdowns. When a control fails, the burner may not start, or it may shut down during operation and require manual reset. Check for loose connections, damaged ionization electrode, or incorrect supply voltage. If the control goes into lockout repeatedly, verify the flame detection circuit and safety interlocks.
