Brahma Microprocessor-based controller BT2310 18049401

The Brahma BT2310 is a microprocessor-based controller for automatic ignition control, flame monitoring, and safe operation of forced-draught gas, oil, and combination burners. It operates on 24 V DC supply voltage and supports single-stage and two-stage burners. The controller features a pre-purge time of 10 seconds, a safety time of 10 seconds, and a flame loss reaction time of less than 1 second. It uses an ionisation electrode for flame detection, with additional support for UV and photodiode methods. The device has a non-volatile lockout with manual reset, two safety contacts, and is rated IP00. It weighs 0.27 kg and measures 90 x 85 x 65 mm, with an ambient temperature range of -20 to 70 °C. It complies with EN298:2003 and is designed for intermittent operation with a service life of 250,000 cycles under maximum load.

Parts of this type are selected by matching the supply voltage, safety time, pre-purge time, and flame detection method to the burner's requirements. The controller must be compatible with the burner's fuel type and stage configuration. Installation involves mounting the device in any position, typically within a protective enclosure due to IP00 rating. Wiring must strictly follow the polarity and voltage specifications, and the connection diagram is printed on the housing. The base is not included and must be purchased separately.

Common failure modes for controllers of this kind include failure to ignite, lockout due to flame loss, or no response to reset. Symptoms may include the burner not starting, repeated lockouts, or the LED indicating fault codes. Check the flame sensor for contamination or incorrect positioning, verify the supply voltage is correct, and ensure the safety contacts are functioning properly.
