Brahma Microprocessor-based controller BT2310 18049400

The Brahma BT2310 (article 18049400) is a microprocessor-based controller for automatic ignition control, flame monitoring, and safe operation of forced-draught gas, oil, and combination burners in intermittent mode. It operates on 12 V DC supply voltage and is suitable for single-stage or two-stage burners. The device 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 includes a built-in ignition transformer, two independent safety contacts, and supports ionisation, UV, or photodiode flame detectors. The controller has a non-volatile lockout with manual reset, remote reset capability, and a multicolour LED indicator. It weighs 0.27 kg and measures 90 x 85 x 65 mm, with an IP00 protection class (IP40 with base).

Parts of this type are selected by matching the supply voltage, timing parameters (pre-purge and safety times), and flame detector type to the burner's requirements. The controller can be mounted in any position, but due to its IP00 rating, it should be installed in a protective enclosure or cabinet. Wiring must strictly observe polarity and the correct DC voltage level, as incorrect connection can damage the unit. The connection diagram is printed on the housing, and the base is not included and must be purchased separately.

Items of this kind may fail by going into lockout due to abnormal conditions such as no flame, open ionisation circuit, or ignition failure. Symptoms include the burner not starting or shutting down unexpectedly, with the LED indicator showing fault codes. Common checks include verifying the flame sensor position and cleanliness, inspecting wiring integrity and contacts, and ensuring the supply voltage is correct. If a lockout occurs, the cause must be eliminated and the reset button pressed manually or remotely.
