صندوق التحكم في نظام «Brahma» 18049400 BT2310

Brahma BT2310 (art. 18049400) is a microprocessor-based controller (“burner management unit”) from the EUROBOX series, designed for automatic ignition control, flame monitoring and safe operation of forced‑draught gas, oil and combination burners in intermittent (cyclic) mode. The device is suitable for both single‑stage and two‑stage forced‑air burners. Applications include: Gas, oil and combination boilers (domestic and industrial) Hot air guns, warm air generators Air heaters, process furnaces Burners from Riello, Baltur, Weishaupt, Lamborghini and other brands Key feature: 12 V DC power supply This version of the BT2310 (art. 18049400) operates on 12 V direct current. This fundamental difference from standard 230 V AC units makes it an ideal choice for systems with low‑voltage control circuits, stand‑alone installations, and for directly replacing obsolete low‑voltage controllers. Connection to 220 V mains is strictly prohibited and will damage the unit. Main functions and features Fully automatic combustion cycle – The unit manages the sequence: false flame check → pre‑purge (10 seconds) → ignition → flame monitoring → safe shutdown on flame loss. Ionisation flame control (supports UV sensor and photodiode) – Flame detection via an ionisation electrode, UV photodetector or photodiode. Response time on flame loss is less than 1 second, meeting strict safety standards. Non‑volatile lockout with manual reset – Under any abnormal condition (no flame, open ionisation circuit, ignition failure) the unit goes into a safe state. Restart is only possible manually by pressing the Reset button on the housing after the cause has been eliminated. This prevents the burner from starting unintentionally while a fault persists. Two independent safety contacts – A key safety feature. The controller is equipped with two independent safety contacts for controlling the fuel solenoid valves, providing redundancy for critical circuits. Built‑in high‑voltage ignition transformer – No external ignition unit required. Automatic self‑check at each start‑up – Diagnostics of key circuits. Lockout alarm output – Allows connection of external signalling (lamp, buzzer). Remote control – Possibility to connect external signals for remote lockout and reset, convenient when the burner is located in a hard‑to‑reach place. Informative LED indication – A multicolour LED on the front panel shows the current operating status and provides fault codes for quick diagnostics. High reliability – Controller service life: more than 250,000 switching cycles. Standards compliance – The device is certified according to European directives and meets standards EN298:2003 (automatic burner control systems for gas burners), EN676:2003 (forced‑draught gas burners), DIN 4788 and EN230:2005 (oil burners).

Before purchasing, always check the tv/tp and ts values printed on the unit’s housing and ensure they match your burner’s factory settings. For article 18049400 typical values are tv/tp = 10 s, ts = 10 s. Do not confuse with article 18049401 (24 V DC, tv/tp = 10 s, ts = 10 s) or 18049430 (24 V DC, adjustable parameters). Compatibility and replacement Compatible burners and equipment – The unit is suitable for a wide range of forced‑draught gas, oil and combination burners, including equipment from Riello, Baltur, Weishaupt, Lamborghini. Direct replacement – Article numbers 18049400 and 246.124.152 are identical. The BT2310 series also includes articles 18049401 (24 V DC, 10/10 s) and 18049430 (24 V DC, programmable). Caution: Interchangeability only when supply voltage and timing parameters match. Accessories – A connection base is not included and must be purchased separately. The connection diagram is printed on the device housing. Installation and operation Mounting – The device can be mounted in any position. The housing has standard dimensions, making it easy to replace obsolete controllers. Due to IP00 protection class, it is recommended to install the unit in a protective enclosure/cabinet that prevents dust and moisture ingress. Wiring – Strictly observe polarity and the 12 V DC voltage level. Incorrect connection to 220 V or 24 V DC will damage the unit. Disconnect power before starting work. Initial start‑up – Before start‑up, ensure the combustion chamber has been purged, the ionisation electrode (or UV sensor) is correctly positioned and provides a stable flame signal. Lockout reset – When a safety lockout occurs, find and eliminate the cause, then press the Reset button on the housing. Remote reset is also supported when an appropriate external button is connected. Maintenance – Periodically check the condition of the contacts, wiring integrity, and the cleanliness and position of the flame sensor. Operating mode – The unit is designed for intermittent operation. To maximise service life and safety, the system must be forced to stop at least once every 24 hours. Advantages over alternatives Low‑voltage power supply (12 V DC) – Ideal solution for systems with low‑voltage control circuits, stand‑alone installations and replacing obsolete controllers. Versatility – Suitable for gas, oil and combination burners, both single‑stage and two‑stage. Reliability – Service life of more than 250,000 cycles, proven by the manufacturer. Safety – Manual lockout reset + non‑volatile fault memory + double safety contacts meet the highest EN298 standards. Remote control – Support for external lockout and reset signals for operational convenience. Italian quality – High‑grade components, strict production control.
