Boîtier de commande Brahma 30721325 CE31

Brahma CE31 is a specialised controller for atmospheric gas burners with a fan, operating in intermittent (cyclic) mode. It is suitable for single‑stage and two‑stage systems, providing precise control of the combustion process. The control unit is indispensable in various heat‑generating equipment: Heating and combination boilers Hot air generators and hot air guns Combi steamers and industrial furnaces Infrared (IR) heaters and water heaters Key feature: electric reset (volatile lockout) The main distinguishing feature of this model is the electric lockout reset. This means that, unlike units with a manual reset, restarting the burner after a fault does not require manually pressing a Reset button on the housing. Instead, after eliminating the cause of the fault, simply disconnect power from the unit for a few seconds and then restore it. This feature – known as a volatile lockout – is extremely convenient for systems with remote control where access to the unit may be difficult. Main timing parameters (TW/TS) For correct operation it is critically important that the controller parameters match your burner settings. For article 30721325 these are: Parameter Value Pre‑purge time (tv/tp) Not specified, but this model is often supplied with 10 seconds Safety time (ts) 10 seconds Waiting time (tw) 30 seconds Other key features Ionisation flame control – The controller uses an ionisation electrode for flame monitoring. Response time on flame loss is less than 1 second, ensuring instantaneous gas shut‑off in an emergency. Automatic self‑diagnosis – Each time the device is switched on, it performs a self‑check of all key components (signal amplifier, pressure switch relay, etc.), guaranteeing its readiness for safe operation. Reliability and service life – The controller is rated for more than 250,000 switching cycles under maximum load, confirming its high reliability. Protection against external influences – A built‑in varistor and short‑circuit protection protect the device against voltage surges and short circuits. The robust housing protects against mechanical damage.

It is fully compatible with a wide range of burners from well‑known brands (Riello, Baltur, Weishaupt, Lamborghini). The connection base is not included and must be purchased separately. The connection diagram is printed on the device housing. Pay attention to the timing parameters when replacing! Installation and operation Mounting – The device must be installed in a dry, ventilated place inside a control cabinet to achieve dust and moisture protection (IP40). Wiring – Always disconnect power before connecting. Power to the unit should be supplied via a disconnection device and include an external fast‑acting fuse rated at no more than 2 A, as recommended by the manufacturer. Maintenance – Periodically check the reliability of contacts and the cleanliness of the ionisation electrode. For stable operation it is recommended that the ionisation current be 3–5 times higher than the minimum value. Lockout reset – In the event of a safety shutdown, identify and eliminate the cause (e.g., gas supply interruptions or pressure switch tripping), then disconnect power to the unit for a few seconds and restore it.
