Skrzynka sterująca Brahma 37173614 CE31FR

Brahma CE31FR (art. 37173614) is a modern device, often referred to as a “burner control unit” or “burner management unit”. It is specifically designed for complete automation and safety of progressive (modulating) gas burners with a fan. The main task of the CE31FR is to fully manage the combustion process. This includes control of the pre‑purge of the chamber, generation of a spark for ignition, continuous monitoring of flame presence and safe burner shutdown in any abnormal situation. This model is widely used in: Heating and combination boilers of various capacities. Hot air generators and hot air guns (Master, OKLIMA, etc.). Radiant tube heaters and water heaters. Combi steamers and other process equipment. Thanks to its support for “progressive” burners, the controller provides smooth power modulation, allowing the system to operate efficiently over a wide range of thermal loads. Main functions and features Here are the key features of this “burner management unit”: Electric reset (volatile lockout): The main feature of this version. After any safety shutdown (e.g., due to flame loss), the controller latches into a locked state. To restart it, simply disconnect power for a few seconds and then restore it. This distinguishes it from versions with a manual reset button. Fully automatic cycle: The microprocessor device fully manages the entire burner start‑up sequence, from purging to flame monitoring and safety shutdown. Reliable flame control: Uses the ionisation method, based on the physical property of a flame to rectify alternating current. Response time on flame loss is less than 1 second, guaranteeing instantaneous gas shut‑off. High ignition power: Equipped with a built‑in high‑voltage transformer with solid‑state ignition. The spark voltage is 20 kV, ensuring reliable ignition even under difficult conditions. Noise immunity and durability: A built‑in EMC filter suppresses electromagnetic interference from the ignition transformer, and there is also protection against voltage surges and overloads (fuse). Long service life and safety standards: The controller is rated for at least 250,000 cycles, and its design complies with stringent European standards EN298:2003 and CE PIN 0694BR1154. Technical specifications Parameter Value Model Brahma CE31FR (art. 37173614 / 246.124.237) Supply voltage 230 V, 50/60 Hz (110‑120 V version available) Power consumption 2.5 VA Pre‑purge time (tv/tp) 1.5 seconds Safety time (ts) 10 seconds Waiting time (tw) 1.5 seconds Minimum ionisation current 1.2 µA (0.5 µA on request) Burner type Atmospheric, progressive (modulating), with fan Operating mode Intermittent (must be stopped once every 24 hours for self‑diagnosis) Lockout reset Electric (by disconnecting and restoring power) Enclosure protection class IP00 (requires installation in a dust‑ and moisture‑protected location) Dimensions (W×H×D) 107 × 81 × 36 mm Weight 0.17 kg Important: For correct operation of your equipment it is critical that the timing parameters of the unit (tv/tp = 1.5 s, ts = 10 s, tw = 1.5 s) match your burner’s factory settings. Interchanging controllers from different series without verifying these parameters is not permitted. Compatibility and replacement Compatible burners: The device is compatible with a wide range of progressive atmospheric gas burners, including those from leading brands: Riello, Weishaupt, Giersch, Viessmann, Lamborghini and others. Accessories: The connection base is not included and must be purchased separately. Molex connectors are used for connection. Installation and operation Mounting: The device can be mounted in any position, but always in a dry, ventilated place inside a control cabinet. This is necessary because of the low IP00 protection class. Wiring: Before starting work, ensure power is disconnected. Power supply must be provided through a fast‑acting external fuse, as recommended by the manufacturer. The connection diagram is printed on the housing. Initial start‑up and maintenance: Ensure there is no false flame before start‑up. For stable operation it is recommended that the ionisation current be 3–5 times higher than the minimum value (1.2 µA). Periodically check the cleanliness of the ionisation electrode and the reliability of connections. Lockout reset: In the event of a safety lockout (red LED lit), find and eliminate the cause (check gas supply, electrode), then either press the reset button or disconnect and restore power to the unit. Advantages over alternatives High reliability and service life: More than 250,000 operating cycles guarantee a long service life. Convenience of electric reset: This feature makes it very convenient for systems with remote control where manual access to the unit for resetting may be difficult. Powerful built‑in ignition (20 kV): Simplifies installation and reduces external components, ensuring reliable ignition. High level of protection: Compliance with strict European safety standards EN298 and built‑in protection against interference and voltage surges guarantee stable operation. Versatility of application: Ideally suited for a wide range of gas heating equipment, from domestic boilers to industrial plants.
