Brahma CE31 (art. 30615506 / 246.124.063) is a modern microprocessor-based “burner control unit” (burner management unit) that serves as a key component for building safe and highly efficient gas heating systems. It is designed for comprehensive control and safety of progressive (modulating) gas burners with a fan, operating in intermittent (cyclic) mode. Purpose and applications This burner management unit fully automates the burner control process – from ignition to safe shutdown – while maintaining stable combustion. The device is ideally suited for a wide range of heat‑generating equipment, including: Heating and combination boilers. Industrial and domestic heat generators. Air heaters, combi steamers, radiant tube heaters and water heaters. Key technical specifications Accurate controller parameters are critical for proper selection and system setup. Parameter Value Model Brahma CE31 Article numbers 30615506, 246.124.063 Supply voltage 230 V AC, 50/60 Hz (110‑120 V version available) Power consumption 9 VA Pre‑purge time (tv/tp / t1) 30 seconds Safety time (ts / t2) 5 seconds Waiting time (tw / t3) 30 seconds Flame control Ionisation electrode (based on flame rectification) Response time on flame loss < 1 second Minimum ionisation current 1.2 µA Lockout reset Electric (power interruption) Enclosure protection class IP00 Operating temperature –20 °C to +60 °C Max. humidity 95% at 40 °C Dimensions 116 × 96 × 36 mm Weight 0.2 kg Safety standards EN298:1993, EN298:2003 Main functions and features In addition to the basic parameters, this model offers several important design and functional advantages. Rated service life and reliability – The controller is rated for more than 250,000 operations, confirming its durability. A built‑in varistor provides reliable protection of the electronics against voltage surges. Electric lockout reset – Unlike many other burner controls, this model has a volatile lockout. This means that after a safety shutdown (e.g., due to flame loss), restarting the burner does not require manually pressing a Reset button on the housing. Simply briefly interrupt and then restore power to the unit. This feature is extremely convenient for systems with remote control. Built‑in safety systems – The controller uses a two‑electrode arrangement, with separate electrodes for ignition and flame detection, increasing system reliability. It is equipped with two independent safety contacts connected in series in the gas valve circuit for redundant safety. Automatic self‑diagnosis – Each time it is switched on, the unit performs a self‑check of its components, including the flame signal amplifier and air proving relay, guaranteeing its readiness for safe operation before ignition even begins. Compatibility and replacement Suitable equipment – The controller is designed for progressive (modulating) atmospheric gas burners with a fan. Caution – Different versions of the CE31 can have different timing parameters. Article numbers 30615506 and 246.124.063 are direct equivalents, but they are not interchangeable with other articles in this series due to different timing parameters. Installation and operation recommendations Mounting – The device should be installed in a dry, ventilated place inside a protective control cabinet, since its IP00 protection class means it has no protection against dust or moisture ingress. Wiring – All connections are made via a separately purchased base. The connection diagram is printed on the device housing. Maintenance – Periodically check the reliability of contacts and the cleanliness of the ionisation electrode for stable operation. Lockout reset – In the event of a safety lockout, first eliminate the cause (e.g., gas supply interruptions), then restart by disconnecting power for a few seconds and reapplying it. Package contents Brahma CE31 burner control unit (30615506) – 1 pc. Quick installation and operation guide. Note: The connection base, ionisation electrode and other accessories are sold separately.
