Brahma 20653005 CE11 control box
Brahma CE11 (art. 20653005 / 246.124.208) is a modern microprocessor‑based “burner control unit” from the Euroflat series, designed for comprehensive automation and safety of atmospheric modulating gas burners without a fan, operating in intermittent mode. Purpose and applications Brahma CE11 fully automates the burner control process, performing all key operations: from pre‑purge of the combustion chamber and ignition to continuous flame monitoring and safety shutdown. This makes it an indispensable component for ensuring stable and safe operation of heat‑generating equipment, for example: Combination and heating boilers Air and infrared heaters Water heating devices The device fully complies with the European safety standard EN 298, confirming its high quality and reliability. Main features Microprocessor control – Ensures high accuracy of timing sequences and operational stability. Electric lockout reset – After a safety shutdown, model 20653005 restarts by briefly interrupting and restoring power, eliminating the need to physically approach the unit to press a reset button. Built‑in ignition transformer with EMC filter – Simplifies installation and ensures stable, interference‑free operation of the ignition system. Reliable flame monitoring – Uses an ionisation electrode for flame detection. Response time on flame loss is less than 1 second, guaranteeing instantaneous gas shut‑off. Robust impact‑resistant housing – Made of flame‑retardant plastic, protecting internal electronics from mechanical damage. Comprehensive electronic protection: Varistor – Protection against short‑term voltage surges. Built‑in fuse – Protection against short circuits on outputs. Undervoltage and overvoltage protection – The device enters a safe mode when supply voltage deviates critically. Technical specifications Parameter Value Model Brahma CE11 Article numbers 20653005, 246.124.208 Supply voltage 230 V AC, 50/60 Hz Burner type Atmospheric, progressive (modulating), without fan Operating mode Intermittent (must be stopped once every 24 hours) 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 Enclosure protection IP00 (IP20 or higher achieved by installation in a protective enclosure/cabinet) Operating temperature –20 °C to +60 °C Weight 0.2 kg Dimensions (W×H×D) 116 × 96 × 36 mm Compatibility and replacement Compatible equipment – The unit is designed for atmospheric modulating gas burners without a fan. Direct replacement – Article numbers 20653005 and 246.124.208 are identical. 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. Due to IP00 protection class, it is recommended to install the unit in a protective enclosure/cabinet to prevent dust and moisture ingress. Wiring – Strictly observe correct connection of live and neutral wires. Disconnect power before starting work. Initial start‑up – Before start‑up, ensure the combustion chamber has been purged and the ionisation electrode is correctly positioned. Maintenance – Periodically check the condition of contacts, wiring integrity, the built‑in fuse, and the cleanliness and position of the ionisation electrode. Operating mode – The unit is designed for intermittent operation. To maximise service life and safety, the manufacturer recommends forcing a system stop at least once every 24 hours. Advantages over alternatives Electric reset – Convenience of remote restart after a fault without physical access to the unit. Easy integration – Compact dimensions and mounting in any position allow easy integration into existing systems. High reliability – Microprocessor control and multi‑level protection against external influences ensure a long service life and stable operation. Italian quality – High‑grade components and strict production control. Package contents Brahma CE11 burner control unit (art. 20653005) – 1 pc. Quick installation and operation guide.
