Brahma 20658621 CE191.4 control box

Brahma CE 191.4 burner control unit (art. 20658621 / 246.124.033) is a highly reliable “burner control unit” from the CE series, designed for automation and safe control of atmospheric gas burners. This device fully manages the combustion process – from ignition to emergency shutdown – and is an ideal solution for heating boilers, air heaters and other gas equipment. Purpose and applications Brahma CE191.4 is designed for modulating (progressive) gas burners with a single flame, operating in intermittent (cyclic) mode. The device: Is compatible with both fanless burners and forced‑air burners. Is widely used in combination and heating boilers, air heaters, infrared (IR) heaters and water heaters. Key feature: electric reset (volatile lockout) The main distinguishing feature of this model is its reset mode: Electric reset: In the event of a safety lockout (flame absence or flame failure), restarting the burner does not require manually pressing a Reset button on the housing. Simply disconnect and then reapply power to the unit (interrupt the power supply for a few seconds). This is very convenient for systems with remote control. Main timing parameters (TW/TS) For article 20658621, the following factory parameters are set – they are extremely important to consider when replacing the unit: Parameter Value Pre‑purge time (TW / tp / t1) 30 seconds Safety time (TS / t2) 10 seconds Supply voltage 230 V, 50‑60 Hz Power consumption 7 VA Important: Before purchasing, be sure to check the timing parameters of your burner. Choosing the wrong unit (for example, with a pre‑purge time of 1.5 s instead of 30 s) can lead to improper operation or operational failures. Other key features Ionisation flame monitoring – Provides an immediate reaction to flame loss – less than 1 second. Built‑in ignition transformer – Simplifies burner installation by eliminating the need for a separate ignition unit. Volatile lockout – In the event of a fault or power interruption, protection is maintained. Restart is only possible as described above. Protection against external influences – The housing protects the electronics from dust and moisture (IP40 protection class), mechanical damage, and includes built‑in protection against voltage surges and short circuits. Long service life – Rated for at least 250,000 switching cycles. Wide temperature range – Operates reliably at temperatures from –20 °C to +60 °C.

They are not interchangeable without checking and re‑adjusting the burner. When replacing, always compare the timing parameters (TW/TS) on the label of your old unit with those of the new one. Installation and operation Mounting – The device is intended for installation in dry, ventilated places inside a control cabinet. A connection base is purchased separately; the wiring diagram is printed on the housing. Maintenance – It is recommended to periodically check the reliability of contacts and the cleanliness of the ionisation electrode. Lockout reset – In the event of a safety shutdown (red LED lit), find and eliminate the cause (check gas supply and draught), then disconnect and reapply power to the unit.
