Brahma Burner control unit CE191.4 20658621

The Brahma CE191.4 burner control unit (SKU 20658621) is a control box for gas burners with forced draft, operating in intermittent mode. It manages ignition and flame monitoring via an ionisation electrode, with a safety time of 10 seconds and a pre-purge time of 30 seconds. The unit operates on 230 V supply voltage, has a protection class of IP40, and weighs 0.275 kg. It features an electric reset (volatile lockout) and reacts to flame loss in less than 1 second. The ambient temperature range is -20 to 60 °C, and the service life under maximum load is 250,000 cycles.

When selecting a replacement control box of this type, verify the supply voltage, safety time, and pre-purge time match the burner's requirements. The flame detector type (ionisation) must be compatible with the existing sensor. Ensure the unit's protection class and ambient temperature range suit the installation environment. Mounting may require a separate base, and the wiring diagram is typically printed on the housing. Compare the timing parameters on the old unit's label with the new one before installation.

Typical failures of such control boxes include loss of flame signal, leading to a safety lockout indicated by a red LED. The burner may fail to ignite or shut down unexpectedly. Check the ionisation electrode for cleanliness and proper positioning, and verify the gas supply and air supply are adequate. If the unit locks out, it may require a power cycle to reset, depending on the reset mode.
