Brahma Control box 20080005

The Brahma Control box 20080005 is a microprocessor-based controller for atmospheric gas burners in heating and heat generation systems. It operates with a supply voltage of 230 V and features a safety time of 10 seconds and a pre-purge time of 1.5 seconds. Flame detection is via ionisation, with a flame loss reaction time of less than 1 second. The device supports progressive (modulating) burner stages and is certified to EN 298:2003. It is designed for intermittent operation and has a service life of 250,000 cycles under maximum load.

Control boxes of this type are selected by matching the supply voltage, safety time, pre-purge time, and flame detection method to the burner's requirements. They are typically mounted on a DIN rail or by screws, and installation position is flexible. Ensure the control box is compatible with the burner's fuel type and stage control (e.g., progressive). The flame detector type (ionisation) must correspond to the burner's electrode configuration.

Common failures include lockout due to flame loss, which triggers a manual reset. Symptoms may include the burner failing to start or shutting down unexpectedly. Check the ionisation electrode for contamination or wear, and verify wiring integrity and gas supply. A red LED indicates a safety lockout, requiring manual reset after resolving the fault.
