Brahma Control box 18058000

The Brahma Control box 18058000 is a microprocessor-based controller designed for forced-draft liquid fuel burners operating in intermittent mode. It supports single-stage and two-stage burners, with or without fuel preheating. The device uses ionisation flame detection and provides non-volatile emergency lockout with manual reset. It features two independent safety contacts on the fuel valve output to prevent fuel leakage. The control box is suitable for boiler equipment, air heaters, process furnaces, and other heat generating equipment.

Parts of this type are selected by matching the series designation, supply voltage, safety and pre-purge times, flame detection method (ionisation, uv, or ir), and the base or plug pattern. The flame detection method must match the existing system; for example, if the original uses ionisation, the replacement must also support ionisation or be compatible with uv/ir as required. The base or plug pattern must align with the existing wiring harness. Confirm these parameters against the existing unit's label before ordering.

When items of this kind fail, the burner may not start or may lock out during operation. Common symptoms include ignition failure, flame loss, or the unit going into a safe state that requires manual reset. Check the flame detector, wiring connections, and the control box's reset button. If the control box is faulty, it may not respond to reset attempts or may repeatedly lock out.
