Brahma Control box SM592N.2 36223151

The Brahma SM592N.2 control box is a gas burner control unit designed for atmospheric burners in intermittent operation, with or without a fan. It operates on a supply voltage of 220–240 V and uses ionization flame detection. The device features a safety time adjustable from 3 to 60 seconds and a pre-purge time from 1.5 to 40 seconds. It includes two independent safety contacts for gas valve control and is housed in a plastic body with IP 00 protection. The net weight is 0.17 kg.

When selecting a control box of this type, ensure the supply voltage matches the system (e.g., 220–240 V). The safety time and pre-purge time must be compatible with the burner's requirements. The flame detector type (ionization) must correspond to the burner's electrode configuration. The control box should be mounted in a location that does not require higher than IP 00 protection, and the electrical connections must match the wiring diagram of the existing unit.

Common failures of such control boxes include failure to start, lockout after safety time, or intermittent operation. Symptoms may include the burner not igniting, the system going into lockout mode, or the flame signal being lost during operation. Check the ionization electrode, wiring, and supply voltage. If the control box does not reset after a lockout, it may be faulty.
