Burner Control Brahma G22 S03N – Once the thermostats are closed, the controller energizes the burner motor; in this phase the device proceeds to a self-checking process of the flame detection and safety circuit. At the end of pre-purge time the output of the first oil valve is powered. If flame is detected, at the end of safety time, the controller de-energizes the ignition transformer and goes to running position. At the end of safety time, in the double stage controllers, the ignition transformer is de-energized and, contemporaneously, the output of the second oil valve is energized. If no flame is detected within safety time, at the end of the same the controller proceeds to lockout and so the valve, ignition transformer and motor are de-energized, and the lockout signal is activated. The following cycle diagrams are useful to better un
APPLICATION
