The programming unit follows predetermined sequences ofactions and always operates in conjunction with a flame detector device for each of the burners controlled.According to predetermined sequences it may enable the burner to start up independently, or in combination withother burners, even when one or more burners are already in operation. It supervises their operation independentlyand causes controlled shut-down, safety shut-down and, if appropriate, lock-out of one or all of the burners underits control.3.2.2.9programmethe sequence of control operations determined by the programming unit involving switching on, starting up,supervising and switching off the burner3.2.2.10flame detector devicea device by which the presence of a flame is detected and signalled.It can consist of a flame sensor, an amplifier and a relay for signal transmission.
