Depending on the technical requirements for the process, cool-
ing can be implemented in two stages. Actuating the air valve
for the burner (terminal 22) initiates “normal” cooling; actuating
a second air valve for the additional cooling air connection
initiates additional cooling. The additional cooling air valve is
actuated separately by the process control system. For wiring
on site, we recommend using a BCU..C with a supplementary
terminal strip (e.g. terminals 32/33 for additional air valve).
