17.2 Control panel
The sequencer is designed to control the air pulse cleaning valves (jet pulse). It allows the
programming of a cleaning sequence which will be repeated permanently acting on the solenoid
valves. The pilot indicating lights (diodes) show which solenoid is powered. For units equipped with
auxiliary accessories (rotary valves, screw conveyors), refer to the documents included with the
control panel.
