Start the Piab control via a pneumatic ON/Off valve
The vacuum pump starts and at the same time the bottom flap/door closes, the back pulse container (located inside the top part of the Conveyor) charges with compressed air (line pressure). The suction time begins (adjustable to 1-30 seconds via the pneumatic timer).
When the suction time times out, the control goes into a discharge cycle (adjustable to 1-30 seconds), the vacuum pump will stop, the bottom flap/door opens and the back pulse will clean the filter. And after that it will re-start until the unit is shut off
