Then abide to the maintenance plan.
Switch on the compressed air to supply the VAC and the vibrator.
Position the VAC at the desired location and activate the 2/2-way ball
valve on the VAC to generate the vacuum required under the suction
cup.
Check the VAC for tightness. If the VAC can be loosened by hand,
• check the mounting surface for unevenness and contamination,
• control and, if necessary, increase the pressure (e.g. with a
maintenance unit with pressure regulator).
Start the vibrator with the 3/2-way manual slide valve on the hose set.
Set the frequency of the vibrator by means of a throttle check valve
(e.g. on the hose set HG ... with DRV) so that sliding of the VAC is
prevented.
