1. Turn the upstream one-way flow control valve of the semi-rotary drive and inter-

mediate position completely closed and open it back up one ro tation.

2. Pressurize the system and the product.

3. S tart a test run with low swivel fre quency.

4. Turn all one-way flow control valves open one additional rotation until the de-

sired speed of the end position and intermediate position is reached. This can

bethecaseatdifferenttimes.

6Operation

Note

The intermediate-position module can be destroyed if it runs against an unpres-

surised chamber.

• Make sure that the cha mber from the previous operating status is pressurized

at the semi-rotary drive. Only when the valves are reversed simultaneously is

an air cushion present in the chamber, which makes the function of the ex-

haust air flow control valve possible.
