1. Supply compressed air and open the process valve. The pistons move to the
outer end position. This fixes the threaded rods, if necessary – dependent on the
current setting. Loosening of the lock nuts will then not accidentally change the
current setting.
2. Screw down the lock nuts with sealing ring on both sides. If the threaded rods
have loosened, retighten them by hand until a light resistance is felt.
3. Vent the DAPS and close the process valve. The pistons move to the inner end
position.
4. Adjust the end position:
Observe that a complete turn of the threaded rod can change the swivel angle
approx. 1.5° to 3.5° – dependent on the product design.
– Turning threaded rods clockwise reduces the swivel angle.
– Turning threaded rods anti-clockwise increases the swivel angle.
• Turn both threaded rods equally far so they stop the pistons in operation
simultaneously.
5. Supply compressed air and open the process valve. The pistons run against the
threaded rods into the outer end position.
6. Check the position of the process valve. To change the swivel angle, repeat
steps 3 to 6
7. If the desired position is found, check whether both threaded rods offer resist-
ance to the pistons in the opened process valve position. If necessary, screw in
loose threaded rods carefully until resistance is felt.
8. Screw the lock nuts back onto the threaded rods – tightening torque 5 Nm.
9. Check the mode of operation of the quarter turn actuator (
section 8.4)
8.4 Check the mode of operation of the quarter turn actuator
• Check in cyclical tests, through alternating pressurisation and, if necessary,
venting, whether the quarter turn actuator takes the required positions.
• If necessary, adjust the end positions to the extent the quarter turn actuator
offers this possibility ( section 8.1).
9 Maintenance and care
If used as intended in the operating instructions, the device will be maintenance-
free.
10 Disassembly
Warning
Danger of injury due to uncontrolled movements.
• Switch the tubing system pressureless before dismantling.
1. If necessary, remove any existing limit switches.
2. Remove the pneumatic switching valve.
3. Loosen the screws on the flange of the process valve.
4. Remove the quarter turn actuator (if necessary including mounting adapter and
coupling extension) from the process valve.
11 Troubleshooting
