Note
A valve that has been switched by an electric signal cannot be reset by the manual over-
ride. The electric signal is dominant in this case.
• Reset the electric signal before actuating the manual override.
1. Switch on the compre ssed air supply.
2. Check the functioning and operation of each individual valve/actuator combination by actuating the
corresponding manual override as shown in the following diagrams.
Note
Incorrect actuation of the non-detenting manual override can lead to malfunctioning or
damage to the manual override.
• Use a screwdriver ( blade width max. 3 mm) to actuate the manual override.
• Actuate the manual override with a max. of 25 N only.
3. For detenting use of the manual override: After testing the valves, check that all manual overrides
are back in their initial positions.
Caution
Valves with activated manual overrides can move actuators ac c identally during commis-
sioning. This can cause injury to people and material damage.
• Prior to commissioning, reset all manual overrides to their initial positions.
If the manual override is in the actuated state, it is not possible to reset the valve to its
neutral position with an electric signal. The manual override is dominant in this case.
4. Swit ch off the compressed air supply after testing the valves.
