Checking the va lve functions
Manual override
Warning
Before actuating the manual override:
• Disconnect the power supply for the valve solenoid coils
from the multipin connection.
You will thereby avoid undesired actuation of the valve
solenoid coils.
• Before switching on the power supply, make sure that all
manual override locking actuations are in their basic
positions.
Y o u will thereby avoid undefined switching states of the
valves.
Y ou should use the manual override especially when commis-
sioning the pneumatic system, in order to check the function-
ing and operation of the valve or the valve-cylinder-combina-
tion.
By actuating the manual override, you can switch the valve
without an electric signal. You only need to switch on the
compressed air supply.
