Checking the valve 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.
You will thereby avoid undefined switching states of the
valves.
You 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.
Types of manual override
The manual override has been designed to be used in locking
or non-locking form.
Method of actuation Method of operation
Non-locking After actuation the manual over-
ride is reset by a spring.
Locking The manual override remains
actuated until it is reset by hand.
