4.2 Manual override
You should use the manual override especially when commis
sioning the pneumatic system, in order to check the function
and operation of the valve or the valve−cylinder−combination.
By actuating the manual override, you can switch the valve
without an electric signal. You only need to switch on the
compressed air supply.
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
override is reset by a spring.
Locking The manual override remains
actuated until it is reset by hand.
