Manual override
The manual override (see Fig. 4/7) is used prin-
cipally when the pneumatic system is commis-
sioned, as a means of checking the function and
effect of the valve or of the valve-cylinder combi-
nation. By operating the manual override, the
user can switch the valve without an electric sig-
nal. Only the compresssed air supply needs to
be switched on.
