Manual override (MO)
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-actuator 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.
