2.6.4 Manual override
When the pressure supply is switched on, the manual override can be used to switch a valve to an elec
trically unactuated, de-energised state. The manual override should primarily be used when commis
sioning the pneumatic system in order to check the functional and operational performance of the valve
or of the valve-actuator combination.
