2. Check the functioning and operation of each individual
valve/actuator combination by actuating the manual over
ride as shown in the following diagrams.
Note
Incorrect actuation of the non−detenting manual override
can lead to malfunctioning or damage to the manual over
ride.
·
Use a screwdriver (blade width max.3mm) to actuate
the manual override.
·
Operate the manual override to max. 25 N.
3. With a detenting manual override: After testing the valves,
make sure that all manual overrides are in their initial
positions again.
Caution
Valves with manual overrides in switch position can move
actuators unintentionally during commissioning. This can
cause injury to people and damage to property.
·
Prior to commissioning, reset all manual overrides to
their initial positions again.
If the manual override is in the actuated state, it is not
possible to reset the valve to its neutral position with an
electric signal. The manual override is dominant in this
case.
4. Switch off the compressed air supply after testing the
valves.
