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. 4 mm) to actuate
•
the manual override.
Actuate the manual override with a max. of 25 N only.

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 activated manual overrides can move actuators
unintentionally during commissioning. This can cause
injury to human beings 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 pos-
sible to reset the valve to its neutral position with an elec-
tric signal. The manual override is dominant in this case.
