7. Setting Up the Actuator
Attention
Check the following before connecting the actuator
to the mains:
ł Does the mains voltage correspond to the speci-
fications given on the typeplate
ł Has the actuator been connected correctly
(see Section 5.1)
Adjustments
If a complete valve is supplied by Georg Fischer,
no further adjustments are required.
After installation by the customer or after repair
work, the end positions should be checked and if
necessary adjusted.
Limit switch allocation
Switch S1 (bottom) opens at «open» position
Switch S2 (top) opens at «closed» position
Procedure
Set both switching cams (1) to S1* and S2* so that
the rotating angle is less than 90°.
Let the actuator turn until a limit switch is activated.
By adjusting the respective switching cam, the end
position can be set since the actuator follows the
cam.
* S1: «open», bottom
S2: «closed», top
