DIP 1 DIP 2
ON
Position of DIP 2 effec-
tive
Actuator turns to the
OPEN position
OFF
Actuator remains in the
current position (DIP 2
not effective)
Actuator turns to the
CLOSED position
(refer to explanation on the left)
6. Setting Up the Actuator
Attention
Check the following before connecting the actuator to the
mains:
• Does the main voltage correspond to the spe-
cications given on the type plate
• 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, the end positions should be checked and
adjusted if necessary.

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.
