10.3.2 Set end position OPEN (white section)
How to proceed 1. Engage manual operation.
10.4 Test run
10.4.1 Check direction of rotation at mechanical position indicator
NOTICE
How to proceed 1. Move actuator manually to intermediate position or to sufficient distance from end

4. Press down and turn setting spindle [1] with screwdriver in direction of the arrow
and observe the pointer [2]: While a ratchet click is felt and heard, the pointer [2]
moves 90° every time.
5. As soon as the pointer [2] is 90° from mark [3]: Continue turning slowly.
6. As soon as the pointer [2] moves to mark [3]: Stop turning and release setting
spindle.
ð The end position CLOSED setting is complete.
7. If you override the tripping point inadvertently (ratchet click is heard after the
pointer has snapped): Continue turning the setting spindle in the same direction
and repeat setting process.
2. Turn handwheel counterclockwise until valve is open.
3. Turn handwheel by approximately half a turn (overrun) in the opposite direction.
4. Press down and turn setting spindle [4] with screwdriver in direction of the arrow
and observe the pointer [5]: While a ratchet click is felt and heard, the pointer [5]
moves 90° every time.
5. As soon as the pointer [5] is 90° from mark [6]: Continue turning slowly.
6. As soon as the pointer [5] moves to mark [6]: Stop turning and release setting
spindle.
ð The end position OPEN setting is complete.
7. If you override the tripping point inadvertently (ratchet click is heard after the
pointer has snapped): Continue turning the setting spindle in the same direction
and repeat setting process.
Perform test run only once all settings previously described have been performed.
The direction of rotation can be checked at the position indicator if available. (Chapter
Check direction of rotation at mechanical position indicator
The direction of rotation must be checked at the hollow shaft/stem if no mechanical
position indicator is available. (Chapter

Valve damage due to incorrect direction of rotation!
à If the direction of rotation is incorrect, switch off immediately.
à Correct phase sequence.
à Repeat test run.
Switch off before reaching the end position.

2. Switch on actuator in direction CLOSE and observe the direction of rotation on the
mechanical position indication:

For mechanical position indication via indicator mark:
The direction of rotation is correct if the actuator operates in direction CLOSE
and the symbols ( / ) turn counterclockwise:
