10.5.1.
Direction of rotation at mechanical position indicator: check
Valve damage due to incorrect direction of rotation!
→
If the direction of rotation is wrong, switch off immediately (press STOP).
→
Eliminate cause, i.e. correct phase sequence for cable set wall bracket.
→
Repeat test run.
Information
Switch off before reaching the end position.
1.
Move actuator manually to intermediate position or to sufficient distance from
end position.
2.
Switch on actuator in direction CLOSE and observe the direction of rotation on
the mechanical position indication:
→
For self-adjusting mechanical position indication:
➥
The direction of rotation is correct if the actuator operates in direction
CLOSE and arrow
turns clockwise in direction CLOSE (symbol
).

(for “clockwise closing” version”)
→
For mechanical position indication via indicator mark: (not self-adjust-
ing)
➥
The direction of rotation is correct if the actuator operation in direction
CLOSE and the symbols (
/
) turn counterclockwise:
