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: (not self-adjust-
ing)
➥
The direction of rotation is correct if the actuator operation in direction
CLOSE and the symbols ( / ) turn counterclockwise:
Figure 87: Direction of rotation / (for “clockwise closing version”)
10.7.2. Direction of rotation at hollow shaft/stem: check
Figure 88: Direction of rotation of the hollow shaft/stem for operation in direction
CLOSE (“clockwise closing” version)
[1] Threaded plug
[2] Seal
[3] Hollow shaft
[4] Protective cap for stem protection tube
[5] Stem
[6] Stem protection tube
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.
Check direction of rota-
tion
1. Move actuator manually to intermediate position or to sufficient distance from
end position.
2. Depending on the version: Unscrew threaded plug [1] with seal [2], protective
cap [4] or stem protection tube [6].
