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 81: Direction of rotation / (for “clockwise closing version”)
9.7.2. Direction of rotation at hollow shaft/stem: 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. Unscrew threaded plug [1] and seal [2] or protective cap for stem protection
