8.3. Test run
8.3.1. Check direction of rotation at hollow shaft/stem
Figure 47: 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!
→
Actuators in version with Combi-Switch: If the direction of rotation is wrong,
switch off immediately (turn selector switch to OFF).
→
Actuators in version with control panel for magnetic pen: If the direction of
rotation is wrong, switch off immediately (tap STOP with magnetic pen).
→
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].
3. Switch on actuator in direction CLOSE and observe direction of rotation at hollow
shaft [3] or stem [5]:
➥
The direction of rotation is correct if the actuator moves in direction CLOSE
and the hollow shaft in clockwise direction, or the stem moves downward.
4. Correctly fit/screw on threaded plug [1] with seal [2], protective cap [4] for stem
protection tube [6], fasten thread.
