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
tube [4].
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.
Figure 36: Hollow shaft/stem movement (for “clockwise closing”)
[1] Threaded plug
[2] Seal
[3] Hollow shaft
[4] Protective cap for stem protection tube
[5] Stem
[6] Stem protection tube
4. Correctly fit/screw on threaded plug [1] and seal [2] or protective cap for stem
protection tube [4], fasten thread.
9.6.3. Limit switching: check
1. Set selector switch to position Local control (LOCAL).
2. Operate actuator using push buttons OPEN, STOP, CLOSE.
➥
The limit switching is set correctly if (default indication):
- the yellow indication light is illuminated in end position CLOSED
- the green indication light is illuminated in end position OPEN
- the indication lights go out after travelling into the opposite direction.
➥
The limit switching is set incorrectly if:
- the actuator comes to a standstill before reaching the end position
- the red indication light is illuminated (torque fault).
3. If the end position setting is incorrect: Reset limit switching.
4. If the end position setting is correct and no options (e.g. potentiometer, position
transmitter) are available: Close switch compartment.
