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.
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/LED1 is illuminated in end position CLOSED
- the green indication light/LED5 is illuminated in end position OPEN
- the indication lights go out after travelling into opposite direction.
The limit switching is set incorrectly if:
- the actuator comes to a standstill before reaching the end position
- one of the red indication lights/LEDs is illuminated (torque fault)
- the status indication S0007 in the display signals a fault.
3. If the end position setting is incorrect: Reset limit switching.
For actuators with position feedback (RWG, potentiometer), a reference operation
has to be performed once the limit switching setting was changed to ensure that the
position feedback (0/4
Operate actuator electrically (via the push buttons OPEN and CLOSE of the
local controls) once to end position OPEN and once to end position CLOSED.
If no reference operation is performed after changing the limit switching, the feedback
signal via the bus is not correct. The bus signals the missing reference operation as
a warning.
If options (e.g. potentiometer, position transmitter) are available: Only close switch
compartment once all optional equipment has been successfully set.
Corrosion due to damage to paint finish
Touch up damage to paint finish after work on the device.
1. Clean sealing faces of housing and cover.
2. Check whether O-ring [3] is in good condition, replace if damaged.
