5. Without the indicator disc:
→
Unscrew threaded plug [1] and seal [2] or cap for stem protection tube [4]
and observe direction of rotation at hollow shaft [3] or the stem [5].
➥
The direction of rotation is correct, if actuator runs in direction CLOSE and
hollow shaft or stem turn clockwise.

9.9.2 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/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), or the following
fault signals are displayed:
-
Status indication S0: FAULT IND.
-
Status indication S1: TORQUE FAULT (OPEN) or TORQUE FAULT
(CLOSE)
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.
9.9.3 Reference operation position feedback: perform
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 – 20 mA) supplies correct values:
