2. Operate actuator using push buttons OPEN - STOP - CLOSE.
The limit switches are set correctly if (default indication):
- the green indication light is illuminated in end position CLOSED
- the red indication light is illuminated in end position OPEN
- the indication lights go out after travelling into the opposite direction.
The limit switches is set incorrectly if:
- the actuator comes to a standstill before reaching the end position
- the yellow indication light is illuminated (torque fault).
3. If the end position setting is incorrect: Reset limit switches.
4. If the end position setting is correct and no options (e.g. potentiometer, position
transmitter) are available: Close switch compartment.
Option
EWG 01.1 electronic position transmitter signals the remote position or the valve
position. On the basis of the actual valve position sensed by hall sensor, a current
signal between 0 20 mA or 4

The EWG is housed in the actuator switch compartment. The switch compartment
must be opened to perform any settings. Refer to <Switch compartment: open>.
All settings are made via the two push buttons [S1] and [S2].
