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].

The output current (measuring range 0 20 mA) can be checked at measuring points
[1] and [2].
