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

11.3.1 Set measuring range

For setting, voltage must be applied at the electronic position transmitter.
For output current verification, connect a test device for 0 – 20 mA to measurement
points (+/–) (for 2-wire systems, connecting a test device is imperatively required).
