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

tons
[S1] + [S2] → press simultaneously for 5 s: Activate setting mode
→ press in setting mode for 3 s: Set 4 mA
→ press in setting mode for 6 s: Set 0 mA (only possible for 3-/4-wire version)
[S1]
→ press in operation for 3 s: Switch on/off LED end position signaling
→ touch in end position: Reduce current value by 0.02 mA
→ press in setting mode for 3 s: Set 20 mA
[S2] → press in operation for 3 s: Switch on/off LED end position signaling
→ touch in end position: Increase current value by 0.02 mA
For measuring range setting, voltage must be applied at the 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 required).
