see section
6.4.2 Versions with current input.
2. Switch on the mains.
3. Apply 4 mA to "4-20 mA input".
4. The servomotor moves to the 0 % position.
5. Disconnect the mains and remove the mains cable.
For all servomotors:
1. Connect the pump to the electrical mains.
2. Switch on the mains.
3. Turn the pump's stroke adjustment button to the 0 % position.
4. Switch off the mains.
