The 500 Ω resistor converts the
4...20 mA current signal to a voltage
signal DC 2...10 V

Procedure
1. Apply 24 V to connection 1 and 2
2. Disconnect connection 3:
- with upwards direction of motion:
closing point at top
- with downwards direction of
motion: closing point at bottom
3. Short circuit connections 2 and 3:
- Actuator runs in the opposite
direction
