UC400 with field supplied 0-10VDC actuator:
- Verify 24v hot to ground. This would be the tab side of the 3 pin connector (red or blue or both depending on options). (J17-14 in this example).
- The middle wire would be DC common. (Wired to J5-2).
- The opposite of the tap side (24v hot) will be your 0-10vdc signal. (Wired to J5-1).
