What to check after wiring
Once actuator wiring is completed, please check the following:
1. Make sure that power supply voltage matches information on
the sticker on the side of the actuator.
2. Check that all connectors or cable glands are correctly
tightened.
3. Manually drive the valve to a mid-travel position.
4. Electrically operate counterclockwise rotation and check
that the motor rotates in the right direction.
