7.5 After wiring
What to check after wiring
Once the wiring of the actuator is completed, please check the
following:
1. Make sure that the power supply voltage matches the
information on the sticker located 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 in the closing direction (usually
clockwise) rotation and check that the motor rotates in the
right direction.
5. Using a screwdriver, press the lever on the closed limit switch
and make sure that the motor stops.
6. Repeat steps 4 and 5 for the opening direction (usually
counterclockwise).
7.6 Heating element
Each actuator includes a heating resistor.
As soon as the actuator is installed in the field, it is recommended
to power the resistor to prevent condensation.
Immediately put the cover back in place after start-up while
ensuring its seal is clean. Never leave the actuator electrical
components without their protection cover.
In case of water intrusion:
• Dry electrical components before putting the cover back on.
• Check the electrical insulation.
