What to do if all valves and valve LEDs are not operating on SMC Networks Control Unit?
- RRobert ValdezAug 1, 2025
If all valves and valve LEDs are not operating on your SMC Networks Control Unit, there could be a few reasons. First, check for any loose screws connecting the SI unit and the valve manifold. Second, ensure the solenoid valve common specification matches the output polarity of the SI unit. Finally, the solenoid valve itself may be defective, in which case you should follow the troubleshooting steps for the solenoid valve.
