Why is my STI SC actuator too slow?
If the STI Controller actuator is too slow, first, check if the supply pressure is low and adjust it accordingly. Also, verify the speed control settings and adjust them to increase the flow. If the issue persists, the main valve may be worn, and you should consult the valve manufacturer's documentation.
How to troubleshoot an STI Controller actuator that doesn’t work properly?
If the STI Controller actuator isn't working properly, start by checking the hydraulic supply line for any issues. If the supply is fine, the main valve might be defective, and you should consult the valve manufacturer's documentation. If problems continue, this could indicate a failure of the control group, and you should contact STI s.r.l. - Customer Care Dept.
What to do if there are leakages on hydraulic circuits in STI SC Controller?
If you notice leakages on the hydraulic circuits of your STI Controller, it could be due to deterioration or damage to the gaskets, or loosened fittings. Try tightening any loose fittings. If the leakages persist, or are due to damage to the fittings, contact STI s.r.l. - Customer Care Dept.
Why is my STI SC Controller actuator too fast?
If the STI Controller actuator is too fast, try resetting the system, as high supply pressure could be the cause. Also, check the speed control settings and adjust them to decrease the flow.
How to correct an incorrect valve position on an STI SC Controller?
If the valve position on your STI Controller is incorrect, it might be due to a wrong adjustment of the mechanical stops or wrong electric limit switches indication. Try re-adjusting the settings.
What causes leakages on the hydraulic cylinder of an STI Controller?
If there are leakages on the hydraulic cylinder of your STI Controller, it is likely due to damage to the seals. Replace the cylinder seals to resolve this issue.
