Why is there high air consumption in my HORA PA-N 160 Controller?
High air consumption in the HORA Controller can be caused by several factors. The diaphragm might not be compressed correctly; in this case, tighten the hexagonal nuts until the diaphragm is compressed. Worn seal components can also lead to this issue, so replace the seal components. Finally, check the pipes for leaks and either replace or seal them as necessary.
What to do if the actuator spindle is not moving on my HORA Controller?
If the actuator spindle on your HORA Controller isn't moving, several issues could be the cause. First, ensure the manual control is in the zero position. Next, verify that compressed air is connected to the actuator. If these aren't the problem, the diaphragm may be torn, requiring replacement. The valve cone could also be seized; refer to the Valve Troubleshooting List for guidance. Lastly, the actuator power may be too weak for the valve, requiring a design check and consultation with the valve manufacturer.
How to fix jerky movement of the actuator spindle on my HORA PA-N 160?
Jerky movement of the actuator spindle in your HORA Controller can stem from a few potential issues. Insufficient compressed air could be the culprit, so inspect the compressed air system for damage and ensure sufficient throughput. An incorrectly set position control system might also be the cause; correct the settings. Additionally, a slightly seized valve cone due to dirt particles could be the reason, so consult the Valve Troubleshooting List.
