Note
Leakage
Besides continuous air consumption, a leakage can cause the positioner to try to compensate
the position deviation. This will result in premature wear in the entire control device.
• Check if there is leakage with "LEAKAGE TEST".
• If there is leakage, check the pneumatic connections for leaks.
