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 offline using the diagnostic parameter "11.LEAK" whether leakage is present.
● If there is leakage, check the pneumatic connections for leaks.
