9.2.2.11 Offline leakage test
Application
Use this menu command to open an online dialog in which you can recognize following
execution whether a leakage is present in the actuator or in the piping.
You will also obtain information about the states in the diagnostic field 'Leakage test status'.
● Not executed (only '-' is shown in the positioner display)
● Running
● Stopped
● Complete
If you run the test using the 'Start offline leakage test' button in the online dialog, the leakage
is measured at the position at which the positioner is currently located. The measured leakage
[%/min] is subsequently saved in the '11.LEAK' parameter. With the "Test area" parameter you
move the path by which the drive may move during this test.

9.2.2.12 Maintenance and diagnostics
Application
The sub-menu "Maintenance and diagnostics" is only available if the extended diagnostics has
been activated. You can then activate and parameterize the following extended diagnostics
parameters:
● Monitoring of dynamic control valve behavior 'b.\\DEVI' (Page 168)
● Monitoring/compensation of pneumatic leakage 'C.\\LEAK' (Page 170)
● Monitoring of stiction (slipstick) 'd.\\STIC' (Page 173)
● Monitoring of deadband 'E.\\DEBA' (Page 175)
● Monitoring the lower endstop ''F.\\ZERO' (Page 176)
● Monitoring the upper endstop 'G.\\OPEN' (Page 177)
● Monitoring the lower limit temperature 'H.\\TMIN' (Page 179)
● Monitoring the upper limit temperature 'J.\\TMAX' (Page 180)
● Monitoring of number of total strokes 'L.\\STRK' (Page 182)
● Monitoring of number of changes in direction 'O.\\DCHG' (Page 183)
● Monitoring the position average value 'P.\\PAVG' (Page 185)
Changes become effective as soon as the Transfer button is pressed.
