11.3.4.10 11 Monitoring/compensation of pneumatic leakage
This fault message appears if a leakage is present. For additional information, see Monitoring/
compensation of pneumatic leakage 'C.\\LEAK' (Page 170).
11.3.4.11 12 Monitoring of stiction (slipstick)
If the stiction of the control valve increases during operation or if an increasing number of
Slipjumps is detected, "d1.LIMIT" could be exceeded and result in this fault message.
11.3.4.12 13 Monitoring the lower limit temperature
This fault message appears when the lower limit temperature thresholds are undershot.
11.3.4.13 14 Monitoring the upper limit temperature
This fault message appears when the upper limit temperature thresholds are overshot.
11.3.4.14 15 Monitoring the position average value
This fault message appears when a position value calculated after the expiry of a comparison
interval deviates from the reference value by more than the configured thresholds.
11.3.4.15 16 Monitoring the plausibility of values for the partial stroke test
This error message is triggered if, when starting a partial stroke test, the plausibility check of the
"A1.STPOS", "A3.STRKH" and "A4.STRKD" parameters was not successful.
11.3.4.16 17 Monitoring of pressure sensor module
If the pressure sensor module is activated and defective, this fault message is displayed.
11.3.4.17 18 Monitoring low limit of supply pressure (PZLIM)
If the supply pressure is below the configured low limit (PZLIM), this alarm message is
displayed.
11.3.4.18 19 Monitoring specific limits of supply pressure
If the supply pressure lies outside the positioner specification from 1.4 bar to 7.0 bar, this alarm
message is displayed.
