The minimum and maximum temperatures within the enclosure are
constantly determined and saved as with a slave pointer. This
value can only be reset in the factory. In order to switch over the
temperature display between °C and °F, press the
least 5 seconds in order to initiate a save function. The values of
the diagnostics parameters Diagnostic value '8.WAY - Determined
travel' (Page 212) to Diagnostic value '11.LEAK - Leakage test'
(Page 212) and Diagnostic value '21.P0 - Potentiometer value of
lower endstop (0%)' / '22.P100 - Potentiometer value of upper
endstop (100%)' (Page 218) to Diagnostic value '28.SSUP - Slow
step zone UP' / '29.SSDN - Slow step zone DOWN' (Page 220)
are saved in the non-volatile memory as 'data of last maintenance'.
This diagnostics data contains selected values whose changes
can give information about mechanical wear and tear of the valve.
This function is normally operated through the PDM, menu com-
mand 'Diagnostics-> Save maintenance information'. The data of
the last maintenance operation can be compared with the current
data using SIMATIC PDM.

This value specifies the prediction of the controller for the up
(PRUP) and down (PRDN) movements.

troller data (Page 110).

When the positioner is in "Automatic" mode, statistics are continu-
ously maintained regarding the duration for which a valve or a flap
is operated in a particular section of the travel range. The entire
travel range is divided into 8 sections from 0 to 100 %. The posi-
tioner records the current position continuously and increments the
runtime meter assigned to the corresponding travel range every
hour. This helps in drawing conclusions about the past operating
conditions and especially in assessing the control properties of the
control loop and the entire control valve.
