28 TEMP - current temperature

Current temperature in the positioner enclosure. The sensor is provided on the electronic

printed circuit board.

The temperature display can be toggled between °C and °F by pressing the decrement

button.

29 TMIN - minimum temperature ("min/max pointer")

30 TMAX - maximum temperature ("min/max pointer")

The minimum and maximum temperatures inside the enclosure are continuously determined

and saved using a min/max pointer. They can be reset only in the factory.

31 T1 ... 39 T9 - number of operating hours in temperature ranges T1 to T9

Statistics about the duration of operation in different temperature ranges is maintained in the

device. An average of the measured temperature is taken every hour and the counter

assigned to the corresponding temperature range is incremented. This helps in drawing

conclusions about the past operating conditions of the device and the entire control valve.

The temperature ranges are classified as follows:

T1 T2 T3 T4 T5 T6 T7 T8 T9

Temperature range [°C] - ≥ -30 ≥ -15 ≥ 0 ≥ 15 ≥ 30 ≥ 45 ≥ 60 ≥ 75

≥ -30 < -15 < 0 < 15 < 30 < 45 < 60 < 75 -

Operating hours in temperature ranges T1 to T2

40 VENT1 - number of switching cycles of pilot valve 1

41 VENT2 - number of switching cycles of pilot valve 2

Both these counters sum up the control processes of pilot valves and are used to assess the

switching frequency.

42 STORE - save maintenance data

A save function can be initiated by pressing the increment button for at least 5 seconds.

The diagnostics data 7 to 18 is 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 command "Device-> Save

maintenance info". The data of the last maintenance data can be compared with the current

data using the PDM.
