Parameter – Readings/
values [default setting]
Description
23* Absolute total valve travel
[0] to 99 · 10 7 , YES, ESC
Exponential reading from
9999 travel cycles onwards
Totaled full valve travel cycle
Can be reset to 0 in Code 36 – STD and Code 36 – DS.
Note: The total valve travel is saved in a non-volatile memory
every 24 hours.
24* Total valve travel limit
1000 to 99 · 10
7
[1.000000], ESC
Exponential reading from
9999 travel cycles onwards
Limit of total valve travel limit
'Total valve travel exceeded' message is generated depending on
selected status classification if the limit is exceeded.
Note: The 'Total valve travel exceeded' message has the default
status classification 'Maintenance required'. This classification can
only be changed in the operator software (e.g. TROVIS-VIEW).
25* Alarm mode
0, 1, [2], 3, ESC
Switching mode of software limit switch alarms A1 and A2 when
activated (when the positioner is initialized).
Explosion-protected version according to EN 60947-5-6
0: A1 ≥ 2.2 mA A2 ≤ 1.0 mA
1: A1 ≤ 1.0 mA A2 ≤ 1.0 mA
2: A1 ≥ 2.2 mA A2 ≥ 2.2 mA
3: A1 ≤ 1.0 mA A2 ≥ 2.2 mA
Version without explosion protection
0: A1 R = 348 Ω A2 non-conducting
1: A1 non-conducting A2 non-conducting
2: A1 R = 348 Ω A2 R = 348 Ω
3: A1 non-conducting A2 R = 348 Ω
When a positioner has not been initialized, the software limit
switches always register the signal as in the state of no response.
If there is no mA signal at the terminals 11/12, the software limit
switches both switch to ≤ 1.0 mA (Ex) or non-conducting (without
explosion protection).
Note: The fault alarm output always switches to ≤ 1.0 mA/non-
conducting in case of a fault; it has ≥ 2.2 mA/R = 348 Ω when
there is no fault.
