Description
23* Total valve travel
[0] to 99 · 10
7
, RES, ESC
Exponential reading from
9999 travel cycles on -
wards
Totaled full valve travel cycle
Can be reset to 0 in Code 36 – Std.
Note
The total valve travel is saved in a non-volatile memory after every
1000 full valve travel cycle.
24* LV total valve travel
1000 to 99 · 10

[1.000000], ESC
Exponential reading from
9999 travel cycles on -
wards
Limit value of total valve travel. If the limit is exceeded, the and
icons are indicated.
25* Alarm mode
0 to 3, [2], ESC
Switching mode of software limit switch alarms A1 and A2 when
activated (when the positioner is initialized).
1) 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
2) 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 ex -
plosion protection).
Note
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.
