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
1: A1 ≤ 1.0 mA
2: A1 ≥ 2.2 mA
3: A1 ≤ 1.0 mA
2) Version without explosion protection
0: A1
1: A1
2: A1
3: A1
When a positioner has not been initialized, the software limit switch-
es 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.
Alarm A1 responds when the value falls below the limit.
Software limit value A1 is displayed or can be changed in relation
to the operating range.
The setting has no effect when an inductive limit switch is installed.
Alarm A2 responds when the value exceeds the limit.
Software limit value A2 is displayed or can be changed in relation
to the operating range.
