Switching mode of software limit switches alarm A1 and A2 in
responding state (when positioner initialized).
1) Explosion-protected version according to EN 60947-5-6
0: A1 ≥ 2.1 mA
1: A1 ≤ 1.2 mA
2: A1 ≥ 2.1 mA
3: A1 ≤ 1.2 mA
2) Version without explosion protection
0: A1 R = 348 Ω
1: A1 Non-conducting A2 Non-conducting
2: A1 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 ≤ 1.2 mA signal (Ex) or non-conducting
(without explosion protection).
Displaying or changing the software limit value A1 in relation to
the operating range.
Setting has no effect when an inductive limit switch has been in-
stalled.
Displaying or changing the software limit value A2 in relation to
the operating range.
Testing the software limit switches alarm A1 and A2 in addition
to the fault alarm contact A3.
If the test is activated, the respective limit switches five times.
