RUN 3 3 RUN
ESC ESC
Testing the software limit switches alarm A1 and A2 as well as
the fault alarm contact A3.
If the test is activated, the respective limit switches five times.

ESC
Operating direction of the position transmitter; indicates how the
travel/angle position is assigned to the output signal i, based on
the closed position.
The operating range (see Code
8 ) of the valve is represented by
the 4 to 20 mA signal.
When a positioner is not connected (reference variable less than
3.6 mA), the signal is 0.9 mA and when the positioner has not
been initialized 3.8 mA.
30* Fault alarm ix
3)
[No] HI LO
ESC
Used to select whether faults causing the fault alarm contact to
switch should also be signaled by the position transmitter output
and how they should be signaled
HI ix = 21.6 mA or LO ix = 2.4 mA
31* Position transmitter test
3)
–10.0 to 110.0 [default
value is the last indicated
value of the position
transmitter]
% of the operating range
ESC
Testing the position transmitter. Values can be entered in relation
to the operating range.
The current actual value is used in initialized positioners locally
as the start value (bumpless changeover to the test mode). On
testing over software, the entered simulation value is issued as
the position feedback signal for 30 seconds.
3)
Analog position transmitter: Code 29/30/31 can only be selected if the position transmitter (optional) is installed.
