Test of software limit switch alarms A1 and A2 as well as of fault
alarm contact A3.
If the test is activated, the contact is switched five times.

ment between travel/angle position and output signal i based on
CLOSED position.
The operating range (see Code 8) of the valve is represented by the
4 to 20 mA signal. Values exceeding or falling below the limits 2.4
and 21.6 mA can be indicated.
When the positioner has not been mounted (set point smaller than
3.6 mA), the signal is 0.9 mA and 3.8 mA the positioner has not
been initialized. When YES is set in Code 32, the position transmit-
ter issues the value as per Code 30 during initialization or zero cali-
bration. When No is set in Code 32, 4 mA is issued during a run-
ning calibration.

the operating range.
The momentary valve position is used in initialized positioners local-
ly as the start value (bumpless changeover to the test mode). When
testing by software, the entered simulation value is issued as the po-
sition feedback signal for 30 seconds.
