User calibration

The analog inputs and outputs are fac-
tory-calibrated.
A system-related user calibration can com-
pensate for long cables, small wire
cross-sections or tolerances of measuring
transducers and actuators. The calibration is
similar in principle to a scaling. The gradi-
ent and zero shift are automatically calcu-
lated by the controller.
Note: The function A.21.1-2 allows the
controller to be reset to factory-calibration
settings.
11.1 Calibrating analog inputs
4
Connect signal source at the input.
Zero
4
Enter menu item Zero depending on the
analog input and signal type, e.g.
A.20.1.9 for Analog input AI1 and
Pt 100 (see section 15.2).
4
Set the signal source to the initial value.
If the input value is within the range that
can be calibrated, the selection bar is
displayed.
4
Press the enter key (
value. The zero point is calibrated.
End value
4
Enter menu item End depending on the
analog input and signal type, e.g.
A.20.1.10 for Analog input AI1 and
Pt 100 (see section 15.2).
4
Set the signal source to the end value.
If the input value is within the range that

11.2 Calibrating analog outputs
4
Connect a precision measuring instru-
ment at the output.
Zero
4
Enter menu item Zero depending on the
analog output and signal type, e.g.
A.20.5.1 for Analog output AO1 and
mA signal (see section 15.2).
4
Set the output signal using the cursor
keys ( and
the output value is within the range that
can be calibrated, the selection bar is
displayed.
4
Press the enter key (
value. The zero point is calibrated
(display: 0.0 %).

4
Enter menu item End depending on the
analog output and signal type, e.g.
A.20.5.2 for Analog output AO1 and
mA signal (see section 15.2).
4
Set the output signal using the cursor
keys ( and
If the output value is within the range
that can be calibrated, the selection bar
