ABB AC500 V3 - Use of analog inputs as digital inputs; Internal data exchange

The following measuring ranges can be configured Ä Chapter 1.6.2.2.2.6 “Parameterization”
on page 444
Ä Chapter 1.6.2.2.2.9 “Measuring ranges” on page 449:
Voltage 0 V...10 V with differential inputs, 2 chan-
nels used
Voltage -10 V...+10 V with differential inputs, 2 chan-
nels used
The function of the LEDs is described under Displays Ä Chapter 1.6.2.2.2.7 “Diagnosis”
on page 447.
In order to avoid error messages or long processing times, it is useful to configure unused
analog input channels as "unused".
Use of analog inputs as digital inputs
Several (or all) analog inputs can be configured as digital inputs. The inputs are not galvanically
isolated against the other analog channels.
