Configuration Guide (AADvance Controller)

Threshold Values for Digital Inputs

The module determines the channel state and the line fault status by comparing the

channel input voltage with defined threshold values. You can define your own

threshold values or use a set of default values. The values you choose for the module

are inherited by each channel; you can define different thresholds for individual

channels later.

An indeterminate region is defined between the closed and open status to allow for

marginal faults in the external wiring or sensor.

Note: When the system is operational you should change these values only through

an on-line update.

The AADvance controller provides hysteresis on the thresholds for increasing and

decreasing values to prevent chatter. The Workbench updates the reporting values

during every application cycle.
