Overview of the configured functions
Redundancy
Use this function to monitor two or three sensors with redundant measurements. The
arithmetic average of the two closest measured values is calculated and output as the
redundancy value.

The options depend on the
sensors connected
You can select a maximum of 3 different types
of sensor that output the same measured value.
Example for temperature redundancy
You have a pH sensor and an oxygen sensor at
inputs 1 and 2. Select the pH sensor as
Y1
and
the oxygen sensor as
Y2
.
