6.6.1
Assignment of the Switch Outputs (digital I/O)
Switching outputs “Error 1” and “Error 2” of the “Digital I/O” terminal block can be indi-
vidually assigned to different errors and thresholds.
Per default, “Error 1” is assigned to intensity errors (F1, peak too high or too low), and
“Error 2” corresponds to the signal being outside the measuring range (F2).
6.6.2
Limit Value Settings
You can also use the “Error 1” and “Error 2” switching outputs to monitor threshold val-
ues. In this case, enter lower and upper limit values (in mm).
6.6.3
Switch Threshold of the Error Outputs
The switching logic for errors or out-of-range results can be set to
high active
or
low
active
.

Selecting the switching logic is different from selecting a level by using a screw terminal
bridge on the front of the controller, see Chap.
.
You can set the screw terminal voltage level to 5 V or 24 V.
