time in the case of time-critical measurements. Then gently clean the face of the sensor
cable’s E2000 connector. Only use pure alcohol and fresh lens cleaning tissue to do this.
Then repeat the darkness correction. If nothing changes, the sensor cable can also have
become damaged or the fibre connector lying in the controller may become soiled.
Change the sensor cable or submit the whole system for checking.
You can adjust the warning threshold if necessary in the event of contamination by an
ASCII command (permissible deviation in %); the factory setting is 50 %, see Chap.
.
The warning threshold is stored specific to the setup.

Distance Measurements
Align the sensor vertically to the target object.
Then, move the sensor (or the target) closer, until you more or less reach the start
of measuring range for your sensor.
Once the object is within the sensor's measuring range, the
Range
LED (green or yellow) on the front of the controller will light up. Or, observe the
video signal.
Name
State
Description
LED 1
Intensity
Red
Intensity too high, first peak in saturation
Yellow
Intensity too low, first peak below recognition threshold
or no peak above the recognition threshold
Green
Signal ok
LED 2
Range
Red
No peak within the linearized (or masked) range
Yellow
Peak in the midrange (47.5 … 52.5 %)
Green
OK, at least one peak within the linearized (or masked)
range
Error 1
Intensity = 1
Intensity too high or too low (warning, if intensity is satu-
rated or below recognition threshold)
Error 2
Out of range = 1 No peak within the linearized range
