Automatic Tuning
Automatic Tuning will capture the capabilities of the end user. This will
automatically assign a threshold level based on light levels during tuning.
1.
Press the
Tune
button once while breaking the beam.
a.
The display will read
St 1Pnt.
2.
Press the
Tune
button once again with nothing breaking the beam.
a.
The display will read
St 2Pnt
.
3.
Setting is complete.
NOTICE
Start with auto-tuning then adjust with minute-tuning if
auto-tuning fails or if small adjustments are required.
NOTICE
Steps One and Two may be reversed. The larger
of the two light levels will be used for this setting.
The threshold will be set based on this.
Minute Tuning
Minute Tuning allows you to fine tune the threshold level.
1.
Press the '+' or '-' button until you find the appropriate threshold.
a.
'+' will increase the threshold value. The higher the number, the
closer to the emitter you must be to break the beam.
b.
'-' will decrease the threshold value. The lower the number, the
farther from the emitter you must be to break the beam.
A higher threshold level typically means that the activation occurs closer to
the sensor as compared to a lower threshold level.

nEAr Err
Light level between points
1 and 2 are too small.
•
Re-tune the system.
•
Mount the sensor closer to the surface
that is breaking the beam.
ovEr Err
Light level is too high.
•
Re-tune the system.
•
Increase the tuning level.
•
Mount the sensor farther from the surface
that is breaking the beam.
Lo Err
Light level is too low.
•
Re-tune the system.
•
Increase the tuning level.
•
Mount the sensor farther from the surface
that is breaking the beam.
