NPN Hookup PNP Hookup Conversion from Current to
Voltage Output
*NOTE: The bare shield wire should be connected as follows:
1) If the sensor housing is mounted so that it is in continuity with both the machine
frame and earth ground, connect the bare wire (also) to earth ground.
2) If the sensor housing is mounted so that it is insulated from the machine frame,
connect the bare wire to -V dc (together with the blue wire).
3) If the sensor is mounted so that it is in continuity with the machine frame, but
not with earth ground, do not connect the bare wire (i.e. cut off the bare wire).
**NOTE:
For best results, install a small
amount of capacitance (e.g., 0.1µF)
in parallel with the load resistor

Modes
The L-GAGE Laser Gauging Sensor operates in two modes: TEACH (or programming)
and RUN.
TEACH-Mode Programming
Response Speed
Use the Speed push button to toggle between the three response speed settings. The
combination of indicator lights (Fast and Slow) will tell you which of the three is
selected:
