Installation

 Notes

Some targets pose 

specific

 problems for sensing distances. For example, targets with a stepped plane facing the sensor, a boundary line,

or rounded targets. Suggested sensor 

orientations

 for typical targets are below.

Recommended Sensor 

Orientation

Not Recommended

Sensor Programming

The sensor is programmed using three programming 

buttons

 and the LCD display or via RS422- and 

SSI-compatible

 serial interface

connections.
