Overview

The sensor has an LCD display and 3 push buttons, which control all programming

functions. Serial interface programming can also be accomplished, via SSI or RS422.
Four status indicator LEDs on the sensor front/top provide ongoing status of power and

outputs.

• Escape: Cancels active function and switches to one menu level above (Figure

7) without saving new values

• Important: Both arrows must be pressed simultaneously. Previous value is

unchanged.

The sensor has a 2-line LCD display and 4 LED indicators for ongoing indication of

sensing status: Power ON, Alarm, and Outputs 1 and 2.
In Run mode, the current measured value is displayed in the top line of the sensor’s

display, in millimeters or hundredths of an inch, as selected.

Sensing Options

Sensing Beam. The sensor uses an infrared Class 1 laser for sensing, and a visible red

Class 2 laser (or Pilot laser) for alignment. Both lasers are aimed at the identical target

spot. The laser beams are collimated to focus a compact spot, even at long sensing

distances (see Figure 2).
