D12E Sensors mount directly to a standard 35mm DIN rail, or may be through-hole mounted using the supplied mounting bracket and
M3 x 0.5 hardware.

Running and Programming the D12 Expert

Run Mode

Normal operation of the D12 Expert is called Run mode. During Run mode, the seven-segment LED display becomes a moving dot
signal strength indicator (see

Overview

on page 1). When the light and dark sensing conditions are analyzed by the sensor during

TEACH mode, the sensor’s microprocessor automatically distributes the range of signal strength seen in the light condition evenly be-
tween the seven LEDs. This display gives a true reading of the relative signal strength for the current application, and is a useful indicator
of changing sensing conditions.
Maximum Sensitivity. D12 Expert sensors are factory set for maximum sensitivity. Use the following TEACH mode procedure at any
time to return the sensitivity to its maximum setting.
Following the TEACH mode procedure (see

TEACH-Mode Programming

on page 6), teach the following two conditions:

1. No light reaching the receiver. One easy way to do this is to disconnect the emitter and/or receiver fiber at the sensor.
2. Maximum light reaching the receiver. The best way to do this is to pipe the light from the sensor’s emitter port directly into the

receiver port, using a short individual fiber. If this is not convenient, return the greatest amount of light possible to the receiver by
using a reflective target at close range (diffuse mode sensing) or by bringing the sensing end tips together (opposed mode sens-
ing).

Factory Default Settings. D12E and D12E2 sensors are factory set at the following defaults: maximum sensitivity, light operate output
and pulse stretcher OFF. Perform the procedures on the following pages to program your own settings. Unlike competitive sensors, the
D12E has no exposed switches or adjustments.
