User Interface
The user interface contains a light/dark operate switch, output
timer selector switch, interference protection switch, 8-turn
sensitivity adjustment knob with indication, and output LED
indicators for configuring and viewing the sensor’s operation
and status. A more complete description of each item is
described below.

Output and Stability Indicators
Two LEDs (green and orange) indicate a variety of conditions
to facilitate set-up and troubleshooting. The function of each is
described in the table below. Relevant output and stability
data are also shown.

Stability Output is an output feature provided by the 45FSL
sensor which monitors any changes or reduction of reflected
light levels during operation. Reflected light levels must reach
120% of the threshold required for normal operation to
achieve a “Stability Output.” If the sensor detects light levels
less than 120% of threshold 4 consecutive times then the
green LED starts flashing and remains flashing until a stable
light level is achieved (120%) (see illustration below).

8-Turn Sensitivity Adjustment
An 8-turn sensitivity adjustment (potentiometer) is built into the
sensor’s user interface for accuracy in detecting very small
objects or differentiating between colors.
Diffuse Set Up—Light Operate Mode
With target in position, turn sensitivity adjustment clockwise
until orange LED turns on (point A).
With no target in position the green and orange LEDs should
be off. Otherwise turn the sensitivity adjustment clockwise to
max or until orange LED turns on. If orange LED turns on,
then turn sensitivity adjustment counterclockwise until orange
LED turns off (point B).
Set sensitivity adjustment midway between points A and B.
Confirm sensor operation.
Transmitted Beam Set Up—Dark Operate Mode
With no target present, turn the sensitivity adjustment
clockwise to max until the orange and green LEDs turn on
(point A).
Green/orange LEDs should turn off. Otherwise turn sensitivity
adjustment counterclockwise until the green/orange LEDs turn
off. Turn sensitivity adjustment counterclockwise additional
one quarter turn and confirm sensor operation.
