Press and release the Learn/Gain button (6) to change the gain of the
input amplifier. Each time the button is pressed, the gain is changed.
The
Auto/Gain
LED (3) will blink to show what gain has been
selected. If the button is held down, the gain will increase
automatically after each LED „blink‟ pattern. Refer to Table 2. The
larger the gain, the weaker the signal being picked-up. Using a large
gain for a strong signal is not recommended since the input will
saturate.
6.0 ADVANCED FEATURE (TARGET POLARITY)
The input circuitry can be set to optimally work with two different target
types: a reflective (white, shiny) target on a mostly non-reflective (black,
dull) background or a non-reflective (black, dull) target or a mostly
reflective (white, shiny) background. These will be referred to as a white
target or a black target. When the unit is first turned on, the
On Target
LED (1) will indicate which target type the sensor is set up for. While the
Laser On
LED (2) is blinking, the
On Target
LED will be on for a white
target or off for a black target. The unit will still work when set up for the
“wrong” target type, but it won‟t have as great a range. When set for a
white target, the unit triggers on the black to white transition. When set
for a black target, the unit triggers on the white to black transition.
To change the setting, move the Polarity switch (5) to the left (positive
pulse) for a white target or to the right (negative pulse) for a black target.
Turn the Sensitivity Adjust knob (7) to
Max
. Press and hold the Learn/
Gain button (6) until the
Auto/Gain
LED (3) blinks.
7.0 AIMING THE LASER
The proper operation of the Laser Sensor is dependent upon the alignment
to and reflectivity of the target. In order to aim the beam it is necessary to
stand behind the sensor and view the target along the plane of the beam.
