Quick Start Guide
1.
The display range is 00 through 50. The decimal points indicate the LED intensity level.
The RED LED above the display indicates that the intensity level exceeds the threshold setting.
2.
Connect cable to power supply observing correct polarity. Reference wiring diagram.
3.
NOTE: The remote lock input, pin 5 on the connector (gray wire), must be left unconnected or pulled
to ground to allow operation of keys on sensor.
4.
Apply power; sensor will initialize and perform its power up sequence.
5.
The relative intensity will be displayed. By aiming the sensor away from any objects the display will
indicate 00. Aim the sensor at your target or a white piece of paper and the display will indicate an
intensity measurement. Move the target further away from the sensor to decrease the intensity level.
6.
Press and release either key located below the display to view the current threshold setting. While the
current threshold is shown on the display, press the + or – key to increase or decrease the setting,
then wait several seconds for the sensor to return to the normal intensity display mode.
7.
User programmable parameters are discussed in detail in the following sections.
Operation
Power up
Upon power up, the sensor initializes by turning on all segments on the display and sequencing through red,
yellow and green on the status LED located above the display.
Intensity display mode
During normal operation the sensor display will indicate the relative intensity of a target within its field of
view. The range of the relative intensity display is 00 through 50. The decimal points on the display indicate
the LED output intensity. No decimal points indicate low, one decimal point indicates medium and two
decimal points indicate high intensity.
Threshold
When the relative intensity level exceeds the threshold setting the red status LED will turn on and the
discrete output will activate, indicating detection of the target. When the relative intensity level drops below
the threshold (as determined by the hysterisis setting), the red LED will extinguish and the discrete output
will de-activate. The threshold setting allows the user to select the detection level. The default setting is 15.
While the current threshold is shown on the display, press the + or – key to increase or decrease the setting,
then wait several seconds for the sensor to return to the normal intensity display mode.
Local Lock
The local lock feature allows the sensor to be locked out, preventing adjustments by unauthorized personnel.
To lock the sensor, press the
P/-
and
T/+
buttons for 3 seconds until
LL
is displayed. To un-lock the sensor,
press the
T/+
and
P/-
for 3 seconds until
LL
is not displayed. While the sensor is locked, pressing either
P/-
or
T/+
will result in
LL
(
L
ocal
L
ock) indication on the display.
