PRODUCT OVERVIEW
The UVX 300-G-C sensor effectively detects UV luminescent materials and markers. Model UVX300-G-FGC is
specifically designed to detect gum used in the paper/envelope industry that contains a yellow/green fluorescent
tracer. The modulated UV light source in the UVX 300-G-C is directed toward a target and the visible light, resulting
from the fluorescence of the material, is reflected back to the sensor. When the reflected light level exceeds the
threshold the discrete output changes state. Due to the fast response of the sensor, it is suitable for use in high-
speed applications. The 50mm lens accessory allows for very small spot size for fine resolution applications. The
sensor provides both an analog and a discrete output. The analog output signal has a 0 to 5 V range with 20mV
resolution. A PLC or a computer can be used to process the analog output and monitor the status of the discrete
output signal.
The UVX 300-G is a reliable, compact sensor with long range sensing capabilities. Two seven segment displays
provide visual representation of the relative intensity from 00 to 99. Calibration feature and 3 LED intensity settings
provide for flexible operation over wide range of distances and materials.

QUICKSTART GUIDE
1. The display range is 00 through 99. 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. Apply power; sensor will initialize and perform its power up sequence.
4. The relative intensity will be displayed. By aiming the sensor away from any objects the display will indicate
00. Aim the sensor at a white piece of paper and the display will indicate an intensity measurement. Move
the paper further away from the sensor to decrease the intensity level.
5. Various adjustments may be made to increase or decrease sensitivity; refer to the Selections Calibration
Adjustment and LED Intensity Level. Refer to Section: Threshold, to after threshold setting.
6. 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 99. 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.
Calibration Adjustment
The calibration feature allows the displayed measurement to be adjusted to the desired value by the user.
Adjusting the measured value:
1. Place target in sensor’s field-of-view. The sensor will display the current reading.
2. Press either key (for less than 3 seconds); while the current reading is displayed the value
Is flashed slowly indicating that the sensor is in the adjustment mode.
3. Press T/+ to increment the reading and P/- to decrement the reading.
4. Stop pressing either key and sensor returns to normal operating mode in 3 seconds.
Note:
 While adjusting the reading, when a limit is reached the display flashes at a faster rate.
 The selected gain is stored in memory and is retained when power is removed.
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 (Local Lock) indication on the display.
Programmable Parameters

Document no. 10010404 Rev 1.6
All adjustments made to these parameters are stored in memory and are retained when power is removed. To
enter programming mode press and hold the P/- key for several seconds, the current threshold setting will be
displayed. Press and release the P/- key to scroll through the various settings. Press and release the T/+ key to
change a particular setting. Press and hold the P/- for several seconds to return to the normal intensity display
mode. The user programmable items are described below.
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 hysteresis 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.
To adjust the threshold, enter programming mode, press and hold the P/- key for several seconds, the
current threshold setting will be displayed. Press and release the T/+ key to increase the threshold level,
to decrease the threshold level, continue to hold the T/+ key until the value approaches 99 then wraps
around to 00.
LED Intensity Level (U)
The LED intensity is indicated on the display as U1, U2 and U3 for low, medium and high intensity. Press
and release the T/+ key to toggle through the 3 intensity levels. The default setting is U2, medium intensity.
Hysteresis Level (H)
The hysteresis setting is indicated by H0 through H9. The hysteresis level is how far below the threshold
the signal must fall to de-activate or un-detect. The hysteresis can be set from 0 to 9. For example, if the
threshold is set at 25 and the intensity exceeds 25, the sensor will detect and activate its output. With the
hysteresis set to 5, the signal must drop to 20 to un-detect. This feature is useful in cases where there may
be variation within a target that might cause the intensity to drop below the threshold slightly; the hysteresis
allows the output to remain activated until the level drops significantly. Press and release the T/+ key to
change the hysteresis setting. The default setting is 2.
Discrete Output Configuration
This setting allows the user to select either normal open (no) or normally closed (nc) configuration. The
normally open configuration de-activates the output during normal un-detect operation, and activates the
output upon detect. The normally closed configuration activates the output during normal un-detect
operation, and de-activates the output upon detect. Press and release the T/+ key to toggle through the
selections. Default is normally open.
Extend Output Pulse (P)
This feature allows extending the minimum length of time that the discrete output remains active following
target detection. The sensor response can be in the 100uS (microsecond) range, i.e. a target can move
through the sensing range in 100uS and the discrete output would active for only that duration. A slower
acquisition system (PLC) may not sample its inputs at a fast enough rate to capture the signal. The discrete
output pulse can be extended from 0 to 90mS (milliseconds) in 10 mS increments as indicated by P0 though
P9 on the display. Press and release the T/+ key to toggle through the selections.
Null Offset (nu)
NOTE: Always perform the null function when installing or removing optional lens or changing LED
intensities.
The null feature allows the sensor to be “zeroed”. For example, when the target is not in view and there is
a background that causes a reading above zero, the null feature allows this level to be subtracted out,
allowing the display to indicate 00. Press and hold the T/+ key to null the sensor. The display will flash the
value that is being subtracted. To set the sensor back to a true zero, aim the sensor away from any target
and repeat the null process.

Teach Function
The teach function allows the user to set the threshold by placing a representative target located at the
required distance and allowing the sensor to determine the optimum LED intensity and setting of the
threshold level.
1. Press and hold the T/+ key for several seconds until the yellow led flashes.
2. Place the target at the appropriate distance from the sensor and press the P/- key. The display will
flash 3 times and the sensor will adjust the LED intensity level to achieve reasonable signal level.
The green LED will flash.
3. Remove the target and press the P/- key. The display will flash 3 times.
4. Exit the teach function and return to the normal operating mode by Pressing the T/+ key for several
seconds.
When in the teach mode the LED flashes constantly, yellow, green or red. Yellow indicates that the sensor
is ready to be taught the Detect level. Green indicates that the sensor is ready to be taught the Undetect
level. Red indicates that the last attempt to teach resulted in an error. If the error occurred during the
teaching of the Detect level then the signal intensity was less than 01. If the error occurred during the
teaching of the Undetect level, then the signal intensity was greater than or equal to the threshold level. In
either case, repeat the teach function to properly set the levels.
Output Signals
Discrete Output
The discrete output is a PNP/NPN configuration allowing the user to provide a load on this output that is
either pulled high to VDC or low to ground. The sensor monitors this level and automatically determines
whether to operate the PNP/NPN driver. This output is typically connected to a PLC. The output remains
active as long as the intensity level exceeds the threshold, in high-speed applications it may be useful to
use the Extend Output Pulse feature to lengthen the signal duration to meet acquisition requirements of the
PLC.
CAUTION: The discrete output must not be connected to outputs from other sensors (i.e. outputs from
multiple sensors must not be connected in parallel). Parallel connections may damage
sensor output circuitry.

P/-
T/+
Analog Output
The analog output is 0-5V with 20mV resolution (8-bit). Any standard analog input channel typically
available on a PLC may monitor this output. The analog output signal is useful in applications where simply
triggering on the threshold is insufficient. For example, constant real-time monitoring of intensity in process
allows minor fluctuations or trends to be detected permitting corrective action to be taken.
Remote Lock/Unlock Input
The remote lock feature allows the user to lock out the local controls (keys) to prevent operators from
making unauthorized adjustments. This signal line must be connected to VDC to lock the sensor. This line
may be left unconnected if the lock feature is not used. While the sensor is locked, pressing either P/- or
T/+ will result in rL (remote Lock) indication on the display.
