Product Overview
The UVX tin-side detection system employs our field-proven, UVX™ - based sensor, to accommodate the
special requirements for reliable tin-side glass detection. The system consists of a Control Unit,
Optical Unit, 24VDC power supply and interface cable.
The Control Unit provides a display with a 00-99 range and access to set-up parameters and threshold
adjustment. The output of the Control Unit is a discrete, NPN/PNP that indicates when the signal level
exceeds the threshold setting which occurs when viewing the tin-side. The Control unit may be mounted
to provide easy access to the controls and the display.
The Optical Unit is mounted at approximately 5-10mm from the surface of the glass. A green LED
indicates that the Optical Unit is powered. The enclosure provides 4 mounting holes (or 2 for the UVX
tin-side mini) for user–supplied bracket /hardware. The Optical Unit also acts as a shroud over the
sampling area to minimize exposure to the UV light source and prevent interference from ambient light.
The light source is a special LED with a limited service life. The system employs a remote enable line
that allows the user to activate the LED and read the result from the sensor in a short sample period
typically 5-10 mS greatly extending the life of the LED.
The system 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 during the short sample period previously described.

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. The green LED on
the Optical Unit indicates power.
Intensity Display Mode
During normal operation the sensor display will indicate the relative intensity of a target within
its field of view. The display is useful primarily during set-up and adjustment of the sensor.
During normal operation where there is movement of the samples/targets, the display is not
generally useful since the display update rate is about 3x/sec. 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 a 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
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)
NOT USED
System Operation
The purpose of the UVX Tin-side detector system is to identify the tin-side of float glass by
projecting the UV light source onto the target surface. When the tin-side is present the surface
will emit light in the visible spectrum. The receiver optics measures the intensity of the visible
light and when the level exceeds the user adjustable threshold setting the discrete output will
activate.
The UVX Tin-side detection system is typically controlled by a PLC. Due to the limited service
life of the light source it is necessary to use the PLC to initiate and control the measurement
process. A typical sequence may be set-up as follows:
1. A separate proximity sensor detects the presence and proper positioning of a sample
pane. Its output is connected to the PLC.
2. The PLC activates the UVX LED Enable line by connecting this line to sensor ground.
3. The PLC waits 5-10mS, and then reads the UVX discrete output to determine if the tin-
side is present. The PLC deactivates the UVX LED Enable line by disconnecting this line
from sensor ground.

Installation
The Optical Unit contains the light source and receiver optics. The unit is to be mounted 5-
10mm above the glass surface. During installation be careful not to damage the optics.
1. Read the Caution statements in this manual regarding the UV light source prior to
installation.
2. Connect an earth ground to the stud on the Optical Unit using minimum 20 AWG wire.
3. Position the Optical Unit to be parallel to the glass surface at a distance of 5-10mm. For
optimum performance, the distance should be adjustable.
4. There should be nothing on the other side of the glass (within 300mm), or the surface
should be matte black to minimize reflections from the sensor light source and ambient
lighting.
5. The UVX Control Unit may be mounted in an easily accessible area near the Optical Unit
to allow adjustments of sensor parameters.
6. Connect the cable between the Optical Unit and the Control Unit.
7. Connect the Control Unit wiring to the power source and PLC. If necessary, connect LED
Enable (yellow wire) to sensor ground to activate the light source. Always disconnect the
jumper to disable the light source when not in use.
8. Use a piece of white paper on the glass to visually verify that the light source is on. The
optical brighteners in the paper will produce a bright blue light spot.
9. Remove the paper and slide a glass sample, with the tin-side toward the Optical Unit,
into position.
10. The display will indicate the signal level due to the interaction between the UV light and
tin-side surface which produces visible light. Adjust the distance between the Optical
Unit and the glass surface to obtain the highest reading.
11. Remove the glass and place the air-side toward the Optical Unit. The reading should be
much lower than that of the tin-side. Adjust the threshold to the value between these
two readings.
12. Remove the jumper and test the system.

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.
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.
LED Enable
The LED Enable feature allows the user to activate the LED only when a measurement is
necessary, minimizing the on time of the LED and extending its service life.
IMPORTANT:
This line is to be left open to disable the light source; the light source should be disabled at all
times other than the short cycle required to make a measurement.
It is recommended that the typical measurement cycle be limited to 5-10mS (milliseconds).
