Adjust the Sensor Sensitivity
Follow these steps to set the detection limit for the sensor.
1. With a stationary substrate (no adhesive) under the sensor at the proper
focal distance of 25−30 mm (0.98−1.18 in.), press
and
at
the same time. The sensitivity is set automatically to default level based
on the reading from the substrate.
2. Test the sensitivity setting by positioning the substrate with the adhesive
under the sensor. Check that the glue LED comes on.
3. Run the product through the machine normally (with adhesive) and
check the monitor screen on the controller. Check that adhesive is
shown reliably in the correct location.
4. Modify the sensitivity to obtain a consistent reading from the sensor:
S If the monitor screens shows a broken bead, check the sensor
alignment and, if necessary, increase the glue sensitivity by pressing
repeatedly until a solid bead is displayed.
S If the monitor screen incorrectly shows glue on the substrate where
no glue is found, decrease the glue sensitivity by repeatedly
pressing
until the glue pattern displays correctly.
Frequency
The sensitivity adjustment procedure should be performed under the
following conditions:
a. During initial installation.
b. After a product change.
c. After the adhesive pattern changes.
d. After a significant change in adhesive add-on.

NOTE: STO and Gun-to-Trigger Offset (GTO) are critical to the proper
function of the control system. These settings essentially inform the
LogiComm engine and the touch-screen panel about the physical set-up of
the devices in relation to each other.
STO is used to establish the location of the bead image on the screen. The
end of the STO distance tells the engine where to begin monitoring the
sensor input. The inspection zones and sensor mask regions are also
based on this distance.
GTO is used by the pattern controller to set distance from the center line of
the gun nozzle to the center line of the trigger lens.

Optimum Focal Distance
The optimum viewing distance from the end of the sensor to the substrate is
28 mm (1.10 in.).
Adjust the Sensor Lens
Use this procedure to adjust the focus of the sensor lens.
S Slowly move the GD-200 sensor up and down until the light on the
substrate is clear. See 1 in Figure 14.
S Slowly move the GD-200F sensor’s fiber optic cable bracket up and
down until the light on the substrate is clear.
NOTE: When the lens is properly focused, the light on the substrate
appears as a perfectly clear circle with scattered black spots. The black
spots are actually the photo receptors within the lens that detect light
reflected back from the substrate.
NOTE: You may want to wear sunglasses if the light from the sensor is too
bright, making it difficult for you perform this task.

Appendix A
Sensor Specific Screens
When the sensor is being operated with the LogiComm control system, you
can access the sensor specific screens from the Sensor menu screen in the
touch-screen panel.
Three inspection methods are used to verify products:
S Template verification setting
S Accumulated bead length
S Maximum gap measurements
The following screens are examples of each inspection type.
Template Verification Setting
When initiated by the operator, the engine learns good patterns by
measuring good products (the number of products is programmable). From
this learned data and the tolerances set by the user, a comparison template
is stored in the verification accelerator board.
When verifying normal bead data, sensors are sampled on every encoder
pulse and compared to the corresponding template values. If the data
compares favorably to the template data, the product is considered good. If
product data does not match the template within the set tolerance, it is
queued for ejection.
See Figures A-1 and A-2 for examples of a good template setting and a
defective template setting.

Accumulated Bead Length Setting
The accumulated bead length verification method provides an analysis tool
to monitor too much or too little adhesive on the substrate by allowing the
user to set upper and lower limits for the total length of glue in a designated
area called the measurement zone. A typical application is for the detection
of excessive glue that could cause a squeeze-out. A squeeze-out occurs
during compression when excess glue seeps out of the glue flap, causing
the products to stick together.
In using this method, the user designates the measurement zone by
entering the start position and length of the measurement zone. The user
then sets an upper and lower limit to the total amount of measured glue
bead over the zone. During the inspection process, the LogiComm system
adds together each bead segment in the specified region, without
consideration of the exact location of the segments. The product is
determined to be defective if the total length of glue bead exceeds the upper
limit or is less than the lower limit.
See Figures A-3 and A-4 for examples of a good accumulated bead length
setting and a defective accumulated bead length setting.

5. Measurements of the actual bead
Maximum Gap Setting
The maximum gap verification method provides an analysis tool that
inspects for gaps in the adhesive bead that exceed a user-specified
maximum. A typical application for maximum gap verification is for the
inspection of wheel-applied glue where railroad tracks, or broken beads are
common, and where the critical quality control measure is to ensure that
gaps in the glue are not excessive in order to ensure bond integrity.
In using this method, the user designates the measurement zone by
entering the start position and length of the measurement zone. The user
then sets a maximum gap length limit. During the inspection process, the
LogiComm system inspects over the user-specified region, comparing each
gap in the adhesive bead to the maximum limit, and without consideration of
the exact location of the gaps and segments. The product is determined to
be defective if any gap exceeds the maximum gap limit.
See Figures A-5 and A-6 for examples of a good maximum gap setting and
a defective maximum gap setting.
