System Overview This manual describes the installation, connection, setup, and operation ofthe GD500‐2 controller and GD500 sensor when used with the LogiComm� control system.

The GD500‐2 Bead Detection System includes a sensor configuration that isspecific for corrugated machines.

The GD500 sensor monitors liquid adhesive applications, such asside‐seam, wheel‐pot, or extrusion applications, for too much or too littleadhesive. A keypad and an LCD display on the GD500‐2 controller allowsalarm thresholds to be set in order to prevent weak bonds or squeeze‐out.The sensor has an automatic calibration feature to aid in establishingaccurate maximum and minimum settings. When used with the LogiCommsystem, defective products are tracked through the machine and ejected ormarked for later ejection.

See Figure 1 for a system overview.

Operational Overview The GD500‐2 system monitors the amount of liquid adhesive on a product bymeasuring the dielectric coefficient of the material passing between thesensor arms. The dielectric measurement is directly related to the amount ofadhesive on the carton or other substrate. The GD500‐2 controller learns thecorrect amount of adhesive during an automated dynamic calibrationprocess, see item 6 in Figure 11. The alarm levels are then set to monitor theupper (MAX) and lower (MIN) deviations from the calibration level.

There are two outputs from the GD500‐2 that connect to the LogiCommsensor inputs:

� Glue

The Glue sensor input provides a signal to LogiComm when glue isdetected.

� Excess

The Excess sensor input provides a signal to LogiComm when toomuch glue is detected (above the MAX limit). Also see item 5 inFigure 11 for the status of the two inputs at different signal levels.

The sensor is also sensitive enough to read the change in dielectricmeasurement due to the carton passing between the sensor arms, see item 7 in Figure 11.



Operational Overview (contd)

The sensitivity is adjusted to eliminate false signals from the carton, seeFigure 13.

If the sensitivity threshold level is set too high, the glue sensor will not sensethe board or the glue and the outputs will not change. If the sensitivitythreshold level is set too low, the sensor will be too sensitive and glueoutputs will change as soon as the edge of the board enters between thesensor arms. The correct sensitivity setting is shown in the following figure:

Dynamic Calibration

Use Dynamic Calibration to remove the factory test state and customize theimage settings.

Dynamic Calibration is a process that teaches the GD500‐2 controller theexpected amount of adhesive by measuring the signal from the programmednumber of products as they pass through the sensor.

Use one of the following options for Dynamic Calibration:

� GD500‐2 controller operator panel

� LogiComm touch‐screen

Calibrate from the GD500‐2 Controller

Follow these steps to calibrate from the GD500‐2 controller operator panel:

1. Press (for about two seconds) until the button LED turns from greento yellow.

The display changes to Dyn Calib., see figure on the left.

2. Run the line normally, applying the desired adhesive pattern.

NOTE: The GD500‐2 controller operator panel shows one bar on thescreen for each product to be learned. As each product passes under thesensor, the bars count down as each product is learned. When theprogrammed number of products has passed under the sensor, thesystem returns to Run mode.



Calibrate from the LogiComm Touch‐screen

Follow these steps to calibrate from the touch‐screen:

1. On the Main Menu screen select the sensor associated with GD500‐2glue input (e.g. B1).

2. Touch the Learn Pattern button on the Sensor Menu screen to open thefollowing pop‐up screen:

NOTE: The calibration process starts once the above pop‐up screenappears. The GD500‐2 controller operator panel display changes to Dyn Calib. and the Dynamic Calibration button LED changes from greento yellow. For more details refer to Calibrate from the GD500‐2 Controllergiven earlier.

4. Touch the Cancel button to exit the Calibration pop‐up screen. TheGD500‐2 will complete the calibration process after learning theprogrammed number of products.



Learn Pattern Setup

The final step in setting up the GD500‐2 system is to configure the twopattern verification sensors in the LogiComm control system.

NOTE: It is recommended to name the two sensors according to theirfunction, for e.g. GD500‐2 Glue and GD500‐2 Excess. You can assignsensor names through the LogiComm touch screen, go to: System Setup > Setup Page 4 > Sensor Names menu.

Glue Sensor Input Set‐up

The Glue sensor input is activated when the measured glue amount exceedsthe programmed minimum threshold. This input is usually monitored usingtemplate gluing. Template adhesive application is a verification algorithm thatcompares the measured pattern to a learned template and alarms anydefects outside of the programmed tolerance limit.

Template Verification for Glue Sensor Input

Follow these steps to setup template verification from the touch‐screen:

1. On the Main Menu screen select the sensor associated with GD500‐2glue input (e.g. B1).

2. Touch the Inspection Parameters button.

3. Set the desired tolerance for the start and stop position of the gluepattern, typically using the All Beads settings.

4. Touch the OK button to exit this screen.



Excess Sensor Input Set‐up

The Excess sensor input is usually best monitored using the maximumsetting on a cumulative bead algorithm. Cumulative bead will identify adefective product any time the input is on for longer than the programmedmaximum limit. The maximum limit should be set to the maximum allowedlength of excess glue that is acceptable for the application. The minimumsetting is not used for this function and should be set to zero.

Maximum Setting for Excess Sensor Input

Follow these steps to set maximum limit for excess sensor input from thetouch‐screen:

1. On the Main Menu screen, select the sensor associated with GD500‐2excess input (for e.g. B2).

2. Touch the Inspection Parameters button, and then touch the CumulativeBead button to enable the settings.

3. Define the measurement position in the Cumulative Bead pop‐up screenusing the Delay and Duration settings.

4. Set the minimum setting to zero and the maximum setting according tothe application.

NOTE: Alternately, the excess glue input can also be monitored usingtemplate verification as described in Glue Sensor Input Setup.
