PRODUCT SET-UP POSITIONING THE PRODUCT DETECTORS There are two fundamental methods to trigger the applicator: the Normal Mode, and the Specific Mode. In the Normal Mode, one product detector triggers both tamps at individual time/ distances from the initial (only) product detection. In the Specific Mode, two product detectors are used to trigger specific tamps. One product detector triggers the swing tamps and the other product detector triggers the straight tamp. The product detectors must be positioned according to the configuration of the applicator. When using the dual tamp for front and side application, or side and rear applicator: A. In the Advanced Menu, dual tamp mode must be set to Yes. B. The first product detector to encounter the product is Product Detector #1. Product Detector #1 must be connected to the Product Detector #1 connector on the applicator. C. In the Advanced Menu, the SWING TAMP FIRST setting must be set so the appropriate tamp will apply the first label to the product. When using a single tamp for front, rear, or side application: A. One product detector only is used and it is always connected to the Product Detector #1 connector on the applicator. B. In the Advanced Menu, the DUAL TAMP MODE must be set to NO and the SWING TAMP FIRST setting must be set for the tamp that will apply the label. Follow the appropriate instructions for a dual tamp applicator (front and side, or side and rear) or for a single tamp applicator (front, or side, or rear). 2 ...

Measure the distance from Product Detector #1 to the fully extended swing tamps. Record the distance "X". See Figure 8. 6.If the conveyor is running at 45 feet per minute, the conveyor is running at approximately 9 inches per second. If the conveyor is running at 15 meters per minute, the conveyor is running at approximately 0.25 meters per second. NOTE: If the conveyor is running at some different speed, determine how far the conveyor travels in one second. 7.Divide the distance "X" by the conveyor speed per second. The resulting number is the approximate LABEL ON PRODUCT POSITION. Use the [UP] and the [DOWN] buttons to set the LABEL ON PRODUCT POSITION to slightly less than the calculated number. 8.

As an option, the applicator can be equipped to either monitor the End of Web, or Web Break, but not both. This detector requires no set‐up and is mounted adjacent to the web path. When the detector detects the absence of the web, the alarm occurs. The single standard alarm light will also blink slowly if the printer power switch is OFF (0) whenever the main power switch is ON (I), and the machine is ONLINE. The single standard alarm light will stop blinking when the printer power switch is turned ON (I) and then the machine is placed 0 FFLIN E and then back ONLINE. The [ESC] button serves as the reset switch for the Low Label, Low Ribbon, End of Web, and Web Break alarms. LOW LABEL DETECTOR The low label detector is a photoelectric sensor which triggers the alarm light when the supply of labels is almost exhausted. Use the following procedure to check the function of the Low Label Detector. 1. Place the machine ONLINE. NOTE: The alarm light will not function with the machine OFFLINE. 2. Push the dancer arm toward the printer and rotate the unwind roll of labels until the slot in the inner unwind disk is directly in front of the low label detector. 3. Remove the outer unwind disk and slide the full roll of labels away from the inner unwind disk. 4. If the low label alarm detector sensitivity is properly set, the alarm light will activate. 5. If the alarm light is functioning, replace the labels on the unwind and go on to the Low Label Alarm Trigger Point. If the alarm light is not functioning properly, go on to the LOW LABEL SENSITIVITY SECTION. 28 ...

Figure 11 Low label Alarm Adjustment 2.Push the dancer arm toward the printer and rotate the unwind roll of labels until the slot in the inner unwind disk is directly in front of the low label detector. Notice the red spot on the label supply. The red spot is generated by the detector and is the alarm trigger point. 3.Use a 9/64 inch hex head wrench to loosen the low label detector's adjustment screws. See Figure 11. Decide how much label supply should remain. When the low label alarm is triggered. Slide the detector to put the red spot at the desired trigger point. Tighten the adjustment screws.

Use the screwdriver to turn the sensitivity adjustment screw clockwise until the orange indicator just goes on. 8. Rotate the unwind disk slightly so that the red spot is directed onto the unwind disk. The detector's green LED must remain ON. Adjust the sensitivity if necessary so that the green LED on the rear of the detector remains ON when the unwind disk or the label roll is in front of the detector. 9. Rotate the unwind disk slightly so that the red spot is directed onto the label roll. Remove the outer unwind disk and move the label roll away from the low label detector.

ADJUSTMENTS UNWIND BRAKE ADJUSTMENT The following procedure should only be performed by a Qualified Service Technician. Place the machine offline before you perform the following procedures or you may be injured by the moving unwind disk or dancer arm. Figure 13 Unwind Brake configuration Figure 13 shows the standard spring and strap arrangement. If the strap is too loose, the brake will not stop the unwind mandrel. If the strap is too tight, the printer's stepper motor must pull against the unwind brake especially near the end of a roll of labels. Use the instructions below to adjust the tension of the strap. The dancer arm and unwind brake are of little use if the label core spins on the unwind hubs. If the label core slips on the unwind hubs, apply several labels to the inside of the label core to decrease the inside diameter of the label core. Apply as many labels to the inside of the label core as needed to provide a snug, nonslip ping fit onto the unwind hubs. 39 ...

1. Hold the dancer arm in the retracted position. 2. Make sure that the strap is correctly wound. See figure 13 3. Use a 5/32 inch hex head wrench to loosen the strap collar set screw. 4. Adjust the position of the collar so that the strap is snug when the dancer arm is completely retracted. Tighten the screw. 5.Use a 1/8 inch hex head wrench to loosen the set screw that holds the spring retainer onto the dancer arm shaft. 6.Position the spring retainer so that the strap is held snug on the dancer arm shaft, but the tension releases when the dancer arm is pulled by the advancing label stock. If the tension is too loose, the unwind will not brake properly and a loop of loose label stock will form. If the. Tension is too tight, the printer's stepper motor will be forced to pull against the unwind brake; this will put undue stress on the printer's stepper motor and may cause web stalls, or print registration errors. 7.Check the adjustment of the unwind brake at the beginning and at the end of a roll of labels, and adjust if necessary. 40 ...

TAMP INTERRUPT SENSOR Normally, the side tamp is not fully extended when the air blast transfers the label onto the product. The Tamp Interrupt Sensor can be used to prevent the tamp pad from colliding with the product when labeling products of different sizes, or when products are presented in various positions relative to the applicator. When the tamp extends and encounters the product before the tamp has fully extended, the Tamp Interrupt Sensor detects the products. When the tamp interrupt sensor detects the product, the air cylinder is switched off to return the tamp and the air blast is initiated to apply the label. Figure 15 Tamp Interrupt Sensor 46 ...
