Mechanical Installation of the Scanner
At least one product scanner should be installed to detect the leading edge of the product. A single scanner can be
used to start the glue patterns of both channel I and channel II
or the channels can work individually off of separate
scanners.
To install the scanner on a combi glue station (Figure 6-11), follow these steps:
1. Using the two screws included with the scanner, fasten the scanner to the combi station on the mounting
block as shown in Figure 12. This will preset the scanner height and cell-to-gun distance. (The cell-to-gun
distance will be approximately 4.37 inches.)
Note! For machine speeds in excess of 1200 feet per minute, the scanner cannot be mounted to the combi
station. To achieve the 6-inch minimum cell-to-gun distance, the scanner must be mounted to the
brackets as shown in Figure 13.
To install the scanner on a top-down glue station (Figure 6-10), follow these steps:
1. Position the scanner assembly brackets upstream from the glue station.
2. Set the scanner 1.5 to 2.0 inches (38mm to 51mm) above the product.
Note! Scanner must see through an open area on the parent machine with no obstructions.
Note! The distance between the scanner and the glue valve’s nozzle (cell-to-gun distance) cannot exceed
the distance from the leading edge of a product to the leading edge of the next product (repeat
dimension).
Note! The minimum distance allowed between the scanner and the glue valve will be greater at high
parent machine speed. This is due to the response time (delay) of the valves themselves. See
Figure 5 for minimum cell-to-gun distances (a 20 ms delay is pre-calculated for each speed
increment listed in the Table 6-2).
Table 6-2. Cell-to-Gun Distances
Speed Minimum Cell-to-Gun Distance
100 ft/min (30.5 m/min) 1" (25.4 mm)
500 ft/min (152.4 m/min) 2" (51 mm)
1000 ft/min (304.8 m/min) 4" (102 mm)
1500 ft/min (457 m/min) 6" (152 mm)
2000 ft/min (610 m/min) 8" (203 mm)
Electrical Installation of the Scanner
The cable used to connect the scanner(s) to the VC350A control should have a minimum of three conductors (18-22
AWG) and a shield.
To connect the scanner to the control, follow these steps:
1. Insert the scanner cable into the control enclosure through a cord grip located on the bottom panel of
the control.
2. Connect the scanner cable to the five-terminal connector labeled “J1-Scanner1” on the interface board
(Figure 11).
