3. Installing the Tachometer A tachometer is required to measure conveyor movement for gap tracking Refer to Gap Tracking on page 4 11 for more information Gap tracking is required when there is the possibility that more than one box may be in the scanning zone at the same time You must provide a custom bracket to mount the tachometer securely to your conveyor Connect the tachometer to a driven roller or other driven rotational part of your conveyor using a flexible shaft coupling or a belt and pulley drive as shown in Figure 2 1 FIGURE 2 1 Tachometer Driver by Flexible Shaft Coupling Shaft Coupling Tachometer Housing Note You must use an appropriate flexible shaft coupling or belt and pulley drive to provide mechanical isolation of the tachometer from your conveyor Without such isolation the tachometer is subject to misalignment roller shaft wobble and consequent wear to the tachometer s precision bearings Alternatively a friction wheel can be used to couple the tachometer to the surface of a belted conveyor Friction drives have the potential to slip and cause tracking errors over time but may be suitable for your application A suitable measuring wheel P N 16002070215 with a 12 circumference a white rubber surface and an inside diameter compatible with the standard SICK Auto Ident Inc tachometer and a universal tracking mounting base P N 14005750000 can be purch

Chapter Startup amp Operation From a stop the motor may take as much as 10 seconds to come to its set speed and stabilize If the scanner 18 reset when the motor is already up to speed motor stabilization may take as little as three seconds The laser control software prevents the laser from turning on until the motor speed stabilizes above a minimum speed of 100 s s scans second and will turn the laser off if the motor speed drops below that minimum speed The motor speed must then re stabilize above the minimum speed before the laser will turn on again The laser will not turn on until the motor speed has stabilized If the motor does not stabilize within one minute the software will turn on without turning on the laser During the one minute waiting period the software will display the WAITING FOR STABLE MOTOR SPEED message Table 5 1 shows the minimum acceptable scan motor speeds associated with each of the DSP clock rates described in 009 CLOCK RATES in the Scanner Parameters Reference Guide TABLE 5 1 Minimum Acceptable Scan Speeds DSP Clock Rate MHz Motor Speed scans second 75A 76 78 40 610 32 488 25 380 20 305 Motor speed settings below these thresholds will result in the DSP bar timing being reduced You will then see a startup message similar to the following CIDSP Download Complete No network card detected PREBOOT VX X FLASH ROM BOOT MONITOR VX X CIDSP Non

D o Tilt Tilt 1s the rotation of a barcode about an axis that passes through the barcode perpendicular to its plane As shown in Figure 4 9 the barcode cannot be read by a single laser scan when the tilt becomes so great that the beam does not cut across all of the bars and spaces during one sweep E o E kel o FIGURE 4 9 Varying Degrees of Tilt SS SS Scanning line If your scanner is equipped with optional CIX technology then greater tilt can be handled As long as the scanner beam passes through at least one complete character in the barcode on each scan the scanner can stitch the pieces of code obtained from multiple scans together until a complete decode 18 obtained If your scanner is not equipped with CIX technology then a successful read and decode of a barcode can only be obtained if the scanning beam crosses every bar and space in the barcode in a single sweep If even one bar or space is missed a No Read will result Figure 4 9 shows the barcode on that the right is tilted so far that CIX technology is required to read it Rev F February 2002 CiMAX 75xxA 76xx Scanner Technical Reference Manual 4 7 Chapter Introduction to Scanning Pitch Pitch is the rotation of the barcode about an axis parallel to and in the plane of the bars and spaces as shown in Figure 4 10 The greater the barcode pitch the thinner the bars and spaces will appear
