7. Determine your Conveyor Segment Pitch. This information is
part of your conveyor manufacture’s specifications. If the
specifications are not available, measure (in millimeters) 10
conveyor segments (plates) and divide the measurement by 10.
8. Press Key 5 until CONVEYOR SEGMENT PITCH appears and
use the Arrow Key to enter the Conveyor Segment Pitch.
9. Determine the number of teeth that contact each conveyor
chain segment. This information is part of your conveyor
manufacture’s specifications. If the specifications are not
available, you must visually count the number of teeth that
contact the segment.
10. Press Key 5 until TEETH/CONVEYOR SEGMENT appears
and use the Arrow Key to enter the number of conveyor drive
sprocket teeth per conveyor chain segment.
11. Close Dip Switch S1-5.
12. Measure the distance in millimeters from the trigger sensor
beam to the centerline of the rejector. If you are using a slat
rejector measure from the beam to the upstream edge of the
slat assembly. Accurate measurement is extremely important
for proper calibration.
13. Press Key 4 until INSPECT TRIG TO C/L REJ appears and use
the Arrow Key to enter the measurement in millimeters.
14. Measure the diameter of the production container (in milli-
meters) at the point where the container intersects the trigger
beam. This is the containers can width at the trigger point.
15. Press Key 5 until CAN WIDTH AT TRIG appears and enter (in
millimeters) the production container’s width at the trigger
point.
16. Measure the diameter of the container (in millimeters) at its
widest point. This is the containers maximum diameter.
17. Press Key 5 until MAXIMUM CAN DIAMETER appears and
enter (in millimeters) the production container’s maximum
diameter.
18. Press Key 5 until MAXIMUM LINE SPEED appears and enter
the line speed (in cpm) for your conveyor. This value assumes
12 mm container spacing for preliminary calculations.
