Configure the Diameter Missing Lid Function
The Diameter Missing Lid function utilizes the Inspection Trigger
Beam to determine if a lid is present, therefore you must align the
Inspection Trigger Beam before you configure the Diameter
Missing Lid function. Refer to
Aligning the Inspection Trigger for
instructions on aligning the Inspection Trigger Height.
1. If your FT-70 is not in the Calibrate Mode, Press Key 5 until you
reach SYSTEM DISPLAY and then press the Arrow Key to
enter the Calibrate Mode.
2. Open dip switch S1-5.
3. Press Key 5 until DIA MISSING LID appears and use the
Arrow Key to select PRESENT.
4. Close dip switch S1-5.
5. Press Key 2 until DIA MISSING LID STATUS appears and then
press the Arrow Key to activate the function.
6. Press Key 2 until DIA MISSING LID WIDTH appears.
7. Start the conveyor and run it normal production speed.
8. Place a properly filled and sealed production container on the
conveyor far enough upstream from the FT-70 so that the can
does not slip on the conveyor as it passes through the FT-70.
9. Record the Samples/Interval value that appears in the DIA
MISSING LID WIDTH display.
10. Repeat the previous two steps four more times and then
average the results to get the Average Good Container
Samples/Interval (GS).
11. Repeat the previous three steps using a production container
that is missing a lid. Averaging the unsealed containers will
give you the Average Bad Container Samples/Interval (BS).
12. Use the following equation to determine the Minimum
Diameter Missing Lid value (MD):
