Note
: The number of LEDs displayed for the clip(s) may vary slightly
as the clip passes through from one time to the next. This is caused by a
slight non-linearity in the electromagnetic field near the receiver coils
and will not cause any problem.
8. Compare the old and new CLP FINE values.
If they are within 50 of each other or the new value is less than the
original value, the auto-calibration set the clip sensitivity too high.
You will have to set clip sensitivity manually.
If the CLP FINE value is less than 500, there may not be enough
range in the clip fine adjustment. Go on to Step 9.
If the CLP FINE value is greater than 500, go to Step 14.
9. Scroll to the CLP CORS display.
10. Decrease the clip coarse sensitivity value shown in the counter by
and press enter.
11. Scroll to the clip fine display and press enter (without changing the
value) to start an auto-calibration.
12. Allow at least two complete revolutions of the conveyor belt, then
press ENTER.
The display shows CLP DONE. The counter shows the clip fine
sensitivity setting.
13. Run the conveyor and watch for false trips.
14. If no false trips occur, the CLP FINE value is set correctly. Do not
proceed with any further steps in this procedure unless additional
false tripping occurs.
If false trips are still occurring, go on to Step 14.
15. Decrease the CLP FINE value by 10 and press ENTER.
16. Run the conveyor and watch for false trips.
If false trips from the clip still occur, continue decreasing the CLP
FINE value by 50 until the largest clip passes without tripping the
detector.
