Rejecting No Bottles - Filtec OV-II Maintenance, Troubleshooting And Service Manual

SYMPTOM
The vacuum system has
failed or low vacuum (less
than 127 mm [5 inches
Hg]).
The camera lens aperture
and zoom servo positions
have lost calibration or
are not functioning,
causing an image which is
too bright, too dark, or
has the wrong zoom
setting.
Excessive Rejects on one
inspection.
On the STATUS >
SYSTEM screen, the
DETECT COUNT for one
or more inspection systems
will have a high count.

CHECK
The vacuum warning gauge will
be out of tolerance and/or a red
error message will be displayed
on the monitor.
The monitor display for one or
more of the zones will show up
as all dark, all white, or will have
an unusually small or unusually
large bottle image.
Check optical inspection
windows at the bottom of the
Inspection Head Base plate.
Check the OSW optical windows
inside the tunnel.
Contaminants on diffuser disk or
OSW window.
OSW for fallen bottles.
1. Check for and correct any maintenance-related or bottle handling
problems as discussed earlier in this chapter.
2. On CONTROL > SYSTEM screen, verify that each inspection
subsystem's REJECT STATUS function is ON.
Chapter 2: Troubleshooting Procedures
SOLUTION
Ensure that circuit breaker CB1 is on,
the pressure/vacuum converter is
operational, and that the vacuum
gauge reading is within specification.
Verify the servo controller for that
camera is operating properly.
Recalibrate as required.
Clean the windows.
1. Clean diffuser disk and window.
2. Clear the counters using the
CLEAR ALL CNT function.
3. Release the emergency stop
switch long enough to let 5 to 10
more bottles run through the
Omnivision. If all the bottles are
still rejected, then the problem is
not image related. Check RLD
inspection sensitivity. If no
bottles are rejected (this is what
should happen) allow bottles to
pass through the system.
