Typically, the
LOWER LIMIT
value will be set to 1800. The
LIGHT
LEVEL
values of the rejected bottles will be held under the heading
LAST DETECT
. Normal bottles should have Light Level readings
ranging from 2400 to 4200.
1. If the system seems to be falsely rejecting bottles due to the Plugged
Neck detector and the
CURRENT LIGHT LEVEL
values of these
false rejects are going below 1800, then the problem should
not
be
corrected with sensitivity adjustment. Such a condition indicates that
insufficient light is reaching the camera's sensor. If this happens, go to
the
INSPECTION SETUP > ISW > CAMERA
screen and take
corrective measures.
The ISW Color Sort feature uses the same information and the same
adjustment as is used in the Plugged Neck detection.
The Color Sort detects bottles which are extremely dark with respect
to the bottle type being run. For example, when running flint bottles,
the system detects dark amber bottles.
2. If it appears that the system is rejecting bottles which are very light in
appearance but which are still an acceptable color, then raise the
UPPER LIMIT
until it is above the
LIGHT LEVEL
value for the
lightest acceptable bottle.
3. If the false rejects are bottles which are very dark, adjust the
LOWER LIMIT
to a value below the value of the darkest acceptable
bottle. If it is necessary to adjust the
LOWER LIMIT
to a value
below 25, then the image brightness (controlled on the
INSPECTION SETUP > ISW > CAMERA
screen) must be
adjusted first.
For Color Sort to function, the
LOWER LIMIT
adjustment will
generally require a higher setting (more sensitive) than it would if
only Plugged Neck detection were being used.
4. If the Color Sort feature is not desired, then disable the feature by
clicking on the button to the left of Plug/Color so that it is red (off).
5. Save the new settings using the
CONTAINER SETUP > BOTTLE
CHANGEOVER
screen.
