Infrared Residual Liquid Detection (IR RLD) Excessive False Rejects
There is no visual display for IR RLD. If the IR RLD system is producing
excessive false rejects, proceed as follows:
1. Go to the
INSPECTION SETUP > RLD
screen to display the RLD
parameters.
2. Look at the values for the
IR RLD SENSOR
under the
CURRENT
heading -- they should range from approximately 100 to approxi-
mately 900. The value under the
AVERAGE
heading will normally
be in the range from 200 to 600.
3. If the
CURRENT
or
AVERAGE
values are out of the range, or if the
CURRENT
value tends to occasionally have a value of 1,023 or of 0,
then the problem is not one of over-sensitivity. (You can determine
this by watching the readings while at least 1,000 bottles pass through
the system.) If this is the case, the IR RLD Sensitivity should be
revised to adjust the average to the recommended range.
4. Save the new settings using the
CONTAINER SETUP > BOTTLE
CHANGEOVER
screen
Radio Frequency Residual Liquid Detection (RF RLD) Excessive False Rejects
There is no visual display for RF RLD. If the upstream RF RLD system is
producing excessive false rejects, proceed as follows:
