– Troubleshooting for Negative Measuring Results
If the measuring result is negative, check the following points:
▪ A precondition for the automatic test run is a valid calibration of the S-Feeder Test Station.
If necessary, calibrate the S-Feeder Test Station. See the S-FTS manual.
▪ When using 2x8 mm and 3x8 mm feeders, the test station must recognize the feeder fiducials. If this is not possible, an
error message will be shown.
If necessary, check the fiducial on the feeder with the camera (F8 key)
Check whether the feeder is positioned level on the test station.
▪ Check the spaces between the teeth for components or dirt. Manually adjust the pickup position on the feeder to 2 mm,
so that you can see the spaces between the teeth in the live image. Click on the Full rotation (F3) button to rotate the
toothed wheel. Inspect the spaces between the teeth during this rotation.
Use the magnetic pin to remove any components or contaminants. Use the Single step (F5) function to help you.
▪ Clean the feeder.
▪ Make sure that the test tape is run correctly in the tape duct and that it engages properly in the toothed wheel.
▪ If the measuring result is still negative after a second test run, the feeder will need to be repaired.

– Test with feeder feducial (for 2x8mm S Feeder only)
At some 2x8mm feeder the feeder feducial might be dam-
aged so that it cannot get recognized anymore. In this case
the measurement can be deactivated in order to measure
the feeder anyway.

NOTICE
Position of sprocket wheel
The absolute position of the sprocket wheel will then be measured against the feeder adapter. This might cause
an additional offset (up to 100µm in transport direction and up to 200µm across transport direction), so that the
measurement can exceed the tolerance corner (see chapter 5.2.3.1 "measurement result out of tolerance). Some
of dots are then outside the orange lines.
The feeder however might still be suitable to use (e.g. for chips >= 0805), as long as the repeatability is still good
(measurements are within the blue tolerance lines).
