Performing the Test
For a detailed description of how to perform the test, refer to the
S-Feeder Test Station
job guide, item
no. 00196576-01.
When testing the feeder modules, always perform the individual steps in the following order:
1. Position the feeder module onto the location surface of the
S-Feeder Checking Device
and connect
it.
2. Select the feeder module type in the software.
3. If the tooth is not in the correct position, change the pickup position of the feeder module.
4. Set the step size of the track(s) to be tested to 4 mm.
5. Place the test tape in the track(s) to be tested.
6. Test the feeder module.
7. Wait for the test results and save these if required.
8. Start the automatic tape ejection process.
9. Remove the feeder module from the location surface of the
S-Feeder Checking Device
.

Results display
The overall results of the Test feeder function will be shown in a separate dialog box.
Each tested track is assessed separately. If an error has occurred at a particular track, the cause of this
error will be shown to the right of the icon (cross).
Click on Details to view the detailed test results for an individual track.
Click on the Protocol… button to view the whole test result as a PDF file which can then be saved and/
or printed out.
To make sure that you are able to clearly identify or assign the log file later on, enter the serial number
of the tested feeder in the dialog box.

Precondition
Precondition: the computer, power pack and S-Feeder Checking Device are switched on; the
S-Feeder Test Station software has started.

Detailed Measurements View
The upper part of the displayed graphic shows the position of the individual teeth in the direction of feed-
ing while the lower part shows the individual teeth across the direction of feeding.
The individual teeth of the toothed wheel are marked on the horizontal axis (1).
The horizontal black zero line (2) marks the target position of the individual teeth. In an ideal case, all
measurements would be on this line. The measured positions of the individual teeth are shown as dots.
The diagram shows two rotations of the toothed wheel. The broken black line running vertically (3) marks
the end of the first rotation.
There are two tolerance areas:
The two orange lines (4) mark the limits of the absolute tolerance area. The lines correspond to the or-
ange rectangle in the camera image. These lines have a fixed position.
The two blue lines (5) mark the limits of the repeat accuracy. These lines can be shifted according to the
average value of all measurements. The repeat accuracy is primarily affected by the following three fac-
tors:
▪ Gear play
▪ Roundness of the toothed wheel
▪ Deformation of the teeth
The green dots show the measuring results which are inside the two tolerance areas.
The red dots show measuring values which are outside at least one of the tolerance areas.
Red squares show positions at which measurement failed.
In the diagram shown, all measurements are within the two tolerance areas.
The measurements are generally shifted slightly upwards. On the feeder, this corresponds to a shift in
pickup position forwards, in the direction of transport.
The measurements show a sinusoidal character in both rotations i.e. the toothed wheel is not perfectly
round.
The measurements from the first and second rotation largely correlate, indicating that the gear play is
minor.
NOTICE
Type and source of danger
The following examples only show the top half of the diagram. The description applies equally
to the bottom half of the diagram.

5.2.3.1
5.2.3.1 Measurements Outside the Tolerance
Measurements Outside the Tolerance
Some of the measurements are outside the absolute tolerance area. These values can be recognized
in the image during the measurement: the cross is outside the orange rectangle and is shown in red.
► Readjust the pickup position of the track.
The measurements spread between the first and second rotation. This indicates a more major gear play.
This feeder only just keeps to the repeat accuracy.
5.2.3.2
5.2.3.2 Repeat Accuracy Insufficient
Repeat Accuracy Insufficient
Some of the measurements in the diagram shown violate both the limits for the repeat accuracy and
those of the absolute tolerance area. In this case, both the play and the pickup position need to be reset
for the toothed wheel.

5.2.3.3 Unable to Measure At Least 3 Points
Unable to Measure At Least 3 Points
If the software is unable to determine a position three times during measurements, this will be acknowl-
edged with the corresponding message.
