Installing the SLC1 Series Label Sensor
Figure 2. Allowing the web to glide over the bottom fork with slight
tension lessens the effects of web flutter.
Mount directly and securely to a firm surface using M4 (#8)
hardware (bolts not included). See dimensions for mounting
hole locations. To lessen the effects of web flutter, position
the bottom fork of the sensor slightly above the web’s path
so that the web can glide over the bottom fork with slight
tension.
For the most reliable operation, take steps to eliminate
static electricity near the SLC1 Label Sensor.
Operating the SLC1 Series Label Sensor
The SLC1 Series is self-teaching and needs no programming;
there are no adjustments to set. Simply align the label web
in the slot, between the guides, and allow the labels to run
through the sensor. After the passing of four successive
labels or 250 milliseconds (whichever is greater), the SLC1
learns the characteristics of the labels and adjusts for the
proper sensing threshold and drift compensation.
For best self-programming results, turn power to the sensor
ON or perform a reset after the web has been positioned in
the slot. Align the labels within the web alignment guides on
the side of the sensor slot as completely as possible.
For best repeatability, position the label to cover the entire
sensing area (between the sensor’s web alignment guides,
see Figure 2 on page 2). Some label configurations are
sensed with greater repeatability than others; the sensor
performs best when there is an abrupt change between
labels. For example, labels with sharply defined edges that
are perpendicular to the web direction and have larger gaps
between labels are sensed most easily. Tiny gaps between
labels and labels whose shape tapers at the leading and
trailing edges are more difficult to sense.

If sensing a label with a shape like that shown in Figure 4 on page 3, the best repeatability results if the most
perpendicular edge of the label is aligned fully within the sensing area.
