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.
