Suppressing start signals
A start signal can be prematurely triggered by the
shape of the product or reflective surfaces, what can
cause erroneous labelling. In case of a product causing
unwanted additional start signals while the product
passes the dispensing edge, those signals can be
suppressed by setting function LABEL SETUP > Product
length to the product length.
Example [56]:
If the product [D] reaches the product sensor [C], a start
signal is sent and the machine dispenses a label. The
recesses in the product trigger additional start signals;
the product would be labelled several times. With the
product length [A] set in the LABEL SETUP > Product length
function, the machine ignores all start signals until the
product has passed the dispensing edge.
Label position on the product
Prerequisites:
– The label length must be specified.
– The label stop position must be set.
Configuration in dispensing mode:
Use the two right buttons to set the start offset (see
“Online settings” on page 30).
Or use the function menu settings:
Call the LABEL SETUP > Start offset function and set the
start offset.
– The label should be flush with the front edge of the
product:
Enter the distance between the product sensor and
the dispensing edge [57A].
– The label should be stuck at a distance from the
front edge of the product:
Increase the start offset by the distance [58A] to the
product’s front edge.
