Dispensing speed
You can set the dispensing speed to a fixed value or
you can configure it to automatically adjust to the speed
of the conveyor belt (speed adaption). The second
option requires you to connect a rotary encoder that
measures and relays the conveyor speed to the
dispenser.
Configuring a fixed value:
£ Use the two left buttons to set the speed in
dispensing mode (online settings) (see “Online
settings” on page 25).
Or use the function menu settings:
£ Call the LABEL SETUP > Dispense speed function and
set the speed you require.
Configuring speed adaption:
£ Turn the function on by setting MACHINE SETUP >
Speed Adaption to ‘Yes’.
£ Set
MACHINE SETUP > Encoder Resol.
and
MACHINE SETUP > Encoder Diameter
as
appropriate for the employed rotary
encoder.
– See the service manual for information on suitable
rotary encoders.
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 [51]:
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.
