The next label to be dispensed waits in the label stop
position. Here it is useful if the label protrudes over the
dispensing edge a little [54].
ALS 20x/ALS 256 labellers are pre-configured
for use with the supplied label sensor. If this
sensor is employed, the label stop position
setting will only require minimal correction.
Correcting the default setting:
Call the LABEL SETUP > Lab. stop offset function.
Increase the value to increase the overhang or
lower the value to reduce the overhang.
[55] Special settings for the label stop position.
b) 19 mm = Distance [54B] between label sensor and dispensing edge (with
fixed L-shape dispensing edge).
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 30).
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.
