2.1 OVERVIEW
2.1.4 Mode of operation
In labelling mode, the strip is first pulled from the label
roll around the dancer arm [8A], which consistently
maintains even tension in the label strip. The feed roller
[8D] behind the dispensing edge [8C] draws the strip
across the dispensing plate. The label is unfixed from
the backing paper on the dispensing plate and is
pressed onto the product by the pressure roller [8B].
The feed roller drives the label strip forwards the length
of one label and stops until the next product arrives at
the dispensing plate. The strip feed is started by the
product sensor mounted on the conveyor belt. T he stop
control provided by the label sensor on the dispensing
edge ensures the feed is halted as soon as a gap is detected between two labels.
The spent backing paper runs from the dispensing
edge around the drive roller [8D] to the rewinder [8E].
The dancer arm regulates the rewinding speed.

The entire operation of the label dispenser is controlled
and monitored electronically. If errors occur, the d evice
controls output an appropriate notification for the operator. If necessary, the labelling operating mode is halted automatically. An electronic signal is output at the
same time. The signal can be fed to an external controller and evaluated.

External control panel
– An external control panel can be connected in
addition to the integrated control panel.
– An external control panel is useful if the standard
control panel is difficult to access due to the position
in which the unit is installed.
Fixed dispensing edge
– The dispensing edge has a fixed connection to the
brackets.
– To adjust the vertical position, lift/lower the entire
device.
– The slope angle can be adjusted by rotating the
brackets (see the service manual for further details).

[11] External control panel
Swivelling dispensing edge
– The position of the dispensing edge can be adjusted
vertically.
– The device need not be moved to adjust the position
of the dispensing edge; the device’s mounting need
not be dismantled.
Spring-loaded dispensing edge
– The dispensing edge is pivoted. A torsion spring in
the dispensing head presses the dispensing edge
downwards and onto the surface of the product.
– Allows compensation for height differences
between the products or on the product surface.

before turning on the unit [30].
The minimum required sensors:
– Label sensor (installation location: dispensing edge)
– Product sensor (installation location: conveyor belt)
Additional optional sensors:
– Rotary encoder (required for speed adaption)
– External outer diameter checking sensor (provides
advance warning of the end of a label roll)
– Alternative label sensor; for example, capacitive
sensor, used to detect transparent labels.
You can find further information regarding
suitable sensor types, pin assignments, and so
on in the service manual.

– The product sensor must be connected.
– The sensors must be configured correctly
(PNP/NPN).
Dispensing without a product sensor
It is also possible to trigger the dispensing process
without a product sensor:

dispensing edge a little [46].
ALS20X and ALS 256 labellers are preconfigured for use with the supplied label

4.2 CONFIGURATION AND MONITORING
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 22).
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.

Missing labels
A label missing from the label roll does not normally
affect the dispensing operation, because the label feed
continues until a label’s edge passes under the label
sensor.
Nonetheless, it can be important that missing labels are
reported. By configuring the function LABEL SETUP >
Miss. label tol., you can specify whether an error message
is triggered after one or several missing labels.
Material end

5.1 MAINTENANCE AND CLEANING
5.1.1 Replacing fuses
This section counts only for ALS20X. The fuses at the ALS256 cannot be replaced.
WARNING!
The machine operates using mains voltage!
Touching live electrical parts may exp os e
you to hazardous electrical currents and
may lead to burns.
£ Make sure that the machine is switched
off and the power cable is unplugged
before removing the fuse insert.
CAUTION!
Risk of fire, if a wrong fuse type is inserted.
£ Only replace fuses with the type and
rating specified in this manual.
256
GB
Tool: Screwdriver
£ Turn off the unit. Unplug the power cable.
£ Rotate the fuse holder a few degrees anticlockwise.
– The fuse holder pops up.
£ Take the fuse out of the fuse holder.
£ Replace defective fuse.
£ Replace the fuse holder and rotate it clockwise,
while applying light pressure, until the slot is
vertically positioned.
Required fuse type:
– T5AH 250V
The F1 and F2 fuses protect the primary side of
the transformer. At any given time, only one of
the two fuses is active. Which fuse is active
depends on the switch setting of the voltage
selector switch.
