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. The 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 device 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.

OPTIONS
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
[12] Standard dispensing edge
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.

Printer
– If necessary, you can mount a hot stamp printer (not available from Avery Dennison) onto the holder brackets of the dispensing edge.
– Example of use: Printing consecutive numbers onto labels.
Applicator
If it is not possible to label directly from the dispensing edge, you can fit an applicator to the label dispenser.
Various types of applicators are available that depend on the given requirements.
Simple applicators can be controlled directly via the
PLC signal interface [5G] that is available as standard.

WARNING!
This machine operates using mains voltage!
Touching live electrical parts may expose you to hazardous electrical currents and may lead to burns.
£ Make sure that the device is switched off before you connect the power cable.
£ (ALS 20X)Only operate the device with the mains voltage set on the voltage selector switch.
£ (ALS 20X) Ensure that the unit is set to receive the mains voltage supplied by your electricity provider.
£ (ALS 256) Only operate the device using the system voltage indicated on the nameplate.
£ Only connect the unit to a grounded power socket fitted to authorised standards.
£ The power cable should not be more than
3 m long.
The device is only completely disconnected
from the mains if the power cable is unplugged. Therefore:
£ Make sure the power supply socket is accessible.
£ In case of emergency, switch off the device and disconnect the power cable!

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 [46].
ALS 20X and ALS 256 labellers are preconfigured 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.
The value ‘0’ will cause the label to stop with its front edge directly under the label sensor.
The front edge of the next label to be dispensed should be flush with the 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 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

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 >

Replacing fuses
This section counts only for ALS 20X. The fuses at the ALS 256 cannot be replaced.
WARNING!
The machine operates using mains voltage!
Touching live electrical parts may expose 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.
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.

£ Carry out the cleaning and maintenance work described below.
Removing paper debris
£ Wipe the paper residue from the rollers and edges.
£ Clean the sensor lenses with a soft brush or cloth.
Renewal of the dust filter liner (ALS 256)
CAUTION!
An exhausted filter liner can cause the machine to overheat and to break down.
£ Replace the filter liner regularly, at least in monthly intervals.
In case of overheating the machine, the error message
„5026 MotorProtect CPU“ appears, see “List of error messages” on page 50.
