Product Description
Product name
LA-SO is the abbreviation for "Label Applicator Swing-On". The abbreviation ‘SO’
(swing on) distinguishes this applicator from other application techniques such as
‘blow on’ or ‘tamp on’.
Intended Use
The advantage of the LA-SO is that it can be used to apply labels to the fronts [1C]
of products, which is not possible using classic tamp-on applicators (e.g., LA-TO).
Furthermore, the LA-SO can also apply labels to the sides or tops of products moving
at speeds faster than 20 m/min.
Configurations
The LA-SO is available in both right-handed and left-handed versions. LA-SO and
ALX 92x must be of the same handedness, that is both must be RH or LH versions.
System requirements
Compressed air • Compressed air connection must be available
• Mounting surface for pressure controller: See Installing the pressure reducer 
on page 15
ALX 92x • ALX 92x with standard dispensing edge and firmware version 5.33 or higher.
• Installed applicator interface (optional) with firmware version 1.23 or higher. If the
applicator interface was retrofittet, pay attention that the D-Sub 15 connector for
Avery applicators (top side of the front hood) is available.

LA-SO Product Description

Functionality
The LA-SO is a supplementary module for mounting at an ALX 92x. It takes over la-
bels from the dispensing edge of the ALX 92x and moves them in a curved move-
ment to the product, where it presses the labels on (frontside) or rolles it on (side, top
side).
The advantage of the LA-SO is that it can apply labels to the front side of a product,
which is not possible with classic tamp-on applicators (e.g. LA-TO).
Furthermore, the LA-SO can label products that are moving with more than 20 m/min
on the side or top side.
[1] Designations for the sides of the product. Possible label positions for side labelling (left figure) and
top labelling (right figure).
ASide
BTop
CFront
Initially, the LA-SO is in idle mode and the swivel arm is folded inwards.
As soon as a start signal is received from the product sensor, the ALX 92x prints and
dispenses a label [2B]. The stream of compressed air emitted from the support air
nozzle [2A] presses the label against the pressure plate of the LA-SO [2C]. The label
is held in place there by a vacuum created by the fan on the swivel arm.
[2] Dispensing labels onto the pressure plate.
Once a label has been dispensed, a compressed air valve switches and causes the
swivel arm to move. The swivel movement ends once the time limit set in the ALS 92x
menu elapses. This time limit must be set so that the swivel arm reaches the product
before the reverse movement begins.

General safety notes
• Operating air pressure: 4-6 bar.
• The applicator must not be operated outdoors or in EX-areas.
• The applicator may only be installed and started up by authorized technicians.
• Lay cables and compressed air hoses in a way that nobody can stumble over it.
• Fix pneumatic hoses against lashing.
• Immediately replace defective pneumatic hoses.
• Only authorized technicians who are familiar with the associated hazards are
permitted to repair the applicator.
• Check the applicator regularly for faulty components. Immediately replace any
defective components with OEM parts! This reduces any safety hazards resulting
from the use of low quality parts.
• The on-off valve of the applicator must be set correctly. After switching on the
supply air, the swivel arm of the applicator must move slowly to the home posi-
tion. If the swivel arm moves abruptly, the on-off valve must be checked regard-
ing a defect or a misalignment of the valve, see Setting the on-off valve on
page 19.
• Never modify the design of the applicator (e.g., by installing a higher capacity
pneumatic cylinder). If the applicator is altered without authorization or used in
an unintended manner, all liabilities for damage and any other guarantees from
the manufacturer shall be rendered null and void.
WARNING!
Danger of cuts and crush injuries especially at the following points:
• Between the swivel arm of the applicator and the dispensing edge.
• Between the swivel arm and a conveyor belt, if present.
Never operate the applicator without the protective equipment. See chapter
Connecting an interlocking guard on page 10.
Never remove or disable the safety equipment.
Never touch the applicator while it is moving.
When adjusting the system, make sure that the applicator is not actuated unin-
tentionally.

LA-SO Settings
17
Settings
Settings in parameter menu
The following parameters determine how the ALX 92x
and LA-SO operate. You must set these parameters
before using the unit for the first time:
Dwell time
The required dwell time depends on the following fac-
tors:
• Product face to receive label (front or side)
– Front: Swivel arm must reach the product within
dwell time. Since the angle to be traversed is al-
ways 90°, the required time depends on the
speed of the swivel arm. The speed is set using
the choker valve on the swivel module.
– Side: The dwell time must be long enough to al-
low the swivel arm to reach the product where
the label is rolled on the side. Thus, the re-
quired time depends on the distance to be tra-
versed and the product speed.
• Product speed: The product speed affects the re-
quired dwell time (see above). With slowly moving
products, the swivel arm can move slower. There-
fore, the dwell time is longer than with quickly mov-
ing products.
• Product clearance: For products with a smaller
clearance, the swivel arm must move more quickly
back to the idle position than for products with a
larger clearance.
WARNING!
Pinch and shear hazard, especially at the
following locations:
• Between swivel arm and dispensing
edge.
• Between swivel arm and conveyor
belt, if any.
For this reason pay attention to the follo-
wing when triggering the applicator for test
or setup purposes...
keep a sufficient distance.
don´t touch the applicator.

Recommended starting value for front application:
400 ms (for 5 bar air pressure with choker valve for for-
wards movement turned in by 2.0 mm).
Setting the choker valve
The swivel unit is equipped with two choker valves: one
for forwards and one for reverse movement. The valves
limit the air flow whereby the following applies: the high-
er the flow rate, the faster the swivel arm will move. The
required speed depends on the product speed and the
product separation.
Tools
Small screwdriver (0.6x4 mm)
Setting
Increase flow rate (speed):
Turn the setting screw out.
Reduce the flow rate (speed):
Turn the setting screw in.
Factory setting:
Setting the dwell time
Set the dwell time using APPLICATOR PARA > Dwell time.
Recommended initial setting: 500 ms
Front labelling:
Change the dwell time in steps until the swivel arm
just barely reaches the product.
Side labelling:
Set the dwell time until the pressure roller of the
swivel arm is able to press against the product for a pe-
riod sufficiently long to apply the entire label.

Setting the on-off valve
The on-off valve [20A] is a safety relevant part of the
applicator. It prevents an abrupt backward movement
of the swivel arm, when the compressed air is switched
on.
The on-off valve is factory-set. The setting is fixed with
locking varnish.
If the swivel arm of the LA-SO moves back to the
home position very abruptly, as soon as the com-
pressed air is switched on, the on-off valve is not set
correctly or it is defective.
A faulty setting has to be corrected as described be-
low.
Exchange a defective valve. Set the new valve as
described below (only required, if the valve was not or-
dered at Avery Dennison).
Tools:
• Screwdriver, small (0.6x4 mm)
• Screw locking varnish
Setting:
1. Turn set screw [20B] up to the limit in direction
„slow“.
2. Plug in the supply air hose [20C]. Pull off the out-
hoses [20D].
The arrow at the valve shows the flow direction.
3. Set the supply air pressure to 6 bar.
4. Slowly turn out the set screw, until the supply air
starts streaming through the valve.
5. Turn out set screw ½ turn further.
6. Switch off the supply air. Pull off the supply hose.
7. Lock set screw with locking varnish.
WARNING
High risk of getting fingers or hands crushed
due to abruptly backwards moving swivel
arm.
Set the on-off valve as described below.
Be cautious when switching on the com-
pressed air.
