Introduction
hank you for purchasing the Little David™ model LX600 series
Apply Only labeler. The LX600 series apply only labelers are
designed to be versatile enough to suit a variety of carton labeling
requirements with one standard unit. All employees who will be
required to operate the labeler should read this manual to ensure proper set-
up, operating safety and a long machine life. After reading this manual you
will know how to perform the following functions,
How to position the labeler to achieve maximum performance.
How to thread the labeler and adjust the sensors to apply labels in the
most efficient manner.
How to use the controller interface.
Troubleshooting and replacing of worn or defective parts.
Throughout this manual there are several illustrations designed to help
you perform the variety of tasks described. These illustrations all depict the
right-hand version of the machine. You can tell a right hand and left hand
machine apart by facing the machine. The side with the plate holding all of
the rollers is the hand version of the machine. The hand designation of your
individual machine does not affect any of the procedures or maintenance
operations described below only that your left hand machine appears as a
mirrored image of the machine depicted in the illustrations.

Operating Safety
Observe the warnings and cautions
below when using the Little David Label
Application Systems. Within this manual, a warning
indicates that the potential for bodily injury exists, and a
caution indicates when the machine may suffer damage.
Instruction: Requirement for System Operation
Socket-outlet shall be installed near the equipment and shall
be easily accessible.
Fuses marked MDA 5A are of type: 250V, 5 Amp, Slow Blow.
Fuses marked MDA 10A are of type: 250V, 10 Amp, Slow Blow.
Warning: Potential Bodily Injury
Always turn off the electrical power before clearing jams, and before
performing maintenance. Use Proper Lock Out / Tag Out
Procedures. Never operate unit without guards in place.
Avoid liquid or excessive moisture when using the system. Do not
operate the system with wet hands, nor in a very humid environment.
Do not spill liquid on the system.
Do not touch moving parts. Turning hubs can bruise or scrape,
rapidly moving label stock can cut like a knife.
If a problem arises that is not covered in this manual, do not attempt
to repair the system yourself, instead, call your nearest service office for
immediate and correct care of the equipment. Trained personnel
should perform all adjustments and service.

Installation and Threading
lways check for any signs that the machine may have been damaged
before fully removing it from the shipping skid.
Section 1: Placing the Machine
The labeler comes fully assembled and already on the mounting
stand. The Plant Manager at your facility might have already
determined a pre-arranged location for the labeler. If no pre-
arranged location exists following the steps below will help
determine the ideal spot.
Step One: Carefully remove all of the items in the shipping box
and skid. There are three lag bolts fastening the labeler to the base of the skid.
While the machine is fully assembled, certain options such as software or
spare parts kits may be packaged separately.



Step Two: Take care removing the machine from the
skid as it weighs approximately 190 pounds depending on
configuration and options.
Step Three: You will need to move and orient the label machine
along your production line in a position relative to your label and product.
A. Positioning the machine for top application or side application
utilizes two locking bolts located on the top of the machine as
shown.
LOCKING
BOLT

B. Alternatively or additionally, you may want to turn the machine
vertically. This is done with the handle found behind the machine.
Note: If the machine is to be inverted (sometimes called bottom
labeling) the handle should be completely removed to move the
machine upside-down. This will expose a new hole that can be
used for the lock handle so that the position is maintained.
C. Vertical height is changed with the handle on the top of the
machine.
Step Four: Once the labeler has been rotated to the
desired position, you will want to load the labels. Loosen the outer clamp with
the handle and remove it, then load you labels as shown and replace the outer
guide. Prior to locking the outer guide in place, leave a little clearance between
the outer guide and the roll of labels; Do Not press the outer guide tightly
against the label roll as it will stop the label roll from unwinding normally and
stall the label feed. (Note: Side Frame Plate and cylinder are removed to
show detail.)

Refer to Section 2: Threading the Label Stock.

Step Three: Take the Label Liner / Web back under the
peel edge. Make sure that the liner threading path does not go
over the Blow Tube when you take the label liner/ web back
under the peel edge blade. Next release the knurled friction roller
with the black knob. Thread the web over the drive roller and
under the friction roller and attach it to the rewind spindle via the
clip.
(Note: Side Frame Plate and cylinder are removed to show
detail.)

The labeler is now threaded and ready to be plugged in and
turned on. You can use the JOG selection on the PanelView
Touch Screen of the control box to advance one label onto the
applicator. If the label comes out too far or not far enough, make
a manual adjustment to the gap sensor position along the slotted
bracket. This will be necessary to achieve the appropriate label
position on the peel edge blade.

Theory of Operation
Apply Only Labeling
Straight Tamp (Touch and Go Linear Applicator) or
Swing Arm Applicator.
The LX600 Apply Only Labeling system is configured in either a
Straight Tamp (Linear Actuator) with a “Touch and Go” Sensor
or with a Rotary Actuator that would provide for a “Swing Arm”
type Label Application for various label application scenarios.
In Straight Tamp (Touch and Go Applications), the labeler
operates when it gets a signal from the product sensor. The
motor turns on and the label is presented out to the applicator
pad and held in place by a vacuum pad that has been designed for
the label size being applied to the box. While being dispends out
to the vacuum pad, a blow tube is turned on to blow a stream or
air to orient the label out to the pad. The fiber optic Label Gap
Sensor determines the end of the label and the PLC program
turns off the blow tube and engages the vacuum solenoid and
stops the motor from turning. At this point the Product Delay
timer times out to the setting as entered by the operator. Once
the Product Delay has time out, the PLC engages the Tamp
Cylinder Apply Solenoid valve to extend and tamp the label on to
the box. A sensor on the pad (Touch and Go Sensor) sees the
target; it sends a signal back to the PLC to turn on the Cylinder
Retract Solenoid valve to return the cylinder to the home position
where a Reed Switch senses the home Position which signals the
PLC that it can accept another label should the product detection
photocell detect another box.
In the Swing Arm Applicator, a timer replaces the Reed switch
and the home sensor provides that signal for proper sequencing
as described above.

Note: The Gap Senor Sensitivity and label position is preset
at the factory. However if no labels are provided, a suitable
labels is used for testing and run off. Label placement and
gap sensor fine tuning may be required at installation and or
label changes.
Sensor Operation: The fiber optic Gap Sensor emits light from
the control module through fiber optic tubes to the gap sensor
assembly. A transitions occurs between the amount of light that is
received through the backing paper (liner) and then through the
label on the liner. (Note: A red “SPOT Light” is emitted to show
the senor target location on the label.) LED indicators on the
control module will illuminate when this is transition occurs.
