Relieving Hydraulic Pressure
1. Prior to maintenance and repair work it is therefore essential to ensure
that all liquid adhesive application system components are
depressurized as follows:
S Release input pressure in front of pump by shutting off customer
compressed air supply.
S Release any remaining system pressure behind the pumps by
manually operating the application heads.
2. Secure pneumatically- and hydraulically-operated equipment against
uncontrolled movement.
3. Switch off system electrically.
Before You Begin
WARNING: Some voltage is still present in the control cabinet even after
equipment has been turned off at the main switch. Complete the following
steps prior to maintenance or repair:
1. Disconnect external power supply.
2. Lock out external power supply.
3. Check no voltage is present.
4. Ground and short.
5. Cover nearby live sections.
If liquid adhesive application system is left idle for extended periods (e.g.
overnight or long breaks) Nordson recommends applying petroleum jelly to
the application head nozzles to prevent them from drying out and becoming
blocked as a result.
Make sure that only genuine Nordson parts are used.

Cleaning
NOTE: Always refer to the liquid adhesive manufacturer’s Material Safety
Data Sheet or material information sheet before working with any cleaning
fluids.
WARNING: Never clean any aluminium part or flush any system using
halogenated hydrocarbon fluids. Examples of common halogenated
hydrocarbons are: dichloromethylene, 1,1,1-trichloroethylene and
perchlorethylene. Halogenated hydrocarbons may react violently with
aluminium parts.
Make sure that the following cleaning guidelines are observed:
S Never use an open flame to clean the system or its components.
S Check that (warm) water can be used to clean the liquid adhesive
system components, possibly with the addition of household washing-up
liquid. If this is not possible, use only the cleaning fluid stated in the
liquid adhesive manufacturer’s information. If the manufacturer
recommends heating the cleaner, note the flash point.
S Ensure sufficient room ventilation to draw off vapors.
WARNING: Fire, open flames and smoking are prohibited when cleaning
fluids are used. Observe all explosion prevention regulations. Cleaning
fluids may only be heated using temperature controlled and
explosion-protected heaters.
S Disposal must be according to the waste key in the DIN Safety Data
Sheet. Liquid adhesives or residue, solvent or separating agents must
not be released into open waterways. In the case of a leak or spillage,
contain liquid and if necessary use an absorbant material e.g. sawdust
to soak it up; then proceed according to the relevant waste disposal
regulations.
S If the liquid adhesive application system is to be idle for an extended
period, the entire system should be flushed and outlets sealed with
petroleum jelly. Warm water is usually used to flush application systems
with which water-based liquid adhesives are processed.
S If the liquid adhesive manufacturer specially recommends a flushing
agent, the manufacturer’s safety and disposal details must be followed.

Liquid Adhesives
As there is a wide variety of liquid adhesives available with different
compositions and characteristics, it is impossible here to give an exhaustive
list of safety notes reflecting the typical characteristics of liquid adhesives.
The use of liquid adhesives in Nordson’s liquid adhesive application
systems therefore requires reference to the liquid adhesive manufacturer’s
documents beforehand.
Information relating to safety aspects e.g. concerning solvent content,
hazards and countermeasures in the event of liquid adhesive coming into
contact with skin or mucous membranes are contained in the technical data
sheets and the DIN Safety Data Sheets from the manufacturer.
Make sure that the following guidelines are observed:
S Always refer to the manufacturer’s Material Safety Data Sheet or
material information before working with any liquid adhesives.
S It may be necessary to refer to the manufacturer’s notes on the use of
materials from a third party. These may be required for processing a
liquid adhesive, but hazards arising from their use are not necessarily
mentioned by the manufacturer of the liquid adhesive.
S Liquid adhesives may still give off vapors when they are processed
correctly. The smell produced can cause some annoyance. This is
especially true where liquid adhesives are used that contain solvent,
thus requiring the use of breathing equipment e.g. a filter.
S If the prescribed processing conditions are not followed, harmful
decomposition products may develop. Therefore, the vapors must be
removed.
S Wash hands well before breaks and when work is finished.
S If liquid adhesive comes into contact with eyes or mucous membranes,
rinse well with water—especially the eyes. Change damp clothes, and
seek medical advice if it is swallowed.
S Disposal must be according to the waste key in the DIN Safety Data
Sheet. Liquid adhesives or residue, solvent or separating agents must
not be released into open waterways. In the case of a leak or spillage,
contain liquid and if necessary use an absorbant material e.g. sawdust
to soak it up; then proceed according to the relevant waste disposal
regulations.
S If solvents or separating agents are used to process a liquid adhesive,
follow the safety and disposal information from the manufacturer.

Operation
Startup
1. Check the glue level in the tank or drum.
2. Set the air pressure for the pump or the tank to the required glue
pressure.
3. Position the guns on the cross bar and clamp into position.
4. Set the height of each gun so that the product can pass under the
nozzle (or guide or tip sealer when used).
NOTE: The guns can be used with the nozzle tip up to 6 – 10 mm
(0.2 – 0.4 in.) away from the surface to be glued. Depending on the
surface of the product, it may be necessary to alter the ON and OFF
compensation values to maintain the accuracy of the glue bead position
as the nozzle gets further away from the product.
NOTE: In general, the faster the speed, the closer the nozzle needs to
be to the surface. For best performance, make sure that the gun nozzle
is as close to the product as possible.
5. Run some product through the machine to make sure that it runs
through without snagging. Adjust the height of the gun(s) if necessary.
6. Set the controller to give the required glue line dimensions. Refer to the
controller product manual.
NOTE: For multi-gun applications where the size of the glue spot is
critical, it may be necessary to adjust the gun opening (the gap between
the plunger and the armature) to obtain the same size spots from all the
guns.
7. Set the gap between the plunger and the armature.
NOTE: If using the LA 822M, LA 822MB, or LA 822MEK gun, loosen
the adjusting locking set screw on the front of the gun.
a. While the gun is energized and glue is flowing, turn the armature nut
clockwise until the glue flow becomes a slow drip.
CAUTION: Be careful not to over-tighten or the ball plunger will be
damaged.
b. After the glue flow stops, rotate the nut counterclockwise one-third of
a turn (2 flats of the hex nut).
c. De-energize the gun.
d. Test the adjustment.
NOTE: If using the LA 822 gun, lock the set screw position.

(contd)
8. Prime the guns for approximately three minutes or long enough to fill
approximately one cup.
9. Remove the gun and hook assembly from each bracket, leaving the
clamp in place as the reference point. Purge each gun in turn for
approximately 20 seconds.
10. Wipe the face of the gun clean with a wet cloth, then purge each gun
again for approximately 20 seconds. When the adhesive stream is
jetting uninterrupted from the end of the nozzle, the gun is fully primed.
NOTE: It is important that no air remains in the glue supply lines.
For Carton Folder/Gluers
1. Refit each gun, making sure that they are replaced in the same position.
2. Inch the cartons through; examine the start/stop positions of each glue
bead and adjust the controller if necessary. Adjust the position of the
guns on the cross bar if required.
3. When using a Glue Regulator unit, set the Standoff to adjust the glue
pressure to give the correct volume of adhesive at the lowest speed.
4. While running the machine at its full running speed, use the Slope to
adjust the pressure to achieve the required volume of adhesive.
For Folding or Mailing Machines
1. Refit each gun and remove the fold plates.
2. Run sheets through, one at a time, and examine each glue bead. Reset
the controller if necessary. Adjust the glue pressure to achieve desired
glue bead width.
3. Replace the fold plates and run 10 sheets through. Check glue beads
for final spread. Adjust pressure if necessary.

TS 422 Tip Sealer
Installation
The TS 422 tip sealer can be mounted on the LA 822 gun to seal/unseal the
gun nozzles. The tip sealer is an air piston, spring return mechanism with
an attached sealing pad. When pressurized air is applied to the piston, the
sealing pad slides away from the nozzle. When pressurized air is removed,
the spring pushes the pad back to cover the nozzle.
The supply of pressurized air to the tip sealer is governed by a solenoid air
valve, that is connected to the TSC 522 tip sealer control unit. The control
unit permits activation of the tip sealer either manually or automatically.
Refer to TSC 522 Tip Sealer Control Unit, given later in this section.

Replacing the Tip Sealer Slide
The tip sealer slide is removable. It is held in position with an engagement
pin that snaps into the piston.

Options
Shutting Off Individual Tip Sealers
Only the working guns should have exposed nozzles while in use. When
several guns are mounted on a machine, and only one or two are used on a
particular job, keep the tip sealers on the unused guns in the closed
position. Air shutoff valves are provided for this purpose. If a particular tip
sealer is shut off, the tip sealer sliding pad remains in the closed position.
Make sure that when a tip sealer air supply is turned OFF, this same gun is
not actuated by the glue pattern controller. Turn OFF both the tip sealer and
gun actuation. Turning the air supply ON returns the tip sealer to the
operating mode.
Mounting and Adjustment
1. Use the two Allen head cap screws (10 X 32 X ½ in.) supplied with the
tip sealer to mount the tip sealer to the gun.
CAUTION: Risk of equipment damage. Do not use longer or shorter
screws. Different size screws may damage the gun.
2. Verify that when the slide is in the sealing position, the sealing pad is
pressing lightly on the nozzle. Place a thin piece of paper between the
nozzle and the pad. Slide the pad to the sealing position, keeping the
paper between the pad and the nozzle, and pull on the paper. It should
not slide out easily. If it does, perform one or all of the following until the
paper is tight between the pad and the nozzle.
a. Make sure that the sealing pad is not dirty, torn, or worn out.
Remove the retaining plate and clean with water or replace as
needed.
b. Raise the mounting position of the tip sealer on the gun to the
maximum allowed to increase the pressure between the pad and the
nozzle.
c. Readjust the engagement pin to increase the upward tension on the
slide.
NOTE: If the engagement pin is readjusted, use a thread locking
compound (Loctite-blue) to prevent free turning of the engagement pin
relative to the slide.
3. Make sure that the piston and O-ring are in good condition and well
lubricated. Use light grease as needed.

TSC 522 Tip Sealer Control Unit
The TSC 522 Tip Sealer Control unit is an electronic device that controls the
activation of the TS 422 tip sealer. Refer to TS 422 Tip Sealer, given earlier
in this section. It has the ability to control this activation manually or
automatically.
The type of glue pattern control unit used determines whether each glue
gun can be activated individually or if several guns are activated together.
The TCU and PDC controllers allow activation of a group of guns connected
to the same channel. The APC controller allows activation of each gun
individually.

Automatic Operation
The automatic operation of the tip sealer is activated by the trigger photo
sensor. When products traveling on the machine pass the trigger photo
sensor they should activate the sensor. An active sensor is signaled by a
blinking red LED on the rear of the sensor. The first trigger of the photo
sensor that is detected by the tip seal control logic activates the sliding pad
of the sealing unit. The sliding pad retracts from the glue gun nozzle,
allowing glue to flow.
NOTE: Earlier activation is possible. Normally the unit is connected to the
photo sensor that starts the glue cycle. If it is necessary to retract the
sealing pad earlier, a secondary photo sensor can be mounted upstream,
which—when connected to the TSC 522—causes actuation of the tip sealer
when triggered. Consult the factory if such an arrangement is desired.
Continuous product flow sensed by the trigger photo sensor causes the tip
sealer to remain retracted/open.
When products stop flowing through the machine, the trigger photo sensor
stops signaling the control logic. After five seconds of inactivity, the control
logic causes the sliding pad to move forward toward the nozzle and seals it.

Manual Operation
The remote key pad allows for remote manual activation of the tip sealer
and of the glue gun. This is required for purging the guns or for checking
their proper operation.
S TIP SEALER Key
- Press the key marked TIP SEALER one time to retract the sliding
pad and expose the nozzle.
-
Press it a second time to make the sliding pad move forward and
seal the nozzle.
S Numbered PURGE Keys
- Press one of the numbered purge key switches (1A, 2A, etc.) to
activate the tip sealer and associated glue gun(s).
-
Press it a second time to release the purge key switch to de-activate
the tip sealer and associated glue gun(s).
Example:
S Press the 1A key to retract the tip sealer and activate the gun or
group of guns associated with channel 1A. The glue output is
slightly delayed to allow the sliding pad to clear the nozzle
before the glue exits.
S Press the 1A key again to release it and immediately de-activate
the gun. This stops the flow of glue and allows the tip sealer
sliding pad to slide back into the nozzle sealing position.

Mounting and Connections
Mount the TSC 522 control unit close to the glue pattern controller to keep
the connecting cables short and put the unit in easy reach of the operator.
See FigureA-2.
1. Mount the air manifold, air valve, and air filter regulator close to the glue
pattern controller, but out of the way of the operator.
2. Using the magnetic mount, mount the key pad to a steel surface in an
area convenient for the operator’s reach.
3. Connect the trigger photo sensor—which is normally connected to the
glue pattern control unit—to the tip sealer control unit.
NOTE: Earlier activation is possible. Normally the unit is connected to
the photo sensor that starts the glue cycle. If it is necessary to retract
the sealing pad earlier, a secondary photo sensor can be mounted
upstream. Consult the factory if such an arrangement is desired.
4. Connect the cable exiting the tip sealer control unit to the trigger photo
sensor socket in the glue pattern controller. This is where the trigger
photo sensor is normally connected.
5. Connect the solenoid air valve to the cable exiting the tip sealer control
unit.
6. Connect the air supply (80 psi) to the air regulator and set the pressure
to 80 psi.
7. Connect the 1/8 in. diameter air tubing to the tip sealer.
