Warning or Caution
HM
CAUTION: Hot surfaces! Avoid contact with the hot metal surfaces of
guns, hoses, and certain components of the melter. If contact can not
be avoided, wear heat-protective gloves and clothing when working
around heated equipment. Failure to avoid contact with hot metal
surfaces can result in personal injury.
HM
CAUTION: Some Nordson melters are specifically designed to
process polyurethane reactive (PUR) hot melt. Attempting to process
PUR in equipment not specifically designed for this purpose can
damage the equipment and cause premature reaction of the hot melt.
If you are unsure of the equipment’s ability to process PUR, contact
your Nordson representative for assistance.
HM, CA
CAUTION: Before using any cleaning or flushing compound on or in
the equipment, read and comply with the manufacturer’s instructions
and the MSDS supplied with the compound. Some cleaning
compounds can react unpredictably with hot melt or cold adhesive,
resulting in damage to the equipment.
HM
CAUTION: Nordson hot melt equipment is factory tested with
Nordson Type R fluid that contains polyester adipate plasticizer.
Certain hot melt materials can react with Type R fluid and form a solid
gum that can clog the equipment. Before using the equipment,
confirm that the hot melt is compatible with Type R fluid.
Other Safety Precautions
Do not use an open flame to heat hot melt system components.
Check high pressure hoses daily for signs of excessive wear, damage,
or leaks.
Never point a dispensing handgun at yourself or others.
Suspend dispensing handguns by their proper suspension point.

First Aid
If molten hot melt comes in contact with your skin:
1. Do NOT attempt to remove the molten hot melt from your skin.
2. Immediately soak the affected area in clean, cold water until the hot
melt has cooled.
3. Do NOT attempt to remove the solidified hot melt from your skin.
4. In case of severe burns, treat for shock.
5. Seek expert medical attention immediately. Give the MSDS for the hot
melt to the medical personnel providing treatment.
Electrical Safety
WARNING: Risk of electrical shock. Failure to heed a warning could lead
to personal injury and/or damage to the unit or other equipment.
WARNING: Disconnect equipment from the line voltage.

System Overview
The LA 404-2 Pattern Control System generates the signals required to
accurately dispense adhesive on a variable speed production line. The
system monitors the production line position through a pulse encoder. The
pattern controller detects a product traveling down the production line using
a photosensor and then activates the glue guns which dispense the
programmed pattern.

System Description
The pattern controller is a four-channel, four-trigger distance-based device
that is capable of supplying signals to electric and pneumatic guns at line
speed of up to 600 m/min. It has integral drivers that can drive guns like LA
820, LA 844, LA 822 and 24 V
DC
pneumatic guns using hot melt and cold
adhesive.
The pattern controller is programmable with a multi-line menu driven LCD
(liquid crystal display). It has three programming modes Administrator,
Setup and Operator. The Administrator mode is used for an initial setup
when the pattern controller is installed for the first time. Setup mode is used
to create a new program when the product changes. Operator mode
enables the simplest functions to be used in the program selected.
