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.

Guns dispense a maximum of four beads. Possible bead types:
normal, continuous, autospot, dot, random bead and random dot.
Four channels with up to two gun capacity per channel
Each channel has a corresponding driver capable of driving two
guns simultaneously
Automatically converts glue line patterns to other bead types
Digital display of machine speed, work rate, and total count
Programmable gun compensation
Signals the active channel for the selected program at the remote
output.
Pressure run-up
Remote gun purge
Encoder scaling
Signals a drop below the minimum speed at the remote output.
Integrated tip sealer control
32 V

Software Upgrade
The pattern controller’s software can be upgraded, and the user programs
can be saved or restored in the field by using the Nordson Configuration
Manager (NCM). The NCM is a Windows -based application that allows the
pattern controller to communicate with a personal computer (PC). The
communication is enabled by a serial cable that is connected to the COM
port (selected during the software installation routine) and the serial port
connection (COM port) located on your pattern controller’s rear panel.
The NCM can be obtained from:
