LA 404-2
Issued 12/06
System Features
Self configuration upon power up
LCD programming/setup menu screen
The operating system software in the pattern controller allows
electronic field software upgrades via the computer’s serial port
Capable of storing up to 100 programs
Can dynamically change program parameters during pattern
controller operation
Monitors fault and warning conditions
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
DC
gun driver
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:
