Unpacking and Positioning the Pattern Controller
1. Exercise care to prevent equipment damage during unpacking.
2. Inspect the equipment for any damage that may have occurred during
shipping. Report any damage to the Nordson representative.
3. Bolt each mounting bracket (included in the pattern controller ship-with
kit) on either side of the pattern controller firmly.
4. Position the pattern controller close to the production line.
WARNING: Equipment must be properly grounded and fused according to
its rated current consumption (see ID plate). Failure to follow the safety
procedures can result in serious injury.
5. Connect the pattern controller power cord to a properly grounded wall
outlet.
NOTE: This pattern controller can be connected by means of power
cables for 110 V
AC
or 230 V
AC
. If a different power cable needs to be
used, the users must provide it themselves.

Remote Input Plug
The remote input plug provided in the ship-with kit connects to the Remote
Input connector. It is typically used to prevent the pattern controller from
dispensing adhesive until a melter or parent machine is ready, as shown in
Figure 4.
To enable the pattern controller to begin dispensing adhesive:
Connect the 24 V
DC
(Remote Input plug, pin 1) to the remote enable
input (Remote Input plug, pin 7) using an electrically isolated contact.
Refer to the Remote Input pin drawing under I/O Connector Pin Layout.
To bypass (or to set to INACTIVE) the remote enable function, refer to
System Settings 1.

Remote Output Plug
The remote output plug provided in the ship-with kit connects to the Remote
Output connector.
Pin Description
A, B and C These pins can be used as alarm outputs, e.g. for
connection to a lamp column or buzzer.
D, E and F If the STAND BY button is actuated in RUN-mode,
the contact is closed. This contact can, for
example, be connected to the parent machine to
trigger enabling of the production line.
The Remote Input initially sends a signal to the
melter to enable the production line. If the LA 404-2
pattern controller is in STAND-BY-mode, however,
the production line must not start up. Start up of the
production line may only occur when the LA 404-2
pattern controller is in RUN-mode.
G, H, J, K and L These pins are activated according to the program
selected. The wire of the output currently in use is
set to 24 V
DC
. This signaling is independent of
STAND-BY- or RUN-mode. These signals are
normally used to activate the heaters in the case of
applications using several melters.
M Signals to the melters indicating adhesive is now
being applied.
