Installation This section provides pattern controller positioning information and gundriver installation procedure.

Unpacking and Positioning the Pattern Controller 1. Exercise care to prevent equipment damage during unpacking.

2. Inspect for any damage that may have occurred during shipping. Reportany damage to the Nordson representative.

3. Position the pattern controller close to the production line.

Gun Driver Card The pattern controller has the capacity to hold four gun driver cards (drivercard). The type of driver cards used are:

� 4 channel voltage mode driver cards

� 2 channel current mode driver cards

Installing the Driver Card Follow these steps to install a gun driver:

WARNING: Make sure that the pattern controller is not plugged to a linevoltage while installing the driver card.

1. Detach the four screws that hold the driver card in place.

2. Remove the old driver card.



Installing the Driver Card (contd)

3. Slide in the new driver card. Make sure that the driver card slidessecurely along the tracks.

NOTE: The driver card will plug into the edge connector on the backplane board.

6644039A

Figure 6 Location of gun driver cards on the rear panel

4. After the driver card is securely held in position, re-attach the fourscrews.

5. Connect the guns to the driver board on the rear panel.

6. Plug the system power cable into the pattern controller, and connect thepower plug to a power source.



Remote Junction Box The remote junction box is used to reduce the number of cables required forguns and triggers that are mounted remotely from the pattern controller. Asingle gun cable that carries four individual gun signals can run from a4-channel voltage mode driver to the remote junction box. In addition, asingle trigger cable that carries four individual trigger signals can run fromthe pattern controller to the remote junction box.

The remote junction box can be set up with internal jumpers for thefollowing configurations:

� 4 trigger/4 gun

� 2 trigger/6 gun

Remote Junction Box (contd)

The remote junction box can be connected to a 4-channel voltage modedriver. Inside the remote junction box there are configuration switches(SW3, SW4, SW5, SW6) that select what channels are to be purged from itsremote purge input (for location see Figure 7). All positions of the switchshould be closed to purge the indicated engine’s output.

The remote junction box has the flexibility of assigning any of the fourtrigger inputs to any of the pattern controller’s eight trigger inputs. There isan 8-position switch (SW7, SW8, SW9, SW10) for each of the remotejunction box’s trigger inputs that is used to assign triggers.

The double-stack D-shell connectors (X8, X7, X1) are used to daisy-chaintheir signals to other remote junction boxes. The only exception is whenusing the 2 trigger/6 gun configuration. In which case, the second 9-pinD-shell connector is dedicated to gun signals E and F.
