Connecting Output Contacts

(Optional)
A3EN-04-[3V-A-AAXP]-12
Follow this procedure to connect the standard output contacts that are
provided on all units. If you do not wish to connect any outputs, skip to
the next procedure, Connecting External Devices to the Pattern Control.
Output contacts allow you to automatically activate other equipment or to
activate devices for remote monitoring of the unit's operations.
Table A 1-1 describes the standard output contacts. If your unit has an
optional input/output (I/O) board, there are additional outputs and several
inputs you can connect. Refer to Series 3000V Input/Output Board in the
Options section.
Table A 1-1 Standard Output Contacts
Output Contact
System Warning Used to signal a device that will alert remotely
located operators of a warning condition
System Fault Used to signal a device that will alert remotely
located operators of a system fault condition. This
output is typically used to turn on a light or to sound
an alarm.
System Ready Used to signal a device that will alert remotely
located operators that the system is ready for
operation (up to temperature) or that the unit's
pump is on. This output is typically used to send a
ready signal to a production line so that the line
turns on only when the unit is ready to pump
adhesive.
3. If you have not already done so, open the electrical enclosure. Refer
to Opening the Electrical Enclosure in this section.

plug from one of the larger holes on either the back side or the bottom
of the unit (whichever is most convenient for your operation). Avoid
contact with any printed circuit boards.
