Safety Interlock System

Introduction
The printer has three Emergency-Stop buttons. The Maintenance Station drawer is part
of the safety interlock system. A beacon light indicates the status of the safety system and
the printer.
Components of the Interlock System
Emergency Stop Buttons:
These are located on the Operator Control Station, and on each end of the Gantry. Acti-
vating an Emergency-Stop button stops all printer motion and turns off the UV curing
system.
To re-activate the printer after you press an Emergency Stop button, turn the button
counter-clockwise. Upon release of the button, no motion can be initiated without ac-
knowledgment of the Operator from the Control Station.
Maintenance Station Interlock Function:
The Maintenance Station is located under the carriage and provides access to perform
Printhead Maintenance and swab printheads. Carriage and Gantry motion motors are
disabled and UV lamps are turned off (if they were On), when the station drawer is open.
The Interlock system is automatically reset when the drawer is closed.
Beacon Light Status
A green beacon light is mounted to the top surface of the printer carriage. The purpose
of this light is to indicate basic printer status to the operator.
Beacon off: indicates the printer can be approached without caution. The machine cannot
initiate movement since the interlock Safety System has disabled all motion and hazardous
hardware.
Beacon on: indicates the printer is powered up and ready to initiate motion. This tells
an operator to approach the machine with caution, because it can initiate motion at any
moment.
