Safety Interlock System
Introduction
The printer has three Emergency-Stop switches. 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. Activating 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
counterclockwise. Upon release of the button, no motion can be initiated without
acknowledgement 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, 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.
