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. 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 counter-clockwise. Upon release of the button, no motion can
be initiated without acknowledgment 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.
