Safety Interlock System

Safety Interlock System
Introduction
The printer has three Emergency-Stop buttons. The Maintenance Station drawer and the Carriage
Guard are also 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:
They 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.
Power-up Interlock Test for Carriage
On power-up, the Interlock System will not permit printer motion. the Carriage Guard Interlock
must be cycled to ensure the Interlock is functional and that the Carriage Guard is in place. Upon
cycling of the Carriage Guard Interlock, no motion may be initiated without acknowledgment of
the Operator from the operator control station.
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.
