Safety Control System (SCS)

Introduction
The Arizona 6100 XTHF Mark II series printers are equipped with a Category 3, Performance Level
'd' Safety Control System (SCS) to protect the operator and any other personnel when working
with the machine. The printer is equipped with Emergency Stop Buttons, several Interlock
Switches and an Automation Interface for auxiliary equipment (handling the printer output
material). Including a Stop Strip on either side of the Gantry. A green beacon light located on the
Carriage indicates the Active/Disabled status of the SCS of the printer.
Components of the Safety Control System
There are various elements to the SCS:
1. Emergency Stop Buttons
2. Maintenance Access Door Interlock Switch
3. Carriage Guards (Left and Right)
4. UV Lamps Housing (Home and Away)
5. Automation Interface
6. Stop Strip (Front and Rear)
1. Emergency Stop Buttons:
Activating one of the Emergency Stop buttons will stop all printer motion and turns off the UV
curing system. Emergency Stop Buttons are installed on both ends of the Gantry and on the User
Interface Desk.
2. Maintenance Access Door Interlock Switch:
The Maintenance Access Door is located at one end of the printer and allows access to the
bottom of the carriage to perform Manual Printhead Maintenance and to swab printheads. When
the door is open, the Carriage, the Gantry motion motors and UV curing system are disabled.
3. Carriage Guards
The Carriage Guards are located on both sides of the carriage. When one of the Carriage Guards
detects an obstruction, all printer motion stops and the UV curing system is turned off.
4. UV Lamp Housings (Home and Away)
Both UV lamp housings have an Interlock Switch. When a UV lamp housing is opened this will
deactivate the complete UV curing system (home and away).
NOTE
The UV lamp will still be hot.
5. Automation Interface
The machine is equipped with an interface to connect to the SCS of the auxiliary equipment.
Pressing an emergency stop on the Arizona machine will result in a stop of the auxiliary machine
(and vice versa). This interface is configurable.
6. Stop Strip
On either side of the Gantry a stop strip is installed. When pressing this Stop Strip (at any
location along its length) this will trip the SCS in the same manner as the Emergency Stop. All
printer motion will be stopped and the UV curing system will be switched off.
To re-activate the printer after an Emergency Stop Button is pressed, it needs to be turned
counter-clockwise. Other actuators will reset itself after release. Upon release, no motion can be
initiated without acknowledgment by the operator from the user interface desk.
