Safety Control System (SCS)IntroductionThe 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 workingwith the machine. The printer is equipped with Emergency Stop Buttons, several InterlockSwitches and an Automation Interface for auxiliary equipment (handling the printer outputmaterial). Including a Stop Strip on either side of the Gantry. A green beacon light located on theCarriage indicates the Active/Disabled status of the SCS of the printer.Components of the Safety Control SystemThere are various elements to the SCS:1. Emergency Stop Buttons2. Maintenance Access Door Interlock Switch3. Carriage Guards (Left and Right)4. UV Lamps Housing (Home and Away)5. Automation Interface6. 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 UVcuring system. Emergency Stop Buttons are installed on both ends of the Gantry and on the UserInterface Desk.2. Maintenance Access Door Interlock Switch:The Maintenance Access Door is located at one end of the printer and allows access to thebottom of the carriage to perform Manual Printhead Maintenance and to swab printheads. Whenthe door is open, the Carriage, the Gantry motion motors and UV curing system are disabled.3. Carriage GuardsThe Carriage Guards are located on both sides of the carriage. When one of the Carriage Guardsdetects 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 willdeactivate the complete UV curing system (home and away).NOTEThe UV lamp will still be hot.5. Automation InterfaceThe 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 StripOn either side of the Gantry a stop strip is installed. When pressing this Stop Strip (at anylocation along its length) this will trip the SCS in the same manner as the Emergency Stop. Allprinter 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 turnedcounter-clockwise. Other actuators will reset itself after release. Upon release, no motion can beinitiated without acknowledgment by the operator from the user interface desk.Safety Control System (SCS)Chapter 2 - Safety Information 29
