Other Active Safety Features
Components approved in accordance with standards EN 60204-1 (safety of machinery):
•
Emergency stop (as per IEC 947-5-1): the emergency stop is located on the control display; it activates immediate shut-
down of the following components: oven, laser, motors, blower, as well as the pneumatic drives,
•
Safety switches (as per EN 1088): these devices isolate the laser when opening one of the main doors or the scan head .
They make it possible to lock and unlock the main doors,
•
Electrical isolation : this involves the main isolating switch located on the printer's connection panel . When the printer is
off, this device isolates the printer from the network, and enables electrical isolation .
Additional components :
•
Software in the DMP system automatically initiates immediate equipment shutdown if certain unsafe conditions are
detected during operation,
•
Ground fault interrupter and over-current circuit-breaker,
•
Locking key on the control display: the machine cannot be switched on unless the key is in the ON position .
Machine Safety
DMP equipment includes following safety features:
•
Detection of a drop in air pressure: control indicates a fault if the air feed pressure drops below the required pressure,
•
Detection of chamber temperature: inability to open the doors if the temperature is above +50°C (+122°F),
•
Protection of the motors: the axis stop if an abnormal temperature is observed,
•
Protection of blower: the blower stops if an abnormal temperature is observed,
•
Rotate of the airlock (the sas) when airlock door is open,
•
Anti-collision system: the HMI (Human Machine Interface) and the various sensors fitted on the ProX
possible to avoid collisions between moving system components,
•
Protection of the Laser: control of the diodes temperature, control of the back-reflexion absorber temperature and
control the integrity of the fiber,
•
Protection of the scan head: control of the head temperature .
•
Lock-out/tag out on the main power switch: when the main power switch is locked in the OFF position, the machine
cannot be switched on .
ELECTRICAL SAFETY
3D Systems recommends explosion-proof wiring for the room where the DMP is operating and where the materials are
stored .
To prevent electrical shock, DMP equipment will not operate unless all external panels are installed and all electrical safety
interlock circuits are closed .
ELECTRICAL HAZARD: Hazardous voltage exists inside the enclosures of all DMP equipment . Injury or
death from electrical shock can result if you remove external panels or try to defeat safety interlocks .
Panels should only be removed, and interlocks should only be defeated, by 3D Systems certified service
personnel .
ELECTRICAL HAZARD: Verify your facility's electrical service ratings before connecting power to any DMP
equipment. Power must only be connected by a certified electrician.
ELECTRICAL HAZARD: Do not open the panel behind disconnect switch! Live voltage present . This should
only be opened by qualified personnel after power is disconnected from the facility's power circuit/
breaker panel .
All DMP equipment is designed to minimize operator exposure to electrical hazards during normal operations . All exposed
electrical circuits are inside limited-access cabinets . This is to separate the operator from service and maintenance areas .
When operating any DMP equipment, keep the following electrical safety points in mind:
•
Only 3D Systems certified service personnel should operate DMP equipment with access panels or service doors open.
•
Heed high voltage warning signs and labels .
•
Take common-sense safety precautions when operating any electrical equipment .
•
After any change to the electrical wiring, make sure the equipment is properly grounded .
