WARNING: NEVER DISABLE OR OVERRIDE ANY SAFETY INTERLOCK DEVICE ON ANY DMP EQUIPMENT.
OPERATING EQUIPMENT WITH INTERLOCKS DEFEATED CAN CAUSE EQUIPMENT DAMAGE, INJURY, OR DEATH. IF
YOU SUSPECT A SAFETY INTERLOCK DEVICE IS NOT WORKING PROPERLY, DO NOT OPERATE YOUR DMP
EQUIPMENT. DISCONNECT POWER FROM THE EQUIPMENT AND CONTACT 3D SYSTEMS CUSTOMER SUPPORT FOR
ASSISTANCE.
OVERVIEW OF THE SAFETY INTERLOCKS
Glove port sensors Detects if the glove ports are open or closed. If open, the vacuum pump and blower
cannot start and no print job can be started.
Argon pressure sensors Located in the pneumatic cabinet, the argon pressure sensor will detect if the pressure
of the compressed air goes out of range. If so, the system will go into alarm mode, a
warning message will appear on DMP Deposition and the print job will stop.
Compressed air pressure sensor Located in the pneumatic cabinet, the compressed air pressure sensor will detect if the
pressure of the compressed air goes out of range. If so, the system will go into alarm
mode, a warning message will appear on DMP Deposition and the print job will stop.
Relative pressure sensor
process chamber
Measures the relative pressure inside the process chamber. When out of spec, the sys-
tem will go into alarm mode, a warning message will appear on DMP Deposition and the
print job will stop. The argon and compressed air supply will be closed.
Oxygen (O
2
) pct sensor Measures in the range in percentage (%) from zero (0) to 25 %. If the level of Oxygen (O
2
)
gas is over 2%, the laser will stop or not start.
Oxygen (O
2
) ppm sensor Measures in the range in Parts Per Million (ppm) from zero (0) to 1000 ppm. If the level of
Oxygen (O
2
) gas is over 230 ppm, the laser stops or does not start.
Process door sensor Detects the position of the door to the process chamber. If the door is open, the print
task will stop or not start.
Argon and compressed air supply will be closed.
Vacuum pump will be shut off.
Module blower, coater and laser will not work.
Liquid sensor Detects whether liquid is present at the bottom plate of the laser compartiment.
If the liquid sensor detects liquid, the printer module will react the same as in case of an
emergency off.
Over-current circuit-breaker If the over-current circuit-breaker detects an over-current the system will stop or not
start.
Main power switch In the off position due to a lock-out / tag out procedure.
OVERVIEW OF THE SAFETY INTERLOCKS
Sensor on the doors of electrical
cabinet
Will trip main power switch if door is openen when By-pass is off.
Emergency off See §: What happens in case of Emergency off
Slave OK Both signals needs to be OK. If not, interconnection valves will remain closed.
Hold-to-run If the process door is closed and the glove ports are open, the hold-to-run button inside
the process chamber will enable the coater.
If the process door is closed and the glove ports are closed and locked, the hold-to-run
button on the front control panel will move the coater.
