10. Printing with nitrogen installation
WARNING!
•
The built-in oxygen level detector is not a certified device and the signal
cannot be treated as the only warning. Keep the LISA PRO printer and the
nitrogen bottle in well-ventilated rooms.
•
If you hear an alert, open the windows/ventilate the room and leave the room.
•
If you feel any suspicious symptoms, immediately leave the room and go
outside/to a well-ventilated room.
WARNING!
•
Store in a well-ventilated place.
•
Do not inhale the gas.
•
Possibility of unsealing - gas has a suffocating effect on people by displacing
oxygen from the air. Too low oxygen concentration in the air can lead to
unconsciousness and death.
A. NITROGEN INSTALLATION - MESSAGES AND SOUND SIGNALS
1. If the nitrogen pressure becomes too high or too low, an intermittent sound signal is activated.
2. If the nitrogen pressure is too low, connect a proper nitrogen supply or the printing will stop in 3 minutes.
3. If the nitrogen pressure is too high,
a notification is displayed.
4. If the concentration of oxygen in the printer’s surroundings is too low, a continuous sound signal is activated.
5. If the oxygen level in the printer’s surroundings drops below 17%, a continuous sound signal is activated and the
printer displays a message „LOW OXYGEN LEVEL” on the touchscreen.
B. PREPARING INSTALLATION TO PRINT
1.
To print in the nitrogen environment (required for PA11),
connect the nitrogen supply to the Nitrogen inlet nipple
13
.
It can be connected at any time, even when the printer is
off, as it has an electrovalve built-in.
2. Make sure that the nitrogen pressure is between 4 and
8 [bar] during the whole process. Remember that it may
change if you’re using a bottle and a pressure regulator.
3.
Start the printing process as usual. If the xxx.scode file is
properly prepared, the printer will automatically control the
use of the nitrogen chamber.
