Inerting phases process
The inerting process must follow the 2 phases in this order : manufacturing chamber inerting at rst, then
process lter inerting. Do not activate the lens cleaner turbine if the process lter is not connected to the
printer. Make sure the lter is well connected to the printer before starting the inerting process.
1. Click on Start inerting (1) : Gas and purge activated –
Regulation mode activated – Lens cleaner turbine OFF
and external vessel valves closed. This step will only
inert the manufacturing chamber.
2. Once the O2 value is lower than the safety limit, Start
lens cleaner turbine button is enable. Click on it (2) to
activate the lens cleaner turbine : the vessel valves will
open, allowing the fume vessel inerting.
3. Once the O2 value is lower than the Minimum Oxygen Value To Produce, then click on Produce (3) to go to the
Manufacturing menu.
If the O2 level goes higher than the safety limit (during manufacturing or after lter vessel replacement), the lens
cleaner turbine will stop automatically (and the external vessel valves close). It will trigger an oxygen error (4). Click on
Validate, then proceed again to the inerting phases process up to get the O2 level below the safety limit.
