CONFIGURATION OF REGULATION HD
The high-vacuum turbine is cooled by the volume of air passing through the extraction system. When
only a few torches are used, the volume of air is not sufficient for cooling the extraction turbine.
In that case, the HD regulation must be adjusted appropriately using the branch damper and the
system connection.
On the UI screen, in the HD REGUL SETTINGS,
-
Read the power consumed in kW when all the downward passages from the system are shut (read the
value on the home screen of the UI or the HD regulation setting screen).
-
In the 100% OPEN line, enter the read value.
-
In the 100% CLOSED line, add 5 kW to the read value.
-
Set a 10 to 15 second delay to avoid unintended changes when the operating point varies depending on the
use of fume extraction torches.
NB: The values announced above are for guidance must be adjusted when the unit is put into service.
