Vac Control function
➨
Vacuum control to a preset vacuum value
• Operation on demand of a speed controlled pump (NT VARIO)
Preselections
+
Use the selection knob to select the parameters. All parameters can
be altered even while operation control is running.
+
Set vacuum
:
The ”
Set vacuum
” is the set point for vacuum control
with pinpoint precision for NT VARIO pumps.
The ”
Set vacuum
” is adjustable in a range of 1-795 Torr (1-1060 mbar)
or can be set to ”Turbo”. The selection ”Turbo” leads to the optimum
backing pressure for a turbomolecular pump.
+
Speed:
The maximum motor speed can be preselected (to control the
pumping speed).
The ”
Speed
” is adjustable in a range of 1-100% or can be set to ”HI”.
The selection ”HI” (recommended) provides the optimum pumping
speed of the pump and therefore an optimum ultimate vacuum.
+
Maximum
:
An upper pressure limit can be preselected. The pump
switches off if the pressure limit is exceeded, e.g., at the end of suc-
tions or filtrations. The pressure limit is only active once the pressure
has gone below ”
Maximum
”.
The ”
Maximum
” is adjustable in a range of 794-1Torr (1059 - 1 mbar)
(at the least 1 Torr (mbar) higher than the ”Set vacuum”) and to ”Off”.
”Off” means that no ”Maximum” value is preset.
+
Delay:
”
Delay
” determines the time the coolant valve remains open
after the process has been stopped.
The ”
Delay
” is adjustable in a range of 1-300 minutes or can be set to
”Off” (”Off” means that the coolant valve closes immediately when the
process stops.).
+
Duration:
”
Duration
” determines the total process time since control
start.
