CAUTION

 

Check the complete installation thoroughly before proceeding. 

 

 

Start up 

Set the Remote Vacuum Controller (RVC) “Interlocks” key switch to ON and the power switch to On (I) 
 
On your PC, start Process Eye Professional. The software will detect that the RVC2 is fitted and the Remote 
Vacuum Controller status and control panel will be available at the bottom of the Process Eye Professional 
window.   
 
To start the Vision 2000C/E vacuum system, click on the turbopump button.   
The colour of the button indicates the status:  

Red = off 
Yellow = starting 
Green = running at full speed 

 
More information about the RVC operating software can be found in the manuals for the RVC2 and Process Eye 
Professional.  
 
The Vision 2000C/E may also be started from the RVC2 directly. This is useful if the PC is disconnected or the 
Process Eye software is not running. To start the system from the RVC2, briefly press the PUMPS switch on the 
front panel.  Note that this control can also be used to turn the turbopump OFF. 
 
As soon as the Vision 2000C/E is started the SurgeProtector foreline valve should open (if tool vacuum is <3torr) 
and the turbopump will start. 
 
The turbo pump controller will indicate when the pump is up to speed and the Turbopump indicator in the RVC 
window will change from yellow to green.  Note that the turbopump controller will be programmed to a set-point 
of 95% of rated speed. 
 
After the turbopump has reached full speed, you may switch the RGA filament on, but we recommend waiting at 
least 10 minutes after the adsorbed gas load in the RGA vacuum chamber to reduce before switching a filament 
on. 
 
Switch the RGA filament on and look at the RGA chamber background spectrum using a Process Eye 
Professional Bar-Chart recipe (refer to the Process Eye Professional documentation for further details). 
 
The pressure is likely to be quite high but should be falling. If the pressure is very high switch the filament off and 
wait a little while for the pressure to fall.  
 
Now, check that the process valves work. Ensure that there is a good vacuum in the process chamber. The 
pressure in the process chamber must be below the corresponding sample-valve pressure set-point to permit 
you to open a sampling valve. 
 
With the Remote Vacuum Controller in the manual mode and a filament on, open the process valve. The process 
valve will open and you will be able to see a spectrum of the process chamber. 
 
Once you have established that the process valve is working correctly, close the valve.  Minimizing exposure to 
corrosive process gases when not actively monitoring them will protect RGA system operating life.
