5.14 Operation of the iF system components
Ensure that you do not over-pressurise the vacuum system if you switch on the purge gas flow when the pump(s)
are not on.
Notes: The gate valve must be connected to the iF system through an iF Interface Module with an Auxiliary
Interface Card.
When you manually start the FDP pump or the HMB pump, the pump will only operate for 10 seconds and
will then automatically be switched off again.
Although you can select and use the Setup/Service/Manual/MB menu, this will have no effect on the HMB
pump; that is, you cannot use the menu to manually switch the HMB pump on and off.
In normal operating conditions, the components of the iF system are operated automatically.
If necessary (for example, for fault finding purposes), you can control the operation of iF system components
separately:
Use the Setup/Service/Manual/Gas Module menu to control the operation of the Gas Module (that is, turn
the nitrogen supply, gas-ballast and inlet-purge flows on and off).
Use the Setup/Service/Manual/Valve menu to control the operation of the gate valve (that is open or close
the valve).
Use the Setup/Service/Manual/DP Only menu to control the operation of the FDP pump (that is, switch the
FDP pump on and off).
5.15 Operation of the load-lock pump
Note: Operation of the iF system with high inlet pressure may result in shaft-seal pressure warnings (refer to
Table 18): the operation of the iF system will not be affected, and you can ignore these warnings.
If you have connected a load-lock pump to the iF system through an Interface Module, you can use the following
menus to control the operation of the load-lock pump:
Switch On.
Switch Off.
Setup/Service/Manual/Load lock pump.
Ensure that it is safe to start the iF system. If you do not (and for example, maintenance is being
performed on components downstream of the iF system), you could cause injury to people.
