Operation - Agilent Technologies TriScroll 800 Installation And Operation Manual

Operation

In order to reach ultimate vacuum, the pump must be left
running for about one hour with the inlet sealed.
Unlike conventional oil-sealed pumps, Agilent's dry scroll
pumps do not have fluid to cleanse them of accumulated dust
and debris. Run the pump periodically at atmosphere for a
minute or two to flush out the pump. Flush the pump regularly
and adjust this schedule according to your specific conditions.
Startup Procedure
1. Be sure that the vacuum system isolation valve is closed.
2. Turn on power to the pump.
NOTE Pump operation is interlock dependent.
The provided mating connector must be
plugged into P1 to start the pump.
NOTE
The integrated VPI solenoid must be
connected to I/O P2 with the provided
communications cable prior starting
the pump.
NOTE When the controller is switched on, an
electronic self-test occurs, during
which an orange LED illuminates for
one second and the turns off for two
seconds. During this time, the pump
will not start.
This self-test time is not required if the
pump is already powered, as when
remotely or serially operated.
3. Open the isolation valve.
Shutdown Procedure
1. Close the vacuum system isolation valve. This prevents
debris in pump from being transported into the vacuum
system.
2. Turn off power to the pump.
