TriScroll 800 Inverter Vacuum Pump
DRAFT 10/9/14
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.
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.
Maintenance
Personnel responsible for pump operation and
maintenance must be well-trained and aware of the
accident prevention rules.
If a pump is to be discarded, it must be disposed of in
accordance with specific national and local standards.
NOTE Pump operation is interlock depen-
dent. The provided mating connec-
tor must be plugged into P1 to start
the pump.
NOTE The integrated VPI solenoid must be
connected to I/O P2 with the pro-
vided 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.
WARNING ❑ Death may result from contact
with high voltages. Always take
extreme care and observe the acci-
dent prevention regulations in force.
❑ When the machine is powered
up, be careful of moving parts and
high voltages.
❑ If you have to perform mainte-
nance on the pump after a consider-
able time in operation, allow the
pump to cool as the temperature of
the outer surface may be in excess of
55 °C (131 °F).
❑ Always disconnect your power
supply to the pump before beginning
maintenance work.
NOTE Before returning the pump to the
factory for repair, the Return Autho-
rization sheet attached to this
instruction manual must be com-
pleted and sent to the local sales
office. A copy of the sheet must be
inserted in the pump package before
shipping.
