Connect the electrical supply
WARNING:
Ensure that the electrical installation of the pump conforms with all local and national
safety requirements. It must be connected to a suitably fused and protected electrical
supply with a suitable earth point.
CAUTION:
Always make the electrical connections to the T-Station 85 after the equipment has been
installed on the vacuum system. Always disconnect the electrical supply from the T-Station
85 before removing the equipment from the vacuum system.
Check that the electrical supply is suitable for this equipment. Refer to
Table 22
on page 42
for the electrical requirements for this equipment.
Make the electrical connection to the T-Station 85 using a cable fitted with an IEC60320
connector.
A range of suitable cables is available from the supplier.
Configure the T-Station 85
As supplied from the factory, the T-Station 85 will control the system as follows:
System start is selected:
•
The TAV vent valve will close.
•
The backing pump will turn on.
•
The turbomolecular pump will start accelerating up to full rotational speed.
System off is selected:
•
The backing pump will turn off.
•
The turbomolecular pump drive will turn off and the pump will start to decelerate.
•
The TAV vent valve will open fully from 50% of full rotational speed.
Turbo pump delay
The T-Station 85 can be configured to delay the turbo pump after the backing pump has
started.
Refer to
Turbo setpoint screen
on page 22. The delay is helpful to prevent the turbomolecular
pump from accelerating under high pressure for a prolonged period if the volume being
pumped is greater than 2 litres. This option is especially useful if the T-Station 85 uses an XDD1
diaphragm pump.
Figure 2
on page 15 shows the recommended delay period for a turbo / XDD1 pump
combination.
*
This operation refers to systems which have been fitted with an Edwards TAV vent valve (optional
accessory). For more vent options refer to
Vent valve screen
on page 20.
