2.4 Electrical data
If your T-Station uses an E2M1.5, the motor start-up current is drawn for less than one second, so you must use slow-
blow fuses to prevent unnecessary fuse failure when the pump starts. If you use the pump at temperatures lower
than 12 °C (53.6 °F), the start-up current will be drawn for longer; this may cause the motor thermal overload device
to open.

2.5 Pumping media
CAUTION
Do not use the turbo pump to pump gases containing more than 20% oxygen unless the pump is gas purged. If
you do, the lubricant will polymerise and the pump may fail prematurely.
CAUTION
Do not use a turbo pump to pump mercury vapour and do not allow mercury (for example, from a McLeod gauge)
to come into contact with the pump. If you do, the pump rotor may corrode and fail.
Note: Concentrations of gases may be modified by the compression of the pump.
The turbo turbo pump is designed to pump the following residual gases normally used in high-vacuum systems:
You can use the pump to pump oxygen and water vapour, subject to the following conditions:
Oxygen - when the pump is purged by an inert gas, oxygen can be pumped at concentrations above 20% by
volume. Refer to the EXT75DX instruction manual (B722-40-880) for Purge gas specification. However, if the
pump is not purged, the oxygen concentration must be less than 20% by volume.
Water vapour - you must ensure that vapour does not condense inside the pump.
WARNING
Vent dangerous gases and gas mixtures safely, do not expose people to these gases. If pumping
hazardous gases or vapours, observe the safety recommendations of the supplier of the gas/
vapour.
WARNING
Do not use the turbo pump to pump pyrophoric or explosive gas mixtures, as it is not suitable for
this purpose. The pump and its connections are not designed to contain an explosion.
WARNING
Do not expose any part of the human body to vacuum.

If you wish to pump a gas not in the list above, contact your supplier for advice. If you do not contact your supplier,
you may invalidate the warranty on the pump. The pump is not suitable for pumping aggressive or corrosive gases.
2.6 Materials exposed to gases pumped
The following materials and component types are exposed to the gases pumped:
Aluminium alloys, stainless steels, fluoroelastomer and nitrile O-rings, hydrocarbon lubricant, felt, rare earth
magnets, silicon nitride, phenolic resin, carbon-fibre reinforced epoxy resin, fire retardant polypropylene,
polyamide and PVC.
2.7 Vent gas specification and vent control data
Although the pump may be vented to atmosphere, high relative humidity of the air may greatly increase the
subsequent pump-down time. To reduce pump-down times you should vent with dry, clean gases. Refer to the DX
turbo pump manual (B722-40-880) for the vent valve connection and refer to Section 4.3.3 of this manual for a
description of the vent options available on the T-Station and how to configure them.

Installation
3.3 Locate the T-Station
CAUTION
When locating the T-Station, care should be taken not to restrict the ventilation grid located under the base of
the T-Station. Failing to observe this may result in over heating of the turbomolecular pump.
3.4 Bench-top fixing
There are two M8 fixing points located at the rear of the T-Station base (refer to Figure 1, item 12). Using suitable
brackets or straps (not supplied), we recommend that you should secure the T-Station to your bench-top to prevent
excessive movement in the unlikely event of a pump failure. Please note, we cannot provide straps or brackets as
we unable to determine the best type fixing for your bench-top location. We recommend you should source or
fabricate these fixings locally.
3.5 Fill the rotary pump with oil
If the T-Station uses an E2M1.5 rotary vane pump, you must fill it with the correct quantity of oil (supplied with the
equipment) before you operate the equipment. For further information refer to the EM Rotary Vane Pump manual
A371-32-880.
Fill the pump with oil as described below.
1. Remove the oil filler-plug.
2. Pour oil into the pump until the oil-level just reaches the MAX mark on the bezel at the top of the sight-glass. If
the oil-level goes above the MAX mark, remove the drain-plug and drain the excess oil from the pump.
3. After a few minutes, recheck the oil-level. If the oil-level is now below the MAX mark, pour more oil into the
pump.
4. Refit the oil filler-plug. Tighten the plug firmly by hand. Do not over tighten.
WARNING
Heavy objects can cause muscle strain or back injury. The mass of the T-Station will differ
depending on the model supplied, refer to Section 2.1 for the equipment mass.
WARNING
Important: The turbo pump used on the T-Station stores a large amount of kinetic energy when it
is running at full speed. In the unlikely event of a malfunction (rotor seizure), the stored energy
could cause a slight movement of the T-Station platform. If the T-Station is operating on a bench-
top, we advise that the following steps should be taken:
Position the T-Station at least 10-15 cm away from the edge of the bench-top and adjacent
devices.
and or,
Tether or fix the T-Station to your bench-top, see Section 3.4.

Installation
D395-93-880 Issue A
3.6 Connect the T-Station to your vacuum system
The turbo pump can be securely fixed to the vacuum system via the inlet-flange. Make sure that the pump-inlet and
all components fitted to the pump-inlet are clean and dust-free. If the pump-inlet is not kept clean, the pump-down
time may be increased.
If the pump has a CF flange, use the copper compression gasket supplied with the pump and use a full
complement of bolts to connect the inlet-flange of the pump to the vacuum system.
If the pump has an ISO flange, use a minimum of four claw clamps (each torque to 10 Nm) to connect the
inlet-flange of the pump to the vacuum system. Alternatively, use a rotatable collar and the combined inlet
screen and trapped O-ring supplied with the pump to connect the inlet-flange of the pump to the vacuum
system; use a full complement of bolts with the rotatable collar.
If the pump has an NW flange, use the centring ring supplied with the pump and a metal NW clamp to
connect the inlet-flange of the pump to the vacuum system.
All inlet flange bolts must be re-tightened once the system is under vacuum. Ensure that no torques or other forces
are transmitted to the pump from the vacuum system or the associated pipelines.
3.7 Connect to your exhaust extraction system
Note: This section applies to E2M1.5 versions only.
The exhaust system must be configured so that the maximum pressure at the pump outlet does not exceed 0.5 bar
gauge (1.5 bar absolute, 1.5 x 105Pa) at full pump throughput. Make sure that the exhaust pipeline cannot become
blocked. If you have an exhaust- isolation valve, make sure that you cannot operate the pump with the valve closed.
WARNING
Connect the turbo pump inlet to your vacuum system before applying power to the T-Station. This
will ensure that the pump cannot operate accidentally causing injury.
WARNING
If you install your vacuum system directly onto the T-Station, the weight of the system must be no
more than 10 kg and the centre of gravity must be positioned laterally within the bounds of the
base plate. If this is not the case, the vacuum system must be supported to ensure that the
T-Station does not topple.
WARNING
Vent dangerous gases and gas mixtures safely, do not expose people to these gases. If pumping
hazardous gases or vapours, observe the safety recommendations of the supplier of the gas/
vapour.

3.8 Connect the electrical supply
CAUTION
Always make the electrical connections to the T-Station after the equipment has been installed on your vacuum
system. Always disconnect the electrical supply from the T-Station before removing the equipment from the
vacuum system.
Check that your electrical supply is suitable for this equipment. Refer to Table 3 for the electrical requirements for
this equipment. Make the electrical connection to the T-Station using a cable fitted with an IEC60320 connector. A
range of suitable cables is available from your supplier.
3.9 Configure the T-Station
As supplied from the factory, the T-Station 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*.
* This operation refers to systems which have been fitted with an Edwards TAV vent valve (optional accessory). For
more vent options refer to Section 4.3.3.
3.9.1 Turbo pump delay
The T-Station can be configured to delay the turbo pump after the backing pump has started (refer to Section 4.3.4),
this 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 your T-Station uses an XDD1
diaphragm pump. Below the chart shows the recommended delay period for a turbo / XDD1 pump combination.
WARNING
Ensure that the electrical installation of the T-Station conforms with your local and national safety
requirements. It must be connected to a suitably fused and protected electrical supply and a
suitable earth point.

3.9.2 Connecting a vacuum gauge
CAUTION
Do not connect Barocel capacitance manometers to the T-Station gauge connector. Doing so will result in
damage to the gauge and will invalidate the warranty.
A single compatible active gauge can be fitted to the T-Station. Fit the gauge using an Edwards active gauge cable
into the gauge connector located on the side of the controller housing (refer to Figure 1). For active gauge control
and set-up refer to Section 4.3.2.
The following Edwards active gauges are suitable for use with the T-Station:
APG100 Active Pirani vacuum gauge
APGX-H Active Linear Convection gauge
AIM-X Active Inverted Magnetron gauge
WRG-S Active Wide Range gauge
ASG Active Strain gauge

Installation
3.10 Commissioning the installation
After you have installed the T-Station, use the following procedure to test the system.
1. Make sure that all the electrical connections are secure.
2. Switch on the electrical supply and your exhaust-extraction system (if available).
3. To operate the system press the START/STOP key. Check that the equipment operates as described in
Section 3.9.
4. Check that the turbo pump reaches normal speed. If the pump inlet is valved or capped off, it should take
approximately 100 - 150 seconds for the turbo to reach normal speed. If you have attached a vacuum chamber to
the pump inlet, this time may take longer.
5. To turn OFF the system, press the START/STOP key followed by the ENTER key to confirm. Check that the
equipment closes down as described in Section 3.9.
For full operational details and how to navigate using the front panel control key pad refer to Section 4.3.
