Page 9: Safety And Compliance
Safety symbols The safety symbols on the products denote areas where care and attention is required. The following safety symbols may be used on the T-Station 85 or throughout the product documentation. Warning/Caution An appropriate safety instruction should be followed or caution to a potential hazard exists. -
Page 10: General Description
Both system variants use a nEXT85 turbomolecular pump. The T-Station 85 is controlled by an easy to use touch pad control module. A single gauge input included can be connected to a range of Edwards active gauges allowing for pressure measurement and/or control management of the turbomolecular pump. -

Station 85. This will ensure that the pump cannot operate accidentally causing injury. WARNING: If installing the vacuum system directly onto the T-Station 85, 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. -
Page 14: Connect The Electrical Supply
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. -
Page 15: Connect A Vacuum Gauge
Connect a vacuum gauge A single compatible active gauge can be fitted to the T-Station 85. 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 on page 10, item 6). -

Page 25: Gas Ballast Control (E2M1.5)
If the electrical supply to the T-Station 85 fails when the turbo pump is rotating, the motor of the turbo pump is used as a generator. The regenerated power is used to maintain the control system and the display. -
Page 26: Maintenance
Maintenance plan WARNING: If the turbo pump is removed from the T-Station 85 platform, it is important to retain and reuse the same fixing screws. If any of these screws are lost or cannot be used, the following type M5 x 12 mm CAP HD high tensile class 12.9 must be used. If this warning is ignored and the turbo pump seizes, the stored energy in the turbo pump may cause some or all of the screws to fail. -
