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.
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.
2. If the T-Station 85 is damaged, notify the supplier and the carrier in writing within three days; state the item number of the T-Station 85 together with the order number and the supplier's invoice number.
Procedure for filling the pump with the recommended oil. If the T-Station 85 uses an E2M1.5 rotary vane pump, it must be filled with the correct quantity of oil (supplied) before operating the equipment. For further information refer to the EM Rotary Vane Pump manual A371-32-880.
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.
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.
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).
D395-94-880A - Operation Operation WARNING: Do not attempt to move the T-Station 85 while the turbo pump is rotating. Doing so may cause severe damage to the pump and could cause injury. CAUTION: To familiarise yourself with the vacuum pumps installed on the T-Station 85, it is advisable...
Units screen Start up When applying power to the T-Station 85 all LEDs in the display will light for 2 seconds to confirm operation. The software version will then be displayed for a further 2 seconds. If you need to contact Edwards for support regarding the T-Station 85, please have this software version number available.
D395-94-880A - Operation Figure 4 Menu structure Turbo screen When the turbo screen is selected, the turbo LED is lit and the speed of the turbomolecular pump is displayed in percentage of full speed. If no turbo pump is connected the display shows "---". Page 18...
D395-94-880A - Operation Figure 5 Turbo screen Start the pump with the turbo screen When the START/STOP key is pressed, both the turbo and backing pumps start. The display shows the turbo pump is accelerating by flashing the top left portion of the percentage sign. When the turbo pump reaches normal speed (>80% default) the percentage sign stops flashing and remains steady.
D395-94-880A - Operation Connect a gauge When a gauge is first connected the display shows "ID" followed by a number to identify the new gauge. If the gauge is an Active Strain Gauge (ASG), the display then goes to ASG range select, otherwise the display reverts to showing the pressure reading.
D395-94-880A - Operation 2. To change the vent valve setting press the ENTER key, then use the NEXT key to choose between 50%, Ctrld and FAN. 3. Press the ENTER key again to confirm the selection. Table 6 Vent valve screen Normally open vent valves.
D395-94-880A - Operation Turbo setpoint screen The turbo setpoint screen is used to configure the start delay of the turbo pump. When the turbo setpoint screen is selected, the TSP LED is lit and the current setpoint is displayed. The default is "OFF". The turbo setpoint menu is not available if the turbo pump is running or the selected units are volts.

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.
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.
Factory default settings Procedure to return the T-Station 85 to the factory default settings. 1. Remove the mains power from the T-Station 85. 2. Press the NEXT key and hold it down whilst reapplying mains power. Continue holding down the NEXT key until "Err01"...
40. Cause The operating voltage is incorrect. Remedy Check the voltage supply matches the T-Station 85 voltage requirements. Refer to the electrical rating label located at the rear of the T-Station 85. Ultimate pressure cannot be reached Cause Pressure is limited by water vapour.
D395-94-880A - Fault finding The turbo pump is very noisy or there is excessive vibration or both Cause Listed in Troubleshooting section of the turbo pump manual. Remedy Refer to the Troubleshooting section of the turbo pump manual. See General description page 10.

D395-94-880A - Fault finding Error Meaning Possible cause/remedy Number Pump errors Turbo pump fault Inspect the LEDs on the turbo pump podule for status information. For more detailed fault codes, press and hold the ENTER key (whilst Err41 is showing) to display the turbo pump system status word.
Stop the pump with the turbo screen page 19. 2. Isolate the T-Station 85 from the electrical supply and disconnect it from the vacuum system. 3. Drain the oil from the backing pump (only applicable to the E2M1.5 rotary vane pump)

Not connected Electrical data If the T-Station 85 uses an E2M1.5, the motor start up current is drawn for less than one second, so slow-blow fuses must be used to prevent unnecessary fuse failure when the pump starts. If using the pump at temperatures lower than 12 °C (53.6 °F), the start up current will be drawn for longer;...
