Introduction Scope and definitions This manual provides installation, operation and maintenance instructions for the Edwards GXS dry pumping systems. The dry pumping system must be used as specified in this manual otherwise the protection provided by the equipment may be impaired.
There are various different ways to control the dry pumping system and monitor status. The user can manually press controls on the front panel and monitor LEDs on the front and rear of the dry pumping system. The Edwards Pump Display Terminal (PDT) gives further functionality for set up and status monitoring.
A suitably trained and supervised technician must install the dry pumping system. Users can be trained by Edwards to conduct the tasks described in this manual, contact your local service centre or Edwards for more information. Do not remove the temporary cover or blanking plate from the dry pumping system inlet and exhaust until ...

Incorporate flexible pipelines in the vacuum pipeline to reduce the transmission of vibration and to prevent loading of coupling joints. Edwards recommend using Edwards braided flexible pipelines. The pipelines should be rated for 110 °C. Adequately support vacuum/exhaust pipelines to prevent the transmission of stress to pipeline coupling ...
2, item 5) to the vacuum system. The inlet flange is not designed for use with a trapped O-ring or centering ring. Use Edwards half claw clamps when connecting an ISO style foreline flange to the dry pumping system inlet. Refer to Figure 3.
3, item 18 for location of the purge gas connection. Nitrogen and clean dry air are suitable purge gases for GXS dry pumping systems. To use a different purge gas, please contact Edwards. Check visually that the rotameter is not damaged when installing the dry pumping system.
Figure 3, item 4) go on. If the LEDs do not go on, contact Edwards. 2. Switch on the cooling water and purge gas supplies. 3. Ensure that the exhaust extraction system is not blocked (for example, that valves in the exhaust extraction system are open).
There are two types of gas module used on GXS dry pumping systems, refer to Section 2.4. The gas module configuration may be adjusted to suit process demands. Contact Edwards service personnel for instruction on how to access the gas valves menu (by the PDT) and for process-specific recommendations. For dry pumping systems using he medium duty gas module, there is an adjustable needle valve fitted to the purge pipe which enables the adjustment of the level of gas ballast to suit the application.
5. An adaptor cable, Edwards part number D373-70-754, is available as an accessory. The cable is 2 m long with a 5-way XLR plug on one end and a 9-way D connector socket on the other, allowing connection from the GXS dry pumping system to a standard COM port on a computer.
9 different Green Mode configurations but, by default, only one Green Mode is enabled. To enable alternative Green Mode configurations please contact your local Edwards service representative. To enable GREEN MODE/Standby mode when the pump is running and warmed up, press and hold the start button (Figure 1, item 3) for 5 seconds.
For these applications Edwards recommend carrying out a Smart Stop with Stop Time set to the maximum 3600 seconds. Once the pump has stopped, seal the inlet and exhaust to prevent migration of liquid/condensable back into the pump mechanism.
If in doubt, contact Edwards. Note: The high temperature alarms on Edwards dry pumping systems are dry pumping system protection trips and should be considered as an abnormal running condition. If a dry pumping system has tripped due to any high temperature alarm it should be investigated and the reason for the alarm established.
If the dry pumping system has automatically shut down because of high pump power, check that the pump is free to rotate before restarting the dry pumping system: contact Edwards. If the emergency stop switch on the front panel has been used to shut down the dry pumping system, the emergency stop switch must be reset before the dry pumping system can be restarted.
2. The exhausted liquid will never run clear. Exhausted liquid from a ‘clean’ pump has a similar viscosity to water (not thick and viscous) and is a light rust colour when seen exiting the exhaust. 3. Depending on the application, the solvent flush process may need to be repeated, contact Edwards for advice.
Particular caution should be exercised when working with fluorinated materials which may have been exposed to temperatures greater than 260 °C. Refer to Edwards Safety Data Sheets for detailed information.
Fluorinated materials in the dry pumping system include oils, greases and seals. The dry pumping system may have overheated if it was misused, if it malfunctioned or if it was in a fire. Edwards Safety Data Sheets for fluorinated materials used in the pump are available on request.
Do not use cleaning materials based on strong alkalis, aggressive or chlorinated solvents. Do not use cleaning materials containing abrasives. The following maintenance can be carried out on the dry pumping system between overhauls, contact Edwards for details and training:...
Contact Edwards for details and training. If the dry pumping system is not relocated for maintenance, ensure all supplies are locked out and tagged out before starting the following procedure.
Perchlorate Material - special handling may apply, refer to www.dtsc.ca.gov/hazardouswaste/perchlorate/ Edwards products are supported by a world-wide network of Edwards Service Centres. Each Service Centre offers a wide range of options including disposal. Refer to Section 7.2...
Edwards products, spares and accessories are available from Edwards companies and distributors world-wide. These centres employ Service Engineers who have undergone comprehensive Edwards training courses. Order spare parts and accessories from the nearest Edwards company or distributor. When ordering, please state for each part required: 1.
The maximum temperature allowed for warmup setpoint temp is above the alarm limit for the pump so if the temperature is set too high the pump will never warm up. Changing the warm-up temperature does not change the pump’s water cooling operation. This is fixed by Edwards and can only be changed by a downloadable configuration.
A2.10.1 Normal speed The full speed settings for the booster and dry pump are set by Edwards when the pump is manufactured. If a lower full speed is required then this can be set using a downloadable configuration. Configurations can be downloaded using the Edwards Configuration Download Utility (CDU).
The GXS pump has a built in PID pressure control and auto tune feature that can adjust the GXS dry pump speed when the pump is on-process so that the pressure reading of a pressure sensor matches the supplied PID set point. Edwards recommend that the PID is auto tuned after the PID set point is adjusted.
A2.11.2 Using a different gauge It is possible to configure the PID settings so that a different pressure gauge is used as the PID gauge. If an Edwards Active Accessories Module (AAM) is fitted to the pump (available as an accessory, refer to Section 7.3)
A2.13 How to use SIM protocol with a serial port SIM protocol is used as a means of communication between Edwards vacuum pumps and other external control and monitoring equipment. For more information about SIM protocol, refer to the SIM protocol manual P411-00-200.
