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)
an active gauge can be connected to it and used the same as a PID gauge.
1. Fit the gauge to an appropriate port on your system.
2. Connect the gauge to the Active Accessories Module.
3. From the Fit accessory menu select Active gauge to Fitted.
4. From the Setup menu select Set sequences.
5. From the Sequences menu, select PID....
6. From the PID menu, select PID gauge...
7. From the PID gauge menu, select Active gauge.
A pressure gauge can also be used that has a 4 - 20 mA signal output. To use a gauge of this type a GXS pressure input
cable (4 - 20 mA) and associated connector kit will need to be purchased which are available as accessories, refer to
Section 7.3.
1. Fit the GXS pressure input cable accessory following the instructions given in the installation manual supplied
with the accessory.
2. Fit the connector kit onto the cable on the pressure gauge.
3. Connect the gauge to the pressure input connection on the rear of the GXS (Figure 3, item 14)
4. From the Fit accessory menu select Pressure to Fitted.
5. From the Setup menu select Set sequences.
6. From the Set sequences menu, select PID...
7. From the PID gauge menu, select Pressure (4 - 20mA).
A2.11.3 Set pump into Green Mode mode
1. Start the GXS dry pump using the PDT and let it warm up.
2. Check on the Status display that there is a pressure reading for “AG x.xxExx mbar” and that the reading is what
you expect for the chamber.
3. Set the GXS into Green Mode mode using the Commands menu option.
A2.11.4 Enable PID
1. From the Setup menu select Set sequences.
2. From the Sequences menu select PID.
3. From the PID menu select enable/disable and then set PID to enabled.
