Introduction; Scope And Definitions; Applications; Description - Edwards GXS Series Instruction Manual

1. Introduction

1.1 Scope and definitions

This manual provides the installation, operation and maintenance instructions for the
GXS dry pumping system. The pump must be used as specified in this manual. Read this
manual before the installation and operation of the pump.
The units used throughout this manual conform to the SI international system of units of
measurement.
The safety Data Sheets for the chemicals supplied by us can be obtained by contacting
us, or at www.edwardsvacuum.com.

1.2 Applications

The GXS dry pumping systems are suitable for a wide range of industrial applications. We
have a dedicated team of applications engineers who can help to determine the best dry
pumping system for an application.
Warranties may be invalidated if the dry pumping system is used on an unsuitable
application. If in doubt, contact us.

1.3 Description

The dry pumping systems range has been developed to meet the demanding
requirements for process pumping solutions in industrial applications. The range sets
new standards for harsh process capability, reliability and reduced cost of ownership in
low footprint packages.
There are different ways to control the dry pumping system and monitor status. The user
can manually press the controls on the front panel and monitor the LEDs on the front
and rear of the dry pumping system. The Pump Display Terminal (PDT) gives further
functionality for set up and status monitoring. Alternatively the dry pumping system can
be controlled using a distributed control system by connecting to the parallel interface
by the MCM MicroTIM. There are also several serial interface options, including Ethernet
connection.
A high flow purge and solvent flush kit is available as a factory‑fit option to clean the
pump mechanism on an applications where large quantities of dust and sticky deposits
are encountered. The cleaning process is run while the pump is in Green mode/Standby
mode and is carried out without the need to remove the pump enclosure. A PDT is
required to initiate the cleaning process, it controls a set sequence called DP Clean.

1.4 Priority of control

The dry pumping system can be controlled by a number of modules:
▪ Front control panel (refer to
▪ Pump Display Terminal (PDT)
▪ Customer's system through the MCM MicroTIM or
▪ One of the serial interfaces.
