CAUTION

WARNING

1Introduction

1.1 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 otherwis e the protection provided by the equipment may be impaired.

Read this manual before installing and operating the dry pumping system. Important safe ty information is highlighted as WARNING and CAUTION instructions; these instructions must be obeyed. The use of WARNINGS and CAUTIONS is defined below.

- he

Warnings are given where failure to observe the instruction could result in injury or death to people.

Cautions are given where failure to observe the instruction could result in damage to the equipment, associated equipment and/or process.

Introduction

The units throughout this manual conform to the SI international system of units of measurement. The following warning labels are on the pump:

Warning - Refer to accompanying documentation.

Warning - Risk of electric shock. Warning - Heavy object.

Warning - Hot surfaces. Protective Earth (ground).

Warning - Moving parts present.

Warning - Maximum angle between paired slings.

M588-00-880 Issue E

Introduction

Warning - Use protective equipment. RF Earth (ground).

The following warnings only appear in this manual:

Warning - Risk of explosion. Warning - Pressurised.

Safety data sheets for chemicals supplied by Edwards can be obtained by contacting Edwards or on www.edwardsvacuum.com.

1.2 Applications

GXS dry pumping systems are suitable for a wide range of industrial applications. Edwards has a dedica ted 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 Edwards.

1.3 Description

The GXS 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 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. 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 / solvent flush kit is available as an option to clean the dry pumping system on ap plications where large quantities of dust and sticky deposits are encountered. The cleaning process is run while the dry pumping system 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.

M588-00-880 Issue E

1.4 Priority of control

The dry pumping system can be controlled by a number of modules: the front control panel (refer to Figure 1), a Pump Display Terminal (PDT) or by the customer’s system through the MCM MicroTIM or one of the ser ial interf aces. Only one of these can have control of the dry pumping system at any one time. That is, once one of these has control of the dry pumping system, control requests from the others are denied. Control must be released by one module before control can be taken by a different module.

There are LEDs to indicate control:

 The LED on the front control panel illuminates when control is taken by the front panel, refer to Figure 1,

item 6.

 The LED on the rear of the pump illuminates when control is taken by the MicroTIM, refer to Figure 3, item 9.  The local control LED on the PDT illuminates when control is taken by that particular PDT, refer to

Appendix A2.

The PDT display also indicates which system is in control.

1.5 Active utility control / standby

Introduction

The Active Utility Control (Green Mode) function may reduce speed, power and purge gas consumption of the dry pumping system while on standby. The dry pumping system can be put into Green Mode / standby mode using the front control panel, the PDT or through the MCM MicroTIM. Refer to Section 4.3 for more information.

All GXS dry pumping systems have a valved cooling system which will cause coolant flow rate to vary in response to pump load conditions. Table 12 states the "minimum flow rate required" under worst case pump load conditions, when all valves are open. Flow rates need t o be increased and/or coolant temperature s reduced if Glycol or other coolants are used dependent on the dilution and type.

† The differential pressure values given are the mi nimum differential pressures required across the wa ter

supply / return at the point of connection to the pump to achieve the desired flow when the solenoid valves are open.

Technical data

Notes: 1. The high flow purge /solvent flush kit is available as an option.

2. The DP clean solvent suction pipe is supplied with the pump but not fitted.

2.8 External evacuation system

Pumpdown performance on dry pumping systems fitted with mechanical boosters can be further enhanced by the use of an External Evacuation System (EES) kit. The EES kit will only provide a performance improvement on pumpdown cycles lasting less than 30s to pressures below 0.1mbar. The EES kit must only be used on clean applications.
