CAUTION

WARNING

1Introduction

1.1 Scope of this manual

This manual provides installation, operation and maintenance instructions for the Edwards nXDS series of scroll pump. The pump must be used as specified in this manual. Read this manual before installing and operating the pump.

Important safety information is highlighted as WARNING and CAUTION instructions; these instructions must be obeyed. The use of WARNINGS and CAUTIONS is defined below.

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 process.

Introduction

Pressures are stated as absolute pressures unless otherwise stated. The following warning labels are on the pump:

Warning – refer to accompanying documentation.

Warning – risk of electric shock.

Warning – hot surfaces.

A735-01-880 Issue C

Introduction

1.2 ATEX directive implication

This equipment is designed to meet the requirements of Group II Category 3 equipment in accordance with Directive 94/9/EC of the European Parliament and the Council of 23rd March 1994 on the approximation of the laws of the Member States concerning equipment and protective systems intended for use in potentially explosive atmospheres. (The ATEX Directive).

The ATEX Category 3 applies in respect of potential ignition sources internal to the equipment. An ATEX Category has not been assigned in respect of potential ignition sources on the outside of the equipment as the equipment has not been designed for use where there is an external potentially explosive atmosphere.

There is no potential source of ignition within the pump during normal operation but there may be potential sources of ignition under conditions of foreseeable and rare malfunction as defined in the Directive. Accordingly, although the pump is designed to pump flammable materials and mixtures, operating pr ocedures should ensure that under all normal and reasonably foreseeable conditions, these materials and mixtures are not wi thin explosive limits. Category 3 is considered appropriate for the avoidance of ignition in the case of a rare malfunction which allows flammable materials or mixtures to pass through the pump whilst within their explosive limits.

When flammable materials are present within the equipment:

 Do not allow air to enter the equipment.  Ensure the system is leak tight.

Further details can be obtained by contacting Edwards. Refer to the address page at the back of this instruction manual.

1.3 General description

The nXDS pump is shown in Figure 1. The nXDS pump is a truly dry vacuum pump as all the bearings, with their hydrocarbon lubricant, are isolated from

the vacuum space. The nXDS pump is suitable for use on vapour handling processes, and may be used for some pumping applications involving corrosive substances. For information on pump ing flammable gases, contact Edwards.

The body of the pump includes a fixed scroll and an orbiting scroll. The orbiting scroll is controlled by an electric motor through an eccentric cam on the motor drive shaft. The movement of the orbiting scroll, meshed with the fixed scroll, forms successive crescent shaped volumes in the pump. Gas that enters the pump through the inlet is compressed by the movement of the orbiting scroll and swept towards the centre of the fixed scroll. The compressed gas enters the exhaust port near the centre of the fixed scroll and is exhausted from the pump through the outlet.

Refer to Section 2.1 for details of operating conditions.

1.4 Pump controller

The integral pump controller manages the supply of current to a three-phase electric motor in accordance with operating conditions. The controller monitors power and temperature, and will protect the pump in the event of operation under sustained high load or under fault conditions.

The controller provides the user interface (refer to Figure 1). The pump may be operated in these modes:

 Manually, using the buttons on the interface panel. Refer to Figures 2 and 9.  Remotely via serial communications or d igital and analogue process control (parallel), via the 15-way D-type

logic interface connector. Refer to Section 1.5.

Introduction

1.5 Logic interface

The pump controller can be operated via the 15-way D-type logic interface connector. The signals on the logic interface are of the following types:

 Control inputs: these are switch-type and analogue signals that are used to control the pump  Status outputs: these outputs identify the status of the system Tab

The logic interface has been designed to support both serial contro l, parallel control and monitoring, operating though one connector. For serial control either RS232 or RS485 can be selected.

For Control Modes refer to Table 1. For Logic interface data refer to Section 2.5.

A735-01-880 Issue C

Introduction

1.6 Gas ballast control

To pump high vapour loads, gas ballast can be delivered into the pump to prevent condensati on of the vapour carried by the pumped gases.

Air can be introduced to the low vacuum stages through the gas ballast control (Figure 1, item 3). Alternatively, an inert gas such as nitrogen can be supplied through a suitable external valve and by using the appropriate adaptor, available as an accessory. Refer to Section 7.
