Microvision2 Hardware Manual – SP101015.102 August 2010

Overview

The Microvision2 is the latest innovation in RGA technology from MKS Instruments. Designed to meet all the

traditional requirements for an RGA sensor, plus data collection speeds in the milliseconds, even over the

full dynamic range - unachievable with previous technologies.

The Microvision2 is formed around two dedicated processors; an optimized, proprietary processor for data

acquisition and an industry standard CE processor handling external communications via TCP/IP

technology.

Analogue and digital interfaces are provided for integrated systems and future technologies.

Features

Data acquisition through solid state, wide dynamic range, fast settling detector electronics.

Temperature stabilized critical components offering improved signal stability and drift.

Calibrations and configurations stored locally within the RGA.

Flexible I/O capability including a dedicated gauge port.

Further expandability of the I/O capabilities using add-in cards.

TCP/IP and ASCII protocol support

Operation

The Microvision2 is designed to be operated in several ways:

From a host computer – an IBM compatible PC or MAC running the MKS Process Eye Professional or

EasyView software package.

PC or MAC using a web browser such as Internet Explorer or Safari.

Integration into existing systems controlling through the use of the ASCII protocol command set.

This manual focuses on Microvision2 hardware and should be used in conjunction with the relevant user

interface manual during installation.

Any required network communications cards should be installed and configured prior to installing the

Microvision2, or RGA software if supplied.

in a non-hazardous electric stock if touched.

b. Tuning adjustment holes, which are not for operator use.

On the rear panel refers to:

a. Read all instructions carefully before use.

b. The control unit and signal ports are designed for connection to MKS accessories via MKS supplied

cables.

There are no accessible hazardous voltages or currents on these ports.

MKS must be consulted before any non-MKS supplied cables or accessories are connected to these ports.

1.7 Ventilation

The openings in the sides and rear panels must not be obstructed.

Allow a minimum clearance of 50mm all round.

Do not exceed the maximum operating ambient temperature.

Additional Installation Maintenance and Operating Instructions

In order to comply with European regulations, the following procedures must be followed:

A) INSTALLATION

1. The installation procedures given in the operating and technical manuals must be followed in addition to

these instructions.

2. The mains power cable must conform to local regulations and must have a protective earth (PE)

conductor securely connected to the power plug protective earth contact.

3. The short earthing braid supplied with some products, must be fitted between the terminal on the RF

head and one of the CF40 vacuum flange bolts.

4. Only cables supplied with the equipment may be used for interconnections. If extension cables are

required to obtain a greater separation between control unit and RF head, or if longer serial

communications cables are required, they must be supplied by MKS Instruments Ltd.

5. Cables attached to all other ancillary signal and control ports must have a length of less than 3 meters. If

greater length is required, MKS Instruments Ltd. must be contacted for technical guidance on possible

EMC and safety issues.

6. The vacuum system on which the analyser/RF head is mounted must be earthed, to a protective earth,

preferably to the same protective earth as the control unit.

B) OPERATION

1. The equipment is not authorised for use as a critical component in a life support or safety critical system

without the express written approval of MKS Instruments Ltd.

2. All instructions given in the operating manual must be followed.

3. Adjustments are strictly limited to those accessible from the control panel and computer keyboard and

only when running software supplied by MKS Instruments Ltd.

WARNING-DANGEROUS VOLTAGES EXIST INSIDE THE

EQUIPMENT

1. Maintenance functions must only be carried out by competent persons.

2. During the warranty period, faulty equipment must be returned to MKS Instruments, Spectra Products

Ltd., unless special arrangements are made.

3. There are no user serviceable parts in the electronic equipment. Certain components are EMC and

safety critical and must not be substituted. Replacement parts are available from MKS Instruments UK Ltd.

4. Equipment enclosures embody certain special fastenings and bonding devices that affect EMC and

safety performance. These must be correctly re-fitted after servicing.
