1.1 Introduction
This manual contains information regarding installation and hardware configuration of the
Servomex 4000 series analysers.
A separate Quickstart manual is also supplied with the analyser, reference part number
04000/003D. This details software configuration and operation of the analyser. Extra copies
may be ordered from Servomex.
Details of the hardware and instructions for servicing, by qualified personnel only, are
presented in the 4000 Series Service Manual. This may be ordered from Servomex using part
number 4000002D.
Technical assistance and spare parts are available from Servomex outlets (or their local
agents) listed on the back cover.

1.2 General description
The Servomex 4000 series analyser is a chassis into which up to four gas sensor modules may
be fitted. The chassis provides power, gas connections and other support functions to the
sensors and calculates associated sample gas concentrations. These concentrations are then
displayed on the analyser display screen and may be directed to the analogue outputs and/or
the serial output.
The analyser also supports two external analogue input signals. The data from the external
inputs may be displayed on the screen, output to the analogue outputs and/or the serial output
or accessed using Modbus.
Designed for use in modern industrial and laboratory environments, the analyser is controlled
using an integral microprocessor which provides significant user flexibility.
The 4100 analyser is designed to meet the control and product quality monitoring requirements
of industrial gas producers and users. It can monitor up to four gas streams simultaneously with
independent autocalibration for each stream (provided sufficient extra relays are installed).
The 4200 analyser is intended for monitoring flammable samples, but not those containing
hydrogen or acetylene for which the 4210 must be used. Again, up to four gas streams may be
monitored simultaneously and independent autocalibration can be used with each stream. The
zirconia transducer is not available for these analysers.
The 4900 analyser is a continuous emissions monitoring (CEMs) analyser with a maximum of
four transducers with either one or two sample streams. Independent autocalibration is
available for each stream or transducer (refer to Section 4.6).
None of the above are suitable for use with corrosive samples.
WARNING
The analyser contains no user serviceable parts inside. The instrument enclosure
protects the user from electric shock and other hazards. All servicing should be
referred to qualified personnel.
