Introduction About this manual Scope of the manual This manual covers the installation, operation and routine maintenance of the MultiExact 4100 Analyzer. It is intended for those already familiar with the installation, use and maintenance of analytical or process instrumentation. The information in this manual is general. Transducer-specific instructions are contained in the relevant appendices at the rear of the manual. A separate manual covers the AquaXact 1688 transmitter in more detail, including theory and performance data. Safety information Read this manual and make sure you fully understand...

Other information provided by the manual Note: Notes give extra information about the equipment. Hints give helpful tips and highlights information which is useful for you to be aware of, for example, specific operating conditions. Product overview The MultiExact 4100 Analyzers are designed to meet the needs of the control and product quality applications of industrial gas producers and users, who require fast, accurate and reliable gas analysis. The analyzer can be fitted with up to four sensors, zirconia, paramagnetic, gas filter correlation (GFX), single beam single wavelength infrared (IR)...

General description The MultiExact 4100 gas analyzer is a chassis into which up to four gas transducer modules may be fitted. The chassis provides power, gas connections and other support functions to the transducers and calculates associated sample gas concentrations. These concentrations are then displayed on the analyzer display screen and may be directed to the analogue outputs and/or the serial output. The analyzer also supports up to eight external analogue input signals. The data from the external inputs may be displayed on the screen, output through the analogue outputs and/or the serial...

Recommended calibration intervals For optimum performance, it is necessary to routinely check the calibration of all the internal gas transducers within the analyzer. The recommended periods for each transducer type are shown in Table 1-1. Gas transducer module High calibration Paramagnetic transducer (purity) Paramagnetic transducer (other) Zirconia transducer Table 1-1: Recommended calibration periods The pressure compensation associated with the purity paramagnetic transducer should also be checked annually (see Appendix G). This manual details the following: • • • • the requirements for and...

Note: When the optional external auto-calibration is configured, a manual calibration adjustment or calibration check will use the auto-calibration valves to select the calibration sample gases as required. Automatic calibration options In the case of external auto-calibration, external customer supplied solenoid valves may be controlled by discrete wiring to relays on the analyser (section 0). The automatic calibration procedure may be started by any of the following: • A trigger from the internal instrument clock An external contact closure A Modbus or PROFIBUS command Product identification...

Connect each transducer outlet to a separate atmospheric vent, free from any back-pressure. Pay particular consideration to the toxicity and asphyxiant nature of the sample gas when selecting a vent location. Flow driven options: Pressure driven options: Do not exceed the rated flow or pressure as transducer damage may result. © Servomex Group Limited 2019

Unpacking Read this manual carefully BEFORE you remove the MultiExact 4100 Gas Analyzer from its shipping container, or you attempt to install, commission or use the equipment. The analyzer is heavy (section 1.2). Take care when handling the instrument. Lift with both hands positioned on either side on the base of the chassis. 1. Remove the analyzer and any other equipment from its packaging. Remove the protective plastic covers from the sample gas inlets and outlets on the rear of the analyzer (Figure 2-1). Figure 2-1: Gas inlets and outlets on rear of the analyzer Hint: If you do not intend...

If you do not intend to use the analyzer immediately: • Refit any protective plastic covers. • Place the analyzer and any other equipment supplied back in its protective packaging. • Store the analyzer as described in section 10.1. Read section 3 – Safety before proceeding. Hint: Keep the shipping documentation and packaging for future use, for example when moving the equipment, or returning it for service or repair. © Servomex Group Limited 20
