Introduction

1.1 10BAbout this Manual

This manual contains the data and instructions for the installation, operation, and

maintenance of the gas sampling board with the sampling probe of the G4100

NOX/O2Analyzing System.

The G4100 NOX/O2Analyzing System consists of two parts:

G41 NOX/O2Analyzer

G4100NOX/O2gas sampling board with the sampling probe

The instructions for installation, operation, and maintenance of the analyzers are

provided in the separate manual – the G41 NOx/O2 Analyzer manual (p# 01250 or

01819).

For the installation, operation, and maintenance of the G4100 NOX/O2Analyzing

System, both manuals must be read carefully in their entirety.

The manual has been made in general terms and do not take into consideration a

specific installation. As such, the instruction manual is designed for the standard

sampling system fitting with the G41 NOX/O2Analyzer.

The manual does not describe all possible situations but only the most common

and known situations, and cannot replace the necessary instruction and education

of the personnel.

Should situations not described in the manual occur, which cannot be solved in

accordance with normal known practice and good workmanship, the operator

should contact Green Instruments A/S for instructions.

This manual does not claim to cover all details or variations in equipment or to

provide for every possible contingency that may arise during installation, opera-

tion, or maintenance.

System Installation

Read this chapter in its entirety before installing the system.

3.1 Control at Delivery

When you receive the G4100 NOX/O2Analyzing System, please inspect and con-

firm that the received items are in accordance with the packing list and not dam-

aged. Any discrepancy should be reported to the supplier immediately. If any of

the received parts are damaged, the shipping company should be informed and

new parts should be made available before completing the installation.

3.2 Where to Install the System

Satisfactory operation, faultless functions, and minimal maintenance of the G4100

NOX/O2 Analyzing System are achieved by paying attention to the following

points:

Make sure to install the ejector probe in a suitable location where it will extract

the gas that is going to be tested.

The ejector probe shall be fitted at least 10 pipe diameters after the outlet of the

engine, the turbocharger, or the last after-treatment device – choose whichever

is further downstream. However, the ejector probe shall also be placed at least

0.5 m or 3 pipe diameters upstream from the exit of the exhaust gas system –

choose what provides the greatest length. See 107H25H25HFigure 3-1 for the installation

layout of the ejector probe. If you find it difficult estimating where to install the

ejector probe, please contact Green Instruments A/S for more instructions.

As a standard scope of supply, the analyzing board can be installed up to 3 m

from the ejector probe. If necessary, the umbilical cord can be extended.

G4100 NOx/O2 Analyzing System

The analyzing board shall be placed and installed where the ambient tempera-

ture is below 55 °C at any time.

The system shall be installed in a clean place away from dust, oil mist, and

moisture. The elements of the system shall be installed at viewing level so that

it is easy accessible in connection with operation and service.

3.3 Safety Aspects

Warning

Make sure to follow the operating instructions!

Read the manual before operating and servicing the system.

Hot sensor/probe!

The sensor/probe is hot and can cause severe burning of personnel if not handled

with care.

Installation and operation!

It should be pointed out that installation and operation of the G4100 NOX/O2Ana-

lyzing System and associated equipment must be carried out by skilled, trained,

and certified personnel, and that Green Instruments A/S does not take any respon-

sibility for the operation of the system and associated equipment whatsoever. The

successful and safe operation of this equipment is dependent upon proper han-

dling, installation, operation, and maintenance.

Recycling!

Please do not dispose the G4100 NOX/O2Analyzing System with regular refuse.

Disposal should be in accordance with the requirements of the current statutory

regulations.

3.4 Ejector Probe

The ejector probe is supplied with a mounting socket, gasket, sample tube, con-

nection for ejector air, connection for test gas and back-flushing air, sensor, and

housing with mounting plate.

The ejector probe has a small air operated ejector, which will propel the sample

gas into the sensor and back into the stack. The sample gas flow is drawn through

the sample filter element into the sensor area via a narrow passage securing quick

response time. The sample gas velocity and responding time is controlled by the

flow of the ejector air.

System Installation

The gas, which passes the ejector probe, must represent the gas to be tested. Holes

and leaks in the gas ducting system before and after the probe may influence the

accuracy of the measurement.

The ejector probe shall be placed so that it is protected against mechanical dam-

age. The flue gas temperature cannot exceed the given temperature limit of the

ejector probe.

When welding the mounting socket to the stack, make sure that the mounting

plate of the ejector probe is mounted with the sampling hose connection facing

down and the ejector probe protection house mounted in a vertical position of the

stack. The insert length of the ejector probe (250-300 mm) should be greater than

10 % of the duct diameter. See 26H26HFigure 3-1 for the installation layout of the ejector

probe.

Exhaust Duct

Distance to the next upstream bent:

min. 3 duct diameters

Distance to the engine/turbo charger:
