3 Introduction
3.1 The DGA 2500
The SUN® DGA 2500 is a versatile, high-performance PC-based test instrument for the analysis of motor vehicle exhaust gases. The unit is designed to meet the performance requirements of OIML Class 1 and 0 and ISO 3930.
The basic configuration of the unit comprises:
-A gas analysis module containing a Siemens “Sibench” gas bench.
-A rpm/oil temperature module (ROTI) for the measurement of engine speed and oil temperature. The unit is supplied with a Grey inductive pick-up (P/N EAX0048E03A; for use with conventional HT ignition systems) as standard equipment.
-An exhaust probe and hose assembly, used for the collection of the gas sample from the vehicle tailpipe.
The DGA 2500 forms part of the SUN® Diagnostic Platform System. Refer to the SUN® Diagnostic Platform Operator’s Manual (2: ‘The SUN Diagnostic Platform’) for an introduction to the system as a whole.
The addition of an optional USB to 4 x RS232 connector enables a smoke module, for testing diesel emissions, and a Portable Data Link, used to obtain information from the vehicle engine management system, to be connected to the system via the Gas Analyser. This connector can also be used for external communication with, for example, the customer’s central computer system.
Specific software versions will be available for performing the emissions tests specified by separate national or international jurisdictions. Although this jurisdiction specific software may alter the DGA 2500 standard software described herein, this manual is also applicable to these specific programs when used in conjunction with the specific documentation relating to such programs.

INTRODUCTION |
With the standard software the unit is capable of measuring the concentrations of up to five gases in vehicle exhaust emissions:
-Carbon Monoxide, Carbon Dioxide and Hydrocarbons (CO, CO2 and HC) by infra red absorption.
-Oxygen (O2) by an operator changeable electrochemical cell.
-Oxides of Nitrogen (NO) by electrochemical cell. The NO cell is optional and is NOT operator changeable.
In addition to the gas measurements the unit also displays:
-Lambda (λ) according to Brettschneider.
-Engine speed (rpm) via the ROTI module. An inductive rpm pickup, to be placed on a secondary ignition cable, is supplied as standard equipment. A capacitive pick-up, for use on a primary or injector wire, and a primary ECU/RPM adapter, for connection to a square wave from the engine management system, are available as options, thus making the analyser suitable for conventional, wasted spark and direct ignition systems.
-Oil temperature via the ROTI module by means of an oil temperature probe substituted for the oil dipstick.
Note:
pIn cases where a Portable Data Link is connected to the analyser, rpm and oil temperature data will be obtained via the PDL.
CO corrigé (COc) may be displayed using a formula corrected for fuel type.
3.2 Maintenance
Details of the maintenance operations that should be carried out by the operator are included in this manual together with a list of operator service messages and a list of maintenance parts.
All maintenance operations, other than those specifically described in this manual, must be carried out by trained service personnel authorised by the manufacturer.
In particular, full gas calibrations must only be performed by a qualified representative of the manufacturer.

.
Figure 5-1 The Gas Analyser Menu
•To access the Gas Analyser Menu , select the “Gas Analyser” option from The Diagnostic Platform Main Menu (see the SUN® Diagnostic Platform Operator’s Manual 5.1: ‘The Diagnostic Platform Main Menu’).
The following options may be selected:
-Free Measurement Procedure.
-SUN EEC Test Procedure.
-The Gas Analyser System Setup Menu.
Note:
pIf the DGA 2500 is configured to perform a country specific test procedure, the SUN EEC test procedure will not be available. In this case the “SUN EEC Test” button will be replaced by an icon button corresponding to the country specific test in question.
• The “Free Measurement” procedure.
The Free Measurement procedure continuously measures and displays the values for all available test parameters. Upper and lower limits for any or all of these parameters may be introduced as required. Refer to 8: ‘Operation – The Free Measurement Procedure’for further information.
• The “SUN EEC Test” procedure.

GAS ANALYSER MENU
The SUN EEC Procedure is based on the provisions of EU directives which specify a procedure to be followed in testing motor vehicle emissions and prescribes maximum default values for certain gas emissions and related parameters. Refer to 9: ‘Operation – The SUN EEC Test Procedure’.
• The “System Setup” option.
The The Gas Analyser System Menu allows operator maintenance functions to be initiated, gas analyser system settings to be made, gas analyser system information to be consulted and updates to the gas analyser software to be loaded. Refer to 5.2: ‘The Gas Analyser System Menu’ for further information.
•To return to the The Diagnostic Platform Main Menu, press the “Home” icon button on the toolbar.
•To place the Gas Analyser in Standby Mode, press the “Standby” icon button on the toolbar.
Once the Gas Analyser is switched on, it should remain on for the whole working day, however, it is recommended that the unit should be put into Standby Mode when tests are not being performed. This will reduce waer and tear to the pump and increase the effecive life of the filters.
The unit will return to the normal operating mode when:
-The “Standby” button is pressed once more, or
-One of the Gas Analyser Main Menu option buttons (“Free Measurement”, “SUN EEC Test” “Country Specific Test”, or “System Setup”) is pressed.
On leaving the Standby Mode, a Zero-calibration (see 6.2.4) and HC Residue Check (see 6.4) will automatically be performed before the unit returns to normal operation.
