1 Introduction
The AWS2 signal conditioning unit is used in conjunction with the RobertBosch LSU broadband lambda sensor to evaluate the sensor signal.
The AWS2 signal conditioning unit can be used for the following as aninexpensive alternative to the precision measuring instrument LA4:
� evaluating the LSU sensor signal in engine ECUs
� continuous measurements to determine sensor accuracy
� map optimization.
The LSU sensor is fitted in the exhaust system as a measuring sensor (possiblyin addition to a lambda sensor which has already been installed). The signalconditioning unit AWS2 is used to determine the pump current of the sensorand the current sensor internal resistance.
The signal conditioning unit can be operated with various model ranges of theLSU lambda sensor; different sensor internal resistances must be set on theunit for this purpose. The unit is also designed to facilitate upgrading to ensurethat it can be used with all future model ranges.
1.1 About This Manual

2 Startup
This section explains how to install the LSU lambda sensor, start up the AWS2and describes the relevant settings for the sensor heater.
Please note that improper handling can lead to the lambda sensor and theAWS2 being damaged.
2.1 Installing the LSU Lambda Sensor
You can obtain the LSU lambda sensor from Robert Bosch GmbH or order itdirectly from ETAS GmbH.
Please observe the following general guidelines when installing the lambdasensor:
� Select the point of installation in exhaust gas pipes at a point where the exhaust gas composition is representative and remains within the prescribed temperature limits.
The following maximum values apply for the LSU 4.2 you can obtain from ETAS:
� max. gas temperature: 980 °C
� max. temperature at the hexagon head: 630 °C
Cold exhaust gas at a high flow velocity may exceed the operating temperature of the sensor cell, depending on the operating voltage. This may lead to measurement errors.
Hot exhaust gas at temperatures above the controlled ceramic temperature may cause the operating temperature of the sensor cell to rise. This may lead to measurement errors.
� The active sensor ceramic is heated up quickly by the internal heater. When defining the point of installation, make sure that the amount of condensate penetrating from the exhaust gas system is minimal in order to avoid ceramic breakages.
The sensor should be installed at a position which fulfils the following conditions:
� Define a point for installing the sensor as close to the engine as possible. Ensure a minimum distance of 15 cm from the combustion chamber.
� Strive to achieve a rapid warm-up of the exhaust pipe just upstream of the sensor installation point.

AWS.book Seite 8 Mittwoch, 18. April 2007 10:00 10
� The exhaust pipe should be on a downward stretch to avoid the accumulation of condensate upstream of the sensor installation point (no recesses, projections or cutting edges, etc.).
� The angle of installation should be inclined at least 10° to the horizontal (sensor tip pointing down).
This prevents condensate or fuel from accumulating between the sensor housing and the sensor ceramic during the cold-start phase.
� Installation using special grease on screw thread (e.g. Bosch No. 5 966 478 112 for the 120 g tin).
� Tightening torque: 50 - 60 Nm, the material and the thread must have sufficient properties and strength.
� Avoid excessive heating of the sensor cable gland, in particular when the engine is switched off.
� Do not use any cleaning or greasy liquids or vaporizing substances on the sensor connection.
Startup
AWS.book Seite 9 Mittwoch, 18. April 2007 10:00 10
How to install the LSU lambda sensor
� Select a position on the exhaust pipe for the lambda sensor at least 15 cm from the combustion chamber.
Otherwise, the sensor will suffer heat damage.
� Before installing the sensor, weld a threaded boss in the exhaust manifold.
� When you install the LSU lambda sensor, pay attention to the use of ultra-high heat-resistant lubricant (cf. page 8). Spread it round the threaded boss of the LSU sensor before you screw the sensor in.
This will avoid difficulties when you remove the sensor later.
� The tip of the LSU lambda sensor should project at least half way into the exhaust pipe to obtain accurate mixture measurements.
The LSU lambda sensor is heated via the AWS2 and must always be connected to the AWS2 when it is exposed to engine exhaust gases.

2.2 Starting Up the AWS2 Signal Conditioning Unit
This section describes how to start up the AWS2 signal conditioning unit. Ittells you how to connect the unit and which settings you have to adjust beforeyou can switch it on.
Starting up takes place in three steps which are all described in detail below:
� setting the heater control
� setting the sensor internal resistance
� connecting the lambda sensor
2.2.1 Setting the Heater Control
The AWS2 controls the heater by default; the heater release on the front of theunit is bridged (EN and GND connected to each other).
This setting can be kept for cold-start measurements and for cases where nosuitable ECU is available.
If you are using the AWS2 on board and a corresponding engine ECU isinstalled, connect the heater control to the ECU. This means you are linking thetemperature of the sensor to the temperature of the exhaust gas flow, andthus minimizing the risk of damaging the sensor.
To connect the heater control to the engine ECU, you need details of the ECUpin assignment, which you can find out if necessary from the manufacturer.
Connecting the heater control
� Remove the shoprting bar that connects the EN and GND terminals on the front of the unit.
� Connect the AWS2 GND terminal to the electronic ground of the ECU.
Always use the electronic ground to prevent the heater control from being damaged due to ground offset.
Startup
AWS.book Seite 11 Mittwoch, 18. April 2007 10:00 10
� Connect the AWS2 EN terminal to the "Engine on" signal of the ECU.
The sensor is heated as soon as the engine is switched on. The yellow LED indicates that the sensor is being heated.
2.2.2 Setting the Sensor Internal Resistance
The AWS2 signal conditioning unit can be operated with various model rangesof the LSU lambda sensor. There is a characteristic sensor internal resistance forevery model range.
Make sure that the unit is set correctly before you connect the sensor to theAWS2. If you are not sure which model range your sensor belongs to, ask themanufacturer about the internal resistance.
Please refer to the following table for information on the sensor internalresistance (Ri) and the ordering description of the most common model ranges.

Setting the sensor internal resistances
� Use the table Tab. 2-1 to determine the nominal internal resistance of your lambda sensor. If you are in any doubt, contact the manufacturer for the precise value.
� Use the rotary switch on the back of the unit to set the appropriate value.
2.2.3 Connecting the Lambda Sensor
The last step is to connect the lambda sensor to the AWS2 using the cablesupplied and activate the power supply.
The AWS2 is operated with 12 V DC which is required for signal evaluation andthe heater control.
Connecting the lambda sensor
� Connect the cable supplied to the 26-pin socket on the back of the AWS2.
� Connect the general-purpose connector on the sensor cable to the corresponding jack on the cable.
Do not use any cleaning or greasy liquids on the sensor cable connection.

3 Working with AWS2
The terminals for the output signals of the AWS2 are on the front of theinstrument and are shown with the names of the output signal:
� VIp � lambda sensor pump current
� VRi � lambda sensor internal resistance
You can use the sensor pump current to determine the lambda value with thehelp of a suitable curve: the sensor internal resistance is the basis forcalculating the current sensor temperature.
A voltage is available at the two outputs of the AWS2 which linearly dependson the relevant measurement, i.e. the sensor pump current or its internalresistance.
The values for the output voltage can be read using a simple measuringinstrument or oscilloscope. If you are using an ECU in which suitable inputs aredefined, you can connect these directly to the output signals of the AWS2.
The following sections describe how you execute simple measurements withthe AWS2 and evaluate the output signals of the AWS2.
Please refer to page 24 in the Appendix of this manual for an overview of thelambda curves for the common model ranges.
3.1 Lambda Measurements
Lambda measurements can be executed as continuous measurements tocheck the accuracy of the sensor or as measurements in the vehicle. In bothcases, the AWS2 output signal VIp is used to determine the sensor pumpcurrent.
An ECU is not normally used for continuous measurements; the heater releaseon the AWS2 has to be bridged.
When lambda is measured in the vehicle, the heater release should beconnected to a suitable engine ECU (cf. the section "Setting the HeaterControl" on page 10). A suitable curve must be available on the ECU if youwant to use the output signal of the AWS2 there. The output signal is allocatedto the lambda air/fuel ratio in the ECU.
The evaluation of the pump current signal VIp is described in the next section.
3.1.1 The Pump Current Ip
The pump current Ip of the LSU lambda sensor is the basis for determining thelambda value in the exhaust gas flow. The lambda value is calculated in twosteps:
Working with AWS2 15
16
AWS.book Seite 16 Mittwoch, 18. April 2007 10:00 10
� first of all, the sensor pump current Ip is derived from the output signal VIp
� you then use the suitable curve for your sensor to determine the lambda value.
The following formula shows the relation between the output signal VIp andthe pump current Ip.
This results, for example, in a pump current Ip of about 1.0 mA for the valueVIp = 4.15 V.
For further interpretation of the measurement, use a curve suitable for thesensor used to determine the lambda value which corresponds to the pumpcurrent Ip.
Fig. 3-1 shows the relationship between the pump current Ip and the lambdaair/fuel ratio (here using the example of the LSU 4.2 model range which can beobtained from ETAS at 100 Ω).
Fig. 3-1 Lambda Curve for the LSU 4.2 Model Range at 100 Ω
When using the LSU 4.2 model range at 100 Ω, the calculated pump currentIp = 1 mA corresponds to a lambda value of about 1.7. The exhaust gas is lean.For ideal combustion (lambda value = 1), the pump current has to be Ip -0.0304 which approximately corresponds to an output voltage VIp of 2.5 V.
The lambda curves for the common model ranges are listed in the Appendix tothis User�s Guide on page 24. The diskette supplied also contains the curves inCSV file format.

3.2 Measuring the Sensor Temperature
In addition to determining the lambda value, you can also determine thecurrent internal resistance of the sensor both in continuous measurements andmeasurements in the vehicle to monitor the measuring accuracy.
You use the VRi output of the AWS2 (whose signal you can read using asuitable measuring instrument) to determine the sensor internal resistance.
The evaluation of the output signal VRi is described in the following section.
3.2.1 The Sensor Internal Resistance Ri
The sensor internal resistance Ri makes it possible to determine the currentsensor temperature. The sensor only returns reliable results if it has attained asuitable operating temperature. This is why you still you have to preheat thesensor (for about 20 seconds) when executing, for example, cold-startmeasurements.
The relation between the output signal of the AWS2 VRi and the internalresistance of the sensor depends directly on the model range used. Thefollowing formula describes the general relation.
The basis for the allocation of the values is the nominal sensor internalresistance Ri nom. You determine the relevant slope α for the equation above inaccordance with the internal resistance from the following table.
This means that the following formula is valid for the LSU 4.2 model rangewith an internal resistance of 100 Ω.
Model Range Ordering Description Ri nom. Slope α
LSU 4.2 0 258 007 0320 258 007 071
100 Ω 3,29 mV / Ω
LSU 4.2 0 258 007 � (other) 80 Ω 2,63 mV / Ω
LSU 4.7 0 258 007 016 100 Ω 2,63 mV / Ω

AWS.book Seite 18 Mittwoch, 18. April 2007 10:00 10
A general rule for the interpretation of the output signal is: the higher thevoltage VRi, the higher the sensor temperature. You have to ascertain the curvefor the sensors with which you determine the relation between internalresistance and sensor temperature yourself.
