2 Hardware Description
2.1 Overview
2.1.1 Products and Application Areas
The Smart Lambda Sensor Cables CBS100.1-2, CBS104.1-2 and CBS105.1-2
convert the signal of a Bosch LSU4.9 broadband lambda sensor into an analog
output signal. The three Smart Lambda Sensor Cables of this product family
were developed for different applications.
The electronics for measuring the oxygen content or the lambda value and for
controlling the sensor heater is integrated in the cable so that the LSU4.9
lambda sensor together with the Smart Lambda Sensor Cable and a power
supply is ready for immediate use.
Fig. 2-1CBS10x.1-2 Smart Lambda Sensor Cable
The CBS10x.1-2 Smart Lambda Sensor Cable is fitted with an RB150 plug for
connecting the LSU4.9 sensor. The signal, diagnostic and configuration lines at
the other end of the cable are fitted with ferrules and can easily be configured
with specific plugs of the customer.
TIP
Unless otherwise indicated, the descriptions, properties and technical data in
this manual apply to all variants of the Smart Lambda Sensor Cable
(CBS100.1-2, CBS104.1-2 and CBS105.1-2). In these generally applicable text
segments, the common short name "CBS10x.1-2" is being used.
TIP
The CBS10x.1-2 Smart Lambda Sensor Cables feature an identical mechani-
cal design, except for the number of connecting lines.

ETAS Hardware Description
CBS10x.1-2 - User’s Guide 12
CBS100.1-2 and CBS105.1-2
If the Smart Lambda Sensor Cables CBS100.1-2 and CBS105.1-2 are supplied
with DC voltage, it can be configured whether the output signal is a function
either of the oxygen content or the lambda value of the gas or the pump current
of the sensor.
CBS104.1-2
Together with an LSU4.9 lambda sensor, the CBS104.1-2 Smart Lambda Sen-
sor Cable emulates an LSM11 discrete-level sensor. With connected LSU4.9
lambda sensor, the signal of an LSM11 discrete-level sensor in the range of -
20 mV to +80 mV is exactly replicated by the analog signal at the cable output.
In the process, the emulation of the LSM11 discrete-level sensor with the
LSU4.9 broadband sensor supplies significantly more reliable measuring
results on the lean scale than the original LSM11 discrete-level sensor. LSM11
discrete-level sensors in use can simply be replaced electrically and mechani-
cally with an LSU4.9 broadband sensor and a CBS104.1-2 cable.
2.1.2 Properties
Properties of the CBS10x.1-2 Smart Lambda Sensor Cables:
• Integrated control of the heater of the lambda sensor
• Galvanic isolation of analog output from the supply voltage
• Selectable measure variable (CBS100.1-2 and CBS105.1-2; only with
supply of DC voltage)
Output signal and measure variables

Diagnostic circuit
A diagnostic circuit of the CBS10x.1-2 Smart Lambda Sensor Cable continu-
ously checks the stability of the internal control circuits, the correct function of
the connected sensor and the cable connections to the sensor. An error case is
signaled at the "ERROR" connection.
Electrical isolation
The analog output (AOUT, AOUT_GND) is electrically isolated from the supply
voltage (AC1, AC2) for all cable variants.
The connections "CONFIG" (configuration input) and "ERROR" (error output) of
the Smart Lambda Sensor Cables are electrically isolated from the "AOUT" con-
nection (analog output): the configuration input and error output are not on the
potential of the output signal, but on the potential of the supply voltage.
2.2.3 Inputs and Outputs (Open Cable End)
The signal, diagnostic and configuration lines at the open end of the CBS10x.1-
2 Smart Lambda Sensor Cable (part 3 in Fig. 2-2 on page 13) are connected to
the power supply and the inputs and outputs of the application circuit. Depend-
ing on the cable type, the following signals are available at the lines fitted with
ferrules:
The mapping of the signals to the connections is located in chapter 4.2.4
on page 27.
2.2.4 Connections "AOUT" and "AOUT_GND"
CBS100.1-2 and CBS104.1-2
The "AOUT" connection of the Smart Lambda Sensor Cables CBS100.1-2 and
CBS104.1-2 is a voltage output.
CBS105.1-2
The "AOUT" connection of the CBS105.1-2 Smart Lambda Sensor Cable is a
passive current output (4 to 20 mA).

Fig. 2-3Connecting the CBS105.1-2 Smart Lambda Sensor Cable
The CBS105.1-2 Smart Lambda Sensor Cable must be connected as passive 2-
wire measuring transformer with additional voltage supply for the current inter-
face (see Fig. 2-3 on page 15). An additional external power supply or a voltage
supplied by the PLC can be used for the voltage supply of the current interface
(loop supply) of the Smart Lambda Sensor Cable.
2.2.4.1 Output signals and measure variables
Supply with DC voltage
If the Smart Lambda Sensor Cables CBS100.1-2 and CBS105.1-2 are supplied
with DC voltage, the wiring of the "CONFIG" connection allows selecting to
which measure variable the signal issued at the "AOUT" connection is assigned
(see chapter 4.3.4 on page 29).
TIP
Operating the current interface ("AOUT" output) of the CBS105.1-2 Smart
Lambda Sensor Cable requires an additional voltage supply. The current
interface is not supplied via the voltage supply of the Smart Lambda Sensor
Cable (connections "AC1" and "AC2"!

Supply with AC voltage
If the Smart Lambda Sensor Cables CBS100.1-2 or CBS105.1-2 are supplied
with AC voltage, the oxygen content is issued as measure variable at the
"AOUT" connection. The measure variables lambda and pump current cannot
be selected in the operating mode.
2.2.5 "CONFIG" Connection (Configuration Input)
If the Smart Lambda Sensor Cables CBS100.1-2 and CBS105.1-2 are supplied
with DC voltage, wiring the "CONFIG" connection allows selecting whether the
output signal is a function either of the oxygen content or of the lambda value
of the gas or the pump current of the sensor (see chapter 4.3.4 on page 29).
2.2.6 "ERROR" Connection (Error Output)
The CBS10x.1-2 Smart Lambda Sensor Cables signal an error case at the
"ERROR" connection with a voltage of approx. 4 V to ground. As soon as the
error condition no longer exists, it is switched back to normal operation.

TIP
A voltage corresponding to the behavior of an LSM11 discrete-level sensor is
always output at the "AOUT" connection of the CBS104.1-2 Smart Lambda
Sensor Cable.

When supplying the CBS10x.1-2 Smart Lambda Sensor Cables with AC volt-
age, the connections "CONFIG" and "ERROR" are without function.

CBS10x.1-2 - User’s Guide 17
To signal an error state in the application circuit, an optocoupler, an LED or a
programmable logic controller (PLC) can be connected directly to the "ERROR"
error output .
Signaled error states
• As long as the sensor temperature is still below approx. 750 °C (rated:
780 °C) during the warm-up phase.
• If the AC1/AC2 supply voltage falls outside the allowed range.
• If the sensor is being cooled off too much or heated up further due to
external exhaust gas temperatures or the exhaust gas volume flow:
Tsensor < 750 °C or Tsensor > 800 °C
• If a short circuit of the sensor signals to the positive or negative supply
voltage occurs in the sensor or in the cable harness to the sensor or if a
line interruption occurs in the cable harness to the sensor.
2.2.7 Connections "AC1" and "AC2" (Voltage Supply)
The Smart Lambda Sensor Cables of the CBS10x.1-2 product family can be
supplied with a DC or AC voltage.
The electronics for the sensor heater is integrated in the cable so that the
LSU4.9 lambda sensor together with the Smart Lambda Sensor Cable is sup-
plied by a common power supply.
Switching on the power supply
The supply voltage of the CBS10x.1-2 Smart Lambda Sensor Cables must be
supplied via a switching process.
The power supply of the CBS105.1-2 Smart Lambda Sensor Cable and the
external power supply for feeding the current interface can be switched on in a
random order.
TIP
Contrary to the industry standard (current interface 4 to 20 mA), the
CBS105.1-2 Smart Lambda Sensor Cable does not supply an increased cur-
rent signal at the "AOUT" output in case of an error. An error case is signaled
at the "ERROR" connection.
TIP
Operating the current interface ("AOUT" output) of the CBS105.1-2 Smart
Lambda Sensor Cable requires an additional voltage supply. The current
interface is not supplied via the voltage supply of the Smart Lambda Sensor
Cable (connections "AC1" and "AC2")!

3.1 General Recommendations for Installation and Opera-
tion
3.1.1 Lambda Sensor Cable
Assembly location
Fastening with cable ties
Opening the electronic module
CAUTION
Damage or destruction of the Smart Lambda Sensor Cable is possible.
The Smart Lambda Sensor Cable is approved only for the assembly and oper-
ation on components or at locations that ensure that the technical data of the
cable (see chapter 4 on page 25) are being maintained during operation.
CAUTION
Damage to the housing is possible!
Cable ties for fastening the Smart Lambda Sensor Cable may be attached
only to the infeed lines of the cable. Fastening on the electronic module
(housing) of the cable is not allowed.
CAUTION
Loss of the function is possible!
Do not open the electronic module (housing) of the lambda sensor cable! A
safe function in the re-closed state cannot be guaranteed.

3.1.2 Lambda Sensor
With improper handling, the lambda sensor can deteriorate prematurely or be
damaged.
Deteriorated or defective lambda sensors
Deteriorated or defective lambda sensors must be replaced with a new unit. De-
energize the Smart Lambda Sensor Cable before replacing the lambda sensor.
3.2 Startup Sequence
Sequence for the startup of the Smart Lambda Sensor Cable:
A Install LSU4.9 lambda sensor in the exhaust-gas routing (see chapter 3.3
on page 19)
B The connections of the CBS10x.1-2 Smart Lambda Sensor Cable can be
cabled in any order (see chapter 3.4 on page 22).
3.3 Assembly of the Lambda Sensor
3.3.1 Technical Information
CAUTION
If the sensor heater is missing, it could lead to premature deterioration or
damage of the lambda sensor.
The lambda sensor must be supplied with current at all times as soon as it is
exposed to the exhaust gases of a combustion process.
If the CBS10x.1-2 cable is connected with a voltage supply, the required con-
trolled sensor heater voltage is provided at the sensor connection.
NOTICE
Each lambda sensor is individually trimmed via a resistor in the plug of the
lambda sensor. For this reason, the plug of the lambda sensor may not be
removed.
TIP
Observe the general recommendations for installing and operating the Smart
Lambda Sensor Cable and the lambda sensor in chapter 3.1 on page 18!
TIP
Additional information about the Bosch lambda sensors are located in the
document "Bosch: Technical Customer Information for LSU4.9" (Y 258 K01
008-000).

3.3.2 Notes about Installing the Lambda Sensor
The following general guidelines should be taken into consideration when
installing the LSU lambda sensor:
• Select the installation location in exhaust-gas lines so that a representa-
tive exhaust gas composition is ensured while maintaining the specified
temperature limits.
The following maximum values apply to the LSU4.9 lambda sensor:
– Maximum gas temperature: 930 °C
– Maximum hexagon temperature: 570 °C
Depending on the operating voltage, cold exhaust gas in conjunction
with high rate of flow can cause the operating temperature of the sensor
cell to fluctuate. This can lead to measurement errors.
Hot exhaust gas with temperatures above the regulated ceramic tem-
perature can cause the operating temperature of the sensor cell to
increase. This can also lead to measurement errors.
• The active sensor ceramics is quickly heated up by the internal heater.
The installation location must be selected so that as little condensate as
possible can enter from the exhaust gas system in order to avoid
ceramic breaks.
Select the installation location and installation position of the sensor so
that the sensor is possibly installed in downward sloping exhaust-gas
pipes and exhaust-gas systems in order to avoid a concentration of con-
densate in front of the sensor installation location (no indentations, pro-
jections, tearing edges).
• The installation angle position should be sloped at least 10° to the hori-
zontal (sensor tip pointing downward).
This prevents condensate from collecting between sensor housing and
sensor ceramics during operation in cold environments.
Fig. 3-1Installation Angle Position
• Assembly with special grease on fixing thread (e.g. Bosch lambda sen-
sor assembly paste, item number 1 987 123 020).
• Tightening torque: 50 Nm to 60 Nm, material properties and thread
strength must be dimensioned accordingly.
• Avoid impermissible heating of the cable gland close to the sensor.
• The use of cleaning or lubricating fluids as well as evaporating solids at
the sensor plug connection is not allowed.
