To wire the ES430.1 with the sensors
1. If there is a protective cap at the “Sensor” port, remove it.
2. Connect the sensor cable to the “Sensor” port of the ES430.1.
3. Connect the LSU4.9 sensor to the RB150 plug (Code 1) of the
sensor cable.
To wire the control of the heater control
1. Pull the cable end out of the shrinkage tube of the sensor
cable.
2. Connect the end of the cable to a suitable signal (e.g. terminal
15).
To wire the analog output of the ES430.1 (only CBAL451.1, CBAL4515.1)
1. Connect the BNC socket of the sensor cable to a data acquisi
-
tion system, e.g. the analog input of the test stand.
To wire the sensor with the supply voltage
1. Connect the supply voltage connector of the sensor cable to a
suitable power supply for the sensor.
Note the color coding of the connectors.

Calibrate to Air
A semi-automatic calibration of the sensor / ES430.1 system can be carried out
in the calibration software.
Applications:
• Compensation of tolerances of the lambda sensor,
• Compensation of aging effects of the lambda sensor (can still be used in
spite of a weaker signal) and
• Determination of whether a sensor deviates from the desired values.
Normal ambient air is used as air reference. To be able to execute a correct
calibration in extreme atmospheric pressure or temperature conditions, a dif
-
ferent value from the default value of 20.9% can be entered as desired oxygen
value.
TIP
The correction factor determined is sensor-specific and is stored in the mod
-
ule. If a different lambda sensor is connected, the correction factor has to be
reset and a new system calibration executed.
