E.28 Signal A not available The device does not receive a signal. Either
there is no sensor connected or the
measuring path length is not correctly
programmed.

E.30 Signal C not available look at E.28
E.31 Signal D not available look at E.28
E.32 wrong path length stored The device does not receive a signal in
expected time. Either there is no sensor
connected or the measuring path length is
not correctly programmed.
E.33 calculation overflow The calculation exceeds the normal value
range. The parameters should be checked.
12. High temperature applications
If the temperature of the gas is higher than 250°C it is recommended to set the sensor back. Thus a
cold air buffer decouples the sensor better from the gas. If the sensors are installed like this it is
necessary to reprogram the evaluation unit. At first the measuring path length (R03) has to be
increased for the additional length. The second parameter that has to be changed is the sensor offset
(R29). In the example stated in the next figure the measuring path length (R03) has to be increased for
200mm (2 sensors) and the sensor offset R29 is 100mm.
