Explanation
/Action
E10
Process temp. range
The process temperature input is out of the range
specified for the application.
Check the process temperature.
E11
Process pressure range
The process pressure is out of the range specified for the
application.
Check the process pressure.
E13
Ext. temperature low limited
The analog input from the temperature sensor is out of
range.
Check the connected temperature sensor.
E14
Ext. temperature high limited
The analog input from the temperature sensor is out of
range.
Check the connected temperature sensor.
E17
Ext. pressure low limited
The analog input from the pressure sensor is out of
range.
Check the connected pressure sensor.
E18
Ext. pressure high limited
The analog input from the pressure sensor is out of
range.
Check the connected pressure sensor.
E35
O
2
outside range
Currently calculated gas concentration is outside the valid
range for this application.
Check whether the measured gas concentration is
reasonable. If so, contact Siemens support to evaluate if
the measuring range can be increased. If the
concentration seems incorrect it may be necessary to
check path length, temperature correction and pressure
correction.
E41
CO outside range
Currently calculated gas concentration is outside the valid
range for this application.
Check whether the measured gas concentration is
reasonable. If so, contact Siemens support to evaluate if
the range can be increased. If the concentration seems
incorrect it may be necessary to check path length,
temperature correction and pressure correction.
E67
Measurement quality
The optical power is too low, or the input signal too noisy
at the detector to guarantee an accurate measurement.
Clean the process windows and verify alignment. Also
make sure that the process gas is not too turbulent or the
purging rate too high.
E15
Ext. temperature constant
The external temperature source signal is frozen.
Check the connected temperature sensor.
E19
Ext. Pressure constant
The external pressure source signal is frozen.
Check the connected pressure sensor.
E23
Ext. temperature uncertain
The external temperature source signal is not reliable.
Check the connected temperature sensor.
E24
Ext. pressure uncertain
The external pressure source signal is not reliable.
Check the connected pressure sensor.
