Alarm (description)
Explanation
/Action
E1
No transmission
Transmission is too low.
The dust level in the optical path may be too high. If the
fault remains at good visibility it may be necessary to
clean the process windows and verify alignment.
E12
Ext. temperature bad
The state of the digital input indicates that the
temperature value from the external sensor is bad.
Solve the problem caused by the external temperature
sensor.
E16
Ext. pressure bad
The state of the digital input indicates that the pressure
value from the external sensor is bad.
Solve the problem caused by the external sensor.
E20
Ext. temperature source
disconnected
Configuration Error.
Contact Siemens support.
E21
Ext. pressure source disconnected
Configuration Error.
Contact Siemens support.
E29
Compensation temp. file range
The process temperature deviates from the operational
range of this SITRANS SL application. The deviation is
so large that no measurement value can be produced.
Delimit process temperature or verify that the
temperature sensor produces correct measurements.
E30
Compensation pressure file range
The process pressure deviates from the operational
range of this SITRANS SL application. The deviation is
so large that no measurement value can be produced.
Delimit process pressure or verify that the pressure
sensor produces correct measurements.
E31
CurveFit temp. file range
The process temperature deviates from the operational
range of this SITRANS SL application. The deviation is
so large that no measurement value can be produced.
Delimit process temperature or verify that the
temperature sensor produces correct measurements.
E32
CurveFit pressure file range
The process pressure deviates from the operational
range of this SITRANS SL application. The deviation is
so large that no measurement value can be produced.
Delimit process pressure or verify that the pressure
sensor produces correct measurements.
E33
CurveFit gas file range
Internal error when reading the curve fit compensation
file.
Contact Siemens support.
E59
Sensor temp. comp. file range
The ambient temperature at the sensor is outside the
specifications.
Check that the ambient temperature is within the
specifications and ensure that the system is not exposed
to direct sunlight.
E63
A0 outside measurement range
The current measurement value is outside the scaling
range for the analog output signal.
Change the scaling of the analog output.
E64
A1 outside measurement range
The current measurement value is outside the scaling
range for the analog output signal.
Change the scaling of the analog output.
