Appendix C. Sensor Status
Values
Table 42 Sensor Status Values
Value Description Interface
0
The sensor is working properly.
Serial/Analog
1)
1
Not measured yet. Serial/Analog
2
Interface not initialized. Serial
3
Communication time‑out occurred. Serial
4
Unknown data received. Serial
5
Communication is functioning, but the sensor reports errors. Use the sensor's
own service interface to find out the cause.
Serial
6
Sensor communication is paused because service connection to the sensor is
open.
Serial
7
Message sequence numbers are overlapping in the Autotrac satellite
transceiver interface.
Serial
8 … 19 Reserved. N/A
20
Excitation failure caused by an overload in the excitation output. Analog
21
Input voltage is out of range or the A/D conversion has failed due to an
internal error.
Analog
22
The sensor is disconnected or sensor cable is damaged. Analog
23
Sensor output exceeds the minimum or maximum limits. The limits are
defined in the Measurements view.
Analog
24
Change in sensor output exceeds the maximum step. The limits are defined in
the Measurements view.
Analog
25
Internal configuration error occurred. Analog
26
Error in reference measurement. This is usually caused by a damaged sensor
or QML data logger or electrical interference.
Analog
27
Internal voltage error occurred or the QML data logger is damaged. N/A
28
Reserved. N/A
29
Data is invalid for an unspecified reason. Analog
30
The measurement or the sensor has been manually disabled. Serial/Analog
99
Sensor status not supported. Serial/Analog
1) Analog includes also counter/frequency interfaces.
