Troubleshooting

5.14.1 Status and error indication in HART® communication
Status and error indication in HART communication: The response code, according to the HART standard, is two 16-bit words after
the "Response code" bytes, respectively "Errors and Warnings" and "Status."
Error warning flags
Bit № Device Specific Error/Warning flags
0 No echo (Warning)
1 EEPROM is not detected (Error)
2 EEPROM checksum error detected (Error)
3 OCT input side integrity error (Error)
4 OCT output side integrity error (Error)
5 OCT item count is <2 (Error)
6 Input level over the OCT input side (overload)
(Warning)
7 EEPROM reinitiated (EEPROM layout damaged
or missing) (Error)
8 -
9 Echo in near blocking range (Warning)
10 Echo in far blocking range (Warning)
11 -
12 One or more slave controller(s) failure! (Error)
13 Relay failure (Error)
14 Parameter table integrity error (Error)
15 Sensor failure (Error)

Meaning, possible reason, solution
The device cannot detect the surface to be measured, so there is no
echo or there are too many echoes due to interference. Ensure
proper installation! If the problem persists, contact the dealership.
The parameter memory of the device is compromised. Contact
dealership.
Some data stored in the device's parameter memory has been
corrupted. Factory default settings are restored by the device. If the
device's parameter memory fails frequently, contact the dealership.
The data in the left (L) column of the Output Conversion Table (OCT) is
not incremental. Correct it.
The data in the right (R) column of the Output Conversion Table (OCT)
is not incremental. Correct it.
Too few points are entered into the Output Conversion Table (OCT). At
least two (i ≥ 2) points (elements) must be entered.
The measured level, as the input value of the OCT, points out of the
range entered in the left (L) column of the OCT. Enhance the range.
The data structure stored in the device's parameter memory is
corrupted. The device restored the factory default settings. If the
device's parameter memory fails frequently, contact the dealership!
-
The measured surface is too close, within the device's minimum
measuring range (Xmin). Set the close-end blocking (P05) to a
smaller value, or change the technology to ensure that the surface to
be measured does not come so close to the sensor of the device.
The measured surface is too far, outside the device's maximum
measuring range (Xmax). Set the far-end blocking (P05) to a larger
value, or change the technology to ensure that the surface to be
measured does not get so far from the sensor of the device.
-
One of the device's auxiliary controllers has failed. The probability of
a firmware error is high. Performing a complete firmware update
with Firmware flash (including synchronization) may solve the
problem. If unsuccessful, contact the dealership.
If the device has an optional relay, it is faulty. Contact the dealership.
The value of one or more parameters is not consistent with the
associated parameters. Correct the parameter value.
The radar sensor is faulty. There can be several reasons for this, e.g.,
the data connection with the radar sensor unit is inadequate or
insufficient energy available for the measurement. The terminal
voltage of the device must be above the prescribed minimum
in all circumstances! Check the voltage conditions of the loop by
measurement and change it as necessary so that the electrical
conditions for the terminals of the device are met. Contact the
dealership if the power supply voltage level is correct and the error
persists.
