7. ERROR HANDLING
7.1 S
TATUS AND ERROR REPORTING IN HART COMMUNICATION
Status and error indication in HART communication: the HART standard “Response code” is two 16-bit words after the bytes, in "Error" "Status" order.
Bit № “Device Specific Error” (DSE) flags Meaning, possible cause, solution.
0 No echo The device does not "see" the liquid surface to be measured, so there is no echo or too much echo due to interference.
Make sure it is installed correctly. The appliance is defective, contact service.
1 EEPROM is not detected The device parameter memory is faulty, contact service.
2 EEPROM checksum error detected Some data stored in the device parameter memory is corrupted. The device has reset it to its default settings. If this
happens frequently, the device parameter memory is faulty, contact service.
3 OCT input side integrity error In the left (L) column of the Output Conversion Table (OCT), the data is not monotonically increasing. Please correct it!
4 OCT output side integrity error In the right (R) column of the Output Conversion Table (OCT), the data is not monotonically increasing. Please correct it!
5 OCT item count is <2 You have entered too few points in the Output Conversion Table (OCT). A minimum of two points (elements) (i >= 2) is
required. Please correct it!
6 Input level over the OCT input side (overload) As the input value of OCT, the measured level points out from the range of the (L) column specified in OCT. Expand the
range.
7 EEPROM reinitiated (EEPROM layout damaged or missing) The data structure stored in the device parameter memory is corrupted. It has been completely rebuilt with the factory
defaults. If this happens frequently, the device parameter memory is faulty, contact service.
8 „Long” ringdown After the emitted ultrasound packet, the sensor head shows a long echo reverberation. Improper highlighting (echo in
the throat) or device mounted in a steel flange that is not acoustically damped (flange ringing). Install the device as
specified.
9 Echo in near blocking range The surface to be measured is too close, within the device's minimum measuring range (Xm). Set the near block (P05)
smaller, or change the technology to ensure that the surface to be measured does not get so close to the device's
radiator.
10 Echo in far blocking range „SUB 0” The surface to be measured is too far out of the device's maximum measuring range (XM). Set the remote blocking
(P06) higher, or change the technology to ensure that the surface to be measured is not so far away from the device's
radiator.
11 Temperature sensor failure. The temperature sensor is defective, contact service.
12 One or more slave controller(s) failure! One of the device's auxiliary controllers has failed. The probability of a firmware error is high. You can solve the problem
by completely updating the program with "NiFlash" (including "Synchronization"). I F unsuccessful, contact service.
13 Relay failures If the device has an optional relay, it is defective, contact service.
14 Parameter table integrity error The value of one or more parameters is not consistent with the associated parameters. Correct the value of the
parameter.
15 Sensor power failure (low sensor power)->-> bit 11, Valid=0, HOLD=1 Not enough energy to emit (shoot) the ultrasound packet. The terminal voltage of the device must be above the specified
minimum in all circumstances! In general, the terminal voltage requirements of the devices inserted in the current loop
(loop current display, HART Modem, PLC current input, etc…) and the voltage on the wiring may be too high, or the
voltage supplying the loop may be relatively small. Check the voltage conditions of the loop by measuring and, if
necessary, modify it so that the electrical conditions for the terminals of the device are met.
