5. Error Message
The following list of the error messages includes explanations for the Error Codes displayed
Error Codes 0 to 9, A, B, C do not occur during data entry.
Error Code Detected System Error Corrective Measures
0 Pipeline not full. Open shut off devices; fill pipeline; adjust Empty Pipe Detector

2
3 A/D-Converter
Positive or negative reference too small.
Flowrate greater than 130 %. Reduce flowrate, throttle shut off devices.
Check connection board and converter;
Reduce flowrate, change flow range
4 External zero return contact activated. Zero Return activated by pump or field contact.
5 RAM defective
1. Error 5 appears in display
2. Error 5 appears only in Error Register Program must be reinitiallized;
Contact ABB Automation Products Service department;
Information: Corrupted data in RAM, converter automatically executes a reset
and uploads data from EEPROM.

Primary data invalid
Reset forward totalizer or preset new values in totalizer.
Reset reverse totalizer or preset new values in totalizer.
Forward, reverse or difference totalizer defective.
Reset forward/reverse totalizer.
Check line frequency for Supply Power 50/60 Hz or for AC/DC Supply Power
Error in the Digital-Signal board.
Reduce flowrate
Increase flowrate
The data for the primary in the external EEPROM are invalid. Compare data in
submenu "Primary" with data listed on the Instrument Tag.
If the values agree, use "Store Primary" to reset the error message. If the data
are not identical, then it is necessary to first reenter the primary data and then
complete by using "Store Primary". Contact ABB Automation Products-Service

Check ground and ground signals. Adjustment can be made if the flowmeter
primary is filled with fluid and the flowrate is zero.
Reduce entry value, check adjust "Empty Pipe Detector".

92 Data in EEPROM corrupted
Data in ext. EEPROM corrupted Data in internal EEPROM invalid, for corrective measures see Error Code 5.
Data (e.g. Qmax, Damping) in external EEPROM invalid, access possible.
Occurs when function "Store data in ext. EEPROM" was not called. The error
message can be cleared using the function "Store data in ext. EEPROM"
93
94
Ext. EEPROM corrupted or not installed
Ext. EEPROM version incorrect
No access possible, component defective. If the component is not installed,
then it is necessary that the ext. EEPROM which belongs to the
flowmeter primary be installed.
The data base is not correct for the present software version. Calling the func-
tion "Load data from ext. EEPROM" initiates an automatic update of the exter-
nal data. The function "Store data in ext. EEPROM" clears the error message.
95
96 External Primary Data incorrect
EEPROM version incorrect See Error Code C.
Data base in the EEPROM has a different version than the installed software.
Clear the error by calling the function "Update".
97
98
Primary incorrect
EEPROM corrupted or not installed
The flowmeter primary data in the internal EEPROM are invalid. The error can
be cleared by calling the function "Load Primary", (See Error Code C).
No access possible, component defective. If the component is not installed.
then it is necessary that the ext. EEPROM which belongs to the flowmeter
primary be installed.
