OMICRON 175
Error and warning messages
14 Error and warning messages
001.xxx Error [001] No valid CT software!
Reason: No valid software in the device Flash memory or incorrect checksum.
Solution: Insert a Compact Flash card with valid software (CTAnalyzer.bin) in the Omicron
directory and switch the CT Analyzer off and on again.
002.xxx Error [002] Can't open file!
Reason: The firmware cannot read the file CTAnalyzer.bin from the Compact Flash card since the
CF card or the file is missing.
Solution: Insert a Compact Flash card with valid software (CTAnalyzer.bin) in the Omicron
directory and switch the CT Analyzer off and on again.
003.xxx Error [003] Download error!
Reason: The downloaded software is corrupt.
Solution: Insert a Compact Flash card with valid software (CTAnalyzer.bin) in the Omicron
directory and switch the CT Analyzer off and on again.
100.xxx Warning [100.xxx] CT resistance > 3000 Ohms.
Reason: The resistance measured during primary or secondary winding resistance measurement is
> 3000Ω.
Solution: The test cannot be continued. Check the connections to the CT. If the connections are ok,
the CT resistance is > 3000Ω. Such CTs cannot be tested using the CT Analyzer.
101.xxx Warning [101.xxx] Timeout during measurement. No constant winding resistance can be
determined within 10 sec.
Reason: The CT Analyzer cannot determine a constant winding resistance within 10sec. during
primary or secondary winding resistance measurement.
Solution: The test cannot be continued. Check the connections to the CT.
110.xxx Warning [110.xxx] The impedance of the CT is too high.
Reason: The impedance of the CT or the load is too high to reach the minimum toggle frequency of
0.2Hz / 0.8Hz.
Solution: The test cannot be continued. Check the connections to the CT. If the connections are ok,
it is not possible to test this CT due to its too high inductance.
111.xxx Warning [111.xxx] Inductance of load too low.
Reason: Measurement frequency is too high and cannot be decreased because of too low CT
inductance.
Solution: The test cannot be continued. Check the connections to the CT. If the connections are ok,
it is not possible to test this CT due to its too low inductance.
112.xxx Warning [112.xxx] Measurement error, reduce noise level.
Reason: It is not possible to obtain stable measurement results due to incorrect wiring, wiring short-
circuit, connected load or external interferences.
Solution: Check the wiring. The primary side of the CT must not be short-circuited. Disconnect the
primary side of the CT from the transmission lines, connect one primary side terminal to
PE and open the other one. Use the delivered original coax cables for measurement (see
section 3.7.2 "Noise reduction techniques" on page 46). Make sure that no burden is
connected to the secondary side of the CT. This error may also indicate a winding short
circuit of the CT.
113.xxx Warning [113.xxx] Test not successful. Kneepoint not found.
Reason: Knee point for specified standard not found.
Solution: The current required to reach the knee point for the specified standard cannot be delivered.
The CT cannot be tested up to the knee point voltage.
114.xxx Warning [114.xxx] Low inductance detected during excitation measurement.
Reason: Low inductance was measured during the excitation test.
Solution: Verify that the primary side of the CT is not short-circuited.
This warning can also occur for CTs with very low excitation loss and high parasitic
capacitance.
