Case1 -BC6000PLUS build-up pressure abnormal
Error Description:
During the startup process of BC-6000PLUS, the system reports an alarm that startup is not completed
and the self-built pressure is abnormal
Resolve Path&Solution:
1. Select Menu- > Status-> Temperature and Pressure, and check that the displayed 50kpa pressure
is only 5.8kpa. The manual pressure build-up and release test shows that the pressure does not
change significantly.
2. Check the pressure detection board: Connect the 50kpa gas tube to the 90kpa pressure sensor,
and observe that the pressure detection displays only the 6.1kpa and rule out pressure detection
board 50Kpa sensors
3. Whether the airway is leaking(Pinch method)
① Pinch the lower air tube of the 50kpa tank and check whether the pressure is normal.
② Pinch the pipeline between the gas tank and valve SV01/SV05, the 50kpa pressure is abnormal.
③ Pinch the pipeline between the gas tank and valve SV66/SV67, and verify that the 50kpa
pressure is normal.

Case1 -BC6000PLUS build-up pressure abnormal
Solution:
④ Pinch the pipeline from the SV66 valve to the DIL bath. The 50kpa pressure is normal.
⑤ Pinch the pipeline from the DIL bath to the SV72 valve. The 50kpa pressure is normal.
⑥During check of the DS cap assembly from valve SV72 to C34, bubbles are blown out in the tube of the
DS cap assembly. Abnormity is found. After replacing the SV72 valve, remove the fault.
Suggestions and
Summary
The startup pressure selftest shows that the SV72
valve is not closed tightly
and the pressure is leaking,
resulting in 50kpa pressure
build-up failure

Case2 BC6000PLUS LN floater status abnormal(0x32060074)
Error Description:
LN floater status error: LN reagent prime is slow. the
error can not remove
Error report principle
At the time points that the time sequence judges a
certain cistern is about to full, the system inquiries if
the floater ball in that cistern is at the upper position.
If not, the analyzer reports error.
Resolve Path
1、Since it is normal to prime other baths,
rule out is the air pressure error first
2、 Use a syringe and manually aspirate
LN reagent. The resistance is very high.
Therefore, the pipeline on LN is blocked.
3、 The abnormal part is found on the
tube from C13 connector to SV48.
4、 After replacing the black rubber tube,
the error is removed.

6.

Case2 6000PLUS LN floater status abnormal(0x32060074)
Summary:
1、 6000 series machines, LN reagent updated formula, LN reagent has the ability to corrode rubber
2、 Now the black rubber pipe has been replaced by the yellow pipe, and it needs to be replaced
with a new pipe during on-site maintenance

Case3 RBC clogging of the first sample after BC-6000 exit from standby mode
Error Description:
After exiting the standby mode, the first test sample is probably
alarm RBC clogging
Solution
1、 Check the special information of the abnormal sample. It is
found that the aperture voltage is abnormal, and the number of
RBC/PLT particles is extremely low or zero. It is suspected that
the RBC liquid leaks out during the test, or the blood sample is
not added to the reaction bath. The RBC test sample is the
second dilution sample from HGB, and the HGB test is normal,
so it does not support the idea that the RBC sample is not added.
2、 Replace the baths, counting valve (SV32)/bubble mixing
valve(SV05) and waste valve (SV42). The failures are not
solved
3、 Engineer go on observing and found that no diluent is
dispensed for the first sample after exiting the standby mode. the
back bath aspirates air, and an alarm indicating clogging is
triggered.
4、Finally replaced DP6 the fault was resolved
