Centrifuge 5804/5804 R and 5810/5810 R
3 Error lists / Troubleshooting
3-2 Error lists/Troubleshooting
Error 2 Imbalance sensor is defective.
The idle value is outside of the limits or
the measuring value is absolutely incor-
rect. Error occurs only if an incorrect idle
value is applied for at least 3 sec.
Device does not start or brake.
The old Imbalance-recognition PCB is
still in use (cable colors at plug X 10:
white/black/red/blue).
– Is the customer´s rotor damaged or
loaded asymmetrically?
– Is the centrifuge placed on a
horizontal, stable and resonance-free
work surface?
– Was the centrifuge moved and just put
into operation? If so, let the centrifuge
run at maximum speed.
– Is the sensor idle value stable and
within the tolerance (670 ±100)?
Adjust imbalance PCB and carry out
imbalance adjustment. Replace
imbalance PCB in case of no success.
– Was the imbalance PCB adjusted
correctly after being replaced or after
the motor being replaced?
– Following replacement of the motor,
the PCB Imbalance or the PCB
Control, was a fresh imbalance
calibration performed?
– Was the correct rotor with the correct
weighs used for an imbalance
adjustment?
– Was the plug reconnected correctly to
the PCB after a repair?
Check plug X10.
–Use new Imbalance-recognition PCB
from -02 onwards (cable colors at plug
X 10: White/brown/green/yellow).
