IMBALANCE
Error cause Imbalance on motor axle.
Error
consequence
The centrifuge slows down until the “open the lid” release
occurs.
Further cooling until NOMINAL temperature is reached.
Error remedy
• Weight difference in rotor components.
• Supporting lugs not lubricated.
• False IMBALANCE MODE is set (see chapter "Imbalance
Mode").
• Imbalance switch not connected.
• Imbalance switch is defective.
• Loose contact in cable or plug.
• CC to CP is defective.
• CP or SB is defective.
Measurement Also see at SB-X3 and CP-X1 (PIN 12)
Error code reset Perform an MR.
CONTROL - ERROR 04
Error cause LL is open during centrifugation.
Error
consequence
Slowing down until the ”open the lid” release occurs.
Further cooling until NOMINAL temperature is reached.
Error remedy
• LL is defective and can be opened during centrifugation.
• Loose contact in cable or in plug.
• CC to CP is defective.
• CP or SB is defective.
Measurement Also see at SB-X5 (PIN 2 and PIN 6) and CP-X1 (PIN 5)
Error code reset Perform an MR.
N > MAX 05
Error cause Excess speed. The speed recognised by the speed sensor
(speedometer) is 250 RPM greater than the n-max speed of
the rotor.
Error
consequence
The centrifuge slows down until the ”open the lid” release
occurs.
Further cooling until NOMINAL temperature is reached.
Error remedy
• Insulation of speed sensor (speedometer) cable is
defective.
• Loose contact on speed sensor (speedometer) cable.
• Speed sensor (speedometer) is defective.
• CC to CP is defective.
• CP or FC or SB is defective.
