18/51
N < MIN 13
EC Insufficient speed; the slippage of the motor is too great.
The centrifuge regulation can adjust the speed by 5% max. (the limit of
adjustment).
The error is indicated if the ACTUAL speed is lower than the
NOMINAL speed minus 5%.
ES The centrifuge slows down until the ”open the lid” release occurs.
Further cooling until NOMINAL temperature is reached
ER
• Motor is labouring (damage to bearings).
• Motor has a short-circuited coil (coil is defective).
• Loose contact in the electrical connections.
• FC is defective.
Release signal to FC was interrupted during centrifugation.
ECR Open the LL.
Perform an MR.
CONTROL - ERROR 21 - 26
EC Internal error in CP.
ES The centrifuge slows down until the ”open the lid” release occurs.
ER
• CP is defective.
ECR Perform an MR.
N > ROTOR-MAX
EC Error in the entered program
ES Further operation is not possible.
ER SET speed or SET RCF is higher than the permissible rotor speed or
permissible rotor RCF.
ECR Carry out a MAINS RESET or open the lid.
Reduce the speed or RCF in the entered program to the permissible
rotor speed or permissible rotor RCF.
SER I/O - ERROR 30 and ERROR 31
EC CP has no connection to the component FC via serial interface.
ES The centrifuge slows down until the ”open the lid” release occurs.
ER
• CC to FC is defective.
• There is no voltage on FC.
• F2 overtemperature switch on brake resistor has opened or is not
connected.
• CP or FC is defective.
• Cable on plug S102 is not or wrong plugged
ECR Perform an MR.
