The consecutive number (cause of error) provides for more detailed localization of the error. The time before the display is cleared depends on the operational status (centrifuge accelerating, braking or stopped). Only then does the controller perform a reset. Error list Note: The error display shows Er 3, 4, etc. No rotational speed pulses during running or when starting. Speed measurement system defective. Drive defective. The rotational speed is measured at the motor. R: The centrifuge decelerates unbraked. The centrifuge remains locked for 5 minutes. The lid cannot be opened until the error display is cleared. Er 3-0 When the centrifuge is powered up Err. 3 is signaled. See Er 3. Er 3-1 No pulses after starting centrifuge. Centrifuge brakes. See Er 3. Er 3-2 Pulse failure during running. Er 5-1 When the centrifuge is powered up the rotor rotates. The lid switch is open. See Er 5. Er 5-2 Rotor rotates. Er 6-5 Wrong Converter PCB ID after power-up. See Er 6. Er 6-6 Safety circuit for release of Converter PCB defective. Er 9-1 Save running data. See Er 9. Er 9-3 Initialization. See Er 9. Er 9-4 Save operating hours. See Er 9. Er 10 EEPROM read error. See Er 9. R: Set defaults, data of last run are lost. Er 14 EPROM checksum error after power-on. Error in program memory, EPROM defective. Er 15 In b Imbalance shutdown occured during a run. Er 16 Error in inquiry to Converter PCB. See Er 2. R: Centrifuge decelerates unbraked. See Er 3. R: Centrifuge shuts down and decelerates unbraked. Er 16-2 Error after telegram repetition. See Er 3. Er 17 Error transmitting select telegram to Converter PCB. See Er 6. R: Centrifuge shuts down and decelerates unbraked. Temperature sensor at condenser defective. Mains frequency for condenser fan faulty on Converter PCB. Replace Converter PCB. R: Fan is switched on or off. Centrifuge can be operated. R: Centrifuge shuts down, braked deceleration. Mains voltage generally too low or too high. Heating switch relay defective. -vezouze.fr/media/donnay-model-41189a-manual.xml
