3 Error lists / Troubleshooting 3-1 eppendorf Service Manual Centrifuge 5702 / 5702 R / 5702 RH – 3 Error lists / Troubleshooting Note: R = Response of centrifuge when the error is reported. Display: Cause and response of centrifuge. The consecutive number (cause of error) provides for more detailed localization of the error. It can be read from service program 8 (5702) or service program 9 (5702 R / 5702 RH). After power-off the display shows "OFF". The time before the display is cleared depends on the operational status (centrifuge accelerating, braking or stopped). All operational states can only be reset if the "OFF" display is cleared between power-off and power-on ! Only then does the controller perform a reset. Note: The error display shows Er 3, 4, etc. Er 3-0, 3-1 only appears when the "speed" dial is held down for six seconds and then turned clockwise/counterclockwise. Error Cause Remedy Er 2 Imbalance switch, at standstill, defective. R: Centrifuge will not start.
