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 fromservice 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 thenturned clockwise/counterclockwise.

Error Cause Remedy

Er 2 Imbalance switch, at standstill, defective.

R: Centrifuge will not start.

Check switch, cable, plug.

– Check/adjust imbalance switch with service display SE 3.

– Load rotor symmetrically.

– Check switch, cable, connector.

– Replace Control PCB.

Er 3 No rotational speed pulses during running or when starting.Speed measurement system defective.Drive defective.The rotational speed is measured at the motor.Error remains active after power is cut.

R: The centrifuge decelerates unbraked. The centrifuge remains locked for 5 minutes.The lid cannot be opened until the error display is cleared.

Tubes collide with lid of centrifuge during start.

– Leave centrifuge switched on for > 5 minutes. Start again.

– Check motor speed sensor.

– Replace Converter PCB.

– Check tubes. Tubes too long or wrong adapter used?

– Check plug connections.

Er 3-0 When the centrifuge is powered up Err. 3 is signaled. See Er 3.

SE8 Display operating hours and number of centrifuge runs

Call SE 8.


Display:

xxxxx = Operating hours

Display:

yyyyyy = Number of centrifuge runs

The display switches over after 3 s!

The number of centrifugations is also displayed for 3 s, after this the program terminates automatically!


The test is performed without rotor!

Call SE 9.


Display:



Quit the program with the "short" button when the motor has come to a standstill.

SE 12 Setting imbalance

Call up SE 12.

– Set rotational speed

– Insert and load rotorTable for imbalance adjustment/testing, see Chapter 5

– Close lid

Start program with "start/stop" key.

Display when emergency switch activated:

Service program is exited. It is possible to open the lid while the rotor is at a stillstand.

Note:The imbalance setting can be checked with SE 12 without accessing the cooling aggregate.

SE 13 Limitation of the fan speed of the condenser

Call up SE 13.


Display when emergency switch is activated:

Change setting: "time" dialSave setting and end program: "start/stop" key.

Note:The setting of the condenser fan is possible within a range from "20 – 32". A change makes sense when the room tempe-rature is very high or when the voltage is lowThe standard lowest setting for the fan speed is "20". "25" must be set for 100 volt devices following the replacement of the PCB Control 5702 R.The setting is maintained after the device is switched off or following initialization.

1. Measurement, acceleration and braking times

Call SE 1.


Display:

Start the measurement run by pressing the "start/stop" button. Machine accelerates up to the final speed.The cooling unit is switched on only during braking ( xx=-- oder Kompressorfrequenz).

xx.x = Acceleration time 0..4268 rpm (97 %) in sec

Press "start/stop" to stop the run. Machine brakes until standstill.

xx.x = Braking time

Switching off the lid motoru = 1 – Switching off the lid by intermediate step during opening and closing.u = 2 – Lid closedu = 3 – Excess current cut-off, lid open

The lid motor is controlled during closing by pressing "rcf" (leave a pause of 1 s between each pulse).



Call SE 4.

Press "start/stop" to start the program.A short display test follows, all characters appear for approx. 3 s, a long beep sounds and the program buttons light up blue.

Press all the buttons in succession, in the sequence: "rpm/rcf" button, "open", "fast temp" and "short".
