Error 2 Imbalance sensor is defective.The idle value is outside of the limits or

the measuring value is absolutely incor-

rect. Error occurs only if an incorrect idle

value is applied for at least 3 sec.

Device does not start or brake.

The old Imbalance-recognition PCB is

still in use (cable colors at plug X 10:

white/black/red/blue).

Is the customers rotor damaged orloaded asymmetrically?

Is the centrifuge placed on a

horizontal, stable and resonance-free

work surface?

Was the centrifuge moved and just put

into operation? If so, let the centrifuge

run at maximum speed.

Is the sensor idle value stable and

within the tolerance (670 100)?

Adjust imbalance PCB and carry outimbalance adjustment. Replace

imbalance PCB in case of no success.

Was the imbalance PCB adjusted

correctly after being replaced or after

the motor being replaced?

Following replacement of the motor,

the PCB Imbalance or the PCB

Control, was a fresh imbalance

calibration performed?

Was the correct rotor with the correctweighs used for an imbalance

adjustment?

Was the plug reconnected correctly to

the PCB after a repair?

Check plug X10.

Use new Imbalance-recognition PCB

from -02 onwards (cable colors at plug

X 10: White/brown/green/yellow).

Changerotor W-Error 28Load-cycle count of 100.000 reached

(from software 3.0 onwards with PCB in SMD

technology).

The warning is displayed 3 times following the

run after 98,000, 99,000 and 99,600 runs.

It appears after every run after 100,000 runs.

Notes:

The "Change rotor" message is conceived of

as a warning and provides the customer and

the service technician the opportunity to

evaluate the condition of the rotor.

Use of a rotor with load change limitation that

has exceeded the 100,000th load change is

not permitted!

It must be noted that the load change numbers

(CLyy) can only be reliably evaluated when:

1. In case of repairs the data of the

defective PCB Control has been taken

over by the new PCB Control. (Saving

does not take place in the EPROM

program, but instead only on the PCB.)

2. The load change counter has been resetwhile exchanging a rotor.

3. The customer uses only a rotor of the

same type in the centrifuge.

4. The customer uses several centrifuges

and each rotor is allocated to one

centrifuge.

5. The fixed-angle rotors CL13 and 17 have

no load change limitation. It is not

necessary to discontinue operation.

Only the fixed-angle rotors CL14 and 18

and all swing-bucket rotors have a load

change limitation.

Only centrifuges equipped with the PCB

Control in SMD technology as of software

version 3.0 enable a load change number

(CLxx).).

Evaluate the load change table withservice program SE 14.

The load change numbers (CLyy) are

measured separately for each rotor

type.

Immediately discontinue operation of

the rotor if necessary, see notes.

Prior to using a new rotor, delete the

load change table for the rotor type with

service program SE 14.

By actuating simultaneously the PLUS and MINUS buttons (cursor keys) the device is switched over to

the service indication mode. This does not depend on the operational mode the device is currently in.

The run of the centrifuge is not influenced by this.

The indications are continued by pressing the PLUS button.

During a run only the indications no. 1...6 are accessible (from START to opening the lid or resetting to

the nominal value indication with START).

During a fault the indication automatically jumps to 9. After that you can start again switching to different

indications (error indication with display of the error location and for error 6 of the FC error numbers).

The FC parameters can be checked during a standstill and while the lid is closed (FC on!) with the

centrifuge. The limits for switching off (imbalance) and statistical data and fixed programs are also

stored in the EEPROM.

When calling up the program via the serial interface code no. 64, additionally the interface is set to

20 H/disable.

Cycle program

START Program 7

This program is used for a continuous test (e.g. factory test) of the centrifuge. Always 3 runs with a

subsequent interval of 1 min are carried out. After the 4th run the interval is 10 min. The FC is switchedoff after each run.

The nominal values of the run can be changed after the start of the service program (pre-setting:

nominal rotational speed of the rotor, 10 min, 4 C).

Display of the pre-set nominal values, it is possible to change them

Imbalance calibration carried out by a service technician

START Program 10

The centrifuge determines the imbalance cut-off value of the individual rotors from all rotors in a rotorgroup.

Oneangled rotor (W)and oneswing-bucket rotor (A)must be used from each rotor group. As a

rule, this should be carried out with the standard rotors.

Exception: Use (A) Rotor A-4-81 if avaliable.

Standard rotors: Centrifuge 5804 / 5804R (W) F34-6-38 and (A) Rotor A-4-44

Standard rotors: Centrifuge 5810 / 5810R (W) F34-6-38 and (A) Rotor A-4-62

Prepare the weights: G1/G2/G3

It is possible to weigh the weights yourself using Eppendorf tubes. Filled 2.0 ml tubes (approx. 3.2 g) are

recommended. The weight of the tube must also be taken into consideration.

With swing-bucket rotors, these should be placed flat, loose and without an adapter on the bottom of

the swing-bucket. With the angled rotor F34-6-38, water should be pipetted directly into the empty

bores. MTP rotors can be loaded and then filled with one MTP each.

Procedure for imbalance calibration

1. Insert fixed-angle rotor(W). (Use the present rotor lid).

2. Call up the service program: Hold down both cursor keys and switching on the device.

Display : SE 1

3. Using the cursor key, call up SE 10

4. Insert the tube with G1.

5. Close lid. Start run: Start

6. Three calibration runs are performed automatically. The lid opens automatically.

7. Insert weight G2.

8. Close the lid and wait until three further calibration runs have been performed.

Lid opens automatically.

9. Insert weight G3. Close lid. Start run: Start (Centrifuge must show "Imbal" and switch off.)

10. Open lid: Open.

11. Remove fixed-angle rotor (W) and insert swing-bucket rotor (A).

12. Using the corresponding imbalance amounts G1, G2, G3, carry out the procedure described in

points 2. to 9

13. Switch off the device. Remove the imbalance weights and then switch on the centrifuge again as

normal.

Note:

An imbalance adjustment must be carried out every time the motor, PCB Control or PCB Imbalance is

replaced or when the rotor is inserted!

After the motor has been replacedl or when the centrifuge has not been used for a long period, it should

run for approximately five minutes at maximum speed in order to ensure

that the vibration mounts have the normal degree of hardness.

Determination of the acceleration and braking times (for factory checks)

START Program 11

the max. rotational speed of the rotor in use)

close the lid

START run

Display of the acceleration time in seconds (at 97 % of the rotational speed nominal value)

STOP start of the measurement of the braking time

Display braking time

STOP return to the program selection

Overspeed cut-off test (Test with Rotor)

START Program 12

Close the lid

The software sets a rotational speed above the switching-off limit. If the device operates correctly, itswitches itself off when reaching the switching-off rotational speed and stops without braking.

If the device is not switched off, the run must be stopped immediately by hand!

The device must be switched off!

On switching on again the centrifuge brakes and is then again in the normal operational mode.

Overspeed cut-off:

The overspeed cut-off is about 300 1/min above the nominal speed of the rotor in use.
