Replacement of spare parts and adjustment are done using standard tools of a maintenance engineer
specialised in laboratory equipment.
As a guide, a list is given in the appendix. If, for a particular reason, any other tools are required, these are
clearly specified in the relevant chapter.
5.1. IMBALANCE ADJUSTMENT
Adjustment procedure
When replacing the EPROM, all previously saved information is lost. In case of no calibration, to avoid
unecessery repairs, the EPROM contains imbalance threshold default value 350.
WARNING : CALIBRATION MUST ALWAYS BE PERFORMED.
Thanks to a self learning of the vibration peak by the microprocessor, the calibration is no longer a manual
procedure.
Carry out the following steps :
- Press simultaneously the ACCEL and BRAKING keys when the machine is switched on to access the
configuration menu.
- The speed display will indicate TEST during three second, then the timer display will indicate T-1.
- Pressing START key will display IMBAL on the speed display and on the timer display :
.
If the EPROM has just been replaced the default value will be 350.
.
A value between 0 and 999 is possible if a calibration has already been done.
- Fit an S40 rotor.
- Simulate the maximum tolerable imbalance by placing an 8g weight in one of the inserts.
WARNING : THE ROTOR MUST BE PERFECTLY BALANCED BEFOREHAND.
- Close the lid and press PULSE key.
- Wait until the machine has completed the learning run. At the end of the run a value between 200 and
700 is displayed. If the result is different repeat the calibration. If you cannot succeed in having a good
result, call the manufacturer’s service department.
- Press STOP key to exit the configuration menu.
