- F - Rotor code
Error
No rotor code after start-up.
Error
consequence
Drive switches off after 15 sec. No brake effective
Error cause
•
Start-up took place without the rotor.
•
Motor is defective.
•
Power board (A1) defective Speed sensor (speedometer)
defective, or loose contact on plug.
Measurement
1. A1 / S502 pin 2 (GND) to pin 3 (+U
B
)
2. Speed sensor plug S502 , pin 4 – pin 2 GND (pulses: 0V, 15V,
0V, 15V etc. / 6 pulses per revolution). See also section 9.2
Error code reset Perform a MAINS RESET after standstill.
rot... – New rotor identified
Each time a centrifuging run is started, the centrifuge recognises the rotor code of the
installed rotor with the help of a sensor. This means that the nominal speed of the
installed rotor cannot be exceeded.
After the identification of a newly installed rotor the drive will cut off and its rotor code
"rot ..." will be displayed. Example: rot 3 = rotor code 3.
Press the
START
key.
If the speed rating of the newly installed rotor is lower than the last speed entered, the
speed rating of the newly installed rotor will be displayed.
If the speed rating of the newly installed rotor is higher than the last speed entered, the
last speed entered will be displayed.
Press the
START
key to start the centrifugation run.
