Error description and remedy
All electronic components are at mains potential with the exception of the speed sensor (B1).
No display
•
Error description:
No display.
•
Cause of error:
–
No mains voltage.
Check fuses of in-house installation.
–
Mains input fuses (F1, F2) in the appliance plug are defective.
Check the mains input fuses.
–
Mains switch in the appliance plug is defective.
Mains voltage measurement:
EBA 200:
on plugs S102L and S102N / electronics (A1).
EBA 200 S, HAEMATOKRIT 200:
on plugs SL1 and SN1 / electronics (A3).
–
Electronics (A3) is defective (only for EBA 200 S, HAEMATOKRIT 200).
Measurement of the mains voltage on the plug S100 / electronics (A1), Pin 1 (L1) and Pin 3 (N).
–
Electronics (A1) is defective.
The yellow LED on the electronics (A1) must be illuminated or flashing.
–
Control panel (A2) is defective.
TACHO ERROR 1,
TACHO ERROR 2,
TACHO ERR 61.22,
FC ERROR 61.23
•
Error description:
–
TACHO ERROR 1:
During the centrifugation run, the control panel (A2) no longer receives
speedometer pulses from the speed sensor (B1).
–
TACHO ERROR 2:
After starting the centrifugation run, the control panel (A2) receives no
speedometer pulses from the speed sensor (B1).
–
TACHO ERR 61.22:
During the centrifugation run, the electronics (A1) no longer receives
speedometer pulses from the speed sensor (B1).
–
FC ERROR 61.23:
During the centrifugation run, the speed measurement on the electronics
(A1) detected an impermissible speed deviation.
•
Clear error message:
Wait until the rotor has come to a standstill and the symbol (lid locked) is
displayed. Afterwards, carry out a MAINS RESET.
•
Cause of error:
–
Speed sensor (B1) defective or loose contact.
Check the function of the speed sensor (B1); see chapter 7.4.4.
Measurement on plug S602 or S504 / electronics (A1):
Plug S602: EBA 200
Plug S504: EBA 200 S, HAEMATOKRIT 200
Operating voltage: Pin 1 – Pin 3 (+5 VDC).
Speedometer pulses: Pin 1 – Pin 2 (signal). Slowly rotate the rotor by hand.
–
Loose contact on the plug S601 or S501 / electronics (A1).
Plug S601: EBA 200
Plug S501: EBA 200 S, HAEMATOKRIT 200
–
Control panel (A2) is defective (not with error messages
TACHO ERR 61.22
and
FC ERROR 61.23
).
–
Electronics (A1) is defective.
