37 Faults<br />
If the fault cannot be eliminated with the help of the fault table, please inform Customer Service.<br />
Please specify the type of centrifuge and the serial number. Both numbers can be found on the name plate of the<br />
centrifuge.<br />
Perform a MAINS RESET:<br />
− Switch off the mains switch (switch position "0").<br />
− Wait at least 10 seconds and then switch on the mains switch again (switch position "Ι").<br />
Message / fault Cause Remedy<br />
No display --- No voltage.<br />
− Check supply voltage.<br />
Overvoltage protection tripped out.<br />
Triggering the automatic circuit breaker<br />
(only for types 5650-01, 5660-01 and<br />
5660-51).<br />
− Switch automatic circuit breaker<br />
ON again; refer to Chapter<br />
"Switch on automatic circuit<br />
breaker" (only for types 5650-01,<br />
5660-01 and 5660-51).<br />
− Mains switch ON.<br />
TACHO - ERROR 1, 2, 96 Faulty speedometer.<br />
− Open the cover.<br />
Motor, electronics defective.<br />
− Switch off the mains switch<br />
(switch position "0").<br />
− Wait at least 10 seconds.<br />
− Turn the rotor vigorously by hand.<br />
− Switch on the mains switch again<br />
(switch position "Ι"). The rotor<br />
must turn during switch-on.<br />
IMBALANCE --- The rotor is unevenly loaded. − Open lid.<br />
− Check the loading of the rotor,<br />
see chapter "Loading the rotor".<br />
− Repeat the centrifugation run.<br />
CONTROL - ERROR 4.1 - 4.5, Error in lid locking or lid closure.<br />
6<br />
N > MAX 5 Rotation too fast<br />
− Perform a MAINS RESET.<br />
N < MIN 13 Rotation too slow<br />
ROTORCODE 10.1, 10.3 Incorrect rotor coding<br />
MAINS INTERRUPT --- Power failure during the centrifugation run. − Open lid.<br />
(The centrifugation run was not finished.) − Push START button.<br />
− Repeat the centrifugation run if<br />
necessary.<br />
