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 />
