NO COOLING
Error cause No cooling in centrifuge chamber. Overtemperature at
condenser, temperature > 60°C.
Error
consequence
Cooling switches off.
Continuance of centrifugation until temperature switch in the
centrifuge chamber triggers and “ERROR 52” appears.
The centrifuge slows down until the “open the lid” release
occurs.
Error remedy
• Condenser soiled.
• Loose contact in plug.
• SB is defective.
• Fan is defective.
• Sensor cable B2 is defective.
Measurement Also see at CB X2.
Error code reset Perform an MR.
°C / * - ERROR 52
Error cause Overtemperature in centrifuge chamber.
Error
consequence
The centrifuge slows down until the ”open the lid” release
occurs.
Error remedy
• Sensor cable B1 is defective.
• Loose contact in plug.
• CP is defective.
• CB is defective.
Measurement Also see at CB-X3 (PIN 1 and PIN 2) and CP-X101 (PIN 4)
Error code reset Perform an MR.
°C / * - ERROR 53
Error cause Temperature sensor in centrifuge chamber has a short circuit
or a discontinuity.
Error
consequence
The centrifuge slows down until the ”open the lid” release
occurs.
Cooling switches off.
Error remedy
• Temperature sensor is defective.
• Sensor cable B1 is defective.
• Loose contact in plug.
• CP is defective.
• CB is defective.
Measurement Also see at CB-X3 (PIN 5 and PIN 4), CP-X101 (PIN 8)
