Troubleshooting

4-1

This section lists possible malfunctions, together with probable 
causes and corrective actions. Maintenance procedures are given 
in Section 5. For any problems not covered here, contact Beckman 
Coulter Field Service (1-800-742-2345 in the United States; 
worldwide offices are listed on the inside back cover of this manual) 
for assistance.

NOTE

➠

It is your responsibility to decontaminate the 
instrument, as well as any rotors and/or accesso-
ries, before requesting service by Beckman 
Coulter Field Service.

USER MESSAGES

If a problem occurs during operation, the rotor will decelerate to a 
stop and an error code will appear on the 

SPEED 

display. Messages 

may result from incorrect input (such as exceeding allowable speed 
for a rotor) or from an equipment malfunction. Refer to Table 4-1 to 
determine the nature of the problem. If you are unable to correct the 
problem, call Beckman Coulter Field Service. To help diagnose and 
correct the problem, provide as much information as possible:

• Write down the error number that appears on the display.

• Note the operating situation when the error occurred (rotor in use, 

speed, load type, and so forth).

• Note any unusual environmental and/or operating conditions 

(ambient temperature, voltage fluctuations, and so forth).

• Include any other useful information.
