User Messages
CAUTION
If the message SEr appears on the display, do not press any keys while the
message is displayed. Turn the centrifuge power off (O) and back on (I) to clear
the message. This message indicates that you have inadvertently accessed the
service mode. Pressing any keys while in this mode could erase the centrifuge
memory and critically interfere with future operation.
If a problem occurs during operation, the rotor decelerates to a stop, an error code appears on the
SPEED
display, and the centrifuge emits a series of audible tones to alert the operator to the error
condition. Such problems may result from incorrect input or from an equipment malfunction. Refer
to Table 3.1 to determine the nature of the problem and recommended actions. If you are unable to
correct the problem, call Beckman Coulter Field Service. To help diagnose and correct the problem,
gather as much information about the situation as you can:
•
Write down the error number that appears on the display.
• Note the operating situation when the error occurred (rotor in use, speed, load type, etc.).
•
Note any unusual environmental and/or operating conditions (ambient temperature, voltage
fluctuations, etc.).
•
Add any other information that may be helpful.
NOTE
Instructions for disabling the audible tones are in CHAPTER 2, Operation .
