What to do if Beckman Coulter Laboratory Equipment rotor cannot achieve set speed?
- M
  maldonadogilbertAug 15, 2025
  If the rotor speed of your Beckman Coulter Laboratory Equipment cannot reach the set speed, there are several potential causes and solutions: * **Low line voltage:** Measure the line voltage while the centrifuge is operating. * **Imbalance detector tripped:** Turn the POWER switch to OFF (O), wait 30 seconds, and then turn it back ON (I). * **Thermal protector tripped:** Turn the POWER switch to OFF (O), wait 60 seconds, and then turn it back ON (I). * **Electrical failure:** Check the connections. If the issue persists, further assistance is needed. * **Worn motor components or motor failure:** If the motor bearings, commutator are worn, or the motor has failed, further assistance is needed.

What to do if Beckman Coulter Allegra 6KR thermal cutoff switch activated?
- C
  cowancliffordAug 25, 2025
  If the thermal cutoff switch has been activated on your Beckman Coulter Laboratory Equipment, follow these steps: 1. Turn the TIME knob to OFF and press the POWER switch to OFF (O). 2. Verify that the ambient temperature is within the specified limits. 3. Inspect the air inlet for obstructions and check the air-inlet filters for dirt. Clean as necessary. 4. Allow the motor to cool down (approximately 15 minutes with the door open). Then, press the POWER switch to ON (I) to reset the thermal protector circuit. If the problem continues, further assistance is needed.
