Specifically, typically indicates a failure in the lid locking mechanism or the associated sensor feedback loop. Modern centrifuges utilize a complex safety interlock system to ensure the lid cannot be opened while the rotor is in motion or if the internal pressure has not equalized. The machine’s central processing unit (CPU) sends a signal to lock or unlock the lid and expects a confirmation signal from a sensor (usually a Hall effect sensor or optical switch) confirming the position of the latch. Specifically, typically indicates a failure in the lid
