Based on these data signatures, the analysis can be made to predict the future health of the equipment. Although it is difficult to achieve a sensor that can carry out self-diagnosis of all possible faults that might arise, it is often possible to make simple checks that detect many of the more common faults. If used properly, one method that's been around for years can save you valuable troubleshooting time, and that's the half-splitting method. If the fault magnitude is low, the system just needs to be able to endure the fault for an extra time until the fault is cleared by itself. Context is vital when troubleshooting equipment failure. This is also where I would have a quick look at the safety relay which has indication lights on it to indicate ready state or fault state. Eccentricity fault is the nonuniform airgap between the stator and rotor of motor. Do you need underlay for laminate flooring on concrete? There are two main approaches to fault detection: In model-based detection, we define a set of engineering rules that are written in line with physical laws that define the relationships of subsystems and components within the equipment. In short, fault detection and diagnostics play a decisive role in optimizing the maintenance regime for any piece of equipment, across its lifecycle.
