Claim 9:
10. A method comprising:
performing a downhole operation in a borehole;
capturing, during the downhole operation, downhole particles and drilling mud at the surface from the borehole into a screen of at least one shaker;
shaking the screen to emit vibrations to separate the downhole particles from the drilling mud;
defining a vibration limit for a normal operating condition of the at least one shaker;
setting a vibration fault threshold based on the vibration limit for the normal operating condition;
monitoring, using at least one sensor, the vibrations over time;
in response to the vibrations exceeding the vibration fault threshold, determining there is a fault condition for the at least one shaker;
determining a measured volume of the downhole particles on the screen at a time corresponding to when the vibrations are monitored;
in response to determining a difference between the measured volume and a projected volume of anticipated downhole particles exceeds a volume error threshold and in response to the vibrations not exceeding the vibration fault threshold, outputting, determining that a downhole condition occurring based on the measured volume;
monitoring number of revolutions per unit of time of a motor of the at least one shaker causing the shaking; and
in response to determining the number of revolutions per unit of time exceed a revolution threshold and in response to the vibrations exceeding the vibration fault threshold, determining that the fault condition comprises a fault in the motor.
