13.1.4 Adjusting Shaker Speed
The shaker is designed to operate at 1,500 rpm (with 50Hz motor) or 1,800 rpm (with 60Hz motor) in either water
or oil-based mud. Motor control panels have a selector switch for Normal (Progressive Elliptical) and Capacity
(Balanced Elliptical) modes of operation. Switching between these modes affects the motion of the shaker.
THE MOTORS GENERATE A LOUD METALLIC NOISE WHEN OPERATORS SWITCH
BETWEEN DIFFERENT MODES OF OPERATION. THIS NOISE IS NORMAL AND DOES
NOT INDICATE MOTOR FAILURE.
IT IS NOT NECESSARY TO SHUTDOWN THE EQUIPMENT WHEN SWITCHING
BETWEEN THE BALANCED ELLIPTICAL AND PROGRESSIVE ELLIPTICAL MOTIONS.
