1. A method for automatically controlling acceleration of a basket of a vibratory separator, the basket having at least one screen for screening material,the vibratory separator comprising:

  • screen supports removably secured to the screen with an electro-magnetic clamp apparatus,motor apparatus connected to the basket for vibrating the basket and the screen,the motor apparatus applying force to the basket to accelerate the basket,sensor apparatus connected to the basket for sensing basket acceleration,control apparatus for receiving signals from the sensor apparatus and for introducing a material to the vibratory separator,the method comprising,controlling the motor apparatus,sensing with the sensor apparatus acceleration of the basket and providing a signal indicative thereof to the control apparatus, and,with the control apparatus, further controlling the motor apparatus to automatically adjust acceleration of the basket, the method further comprising,clamping the screen supports to the screen by energizing the electro-magnetic clamp apparatus to a magnetized state and maintaining it in a magnetized state with a single pulse signal from a controller device and,with a second, later single pulse from the controller device, setting the electro-magnetic clamp apparatus to an un-magnetized state, releasing the screens;

    wherein the clamp remains in the un-magnetized state indefinitely until it is once again re-energized by another single electric pulse from the controller device.
