Abstract
A control system for mixing materials in a container. A screw-driven pressure plate clamps the container during mixing. Current of the clamping motor driving the screws is monitored and control circuitry allows multiple speed, multiple current draw, automatic switch-over operation of the clamping motor. Circuit components are automatically checked, and control over a mixing or clamping operation is assumed if necessary.
