The
The metering roll speed control potentiometer in the dryer control panel is replaced by the main speed control in the Moisture/Matic. A DC voltmeter is provided to indicate the voltage applied to the metering roll motor, which will change from fast, medium or slow. The speed is selected by comparing the actual moisture of the grain being discharged from the dryer to the moisture Set Point.
As the grain moisture increases, the Moisture/Matic will slow the metering rolls down. The slower grain movement will increase the time the grain spends in the dryer, which will reduce the moisture. As the moisture nears the moisture Set Point the unit will switch from slow to main speed. As long as the grain moisture is at or near the Set Point the main speed is retained. Should the moisture start to get dryer, the unit will switch to high speed. The three speeds are adjustable to match the dryer to the grain that is being dried.
