How the Advanced Moisture Control Works
1. Wet and dry moisture and grain temperature are continually monitored.
2. Control action is mainly based on the dry sensor.
3. Grain flow is increased or decreased to maintain the required dry moisture.
4. The wet sensor and the column grain temperature sensor are intended to detect moisture spikes
coming into the dryer so that the moisture controller can react ahead of time. If the wet sensor detects
a jump of moisture coming into the dryer, the controller will slow down the unload speed immediately.
This process is gradual, to prevent over-drying.
5. MANUAL control is use at the start of drying to allow the controller to gather sufficient information to
adequately control.
IMPORTANT: Once drying has commenced DO NOT make frequent adjustments to drying parameters.
This will cause control instabilities and result in over or under drying. Allow the controller to
manage the dryer.
