TruDry Settings

The second button under the Service Page is the TruDry Settings button. This page allows for adjustments to be made to the variables that control how the TruDry mode operates.

Here the current Mid-Grain Temperature and Discharge Speed are displayed along with the Mid-Grain Temperature set point which can be adjusted. However, the main purpose of this page is to set the Proportional, Integral, and Derivative parameters of the TruDry PID control loop. Please note that changes to these parameters will drastically impact the operation of the dryer when running in TruDry mode and any settings change should only be done when instructed by Mathews Company service personnel.

The default values for the Proportional, Integral, and Derivative parameters are recommended to be used. If fine-tune adjustments need to be made, the following explains the impact of each parameter:

Proportional

The Proportional parameter determines the gain of the control loop based on the difference between the setpoint and the actual value. Adjustment of this parameter will increase or decrease the gain when a difference between the setpoint and actual value is established.

Integral

The Integral parameter determines the responsiveness of the control loop from a time standpoint. Adjustment of this parameter will cause the control loop to become more or less responsive.

Derivative

The Integral parameter determines the amount of dampening that the control loop will exhibit. Adjustment of this parameter will increase or decrease the amount of overshoot that is observed by the control loop.
