Chapter 9: The Dry Grain
Outgoing Grain Moisture — The dry grain’s actual moisture level (%).
Outgoing Grain Temperature — The dry grain’s actual temperature (°F; °C)
Once measured, the actual average moisture of the dry grain is 15%, yet the value displayed
onscreen is 17%. Enter 15 to maintain consistency between readings.
IMPORTANT: During the unloading phase, make sure to validate the dry grain’s moisture and temperature
at least twice a day and make the necessary adjustments.
If grain is consistently discharging at a moisture content that is too high, increase the grain temperature
setpoint of the applicable control scheme. An increase of 5°F (2.78°C) removes one point of moisture.
Conversely, if grain is consistently discharging at a moisture content that is too low, decrease the grain
temperature setpoint of the applicable control scheme. A decrease of 5°F (2.78°C) adds one point of the
moisture.
Cleaning the Dry Sensor
To ensure that the dry sensor functions properly, you must check it daily and clean it once every 100 hours
of operation. Clean the dry sensor more often if the grain is too dirty.
To clean the dry sensor:
1. If the dryer is running, press Stop on the control panel, and then turn the Power switch to Off.
2. Place the safety disconnect switch in the Off position, and then turn off the dryer’s main power.
The main power that is present at the electrical cabinets turns off.
CAUTION
The Power switch controls dryer functions but does not control the power that is
present at the various electrical cabinets. Turn off the main electrical disconnect
switch to shut off power to the dryer and all electrical cabinets.
3. From the rear of the dryer, locate the dry sensor housing and the sensor cover. The dry sensor is
mounted to the back of the sensor cover.

4. Unlatch the sensor cover to access the inside of the dry sensor housing.
