A little different moisture at the bottom of the storage bin is not usually a problem as long as you have full floor aeration. 11. After the run time in step 10 you are ready to adjust the moisture con- tro[...]

26 QUICK ST ART UP PROCEDURE ADJUSTING THE MOISTURE CONTROL 1. Each 5 ° on the MOISTURE CONTROL changes the output moisture by about 1%. Example: 100 ° is set, producing 16% corn out, however, 17% corn out is needed. Reduce the MOISTURE CONTROL tempera- ture by 5 ° to 95 °. This should change the moisture out to about 17%. To make the corn come[...]

46 SERVICE TROUBLE ANAL YSIS PROCEDURE A multimeter is required for some of the following check-out procedures. Before performing any tests, make certain if the dryer power supply is 1 phase, 230 volt, or 3 phase, 230 or 460 volt. • The burner circuit is 120 volts AC on all standard U. S. production models. • The control circuit to the motor st[...]

48 SERVICE Problem Display shows "FAN 1 FAILURE-NO AIRFLOW" message. Display shows "FAN 1 CANNOT START-CHECK AIR SWITCH" message. Fan motor will not start. Top auger will not start. Bottom auger will not start. Grain not moving through columns. Possible Cause The air switch contacts have opened, indicating the fan may not be tur[...]

49 SERVICE Possible Cause 1. Check the dryer for fine material buildup inside the columns. 2. Avoid leaving the dryer columns full for long periods at a time (2-3 days) while not operating the dryer or during rainy weather. 3. Empty the dryer. Keep the dryer clean! Do not allow fine material to gather in the plenum chamber. 4. It may be necessary t[...]

50 SERVICE Possible Cause 1. Check the gas pressure reading on the gauge. Problem may be due to insufficient gas regulator setting. Tempo- rarily decrease the hi-lo fire thermostat setting to verify that the thermostat will function and cause the burner to cycle. If burner will cycle at the reduced thermostat setting, it indicates that the problem [...]
