8 DRYER CONTROL P ANEL This switch turns the power ON or OFF to the moisture control ther- mostat . It lights up when the grain column temperature is below the thermostat set point. MOISTURE CONTROL SWIT CH (2) Figure 1: The grain dryer control panel with the Electronic Monitoring Control System in the upper right panel.
9 DRYER CONTROL P ANEL FAN SWIT CH (7) This is used to select the opera- tion of the load auger . In both the AUTO and MANUAL position the load auger will operate if the dryer is low on grain, and will automati- cally shut off when the dryer is full.

15 DR YER PRE ST ART CHECKS The metering roll access area. With the grain supply SHUT OFF, quickly bump the LOAD AUGER switch to MANUAL, and see if the load auger rotates clockwise as viewed from the drive end, or coun- terclockwise if the dryer is a front load model.
16 DR YER PRE ST ART CHECKS TERING ROLL SPEED should in- crease. Turning either knob coun- terclockwise will decrease the speed. Make sure the drive chain tension is properly adjusted and all sections of the metering rolls ro- tate. Turn the UNLOAD switch OFF after these checks are complete.
17 DR YER PRE ST ART CHECKS ST AGED BA TCH CHECK DR YER SHUTDOWN To shutdown the dryer, first CLOSE the FUEL SUPPLY VALVE at the tank or valve along the fuel line. If the burner is operating, let the dryer run out of fuel, and it will shutdown automatically due to loss of flame.
18 DRYER ST ART UP 1. Turn the CONTROL POWER switch to ON. 2. After the date and time appear on screen, press the RESET button. 3. Push the dryer POWER START switch. 4. OPEN the main FUEL SUPPLY VALVE on the tank if using LP gas, or OPEN the FUEL SUP PLY LINE if using natural gas.
19 DRYER ST ART UP the final moisture content is to be 15% (10% removal). Using the all heat dryeration process, the estimated drying time is 60 minutes (10 x 6). 10 . While operating the dryer adjust the METERING ROLL dials to the recommended settings.

If any of the se- lected switches are improperly positioned for staged batch dry- ing, the display will indicate the proper switch position, and will not allow the dryer to operate until the position of the switch is corrected.

22 FULL ST ART UP CHECK FILLING THE DRYER Standard electrical safety practices and codes should be used when working with a dryer. Refer to the National Electric Code Standard Handbook by the National Fire Pro- tection Association. A qualified elec- trician should make all wiring instal- lations.
23 QUICK ST ART UP PROCEDURE ST ARTING THE DRYER This start up procedure is for a cold start on wet grain for continuous flow operation. 1. Set the MAXON or FAST ACTION HAND VALVE on the incoming fuel line to the ON position. 2. Make sure the MOISTURE CONTROL switch is in the OFF position.
24 QUICK ST ART UP PROCEDURE the burner from the regulator are warm to the touch (not hot and cold). The vaporizer can be adjusted two ways: •Loosen the bolt in the hinging mechanism and swing it to a hotter or cooler position, or •Loosen the two bolts in the hinge pipe and slide the vaporizer in or out to a cooler or hotter position.
25 QUICK ST ART UP PROCEDURE will not have your grain moisture adjusted exactly where you want it, but will be a good place to start initially. A little different moisture at the bottom of the storage bin is not usually a problem as long as you have full floor aeration.
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 °.

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.
47 SERVICE Problem Display shows "MOTOR OVERLOAD" message. Display shows "BURNER 1 VAPOR HIGH TEMPERATURE" message. Display shows "BURNER 1 WARNING FLAME NOT DETECTED" message. Display shows "FAN 1 HOUSING HIGH TEMPERATURE" message.
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.
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.
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.
51 QUICK REFERENCE GUIDE ELECTRONIC MONITORING CONTROL SYSTEM Important! To activate the controller after turning on the control power, press the reset button.
