DRYER START 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. See the chart on page 00.

11.To move grain through the dryer

turn the MOISTURE CONTROL switch to ON. The switch will light up.

Note: When the UNLOAD switch is in the 2 SPEED position, and the

MOISTURE CONTROL THERMO- STAT switch is OFF, the speed of the metering rolls can be manually adjusted by turning the HIGH SPEED METERING ROLL dial. Turning the dial clockwise will IN- CREASE the grain discharge rate, counterclockwise will DECREASE the discharge rate. (The numbers on the speed dials indicate the percent- age of full speed.)

12.At the end of the start-up pe- riod, start the flow of grain out of the dryer. Turn the UNLOAD switch to the 2 SPEED posi- tion. The bottom auger and metering roll will immediately start, and the unload switch will light. If additional grain han- dling equipment is utilizing the unload auxiliary overload sup- plied with the dryer, this equip- ment will also immediately start.

13.To shut the dryer down, CLOSE the FUEL SUPPLY VALVE at the fuel tank or fuel source. Let the dryer run until the fuel sup- ply lines drain, and the dryer automatically shuts down due to loss of flame. CLOSE the FUEL valve at the dryer. Press the DRYER POWER STOP button. Turn OFF the dryer's SAFETY DISCONNECT handle. Turn OFF the MAIN POWER supply to the dryer.

14.In case of emergency push the

dryer STOP button. The fan, burner and all augers will stop immediately.

Note: The Electronic Monitoring Control System can be used to au- tomatically start the dryer. Place all the control panel SELECTOR switches in the PROPER POSI- TION, and OPEN the electric FUEL SHUT OFF valve before PRESSING the DRYER POWER START button. The controller will start all dryer com- ponents in their proper order.

STAGED BATCH

OPERATION

1.Turn the CONTROL POWER switch to ON.

2.Make sure the DRYING MODE switch is turned to STAGED BATCH.

3.After the date and time appear, PRESS the RESET button.

4.OPEN the main FUEL SUPPLY VALVE on the tank if using LP

gas or the valve in the FUEL SUPPLY LINE if using natural gas. Turn ON the ELECTRIC SHUT OFF, Maxon valve (if so equipped), or OPEN the manual SHUT OFF valve to allow fuel flow to the dryer.

5.The dryer should already be filled with grain. Turn the LOAD AUGER switch to AUTO. In both the auto and manual position, the grain level switch will auto- matically keep the dryer full of grain. In the auto position, the dryer will shut down after the preset time period on the OUT OF GRAIN TIMER, or if the grain flow to the dryer is inter- rupted.

6.Turn the FAN switch to AUTO. The fan will start, and the switch will light up when airflow is de- tected.

7.Start the burner by turning the HEATER switch to AUTO. Af- ter purging for approximately 10 seconds the burner will fire, and the heater switch will light up indicating that the flame sensing circuit is sensing burner flame. For information concerning burner adjustment see the pre start section of this manual.

8.To properly set the correct dry, cool and unload time for various moisture content grains. See the chart on page 00.
