what the final moisture will be after

the grain is cooled in the bin. Though

no two farms or bins will be the same

there are some starting points. Mois-

19% after temperature correction.

If the startup steps on the previous

pages are followed the MOISTURE

CONTROL settings adjust accord-

ingly to get 130° corn out back of

dryer. On rare occasions hard dry-

ing, or immature corn may require

higher temperatures. Always use

MOISTURE TESTER to confirm

temperature reading. Use a large

sample (2.5 gallon) and an accurate

THERMOMETER (A. W. Sperry

model DT-5A digital preferred) to de-

termine actual temperature. Smaller

containers bleed off temperature be-

fore the THERMOMETER reaches

true temperature.

Bins should have:

•A full

may take too long. Do not start

longer than 2-4 hours after starting

dryer. On bins with high air flow

(above 1/2 CFM),

be cycled two hours on, two hours

off throughout the day to maintain a

thick enough hot grain layer to get

proper moisture loss in the bin.

Large dryers (1000 bu/hr and larger)

may require at least 1/2 CFM and

immediate starting of

these procedures each time you

start putting grain in the bin. Con-

tinue aeration until grain is com-

pletely cooled.

Fill each bin completely. Do not

alternate bins. Alternating would

cause different layers the moisture

in the bin. The first morning after

starting, take a cooled sample from

bin and test it. Grain will be within

.2% to .5% of final moisture at this

time. Check again 24 and 48 hours

nal decision maker as to what mois

At the bottom of the bin the air-

flow is rather high. As the bin fills

moisture will be taken out. This is

somewhat offset by the grain at the

bottom getting more hours of aera-

tion. Overdrying is common the first

year, and settings can be altered the

second year.

MAINTAINING GRAIN QUALITYMAINTAINING GRAIN QUALITY

MAINTAINING GRAIN QUALITY

MAINTAINING GRAIN QUALITYMAINTAINING GRAIN QUALITY

To properly maintain the quality of

stored grain, it is necessary to keep

the grain dry, cool and insect free.

Any of these problems can contrib-

ute to spoilage. Wet, warm grain pro-

motes insect growth as well as grain

spoilage. Cool dry grain can keep

for long periods of time if properly

maintained.

It is recommended that the grain

be kept cool (Avoid freezing. It can

reduce grain quality). Grain should be

cooled through the fall and winter,

warmed in the spring and summer.

Average grain temperature

should be above 35°F in the winter and below 65°F in the summer. Al-

ways try to keep the grain within

10°F-15°F of the average monthly

outside temperature. This means

grain may need to be aerated on

warm days during the winter to stay

above 35°F when freezing tempera-

tures are predominate. During the

summer, it may be necessary to

aerate the grain on cool nights, so the

65°F temperature is not exceeded

during the hot days of summer.

Conditions and requirements

may vary from area to area. We sug-

gest that you contact your local ag-

riculture extension office or state

agriculture university for more exact

guidelines in your area.

If the grain is to be stored for

more than one year, it has to be re-

cooled the following fall and winter,

repeating the process as long as the

grain is in storage. Frequent and

regular inspection (at least weekly

during fall and spring) is the best

prevention against grain spoilage.

*Bushels are rounded and approximate.

NR = Not recommended: Bins in the NR range, may require fan(s) of a different size to get the cool time into the acceptable range.

The hours required are based on clean grain. High moisture grain and grain containing fines or foreign material will require more time to complete the air change.

Bins requiring more than 100 hours of aeration to totally change the temperature may require continuous aeration at about 1/10th cfm per bushel or some other acceptable method.

The dryer is made of weather resis-

tant material, and is designed to re-

quire a minimum of service. How-

ever, each season we recommend

the following items be checked be-

fore the unit is used, and any dam-

aged or questionable parts replaced.

These checks will help eliminate pos-

sible failures, and assure dependable

operation of the equipment.

any loose terminal connections.

Replace any damaged or deterio-

rated wiring.

2. CHECK each

clearance. They should also be

inspected for dirt and grain dust,

especially inside the hub. Any ad-

In the event of motor failure, remove

the motor as described, and take it

to the nearest service station. An

authorized service station is the only

place that can provide possible mo-

tor warranty. Motor service and re-

pair at other places will be at own-

ers expense.

If the service station determines

motor failure is caused by faulty ma-

terial or workmanship within the war-

ranty period, repair will be covered

under the warranty. Motor failure

caused by external sources will result

in a charge to the owner for repair.

The air switch contacts have opened, indicating the fan may not be turning. The air switch may need adjustment.

The air switch contacts have closed prior to the fan starting, indicating a freewheeling blade or improper setting of air switch.

1. Check that the fan circuit breaker and the fan switch are on. Also, check for defective switch or bad wiring connections.

2. If lighted switch does not light, the air switch needs adjustment, or the bulb may be burned out.

3. Verify closing of fan motor contactor. Check voltage on load side of contactor. See appropriate power wiring circuit diagram for terminal numbers. Inspect contactor for defective points or a burned out coil.

4. Inspect connections, and check voltage applied to the motor leads in the fan heater box to determine if the motor is defective.

5. Check capacitors on single phase motors, and replace if defective. If motor starts slowly, check for low voltage during starting due to excessive voltage drop in power supply wiring.

1. Check that the top auger circuit breaker and the load auger switch are turned on.

2. If lighted switch does not light, the output power to the contactor is missing. Check connections, or if the bulb is burned out.

3. Check position of the upper auger paddle switch. It must be down to start auger.

4. Inspect for secure mounting and wiring of mercury switch in the terminal box on the top auger paddle switch shaft. Include check for a defective mercury switch.

5. Verify closing of the top auger contactor. Check voltage on load side of contactor. Inspect contactor for defective points, or a burned out coil.

6. Inspect connections, and check voltage applied to motor leads in motor junction box to determine if motor is defective.

7. Check that the mercury switch box is in the proper position.

Bottom auger will not start.

Grain not moving through columns.

* The number in the warning message designates the fan, burner or plenum where the problem is located. All areas are

numbered from the bottom up. For example, the bottom fan is number 1, and the top fan is number 2.

1. Check that the bottom auger circuit breaker is on.

2. If the lighted switch does not light, the output power to the contractor is missing. Check connections, and check to see if the bulb is burned out.

3. Check that the unload switch is on (1 or 2 speed).

4. Verify closing of bottom auger contactor; check voltage on load side of contactor.

5. If using the moisture control, check for proper setting, or defective operation of the control.

6. Check for any loose wire connections in unload auger and moisture control thermostat circuits.

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.

Possible CausePossible Cause

Possible Cause

Possible CausePossible Cause

Grain not moving through columns.

Uneven drying-Some kernels appear brown while others

are under dried.

Uneven heat exiting from dryer columns.

Burner will not fire with fan operating.

Heater switch light and gas solenoids go ON and OFF

erratically-The light blinks ON and OFF while the solenoids

"chatter".

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 to open the strike off plates in the affected columns in half inch intervals.

1. Check plenum thermostat temperature setting. Some varieties of grain are more sensitive to higher operating temperatures. It may be necessary to lower the plenum operating temperature to accommodate this.

2. Check for proper burner alignment (side to side). Vibration during shipment may have caused misalignment.

1. Burner switch must be on.

2. Check for power to ignition board.

1. The blinking light indicates the flame sensor is not detecting flame.

2. The "chattering" solenoids are caused by the loss of flame detection, and the thermostat and Fenwal ignition board trying to reestablish a flame. Check for loose wires on flame sensor; replace or repair wires or sensor.

Burner will not fire-No gas pressure with fan operating at

least 15 seconds (gas supply or fan heater malfunction).

Burner will not fire-But gauge shows gas pressure.

Burner maintains desired drying temperature-but cycles

from hi-fire to OFF (without going to lo-fire).

1. Check gas supply. Also, check gas filter and gas line for possible obstruction or closed valves. Refill tank; replace or repair parts, as required.

2. Inspect gas solenoid valves (including liquid valve on LP units) for defective coils or improper wiring. Replace valve or coil if valve will not open with proper voltage applied (120 volts).

3. Check for proper voltage. 120 volts across L1 and L2 incoming voltage to the Fenwal Ignition Board, and 115 volts outgoing across V1 and V2 to the solenoids.

1. Fenwal Ignition Board: Check board for spark by removing ignition wire from board, and holding aninsulated screwdriver against the output terminal and 1/4" away from the control box casing. There should be a strong spark. Check board wire connections. Replace the Fenwal board, if necessary.

2. Ignitor: Check that the ignitor is properly gapped to 1/8" and that it has a strong spark. Inspect the porcelain and electrodes for damage or cracking. Replace or clean if necessary.

1. Make sure the low flow control valve is not completely closed. Valve must be adjusted open to provide the proper lo-fire gas pressure listed in this manual.

2. Check lo-fire solenoid valve for proper operation.

Burner operates-But will not cycle from lo-fire to hi-fire.

1. Check the gas pressure reading on the gauge. Problem may be due to insufficient gas regulator setting. Temporarily 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 was due to insufficient heat to satisfy the original setting. Increase the gas regulator setting for additional heat output. Do not exceed the maximum pressure listed in this manual.

2. Hi-lo fire thermostat control may be defective. If the burner still will not cycle to lo-fire after decreasing the thermostat, the problem may be due to a broken or kinked thermostat sensor tube. Observe reading on the thermometer. Replace control assembly if it cannot be set to cause its switch to go to the open circuit position with normally hot air plenum temperatures.

3. If the burner continues to operate on hi-fire, check the hi-fire gas solenoid valve for a stuck or blocked open condition, or for reversed gas pipe connections. The solenoid valve must not allow gas flow when its coil is not energized.

1. Check for an excessive lo-fire gas pressure setting. Observe pressure setting shown on gauge, and compare reading with recommended low pressure settings listed in this manual. Readjust lo-fire setting on flow control valve, if necessary.

2. Check for improperly adjusted or defective hi-lo fire thermostat control. Temporarily increase the temperature setting. If the heater will still not cycle, check for problem in the control wire connections. The control wires should be connected to terminals R and B of the thermostat, so the switch will open upon temperature rise. If the burner will cycle with these two wires connected together, the thermostat is faulty.

3. Check for improperly connected or faulty hi-fire gas vapor solenoid valve. Correct any poor connections or defective wiring. If wiring appears proper, problem may be caused by a burned out valve coil or defective valve. Replace hi-fire solenoid valve, or its coil, if defective.
