1. Introduction
Dryer Operation
Thank you for choosing a GSI/FFI Vision Series Grain Dryers. These units are among the finest
grain dryers ever built; designed to give the excellent operating performance and reliable service for
many years.
This manual describes the installation and operation for all standard production model dryers. These
dryers are available with liquid propane or natural gas fuel supply, 1 phase 230 volt, 3 phase 230 volt,
460 volt, or 575 volt (60 Hz) electrical power.
Our foremost concern is your safety and the safety of others associated with this equipment. We want to
keep you as a customer. This manual is to help you understand safe operating procedures and some
problems which may be encountered by the operator and other personnel.
As owner and/or operator, it is your responsibility to know what requirements, hazards and precautions
exist, and to inform all personnel associated with the equipment or in the area. Safety precautions may be
required from the personnel. Avoid any alterations to the equipment. Such alterations may p roduce a very
dangerous situation where SERIOUS INJURY or DEATH may occur.
This equipment shall be installed in accordance with the current installation codes and applicable
regulations which should be carefully followed in all cases. Authorities having jurisdiction should be
consulted before installations are made.
Operating Precautions
READ THESE INSTRUCTIONS BEFORE INSTALLATION AND OPERATION
SAVE FOR FUTURE REFERENCE
1. Read and understand the operating manual before attempting to operate the unit.
2. Keep ALL guards, safety decals, and safety devices in place. NEVER operate dryer while guards

1. Recommended towing hitch height is 14"-17''. (See Figure 4A.)
Figure 4A Use a 14"-17'' Towing Hitch Height and a Safety Chain
2. Hitch bolt must be at least 3/4" in diameter and securely fastened with a locking nut, so it will not
come out during travel and the hitch will not bend. (See Figure 4B.)
3. Be sure to minimize vertical hitch play with washers. (See Figure 4B.)
Figure 4B A 3/4'' Hitch Bolt and Washers Fastened with a Locking Nut
at the Bottom of the Hitch
4. Always use a safety chain. (See Figure 4A.)
5. Dryer must be towed empty and in accordance with applicable state or provincial regulations.
NOTE: NEVER tow dryer with grain or any other material inside of it.
6. Recommended tire pressure is 55-60 PSI (cold).
7. Maximum towing speed is 45 miles per hour or the speed limit, whichever is lower.
8. After the first 50 miles and every 200 miles thereafter, check the following:
a. Dryer wheel hub and spindle temperature immediately after stopping. Temperature should not
exceed 150°F. It may be hot to touch, but not melting lubricant.
b. Wheel lug nuts. They are factory torqued at 115 to 120 ft. lbs. Retighten, if required.
14 PNEG-1702 ETL Listed GSI/FFI Portable Dryer Manual
4. Installation
Location of the Dryer
When considering the exact location of the dryer, also consider the wet grain supply and dry grain
discharge, as well as the location of storage bins and other grain handling equipment. Do not install
the dryer inside a building or in any other area where not allowed by electrical codes, fuel installation
regulations and/or insurance requirements. Maintain a minimum distance of at least 3' from other
structures, otherwise air flow problems may occur. Do not operate in an area where combustible materials
can be drawn into the fans or where load and unload augers can come in contact with power lines.
Foundation
A reinforced concrete pad or similar permanent foundation is recommended for dryer stability.
See Pages 22 and 23 for details.
Supporting the Dryer
The wheels are to be used for transporting the dryer only when empty. Before loading any grain into the
dryer, the frame of the unit on each side must be supported. Place concrete blocks on each side, every
6' of the frame, as well as at the hitch mount location with the hitch removed. The blocks must be able to
support the dryer as well as the additional weight of the grain when full. Use shims to provide uniform, level
support for all blocks. The dryer should be at least 16'' off the pad to allow for clean out and the use of
auxiliary grain handling equipment. The hitch tongue should be removed, but the hitch assembly and the
fan support must be left on during operation; they are not part of the transport tie down assembly.
NOTE: Use a minimum of one support per each 6' of basket length on each side.
Anchor Points
Anchor points may be cast into the concrete slab or the dryer may be tied down by cables and turnbuckles
to anchors installed at the edge of the slab. This helps prevent overturn or lateral movement by wind or
other forces.
Wet/Dry Grain
Wet Grain Supply
A wet grain holding bin provides gravity flow to the dryer or loading conveyor. This conveyor may
be electrically connected to the power circuit provided in the main control box. Initially, the dryer will fill
completely. During drying, the top auger will start and stop as required depending upon the dry grain
discharge rate and grain shrinkage to maintain the dryer fill. If the dryer does not fill within the pre-set
time on the out of grain timer (See Vision Manual for instructions on setting this timer), the dryer
will shutdown.
Dry Grain Removal
The dry grain is normally discharged out of the rear end of the dryer. Front discharge is an optional feature.
A take away system needs to be provided to remove grain from the drying system. This conveyor may be
electrically connected to the power circuit provided in the main control box.

Electrical Power Supply
Power Supply
An adequate power supply and proper wiring are important factors for maximum performance and long
life of the dryer. Electrical service must be adequate to prevent low voltage da mage to motors and control
circuits. (See Chapter 5 on Pages 24-36.) Power supply for 1 phase models must include a neutral wire.
Transformers and Wiring Voltage Drop
Advise the service representative of the local power supplier that an additional load will be placed on the
line. Check the KVA rating of transformers, considering total horsepower (HP) load. The power supply
wiring, main switch equipment and transformers must provide adequate motor starting and operating
voltage. Voltage drop during motor starting should not exceed 14% of normal voltage. After motor
is running at full speed, it should be within 8% of normal voltage. Check electrical load information
(See Chapter 5 on Pages 24-36)
Power Supply Disconnect
All dryers are equipped with a power disconnect switch in the power box to permit total power shutdown
before opening the power box door, as required for inspection and service. The power disconnect switch
is located on the power box door for quick shutdown.
for HP ratings and maximum amp loads.
Machine to Earth Grounding
A Machine to Earth Ground Rod must be installed at the dryer. Place the ground rod that co mes standard
within 8' of the dryer and attach it to the dryer control panel with at least a #6 solid, bare, copper ground
wire and the clamp provided. The grounding rod located at the power pole will not provide adequate
grounding for the dryer. Proper grounding will provide additional safety in case of any short and will ensure
long life of all circuit boards, the SCR drive and the ignition system. The ground rod must be in accordance
with local requirements.
All wiring to be done in accordance with the Canadian Electrical Code.

4. Installation
Figure 4C Installation of a ground rod (standard with dryer purchase) specifically
for the grain dryer is necessary for safety and equipment preservation.
Proper Installation of Ground Rod
The rod should not be driven into dry ground. Follow these instructions for proper installation.
1. Dig a hole large enough to hold one to two (2) gallons of water.
2. Fill hole with water.
3. Insert rod through water and “jab” it into the ground.
4. Continue “jabbing” the rod up and down. This allows the water to work its way into the ground,
allowing it to be completely inserted into the ground. This method of installation also assures good
contact with the surrounding soil, thereby making a proper ground.
5. Connect the bare, copper ground wire to the rod with the proper clamp.
6. Connect ground wire to control panel with the ground lug provided in the control box.
7. Ground wire must not have any breaks or splices. Do not use insulated wire for grounding ap plications.
Connecting Auxiliary Conveyors
The auxiliary load and auxiliary unload augers or conveyors can be wired directly to the dryer. Electrical
load information in Chapter 5 on Pages 24-36 shows the maximum horsepower and amps of auxiliaries
that can be wired to the dryer. If an auxiliary motor is larger than recommended, it must be powered from
a source outside the dryer and must use a separate contactor and overload protection device for each
motor. However, the operation of the auxiliaries can be performed by the control panel.

Fuel
Liquid Propane (LP)
Liquid Draw
The dryers have internal vaporizers and are designed to operate on liquid draw from the supply tank. The
tank should be 1000 gallons or larger and should not have a regulator mounted to it. The connection to
the dryer should be with a flexible hose designed for LP gas, See Chart on Page 19 for proper size.
Consult your LP gas dealer for proper fittings, connection hose and safety controls required to meet local
standards and to conform with National Fire Protection Association standards. The piping train on the
dryer includes strainer, pressure relief valve, electronic safety shut off valve (on some models) and a
pressure regulator between the vaporizer and burner.
Ammonia Tanks
Do not use tanks which have previously been used for ammonia or fertilizer solutions. These substances
are extremely corrosive and will damage fuel supply and burner parts.
Oil or Water in Tanks
With liquid draw from the supply tank, any water or oil present in the tank may freeze in the pipe train or
controls causing damage. To make sure the tank is free of moisture, it can be purged with methanol.
Avoid tanks which may contain an accumulation of oil or heavy hydrocarbon from long use on a vapor
withdrawal system.

WARNING
Dip switch number eight (#8) must be turned back to the OFF position after this
test is complete or no air testing will occur.
Fan Switch
Bump the Fan switch and observe the fan rotation. The fan should run counterclockwise. Sometimes on
3 phase models all motors on the dryer will run backwards. They can easily be reversed by interchanging
two of three power supply wires. Reverse the two (2) outside wires, L1 and L3 and leave the middle one
in the same position.
NOTE: If the dryer is empty, the burner does not operate. The fans cannot create enough static pressure
to engage the Air switch. You will receive a “no airflow” message. To start the dryer when it is low
on grain, the Airflow switches must be turned OFF. Switching Dip Switch number eight (#8), on the
back of the computer control board, to ON turns the Air Switch OFF.
Burner Safety
To check the burner safety function, make sure the main gas valve is OFF. Turn the Fan switch ON and
allow the fan to start. Then, turn the Heater switch ON. The dryer will shutdown after 20 seconds. The
safety message, “loss of flame” will appear.
Burner Test Fire
The following test should be done with grain in the d ryer. If no g rain is pre sent, set approximate pr essure
settings and fine tune when grain arrives. Test fire the burner by starting the fan and then turn the
Burner switch to ON with the fuel supply turned ON. The heater should ignite after a short purge delay of
approximately 10 seconds. Gas pressure should be shown on the gauge. At this time, set the high-fire and
low-fire pressure settings. Use the pressure regulator (See Figure 6D on Page 44) for high-fire and the
needle valve located in the side of the cycle solenoid (low-fire) valve (See Figure 6D on Page 44) for
low-fire. The burner should cycle between high-fire and low-fire, approximately 2 or 3 times per minute.
Approximate settings s hould be:
LP Gas Natural Gas
High-Fire 6-15 lbs. High-Fire 6-10 lbs.
Low-Fire 2-6 lbs. Low-Fire 1-3 lbs.
If the burner remains on high-fire and does not cycle, increase t he regula tor setting, in o rder to rea ch the
thermostat setting. If the burner remains in low-fire and does not cycle, slightly decrease gas pressure with
the low-fire solenoid needle valve. If the gas pressure is decreased too much, a popping or fluttering
sound will be heard. Be sure to adjust the low pressure needle valve anytime the high pressure regulator
is adjusted.

Load Auger
With the grain supply shut off, quickly flip the Load Auger switch to MANUAL and see if the load auger
rotates clockwise as viewed from the drive end, or counterclockwise if the dryer is a front load model. If
the wet grain supply auxiliary is wired to the dryer, it should also rotate in the correct direction at this time.
Turn the Load Auger switch to the AUTO position. The top auger and wet grain supply auxiliary should run
for 8 minutes. The dryer will then shutdown and the safety shutdown message: Out of grain will display.
Press the Stop button to reset the panel, then press the Start button.
Unload Auto Operation
To check Auto operation, place the Unload switch in the AUTO position. Push then turn the meter roll dial
to a setting of 500 and touch ACCEPT/EXIT to start the meter roll rotation. The bottom auger should rotate
counterclockwise as viewed from the drive end. The meter roll drive motor should rotate clockwise as
viewed from the drive end of the gearbox. If the dry grain take away auxilia ry is wired to the dryer, it should
start and rotate in the proper direction.
Unload Manual Operation
To check Manual operation, move the Unload switch in the MANUAL position. Push then turn the meter
roll dial to a setting of 500 and touch ACCEPT/EXIT to start the meter roll rotation. The bottom auger
should rotate counterclockwise as viewed from the drive end. The meter roll drive motor should rotate
clockwise as viewed from the drive end of the gearbox. If the dry grain take away auxiliary is wired to the
dryer, it should start and rotate in the proper direction.
Meter Roll Operation
Meter Roll Operation 4" (GSI)
When the meter rolls are set to maximum (1000), the meter roll speed should be 17.5 RPM for 8'' (20 cm)
discharge augers. Make sure the drive chain tension is properly adjusted and all sections of the meter rolls
rotate. Turn the Unload switch OFF after these checks are complete. The bottom auger will continue to
run for 60 seconds (the default clean out delay setting) after the switch is turned OFF to allow for clean out.
Meter Roll Operation 7" (FFI)
To check the meter roll operation turn the knob clockwise and the meter roll speed should increase.
Turning the knob counterclockwise will decrease the speed. When the meter rolls are set to maximum
(1000), the meter roll speed should be 4.3 RPM for 8" (20 cm) discharge augers. Make sure the drive chain
tension is properly adjusted and all sections of the meter rolls rotate. Turn the Unload switch OFF after
these checks are complete. The bottom auger will continue to run for 60 second s (default clean out delay
setting) after the switch is turned OFF to allow for clean out.
NOTE: Due to the nature of the DC drive motor used on the meter rolls, it is possible for the brushes inside
the motor to become corroded if the dryer has not been operated for several months. This will
cause the meter rolls not to function. To fix this problem, use a rubber mallet or a piece of wood t o
tap the DC drive motor. The shock is usually sufficient to re-start the motor and metering rolls. You
should not have any more problems with this during the rest of the drying season.
PNEG-1702 ETL Listed GSI/FFI Portable Dryer Manual 47
7. Vision Test Firing
All power should be switched OFF and locked out before attempting to reverse
the connections.
Fan Switches
Briefly turn each Fan switch to ON and observe the fan rotation. The fan should run counterclockwise.
Sometimes on 3 phase models, all motors run backwards. They can easily be reversed by interchanging
two of the three power supply wires. Reverse the two (2) outside wires, L1 and L3 and leave the middle
one in the same position.
WARNING
NOTE: The bottom fan on the dryer is always referred to as fan 1.
Burner Safety
To check the burner safety function, first make sure the main gas valve is OFF. Turn the Fan switch ON
and allow the fan to start. Turn the Heater switch ON for that fan. The dryer will shutdown after
20 seconds. The safety message, “Ignition Failure Fan #” will appear. Reset the dryer and repeat for the
other fan/heater(s).
Burner Test Fire
To perform this test, the dryer must be full of grain, otherwise the air switch will need to be disabled,
if the dryer is empty. To disable, touch the Setup button at the bottom of the Default Operation Screen.
When the Setup Screen appears touch the Diagnostics button to display the system diagnostics. To
disable the air switch select the Disable Testing button in the air switch box of the System Diagnostics
Screen. The vision computer will then display a prompt asking if you wish to disable the air switch. Choose
yes to continue. Once the air switches are disable the Fan switches on the switch panel will illuminate and
the fan/heaters on the display animation will change to blue indicating that “airflow” is simulated.
There is only a 5 minutes period after the dryer is turned ON that the air switches can be disabled. After
that time the Air switches cannot be disabled and any Air switches that are disabled will return to the
enabled state causing an airflow shutdown if the d ryer is empty. To restart the 5 minutes testing period the
dryer must be shutdown and restarted. The 5 minutes testing period starts when the Control Power switch
is turned ON.
Test fire each burner by starting the fan. Turn on the fuel supply then, turn the Burner switch to ON and
the burner should ignite after a short purge delay of approximately 10 seconds. Gas pressure should be
shown on the gauge. At this time adjust the plenum setpoint to 200°F (93°C), causing the burner to operate
on high-fire. Observe the gas pressure on the gauge and lower the plenum setpoint until it causes the
burner to cycle into low-fire. When the plenum temperature setpoint is met, the gas pressure should show
a noticeable drop, indicating that the cycle solenoid is closed and the burner is being supplied with less
gas through the cycle solenoid bypass port. At this time set the high-fire and low-fire pressure settings.
Use the pressure regulator for high-fire and the adjustment screw on the cycle solenoid for low-fire. The
computer should cycle the burners between high and low, approximately 1 to 3 times per minute.
Use only the amount of pressure required to obtain the desired temperature.

This start-up procedure is for a cold start on wet grain for continuous flow operation.
1. Turn ON the LP gas tank and any other manual gas valve at this time. Set the MAXON or FAST
ACTION HAND VALVE, if so equipped, on the incoming fuel line to the ON position.
2. Make sure the Moisture Control switch is in the OFF position.
3. Turn the Fan switch to the ON position.
4. Adjust the Air Pressure switch if necessary.
5. Turn the Heater switch to the ON position. The heater will purge for about 10 seconds then ignite. If
flame is detected the dryer will run, if not, a “loss of flame” error will occur. If this happens, check ga s
supply and all valves in the fuel line to make sure they are ON and attempt again.

Adjusting the Temperature
1. Press the Program (Temperatures) button until the “carrot” is above the timer to be modified.
2. Use the UP and DOWN arrow keys to change the present temperature to the desired setting. The
new temperature is automatically accepted.
3. Keep pressing the Program (Temperatures) button until the carrot disappears or press the Mode
Select button once to exit.
4. On LP and NG gas models, adjust the PRESSURE REGULATOR (high-fire) on the burner fuel
line, so that burner will reach the thermostat setting and switch to low-fire.
The approximate settings should be:
LP Gas Natural Gas
High-Fire 6-15 lbs. High-Fire 6-10 lbs.
Low-Fire 2-6 lbs. Low-Fire 1-3 lbs.
Do not set the low-fire pressure so low that a popping or fluttering sound is heard in the heater. If
popping or fluttering sound are heard, increase the pressure until the sound goes away.
On LP and NG gas models adjust the needle valve on the cycle solenoid (low-fire valve) so that the
burner maintains flame then switches back to high-fire.
5. Adjust the burner pressure so that the burner CYCLES 2 to 3 times per minute (approximately 15 to 20
seconds on HIGH and approximately 5-8 seconds on LOW). Increasing the gas pressure with the gas
regulator increases the cycling rate and lowering it decreases the rate. This is the primary way to
change the cycling rate.
Decreasing the low pressure setting with the needle valve will also increase the rate while increasing
that pressure will decrease the rate.
6. On LP gas models adjust the vaporizer so the fuel pipes going to the burner from the regulator are
warm to the touch (not hot and cold).
The vaporizer can be adjusted two (2) ways. First, by loosening the bolt in the hinging mechanism and
swinging it to a hotter or cooler position. Second, by loosening the two (2) bolts in the hinge pipe and
sliding the vaporizer in or out to a cooler or hotter position. Either one or both methods may need to be
used to get the vaporizer to the proper temperatu re, but the first almost always gives adequate adjustment.
Natural gas does not use a vaporizer.

8. Competitor Dryer Operation
Full Heat Continuous Flow Operation
1. Refer to PNEG-1650/PNEG-1651 DRYER START-UP. (CONTINUOUS FLOW METER ROLL
SETTINGS - FULL HEAT.) There are settings for initial moisture, moisture removed, approximate dry
time, 1 Speed, 2 Speed low and 2 Speed high. Select the line that indicates the initial moisture.
These are the settings referred to throughout this start-up procedure.
2. Make sure the Unload switch is OFF.
3. Make sure the Moisture Control switch is OFF.
4. If the dryer is stopped, press the Start switch to lock in the control circuit.
5. Turn the Fan and Burner switches to the “ON” position to run fans and burners. Be sure to adjust
the plenum temperature to 180°F for all burners. Run the fans and burners for about 10% longer
than the approximate dry time (refer to PNEG-1650/PNEG-1651) for the incoming moisture.
Example: Ten points removal from the chart is 54 minutes, plus 5.4 minutes (10%) equals
59.4 minutes (round up to 60).
6. Increase the drying temperature to a maximum of 210°F (corn) for single fan dryers. For multiple fan
dryers adjust the top burner to a maximum of 230°F (corn) and stage the temperature of the lower
burners down 30° per burner. Example: 3 fan dryer Top burner: 23 0°, Middle burner: 200°, Bottom
burner: 170°.
7. After the initial fan and burner run time, set the Unload switch to “1 Speed” and set the high speed
meter roll potentiometer to the setting for 1 Speed (refer to PNEG-1650/PNEG-1651). Meter rolls
should start and grain will begin to flow from discharge of dryer. Run time for this step should be
the same as from Step 5 above. DO NOT TO ADJUST THE DRYER DURING THIS PERIOD.
The grain discharging towards the end of this period will be over dried, but it is necessary so that the
corn moisture is staged properly and evenly in the dryer.
8. Turn the Moisture Control switch to “ON”. Set the moisture control (grain) temperature to 100°F.
9. Turn the Unload switch to “2 Speed”. Find the “2 Speed High” and “2 Speed Low” meter roll settings
(refer to PNEG-1650/PNEG-1651) and set meter roll potentiometers accordingly. Allow the dryer to
run for the time established in Step 5 and then sample the grain. If the dryer has been cycling
regularly from high to low and the grain is not coming out to moisture desired, then adjust the
moisture control (grain) temperature up or down 5° per point of moisture. Example: Moisture control
is set to 100°, desired moisture is 15%, sampled moisture is 17%. Adjust moisture control to 110°.
EVERY TIME AN ADJUSTMENT IS MADE IT IS IMPERATIVE THAT THE DRYER IS ALLOWED
TO RUN FOR THE ESTABLISHED TIME IN ORDER FOR CHANGES TO TAKE AFFECT. Repeat
this process as necessary until desired moisture content is being discharged from dryer.
10. After the run time in Step 9, the moisture control and the meter roll spee ds can be adjusted if required.
Each time an adjustment to the moisture control is made, it will take approximately the time as shown
in the example in Step 5 to see the results of this adjustment.
PNEG-1702 ETL Listed GSI/FFI Portable Dryer Manual 55
8. Competitor Dryer Operation
Adjusting the Moisture Control
1. 5° on the moisture control will change the output moisture by about 1%. Example: With 100° set, the
result is 16% corn but 17% corn is desired. Reduce the moisture control setpoint temperature by 5°
to 95°. This should change the moisture out to about 17%. If you want the corn to come out dryer,
raise the temperature on the moisture control setpoint.
2. Four (4) sensors are averaged together for sensing moisture control temperature, one on each side
of the dryer in the front and one on each side of the dryer in the back. They are locat ed about 1/3 of
the way up the grain column from the bottom and in from the side about 4''.
3. Grain temperatures can be monitored by pressing the Mode Select button.
4. The moisture control should stay on HIGH about 50% to 90% of the time. There is a broad range that
will work. It should switch from low to high and back again to main tain the desired moisture. A control
that does not switch will not maintain an evenly dried grain moisture when the incoming wet grain
moisture varies.
5. If the Metering Roll switches to LOW and stays there for long periods of time, both the high a nd low
speed potentiometers should be slowed down 2% (20 points) and monitored for further adjustment.
6. If the Metering Roll switches to HIGH and stays on HIGH more then 90% of the time, increase the
speed on both potentiometers 2% (20 points) and monitor for further adjustment.
7. When adjusting the METER ROLL SPEEDS it is better not to change the speed more than 20 points
(2%) at a time.
8. Anytime a change is made, wait the approximate dry time for t hat moisture grain from the chart (refer
to PNEG-1650/PNEG-1651) before checking the grain moisture level and making another change
if necessary.

9. Vision/Dri-Tek Dryer Operation
Dryer Start-Up and Operation Full Heat Drying
Full Heat Operation
With this type of drying, the grain is discharged hot, with no cooling. Drying capacity is substantially higher
with full heat than the dry and cool process.
Final Moisture
The cooling process usually removes 1% to 3% moisture, so hot shelled corn is removed from the dryer
at about 17% moisture if the final desired moisture content is 15%.
Drying Temperatures
Shelled Corn
For shelled corn with an initial moisture content of 25%-30%, the recommended maximum drying
temperature is 220°F-240°F (104°C-116°C) for the top fan and 170°F-190°F (77°C-88°C) for the
bottom fan.
Small Grain
For drying small grain (wheat, oats, milo), 150°F (66°C) is suggested.
Soybeans
Drying temperatures are critical in drying rice and soybeans. A temperature of 130°F (54°C) is
recommended to keep grain temperature low.
Drying Efficiency
The general rule for obtaining the highest drying efficiency is to use the highest possible drying
temperatures that does not adversely affect grain quality.
Dryer Shutdown
Cooling Hot Grain
If the dryer is to be shutdown while filled with grain, it is recommended that hot grain be cooled for
10 to 15 minutes, especially in cold weather, to prevent water vapor condensation and possible freezing
of such condensate following shutdown.

Step 14
turn the Unload Auger switch to MANUAL and set the meter roll speed,
(manual speed). Remember that Manual is a true manual operation, with no moisture control. The
meter rolls will run at the speed that you select using the meter roll speed encoder. To do this, pre ss
on the meter roll adjustment knob. When the “Modify Meter Roll Setpoints” window appears turn the
meter roll adjustment knob until the speed indicator is set to the speed suggested for 1 Speed, then
touch the Accept/Exit button to set this value into the computer. Grain should begin to run at this time.
Run time for this is about 10% longer than the (approximate drying time) required for the moisture you
are trying to dry. This allows the moisture in the dryer to reach an even gradient top to bottom without
having any highs or lows in it. It will however, over dry some of the grain.
Figure 9B
16. Increase the drying temperature to 190°F for single fans or for multiple fan dryers, set the
heat chambers 30° to 60° apart. Hottest at the top and the coolest at the bottom. See setting the
temperatures in Vision Manual.
17. DO NOT ADJUST THE DRYER FOR MOISTURE DURING THIS PROCESS OR THE DRYER WILL

window appears, set the upper temperature to about 130°F. Let the dryer run on these settings for
at least 30-40 minutes before making further adjustments to the moisture control or meter roll
settings. While these settings does not achieve grain moisture exactly as desired, they will serve as
a good starting point for adjusting the settings to reach the desired results. A slightly different
moisture at the bottom of the storage bin is not usually a problem if full floor aeration is present.
21. After the run time in Step 20, adjust the moisture control and the meter roll speeds if required.
Each time an adjustment is made to the moisture control, it will take approximately the amount time
shown in PNEG-1650/PNEG-1651 to see the results of this adjustment. For every 5° change in

So far only the 2 Speed meter roll option has been discussed. The 2 Speed meter roll option works well if
the grain entering the dryer has nearly the same moisture content. However, if the moisture content
of the grain entering the dryer varies greatly, then the 5 Speed option may be more beneficial. The
5 Speed option allows the user to set an inner and outer limit for the high and low meter roll settings as
well as an inner and outer limit for the moisture control temperature setting. When se tting up the 5 Speed

21. The dryer will immediately switch to the 5 Speed moisture control. If you press the meter roll knob,
you will now notice that there is one meter roll speed to adjust.
How the Moisture Control Works
The controller continuously monitors the moisture coming in and out of the dryer, as well as the column
grain temperature at the end of the drying section. Howeve r, the co ntrol act ion is based on the sensor at
the outlet of the dryer. If the moisture coming out o f the d ryer is no t at the target, the controlle r will spe ed
up or slow down the unload accordingly. How the meter rolls react depends o n the setpoint and the actual
moisture coming out of the dryer. As long as the outgoing moisture is three-tenths above or below the
setpoint, the meter rolls run on the middle speed. Once the moisture begins to drift from the setpoint by
over three-tenths either above or below the setpoint, the speed will automatically switch between middle
and low, or middle and high speed. This is a very fast response and will bring grain back towards the
setpoint quickly.
The manual speed setting is responsible for the first pass of drying because the controller does not yet have
enough information about the grain in the dryer. Set the manual unloading speed as close as it should be
for the grain currently in the dryer before switching to moisture control mode. The manual speed setting
does not need to be adjusted after the moisture control is activated.

11. Service
Before starting any repairs or maintenance on the dryer, observe the following safety steps:
1. Isolate the whole system from the electrical supply by switching OFF the power isolator and
locking it.
2. Isolate the dryer from the gas supply by shutting OFF the main gas valve. (If necessary, lock
the valve.)
3. Keep the keys in your possession.
4. Augers and their drives may be under some degree of tension. Avoid touching these parts
with the hands until you are sure that they are free.
5. Do not reconnect the power supply until all work is completed and all guards are correctly refitted.
Seasonal Inspection/Service
The dryer is made of weather-resistant material and is designed to require minimum service. However,
each season we recommend the following items be checked before the unit is used and any d amaged or
questionable parts replaced. These checks will help eliminate possible failures and assure dependable
operation of the equipment.
1. Shut off electrical power. Open the power box to control inspect for moisture, rodent damage or
accumulated foreign material. Remove any foreign material present. Inspect and tighten any loose
terminal connections. Replace any damaged or deteriorated wiring.
2. Check each blade for freedom of rotation and uniform tip clearance . The y shou ld also be inspected
for dirt and grain dust, especially inside the hub. Any additional weight can seriously affect the
balance and result in harmful vibrations and a short bearing life.
3. Check each blade for free play. Any side play is an indication of defective motor bearings, which
should be replaced to prevent a complete motor failure. Make sure motor mount bolts are tight.
4. Motor bearings should be lubricated periodically, depending on operating conditions. Under normal
usage it is desirable to have the motor cleaned, checked and bearings repacked by an authorized
service station every two to three seasons. If the unit is operated continuously through most of the
year, this service should be performed each year.
5. Remove and clean the gas line strainers. Make certain gas valves are closed and that gas is purged
from the system before attempting to disassemble anything.
6. Inspect the collector plate at the top of the burner casting and the burner cup for any accumulation
of foreign material and clean if required. Foreign material in the burner cup or casting will not burn
out and will impair burner operation.
7. If required, inspect the ignitor plugs and clean the electrodes. Use an ignition point file to remove
carbon and rust between the electrode surfaces. The ignitor gap should be about 1/4" (3 mm).
8. Inspect flame sensors for possible damage or poor connections. Flame sensor wires must be in
good condition.
9. Inspect and manually rotate the top auger paddle assembly. The paddle unit must rotate freely
without any indication of sticking or binding.
10. Inspect the top auger and bottom auger drive lines for proper adjustment and condition. Readjust line
tension as required.
82 PNEG-1702 ETL Listed GSI/FFI Portable Dryer Manual
11. Service
11. Operate dryer clean out levers and check the clean out hatch mechanism for proper operation. With
the hatch open, inspect and remove any accumulation of dirt, fines and foreign material from the
bottom auger trough area.
NOTE: Do not allow high moisture material to collect within the trough area. It may adversely affect
metal parts.
Dryers with 7" meter rolls will need the meter roll pans dumped or cleared. Remove the hair pin and
push the lever upward to tilt the pans as shown. This allows any grain on the pans to dump into the
unload auger.
Figure 11A
12. Inspect the entire dryer for loose, worn or damaged parts. Include check of auger flighting, metering
rolls and other internal parts. Check that temperature sensors within the air plenum chamber are
secured within insulated clamps and do not chafe on other metal parts.
13. Make sure all dryer guards and warning decals are securely installed. Ensure that guards do
not interfere with moving parts. If guards or warning decals are missing, contact the dealer for a free
replacement.
14. Test fire the dryer several weeks ahead of the drying season. Check for possible gas leaks.
(See Page 48.)
NOTE: If on site bearing lubrication is to be performed, see lubrication instructions for ball bearing
motors. To keep motor bearings properly lubricated and dispel any accumulation of moisture
within the windings, the fan and auger motors should be operated for 15 to 30 minutes
each month.
PNEG-1702 ETL Listed GSI/FFI Portable Dryer Manual 83

Lubrication Procedure
If the motors are equipped with an alemite fitting, clean the tip of the fitting and grease with a grease gun.
Use 1 or 2 full strokes on motors in NEMA 215 frame and smaller. Use 2 to 3 st rokes on NEMA 254 through
NEMA 365 frame. Use 3 to 4 strokes on NEMA 404 frames and larger. On motors having drain plugs,
remove drain plugs and operate motor for 20 minutes before replacing drain plug. On motors equipped
with slotted head grease screw, remove screw and apply grease tube to hole. Insert 5 cm to 8 cm length
of grease string into each hole on motors in NEMA frame and smaller. Insert 8 cm to 13 cm length on larger
motors. On motors having grease drain plugs, remove plug and operate motor for 20 minutes before
replacing drain plug.
NOTE: All of the auger and metering roll bearings are lifetime lubricated and do not require
service lubrication.

CAUTION
Although the taper-lock method of retaining the blade onto the motor shaft is simple,
it is essential that the following points be read carefully and fully understood.
Improper installation can cause a loose flying blade and result in serious injury
or death.
Fan Blade Removal and Installation
When working on or around the fan blade, be aware that it may free wheel and could cause serious injury.
It may be helpful to gently wedge the propeller to prevent this from occurring. However, remember to
remove the wedge before restarting the fan.
If at any stage the blade has become damaged, it is important that it is repaired and that the
blade is balanced. Failure to do this could result in the blade running out of balance and potentially
exploding. Balancing the blade is a specialists job, if in doubt contact GSI or the dealer.
The fan blade is secured to the motor shaft by the use of a taper-lock bushing, motor shaft key and
three (3) cap screws.
When reassembling parts, the cap screws must be installed through the untapped clearance holes as
shown. This will cause the blade to be pulled forward onto the tapered bushing, thus locking the parts
securely onto the motor shaft. When fan servicing requires removal and installation of the blade, make
sure the blade is removed and reinstalled properly.
1. Lock out the fan power supply and remove the fan guard and the venturi, as required on
some models.
2. Remove the three (3) cap screws from the clearance holes in the taper-lock bushing.
3. Install two (2) of the cap screws into the threaded holes in bushing and turn them by hand until they
bottom against the front surface of the blade.
NOTE: The threaded holes within the bushing are provided for disassembly purposes only. Do not
attempt to use these holes for reassembly. They will not allow the parts to lock onto the shaft
thereby causing a hazardous operating condition.
4. Block blade to prevent it from turning and gradually turn the cap screws (up to 1/4 turn at a time) until
the blade breaks loose from the bushing and motor shaft. Carefully remove bushing a nd blade. With
the blade free from the bushing, a wheel can be used to pull the bushing off of the motor shaft.
Reattach bushing onto blade to prevent the loss of parts.
NOTE: During manufacturing, the blade and bushing are balanced together and are marked with
two (2) small dots to identify their original alignment position. Check the bushing and propeller
to make sure they have alignment marks. Mark the alignment of the propeller and bushing,
if necessary.
PNEG-1702 ETL Listed GSI/FFI Portable Dryer Manual 85
11. Service
Fan Motor Removal and Installation
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 motor warranty. Motor service and
repair at other places will be at owner’s expense.
If the service station determines motor failure is caused by faulty material or workmanship within the
warranty period, repair will be covered under the warranty. Motor failure caused by external sources will
result in a charge to the owner for repair.
1. Make certain power is shut off and locked out. Remove fan guard and blade.
2. Remove cover from fan/heater control box and disconnect the motor lead wires from within the box.
NOTE: Tag or otherwise identify wires for ease of reassembly.
3. Remove motor mount bolts. If there are shims between the motor and its base, note their location so
they can be properly installed during reassembly.
4. Disconnect the upper end of the motor conduit, then carefully pull the wires through the hole in the
fan/heater housing. Remove motor from the fan/heater unit with the conduit still attached. If motor
requires service, take it to an authorized service station.
5. To reinstall motor, slide onto motor base plate and replace shims (if required) between motor
base and plate. Reinstall motor mount bolts and washers, but do not fully tighten at this time.
6. Reinstall conduit and wires through hole in fan/heater housing and carefully connect all
electrical wiring.
7. Adjust position of motor by temporarily mounting the fan blade on the motor shaft. Rotate the fan
blade by hand, making the necessary adjustments, so the tip clearance between blade and housing
is uniform. If required, remove the fan blade and fully tighten all four (4) motor mount bolts.
NOTE: Make sure to install and tighten the blade in accordance with previous instructions.
Heater Parts Removal and Installation
Most of the heater parts can be removed by simply identifying any attached wiring and then disconnecting
the obvious mounting parts.
1. Flame Sensor: Disconnect the wire connector and unscrew the flame sensor out of its
mounting bracket.
2. Gas Solenoid Valve Coil(s): Unsnap either the plastic cap, or the metal clip on the gas valve and
slide the housing and coil off the valve stem and body. Do not energize the coil when it is removed,
as the coil may become damaged due to excessive current flow.
3. Regulator and Gas Solenoid Valve(s): The gas regulator and solenoid valve(s) are directional and
must be connected as indicated by the markings near the port openings. Make sure gas is shut off
and purged from the system before removing parts.
NOTE: When installing a liquid gas solenoid valve on LP models, do not over tighten the connection
into the inlet side, as the inlet orifice may become partially blocked.
86 PNEG-1702 ETL Listed GSI/FFI Portable Dryer Manual
11. Service
4. Main Gas Orifice: With fuel shut off and gas purged from system, proceed as follows:
a. Disconnect the plumbing support brackets from the pipe train.
b. Disconnect gas solenoid valve coils. Be sure to mark their original locations.
c. Lift pipe (with orifice, solenoid valve and other parts attached), straight up and remove from
fan/heater housing. Orifice and other parts can now be removed from pipe train, if desired.
5. Reassemble: To reassemble parts, reverse the disassembly procedure and check the following:
a. Make sure all parts are thoroughly cleaned and open.
b. Use a dependable brand of high temperature pipe caulking compound when assembling gas
connections. Apply only a light coating onto male threaded end of fittings.
c. Solenoid valves and gas regulations are directional and must be properly installed. Do not attempt
to connect gas solenoid valves by applying force to the valve core stem as it may ruin the unit.
d. Make sure all electrical wires are properly connected. Refer to wiring diagrams on Pages 89-107.
Metering Roll Servicing
This dryer is equipped with an SCR metering roll drive assembly. The metering rolls are driven by a
separate DC type electric motor. The speed of the motor is variable and is controlled by an electric
SCR control within the main control box.
Main Controls
1. SCR Speed Control 4" (GSI): The metering roll speed pots on the front of the con trol bo x regu late
the speed of the DC motor which drives the metering rolls. The scale of a djustment is from 0 to 999
which represents the flow of grain past the metering rolls as a percent of the maximum grain
discharge rate for the dryer.
NOTE: When the control is set to the maximum discharge rate (999), the metering roll speed should
be 17.5 RPM for 8" discharge auger.
SCR Speed Control 7" (FFI): The metering roll speed pots on the front of the control box regulate
the speed of the DC motor which drives the metering rolls. The scale of a djustment is from 0 to 999
which represents the flow of grain past the metering rolls as a percent of the maximum grain
discharge rate for the dryer
NOTE: When the control is set to the maximum discharge rate (999), the metering roll speed should
be 4.3 RPM for 8" discharge auger.
2. DC Electric Motor: The direct current (DC) motor provides the drive for the metering roll and is
located on the front left hand side of standard model dryers. The output shaft of the motor is
connected directly to the gearbox assembly. The DC motor requires no operational ad justment as it
is completely controlled from the control box.
3. Speed Reducer Gearbox: The direct drive gearbox provides the required speed reduction and
transmits power to the metering rolls through a drive chain arrangement. The gearbox does
not require adjustment. The drive chain should also be periodically lubricated and tightened
as necessary.
PNEG-1702 ETL Listed GSI/FFI Portable Dryer Manual 87
11. Service
CAUTION
Keep hands away from sprocket teeth to avoid injury from chain backlash, as a
result of torsion build up in the system caused by the jam.
4. Unload Auger Time Delay: The delay controls the bottom auger system and causes the unload
auger (and any connected auxiliary unloading conveyors) to continue operating for a programmed
amount of time, even after the metering rolls stop. This feature permits the clean out of grain within
the unloading equipment at the end of all discharge cycles.
5. If a foreign object becomes lodged in the metering rolls and jams the system, the unloading auger
will stay in motion. However, the metering roll drive will stop and the DC motor should stall out.
The vision control system will shutdown the dryer after a 2 minutes period.
To determine if the metering problem is from blockage, perform the following test with the power OFF.
Remove the drive chain by loosening the motor mounting bolts. Place a pipe wrench on the hub of the
roller chain sprocket on the left hand metering roll at the drive end of the dryer. Apply up t o 100 ft. lbs. of
force and attempt to rotate the roll toward the inside of the dryer. If the metering roll will turn, then repeat
for the right hand side. If the metering roll will turn, it can be assumed that no blockage exists and the
problem is from some other cause. Check for a break in the power train, chain, drive key, pin, etc.
How to Clear a Jammed Meter Roll (All Power “OFF”)
Place a pipe wrench on the hub of the sprocket of the jammed metering roll and turn the roll. First,
backward and then, forward several times in an attempt to dislodge the object and clear it thr ough the roll.
If this is not successful, have an assistant turn the metering roll and attempt to locate the jam by sound.
Shutdown the fan/heater and eliminate any other noise when making this check. Once the location is
determined, the roll can be reached from inside the plenum by opening the access door for the column
that has the jam and loosening the two (2) nuts holding the metering roll slide gat e high e nough to reach
in and remove the object causing the jam.
