4. Dryer Installation
Dryer Layout
System Layout
Consider the grain handling system and location of storage bins and existing conveyors when selecting
dryer site, to facilitate wet grain supply and dry grain discharge to conveyors. Other considerations are
prevailing wind direction, fuel and power supply locations, noise and convenience of control location.
Site Location
The dryer should not be operated inside a building or in any area not permitted by electrical code,
fuel installation regulations or insurance requirements. Do not operate in an area where combustible
material can be drawn into the dryer. Maintain a minimum distance of five feet (5') to other structures.
Refer to dryer specifications on Page 11 and dimensions on Pages 12, 13 and 14.
Foundation
The dryer should be placed on a reinforced concrete slab located in a well drained area. See Figure 4A
on Page 16, Figure 4B on Page 17 and Figure 4C on Page 18 for re commended dryer foundations for soils
with minimum soil bearing pressure of 3000 lbs/ft².
Liquid Propane (LP) Dryers with Internal Vaporizers
Liquid Draw
The dryer is designed to operate on liquid propane, with liquid draw from the supply tank. A piping
system is provided on the dryer, including strainer, pressure relief valve and manual shut off valve.
(See Figure 4D on Page 19.)
Ammonia Tanks
Do not use propane supply tanks which have previously contained ammonia or fertilizer solutions.
These substances are extremely corrosive and damaging to fuel supply and burner parts.
Oil or Water in Tanks
With liquid draw from the supply tank, any water present in the tank may freeze in the piping and con trols
in cold weather. To ensure that tanks are free of moisture, the usual precautio n is to purge with methanol.
Avoid tanks which may contain an accumulation of oil or heavy hydrocarbons from long use on a vapor
withdrawal system.
Natural Gas (NG) Dryers
Gas Volume and Pressure
The dryer is designed to operate on natural gas having a heat value of about 1000 BTU per cubic foot.
The dryer is equipped with a natural gas supply pipe system connected to the heater solenoid valves.
A regulated pressure of 10 PSI must be provided at the connection to the dryer, with gas available in
sufficient volume to maintain operating pressure. (See Figure 4E on Page 19.)

Electrical 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 enough to prevent low voltage damage to motors and
control circuits.
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 on KVA rating of transformers, considering total horsepower 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 and a fter motor is running at
full speed it should be within 8% of normal voltage.
Power Supply Disconnect
All dryers are equipped with a power disconnect switch in the power box to permit total power shut down
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 shut down.
Machine to Earth Grounding
It is very important that a machine to earth ground rod be installed at the dryer. Place the ground rod that
comes standard, within eight feet (8') of the dryer and attach it to the dryer control panel with a t 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. The proper grounding will provide additional safety
in case of any short and will ensure long life of all circuit boards, SCR drive and the ignition system.
The ground rod must be in accordance with local requirements.
20 PNEG-1458 T-Series Tower Dryer
4. Dryer Installation
Proper Installation of Ground Rod
It is not recommended that the rod 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. The water will work its way down the hole, making it possible
to work the rod completely into the ground. This method of installation assures good contact with the
surrounding soil, making a proper ground.
5. Connect the bare, copper ground wire to the rod with 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. Insulated wire is not recommended for
grounding applications.
Connecting Auxiliary Conveyors
The auxiliary load and auxiliary unload augers or conveyors can be wired directly to the dryer. The
maximum horsepower of auxiliaries that can be wired to the dryer is 10 horsep ower. If an auxiliary motor
is larger than what is recommended, then it must be powered from a source outside the dryer and must
use a separate contractor and overload protection device for each motor. However, the operation of the
auxiliaries can be performed by the control panel.
It is recommended that you contact the local power company and have a representative survey the
installation to see that the wiring is compatible with their system and that adequate power is supplied
to the unit. Remember that the only thing connected to the recommended service amps should be the
grain dryer. Standard electrical safety practices and codes should be used. (Refer to National Electrical
Code Standard Handbook by National Fire Protection Association.) A qualified electrician should make all
electrical wiring installations.

Vision Control Panel Layout
Figure 5A
The vision control system is a state of the art dryer controller used on several GSI drying products. The
vision control can operate any dryer in either a batch or a continuous flow mode. Therefore, all operating
instructions for the T-Series dryer describes continuous flow operation only.
Control Power Switch
The vision control system is turned ON or OFF with this switch.
NOTE: This switch does NOT disconnect the power that is present at the breakers, contractors,
transformers, fuses or other electrical components found in the control or power box. Turn the main
disconnect handle located on the power box to the OFF position prior to servicing any of the
installed components.
Fan Switch
The fan is turned ON or OFF with this switch. Turning the switch to the ON position will turn the fan ON.
Turning the switch to the OFF position turns the fan OFF. The light inside the switch will illuminate
whenever the air pressure sensor senses air movement through the fan. (NOTE: The fan AUT O position
is not used.)
22 PNEG-1458 T-Series Tower Dryer
5. Operating Controls
Heater Switch
The burner is turned ON or OFF with this switch. Turning the switch to the ON position will start the
burner ignition sequence if the fan is also running. Turning the switch to the OFF position turns the
burner OFF. The light inside of the switch will illuminate only when the flame sensor detects the burner
flame. (NOTE: The heater AUTO position is not used.)
Load Auger Switch
This switch is used to select the operation of the wet fill conveyor. In both the AUTO and the MANUAL
positions, the wet fill conveyor will operate if the dryer is low on grain and will automatically shut off
when the dryer is full. In the AUTO position only, the dryer will automatically shut down should the dryer
go low on grain. The time period between the dryer going low on grain and the actual shut down is
determined by the setting on the out of grain timer. In the MANUAL position, the out of grain timer is
deactivated. The MANUAL switch position should be used for initially filling the dryer. The AUTO switch
position should be used during normal dryer operation. The switch will illuminate whenever the load auger
is operating.
Unload Switch
The Unload switch turns the accutrol metering system and the unload conveyor ON or OFF and also
selects the operation of the metering system. In the MANUAL position, the metering system operates
at the speed set by the Metering Roll Speed Rotary switch. In the AUTO position, the metering system
switches to a multi-speed operation controlled by the automatic moisture control. The switch will illuminate
whenever the unload auger is operating.
Outside Light Switch
The service light is turned ON or OFF with this switch. In the AUTO position, the light is turned ON
while the dryer is running automatically and turns OFF if a shut down occurs. In the ON position, the light
is turned ON.
Start Switch
This switch starts and operates the dryer. If all of the above Dryer Operational switches are in the OFF
position, each component can be turned ON by turning the component switch to the ON position after the
run switch has been pressed. Or, if the Operational switches are preset to their ON position, the vision
controls will sequentially start the various dryer components after the run switch is pressed.
Stop Switch
This switch stops all dryer functions except the blower. If the Blower switch is in the ON position, the blower
will continue to run for 15 minutes. If you desire the blower to be OFF, simply turn the Blower switch to the
OFF position. If an automatic dryer shut down occurs, first determine and correct the cause of the shut
down. Then press the Dryer Power Stop button to reset the dryer before restarting.

Setting the Timers
Setting the timers for the dryer is a simple procedure. To set the timers, touch the button at the
bottom of Operation screen. A new screen will appear called the Select Timers to Modify screen.
(See Figure 6C on Page 26.) As you can see there are five (5) timers that you can modify:
1. Load delay: This delay is used to delay the starting of the load conveyor when the dryer is unloading
to prevent the load conveyor from cycling to often.
2. Out of grain (OOG) timer: The OOG timer should be set to the maximum time it takes for the dryer
to refill. Note that the computer will display the time required to fill the dryer on the previous load
operation to aid you in setting an accurate time. If the dryer runs out of grain while the Load Auger
switch is in the AUTO position, the OOG timer automatically shuts off the dryer after the period of
time preset on the timer.
3. Fan delay timer: The fan sequence delay timer.
4. Cool down timer: The cool down timer is used to set the amount of time the fan is to run, after a
non-heat related shut down. Setting to 0 will cause an immediate shut down on a warning. The range
is from 0 to 20 minute.
5. Unload delay timer: The unload delay timer is used to control the amount o f time the unloa d auger
runs after the metering system stops to allow the unload auger to clean itself out.
