INTRODUCTION
OPERATING PRECAUTIONS
READ THESE INSTRUCTIONS BEFORE
INSTALLATION and OPERATION.
SAVE FOR FUTURE REFERENCE.
Thank you for choosing a GSI Vision Series grain dryer. These units are among the finest grain dryers ever built;
designed to give you 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, single phase 230 volt, three phase 230 or 460 volt (60Hz) electrical
power.
USE CAUTION IN THE OPERATION OF THIS
EQUIPMENT
The design and manufacture of this dryer is directed toward operator safety. However, the very nature of a grain dryer
having a gas burner, high voltage electrical equipment and high speed rotating parts does present a hazard to personnel which
cannot be completely safeguarded against without interfering with efficient operation and reasonable access to components.
Use extreme caution in working around high speed fans, gas-fired heaters, augers and auxiliary conveyors which may
start without warning when the dryer is operating on automatic control.
Continued safe dependable operation of automatic equipment depends, to a great degree, upon the owner. For a safe
and dependable drying system, follow the recommendations within the manual and make it a practice to regularly inspect the
operation of the unit for any developing problems or unsafe conditions.
Take special note of the Operating Precautions listed below before attempting to operate the dryer.
Keep the dryer clean. Do not allow fine material to accumulate in the plenum chamber.
A CAREFUL OPERATOR IS THE BEST INSURANCE AGAINST AN ACCIDENT.
OPERATING PRECAUTIONS
1. Read and understand the operation manual before attempting to operate the unit.
2. Keep ALL guards, safety decals, and safety devices in place. Never operate dryer while guards are removed.
3. Keep visitors, children and untrained personnel away from dryer at all times.
4. Never attempt to operate the dryer by jumping or otherwise bypassing any safety devices on the unit.
5. Always set the main power supply disconnect switch to OFF and lock it in the OFF position using a padlock before
performing any service or maintenance work on the dryer or the auxiliary conveyor equipment.
6. Before attempting to remove and reinstall the fan blade, make certain to read recommended procedure listed within the
SERVICING section of the manual.
7. Keep the dryer and wet holding equipment CLEAN. Do not allow fine material to accumulate.
8. Set pressure regulator to avoid excessive gas pressure applied to a burner during ignition and when burner is in operation.
See page 19 for operating gas pressures. Do not exceed maximum recommended drying temperatures.
9. Do not operate the dryer if any gas leak is detected. Shut down and repair before further operation.
10. Clean grain is safer and easier to dry. Fine material can be highly combustible, and it also requires removal of extra
moisture.
11. Use CAUTION in working around high-speed fans, gas burners, augers, and auxiliary conveyors which can start
automatically.
12. Be certain that capacities of auxiliary conveyors are matched to dryer auger capacities.
13. Do not operate in an area where combustible material will be drawn into the fan.
14. The operating and safety recommendations in this manual pertain to the common cereal grains as indicated. When drying
any other grain or products, consult the factory for additional recommendations.
15. Routinely check for any developing gas plumbing leaks. Check LP vaporizer for contact with burner vanes.

SETTING THE TIMERS
Setting the timers for the dryer is a simple procedure. To set the timers touch the buttonat the bottom of
Operation Screen. A new screen will appear called the Select Timers to Modify screen (shown on the left). As you can see there
are 4 timers that you can modify:
1.) Load Delay: (Default setting - 2
minutes)This delay is used to delay the
starting of the load auger when the
dryer is unloading to prevent the load
auger from cycling to often. The load
delay is active only when the load auger
switch in the auto position.
2.) Out of Grain (OOG) Timer:
(Default setting - 8 minutes)The OOG
timer should be set to the maximum
time it takes for your dryer to refill
during continuous or batch drying
modes. Note that the computer will
display the time required to fill your
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: (Default setting - 3 seconds) The Fan Sequence Delay timer controls the amount of time between each fan startup to reduce the dryer start-up amperage.
4.) Unload Delay: (Default setting - 1 minute)The Unload Delay
timer is used to control the amount of time the unload auger runs
after the metering rolls stop to allow the unload auger to clean itself
out.
To setup a timer touch the button of the timer you wish to modify.
The Modify Timer Setpoint screen will then be displayed (see
image at left). Note that there are two number pads on this modify
screen. The left number pad is used to modify the minutes and the
right number pad will modify the seconds. Touching the Default
button will automatically set the timer to the default setpoint for
that timer. The Accept button will save the timer setpoint displayed
in the time display. Touching Cancel will exit the Modify Timer
Setpoint screen without saving any changes and the timer will stay
at the currently saved setpoint.
Once you have the timer setpoints set touching the Exit button at the bottom of the Modify Timer Setpoint screen will return you
to the Operation Screen.
SETTING THE TEMPERATURES
Setting the temperature setpoints for the dryer is a simple procedure. To adjust the temperture setpoints touch the
button at the bottom of Operation Screen. A new screen will appear called the Select Temperature Setpoint to Modify screen
(shown at the top of the next page). As you can see you modify the setpoint for each of the plenums by touching the desired
plenum button.
NOTE: Plenum one is the bottom plenum and plenum two is the top plenum for a two fan dryer. Use plenum one for a single
fan dryer.

TEST FIRING
DRYER PRESEASON CHECKS
This section gives a series of checks to be carried out on the dryer before starting for the first time in the drying
season. If any of the checks fail to produce the stated result, you should consult your dealer.
YOU SHOULD NOT ATTEMPT TO USE THE DRYER UNLESS ALL THE PRE-START CHECKS HAVE
BEEN SUCCESSFULLY COMPLETED.
BEFORE ATTEMPTING TO
OPERATE THE DRYER MAKE SURE ALL SAFETY SHIELDS ARE IN PLACE, ALL BOT-
TOM CLEAN OUT AND REAR ACCESS DOORS ARE CLOSED AND ALL PERSONNEL ARE
CLEAR OF THE DRYER
INSPECT THE METERING ROLLS
Open all metering roll access doors and inspect each compartment for any bolts, nuts or other foreign material, that may
cause possible jamming of the metering rolls.
CHECK CONTROL PANEL SWITCHES
Before applying electrical power to the dryer, be sure that all switches on the dryer control panel are in the OFF position.
ELECTRICAL POWER
Turn on the electrical power supply to the dryer, set all circuit breakers to on, including the safety disconnect handle mounted
on front of the dryer power panel.
CONTROL POWER SWITCH
Turn the control power switch to on. At this point the controller will lock out all other dryer functions. Once the Boot
Screen appears (see page 12), touch the START DRYER button and the dryer will perform a safety circuit check. If a fault is
found, the cause will be displayed on the Main Screen. If all are found safe, the controller will supply power to the electronic
fuel shut-off valve (Maxon), if so equipped, and the start switch will light up, indicating that the dryer is ready to be started.
START SWITCH
Push the dryer start switch, and all the selector switches on the control panel will be activated.
FUEL CHECK
If using LP gas, make sure the tank has plenty of fuel and that the tank does not have a regulator mounted on the liquid line.
Slowly open the main fuel supply valve at the tank. Then, open the electronic shut off valve (Maxon valve), if so equipped, or
open the manual shut off valve on the dryer to allow fuel flow to the dryer.
If using natural gas, make sure an adequate supply is available. Turn on the valve along the supply line. Then, open the electronic shut off valve (Maxon valve). Inspect all gas lines and connections for possible leaks.
Any gas leaks must be fixed immediately!
LOAD AUGER
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 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 eight (8) min-
