Safety Precautions
READ THESE INSTRUCTIONS BEFORE INSTALLATION AND OPERATION
SAVE FOR FUTURE REFERENCE
1. Read and understand the operating manual before attempting to operate the dryer.
2. NEVER operate the dryer while the guards are removed.
3. Power supply should be OFF for service of electrical components. Use CAUTION in checking voltage
or other procedures requiring the power to be ON.
4. Check for gas leaks at all gas pipe connections. If any leaks are detected, DO NOT operate dryer.
Shutdown and repair before further operation.
5. NEVER attempt to operate the dryer by jumping or otherwise bypassing any safety devices on
the unit.
6. Set pressure regulator to avoid excessive gas pressure being applied to the burner during ignition
and when the burner is in operation. DO NOT exceed maximum recommended drying temperature.
7. Keep the dryer clean. DO NOT allow fine material to accumulate in the plenum chamber.
Clean grain is easier to dry. Fine material increases resistance to airflow and requires removal
of extra moisture.
8. Keep auger drive belts tight enough to prevent slippage.
9. Use CAUTION in working around high speed fans, gas burners, augers and auxiliary conveyors
which can START AUTOMATICALLY.
10. Keep area around air inlet to the fan clear of any obstacles and combustible materials.
11. BEFORE attempting to remove and reinstall any propeller, make sure to read the
recommended procedure.
12. Make sure 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.
PNEG-1935 Vision Hybrid for Portable Dryers 7
1. Safety
Use Caution in the Operation of this Equipment
This dryer is designed and manufactured with operator safety in mind. However, the very nature of a grain
dryer having a gas burner, high voltage electrical equipment and high speed rotating parts, presents
hazards to personnel which cannot be completely safeguarded against withou t interfering with the efficient
operation of the dryer and reasonable access to its 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 Owner’s Manual and make
it a practice to regularly inspect the unit for any developing problems or unsafe conditions.
Take special note of the Safety Precautions on Page 7 before attempting to operate the dryer.

5. Operations
Timers Button
Select the button. A new screen will appear called the “Select Timer to Modify” screen.
(See Figure 5B.) There are five (5) timers that can be modified.
Figure 5B
1. Load Delay: (Default setting - 2 minutes) This delay is used to prevent the load auger from
over-cycling. The load delay is active only when the Load switch is in the AUTO position. The timer
starts when the dryer calls for grain.
2. Out Of Grain (OOG) Timer: (Default setting - 8 minutes) The “OOG” timer should be set to the
maximum time it takes for the dryer to refill during continuous or batch drying modes. The computer
will display the time required to fill the dryer on the previous load, aiding you in setting an accurate
time. If the dryer runs out of grain while the Load 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 Delay” timer controls the amount of time between
each fan startup to reduce the dryer inrush amperage.
4. Unload Delay: (Default setting - 1 minute) The “Unload Delay” timer is used to regulate the amount
of time the unload auger runs after the metering rolls stop.
5. Cool Down: (Default setting - zero seconds) The dryer fans will operate for a “Cool Down” period in
the event that the dryer experiences a shutdown, other than that of a plenum, grain high temperature
or fan motor overload situation. The dryer can also be restarted by pressing the “Start” button on
the front of the Vision control panel. This prevents the fans from shutting down because of
nuisance warnings.
To change a timer setpoint, touch the button of the timer you wish to modify. The “Modifying Timer
Setpoint” screen will then be displayed, which is shown in Figure 5C on Page 23. T he left nu mber pad is

3. Unload Parameters:
a. Set Maximum Unload Rate: The meter roll speed set point cannot be set higher than this value.
This prevents choking downstream augers.
b. Set Minimum Unload Rate: The meter roll speed setpoint cannot be set lower than this value.
(See Figure 5J.)

5. Operations
4. Plenum Temp Manager: This will reduce the plenum temperature setpoint(s) if the
unload rate reaches its maximum allowable value for the time specified by the “Time Between Steps”
menu. Once the time has been exceeded, the dryer will reduce the temperature setpoint(s) by the
value given in the “Size of Temperature Step”. If the unload rate falls below the maximum allowable
value for the “Time Between Steps” period, the temperature setpoint(s) will be increased by the “Size
of Temperature Steps” until the original setpoints are met. (See Figure 5K.)
NOTE: Default setting is “OFF”.

Burner Mode:
The button will display the “Select Burner Mode” screen.
NOTE: The bottom heater is always Heater one.

5. Operations
The “Select Burner Mode” screen will allow the operator to select the type of burner operation for
each burner. The user has three (3) options: HI/LO, ON/OFF and AUTO modes.
a. HI/LO Mode (Default Setting): The burner will switch from high heat to low heat when the
plenum temperature setpoint has been reached.
b. ON/OFF Mode: The burner will shut OFF when the upper temperature setpoint has been
reached and turn back on when the lower temperature setpoint has been met.
NOTE: Useful for low plenum temperature settings in warm conditions.
c. AUTO Mode: All burners in HI/LO will be started. If the burner stays in “Low-Fire” for 60 seconds
or the plenum temperature exceeds the setpoint plus 20° for 10 seconds, that burner will switch
to ON/OFF operation.
NOTE: Useful in very warm ambient temperature conditions.
To select modes, touch the “Select” button for the fan/heater you wish to change. Touching the
“ALL HI/LO” button will set all burners to HI/LO and the same procedure can be duplicated for the
“ALL ON/OFF” and “ALL AUTO” buttons. Choose the “ACCEPT” button to save any changes and
return to the “Setup Screen” or choose “CANCEL” to return to the “Setup Screen” without saving
any changes.

Calibrate Moisture Sensor:
dryer - one for incoming grain (wet) and another for outgoing (dry). Each device has one moisture
and one temperature sensor included. (See Figure 5M.)
There are two (2) moisture/temperature sensors per
Figure 5M
Calibrating moisture: Take several moisture samples of the grain over an extended period of
time, average these values and calibrate the sensors accordingly.
Example: If the dryer’s exiting moisture (dry) is reported at 15.5% on the Vision screen and the
averaged samples yielded a value of 15%, then the calibration screen would be used to enter
-0.5% as the “Dry Moist Offset”.
Calibrating temperature: Take several temperature samples of the grain over an extended
period of time, average these values and calibrate the sensor accordingly.
Example: If the dryer’s incoming temperature (wet) is reported to be 105°F on the Vision scree n
and the average samples yield a value of 100°F, adjust the “Dry Temp” to -5.
