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.

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 used to modify the minutes and the right number pad will modify the seconds.

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.

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.

Moisture Control Options

Moisture Control is used to regulate the moisture of the outgoing grain. For example, if a user is drying corn, the desired moisture content of the dried corn is usually around fifteen p ercent (15%). The moisture control schemes are designed to achieve that value with minimal effort from the user.

These controls can be split into two (2) distinct modes of operation: Continuous Flow and Stage Batch. Continuous Flow runs the metering rolls continuously, whereas Stage Batch unloads a p ortion of the dryer at a time.

Continuous Flow Drying

There are two (2) parameters the dryer can monitor to adjust Continuous Flow operation in an attempt to have consistent outgoing moisture: Temperature and Moisture. When we say “Adjust Continuous Flow Operation”, this means changing the unload rate of the dryer. By varying the unload rate, this changes the amount of time the grain stays in the drying chamber. This results in heating the grain more or less, depending on whether the unload rate is increased or decreased.

The following is a depiction of how the Continuous Flow modes break down.

Temperature Controlled Schemes

The temperature controlled schemes use the grain temperature sensors as a reference parameter. As the grain temperature varies, the controls adjust the unload rate accordingly.

For example, we will assume a grain temperature setpoint of 105°. If the grain temperature sensor on the dryer is reporting 110°, the grain is 5° hotter than we would like it to be. To adjust the operation, the control scheme would realize the grain is getting too hot and increase the speed of the unload to lessen the amount of time the grain is exposed to the heating chamber. The opposite is true if the grain temperature sensor on the dryer reports lower than the setpoint. The unload rate would decrease. This means the grain temperature is directly proportional to the unload rate. If the grain temperature rises, the unload rate should increase.

The temperature controlled schemes have an exclusive option available for drying rice. This option is available in the two (2) temperature modes by switching the “COMP” dipswitch on the Display I/O board. The only change in the 2 Speed and 5 Speed temperature modes when drying rice is instead of monitoring the four (4) temperature sensors located at the 60% point of the column, it monitors the temperature

38 PNEG-1935 Vision Hybrid for Portable Dryers

sensor at the discharge. This allows the kernel temperature to stay at or below a set temperature with a kernel temp shutdown alarm during multiple pass drying common in rice. This is an exclusive GSI Group feature.

6. Moisture Control Options

2 Speed Temperature

When to Use:

For use when good management is available and a quick reacting time is desired in all heat or dry and cool operation.

How it Works:

The user specifies two (2) desired meter roll speeds (Low and High) and a grain temperature setpoint for this scheme. If the grain temperature sensors on the dryer report a temperature 1° above the setpoint, the dryer will select the fastest unload rate (High). If the sensor reads 1° below the setpoint, the controller will run at the slower speed (Low).

There is also an “ON/OFF” option associated with the 2 Speed. The user only specifies one unload rate (ON) and the controller knows the other speed is zero (OFF). If the temperature sensor reads 1° above the setpoint, the metering rolls will run at the “ON” speed. The metering rolls are turned OFF if the temperature falls below the setpoint.

NOTE: A “Max Grain Temp” is available for this scheme. By enabling this feature, the dryer will shu tdown

and issue a warning if the grain temperature exceeds the “Max Grain Temp” value.

Setup Procedure

1. Press the “Stop” button on the control panel if the dryer is running.

2. From the “Setup” screen, select “Drying Mode”, then “Continuous Flow”.

3. From the “Drying Mode Selection” screen, select “M/C Setup” to access “Continuous Flow Setup”.

4. Select “Temperature” from the “Continuous Flow Control Schemes” group.

5. If desired, enable the “Max Grain Temp” safety.

6. Select “2 Speed” from the “Temp Based Options” group.

7. Press the “Accept” button and return to the “Default Operation Screen”.

8. Press the “Meter Roll Speed” adjustment knob to access the “Modifying Meter Roll Speed Setpoints” screen.

9. If the “ON/OFF” option is desired, verify the “ON/OFF” check box at the top right of the window is selected. If “ON/OFF” is not desired, make sure the “2 Speed” check box is selected.

10. Press the “Meter Roll Speed” adjustment knob until the “HIGH SP” bar is colored red. Adjust the “HIGH SP” by turning the knob until the desired setpoint is reached.

11. If “ON/OFF” is selected, skip to the next step. Depress the knob until the “LOW SP” bar is colored red. Turn the knob until the setpoint is attained.

12. Press “Accept/Exit”.

13. From the “Default Operation Screen”, press the “M/C” button and enter a grain temperature setpoint.

14. Turn the “Unload” switch to the “AUTO” position.

15. Press the “Start” button on the control panel.

6. Moisture Control Options

5 Speed Temperature

When to Use:

For use with a wider moisture variation spread and for when a close and quick reacting moisture control is desired in all heat or dry and cool operation.

How it Works:

There are five Speeds associated with this drying scheme, but the user only selects one unload rate. The meter roll setpoint is used as the middle or medium speed. The other four Speeds are offsets of the medium speed, two higher and two lower. These offsets are labeled as follows: Low (LO), Medium-Low (M-LO), Medium (MED), Medium-High (M-HI) and High (HI). The unload rate is determined by the difference between the grain temperature setpoint and the actual temperature sensor reading. If the reading is exactly that of our temperature setpoint (a zero offset), MED would be selected, because we must be at the correct speed.

When setting up the 5 Speed Temperature scheme, there are two (2) sets of parameters: “Inner” and “Outer”. Both have a temperature and a meter roll speed associated with the m. “Inner” refers to the M-LO and M-HI speeds, while “Outer” refers to LO and HI.

Let’s pretend we have the parameters set as they are presented in the following table.

Inner (M-LO and M-HI) Outer (LO and HI)

Temperature 1° 3°

Meter Speed Offset 3% 12%

We will set the meter roll setpoint to 50% and grain temperature setpoint to 100° for convenience. If the grain temperature actually is 100°, the MED unload would be selected (50% in our example). Should the grain temperature climb to 101°, the controller will change to M-HI, which increases the unload rate by 3%. Now the dryer’s unload is running at 53% (50% + 3% = 53 %). If the grain temperature contin ues to climb, reaching 103°, HI will be selected which increases the unload rate by 12%. This 12% increase is in relation to the MED speed, NOT the M-HI, so the unload rate is now at 62% (50% + 12% = 62%). If the grain temperature falls back below 105°, the controller changes back to M-HI.

The same is true for grain temperatures below the setpoint, only the values are subtracted rather than added. If the grain temperature falls to 99°, the controller will select M-LO, changing the unload rate to 47% (50% - 3% = 47%).

The following table depicts how the controller would act when setup as the example above.

6. Moisture Control Options

This scheme also has a feature called “Auto-Centering”. If the controller is staying in HI the majority of the time, it probably means the metering roll setpoint (MED) is set too low. To alleviate this problem, the unload rate is continually averaged. Once an hour, the controller changes the metering roll setpoint (MED) to the averaged value. So in the example above, if the controller stayed in HI for an entire hour, it would change the metering roll setpoint to 62% and would now act according to the table below.

PNEG-1935 Vision Hybrid for Portable Dryers 41

6. Moisture Control Options

Moisture Controlled Schemes

The moisture controlled schemes use the exiting moisture sensor as a reference parameter. As the grain moisture content varies, the controls adjust the unload rate accordingly.

For example, our outgoing (dry) moisture setpoint will be set at 15%. If the outgoing moisture sensor reports a reading of 16%, the grain is 1% wetter than we desire. To account for this, we decrease the unload rate, therefore increasing the amount of time the grain is in the heating chamb er. The relationship between moisture and unload rate is inversely proportional. As the exiting moisture increa ses, the unload rate should decrease.

5 Speed Moisture

When to Use:

For use with a wider moisture variation spread and for when a moderate reacting moisture control is desired in all heat operation. Not recommended for dry and cool operation.

How it Works:

There are five Speeds associated with this drying scheme, but the user only selects one unload rate. The meter roll setpoint is used as the middle or medium speed. The other four Speeds are offsets of the medium speed, two higher and two lower. These offsets are labeled as follows: Low (LO) , Medium-Low (M-LO), Medium (MED), Medium-High (M-HI) and High (HI). The unload rate is determined by the difference between the moisture setpoint and the actual moisture sensor reading. If the re ading is exactly that of our moisture setpoint (a zero offset), MED would be selected, because we must be at the correct speed.

When setting up the 5 Speed Moisture scheme, there are two (2) sets of parameters: “Inner” and “Outer”. Both have a moisture and meter roll speed associated with them. “Inner” refers to the M-LO and M-HI speeds, while “Outer” refers to LO and HI.

Let’s pretend we have the parameters set as they are presented in the following table.

Inner (M-LO and M-HI) Outer (LO and HI)

Moisture 0.2% 0.5%

Meter Speed Offset 3% 12%

We will set the meter roll setpoint to 50% and the dry grain moisture setpoint to 15% for convenience. If the dry grain moisture is actually 15%, the MED unload would be selected (50% in our example). Should the dry grain moisture climb to 15.2%, the controller would change to

M-HI

, which increases the unload rate by 3%. Now the dryer’s unload is running at 53% (50% + 3% = 53%). If the dry grain moisture continues to climb, reaching 15.5%, HI will be selected which increases the unload rate by 12%. This 12% increase is in relation to the MED speed, NOT the

M-HI

, so the unload rate is now at 62% (50% + 12% = 62%). If the

dry grain moisture falls back below 15.5%, the controller changes back to LO-HI. The same is true for dry grain moistures below the setpoint, only the values are subtracted rather than

added. If the dry grain moisture falls to 14.8%, the controller will select M-LO, changing t he unload rate to 47% (50% - 3% = 47%).

6. Moisture Control Options

Variable Moisture

When to Use:

For use when minimum moisture management is available and when large, quick changes in moisture are not expected. Can be used during all heat and dry and cool operation.

How it Works:

The user should stabilize the dryer with the Unload switch in the “MANUAL” position. It is imperative that the dryer is outputting the desired moisture content grain before switching the unload to the “AUTO” position. Within one minute of switching the unload to “AUTO”, the dryer uses the current state of the sensors as a reference for future adjustments. The dryer will then run through a 30 minutes learning period and controller adjustments will begin after.

The controller continuously monitors the moisture coming in and out of the dryer and the column grain temperature 2/3 of the way down the dryer. The control actio n is mainly based on the dry moisture se nsor at the outlet of the dryer. If the moisture coming out of the dryer is not rig ht at the target, the controlle r will speed up or slow down the unload rate accordingly. The wet moisture sensor and the grain temperature sensor are intended to detect moisture spikes coming into the dryer so that the moisture controller can react ahead of time. For example, if the wet sensor detects a jump of moisture coming into the dryer, the controller will start slowing down the unload speed immediately. However, the controller does not act to the full scale right away. Instead, it slows down the dryer gradually so that the grain currently in the dryer will not be over-dried.

NOTE: The wet moisture sensor can be disabled in this scheme. The wet moisture reading reported will

be ignored by the calculations.

NOTE: A “Max Grain Temp” safety is available for this scheme. By enabling this feature, the dryer will

shutdown and issue a warning if the grain temperature exceeds the “Max Grain Temp” value.

Staged Batch Drying

Stage batch drying is comprised of three (3) phases: Drying, Cooling and Unloading.

1. Drying Phase - All fans and burners are on during this phase. Unload is OFF.

2. Cooling Phase - All fans are on during this phase. Any burner in the “AUTO” position is turned OFF during this phase. If the burner is in the “ON” position, it will remain on for this period. The unload is OFF.

3. Unloading Phase - All fans and burners in the “AUTO” position are turned OFF during this phase. Any fan or burner in the “ON” position will remain on for this period. The unload is ON.

A batch is defined as some portion of the drying basket’s capacity. A full batch refers to 100% of the basket’s capacity, one-half batch refers to 50%, etc. The different batch sizes are determined by the unloading phase of the cycle. If it takes 20 minutes for the dryer to fully unload and the “Unload” timer is set to 10 minutes, this would be considered a 1/2-1/2 batch (50/50).

The drying phase is considered the variable phase of the three. The cooling and unloading are timers set by the user and usually do not change. The moisture control portion only manipulates the length of the drying phase. There are three (3) control parameters that are used to establish the length of the drying period: Time, Temperature and Moisture.

If the dryer is an 1100 series, while in one of the Time or Temperature schemes, the user can choose between single or dual plenums. With “Single Plenum” selected, the plenum setpoint remains the same for the entire drying phase. If “Dual Plenum” is chosen, the plenum setpoint will be at one value for an amount of time and change to another setpoint for the remainder of the drying phase. When the switch between plenum setpoints occurs depends on which control parameter is being used (Time or Temperature).

Time Controlled Scheme

When to Use:

This scheme is used when the user would like to expose the grain to heat for no longer than a given amount of time.

PNEG-1935 Vision Hybrid for Portable Dryers 45

6. Moisture Control Options

How it Works:

Single Plenum: The user enters two (2) parameters: Dry Timer and Plenum Setpoint(s). The drying phase consists of heating the plenum to the setpoints for the dry timer period. Once the dry timer expires, the controller moves on to cooling.

Dual Plenum: The user enters four (4) parameters: Hi-Heat timer, Lo-Heat timer, Plenum Hi-Temp and Plenum Lo-Temp. The drying phase begins by using the Plenum Hi-Temp setpoint until the Hi-Heat timer has expired. The controller then changes to the Plenum Lo-Temp for the Lo-Heat timer period. Once the Lo-Heat timer expires, the controller moves on to cooling.

Single and Dual Plenum: A “Max Grain Temp” safety is available for this scheme. By enabling this feature, the dryer will shutdown and issue a warning if the grain temperature exceeds the “Max Grain Temp” value.

Setup Procedure

1. Press the “Stop” button on the control panel if the dryer is running.

2. From the “Setup” screen, select “Drying Mode”, then “Staged Batch”.

3. From the “Drying Mode Selection” screen, select “M/C Setup” to access “Staged Batch Setup”.

4. Select “Time” from the “Staged Batch Drying Criteria”. Make sure only the “Time” check box is selected, as it is possible to have “Time” and “Temperature” selected at the same time. If “Temperature” is selected, press the “Temperature” button to de-select it.

5. If desired, enable the “Max Grain Temp” safety.

6. Select “Single” or “Dual” plenum.

7. Return to the “Default Operation Screen”.

8. Set the Dry Timer(s), Cool Timer and Unload Timer to the desired time.

9. Press the “Temp” button and set the plenum(s) to the preferred temperature(s).

10. Position “Unload” switch in the “AUTO” position.

11. Press the “Start” button on the control panel.

Temperature Controlled Scheme

When to Use:

This scheme is used when the user would like to heat the grain to a specific temperature.

How it Works:

Single Plenum: The user enters two (2) parameters: Grain Temperature Setpoint and Plenum Setpoint(s). Until the Grain Temperature sensor reading is above the Grain Temperature setpoint, the plenum(s) will be heated to their respective temperatures. Once the Grain Temperature setpoin t has been met, the controller will move on to cooling.

Dual Plenum: The user enters four (4) parameters: Hi-Temp, Lo-Temp, Plenum Hi-Temp and Plenum Lo-Temp. The drying phase begins by using the Plenum Hi-Temp setpoint until the grain temperature reaches the grain “Hi-Temp” setpoint. The controller then changes to the plenum “Lo-Temp”. Once the grain Lo-Temp setpoint is met, the controller moves on to cooling.

Single and Dual Plenum: A “Max Time” safety is available for this scheme. By enabling this feature, the dryer will shutdown and issue a warning if the drying phase lasts longer than the “Max Time” specified.

13. Press the “Start” button on the control panel.

Time and Temperature Controlled Scheme

When to Use:

This scheme is used when the grain must heat for a minimum amount of time and must reach a desired grain temperature.

How it Works:

Single Plenum: The user enters three (3) parameters: Dry Timer, Grain Temperature Setpoint and Plenum Setpoint(s). The controller will remain in the drying phase at least as long as the Dry Timer. Once the Dry Timer has expired, the controller will check the grain temperature sensor. It will remain in the drying phase until the grain temperature setpoint is reached.

Dual Plenum: The user enters six (6) parameters: Hi-Heat timer, Lo-Heat timer, Hi-Temp, Lo-Temp, Plenum Hi-Temp and Plenum Lo-Temp. The controller begins with the Plenum Hi-Temp as the plenum setpoint and will remain there until both the Hi-Heat timer and grain Hi-Temp conditions are met. Plenum Lo-Temp is then used for the remainder of the drying phase. The drying phase ends when the Lo-Heat timer expires and the grain temperature exceeds the grain Lo-Temp setpoint.

Single and Dual Plenum: Two (2) safeties are available for this scheme: “Max Time” and “Max Grain Temp”. By enabling this feature, the dryer will shutdown and issue a warning if the drying phase runs longer than the “Max Time” period, or if the grain temperature exceeds the “Max Grain Temp” value.

Moisture Controlled Scheme

When to Use:

This scheme is used when the user would like the controller to vary the length of the drying phase.

How it Works:

Once the user is ready to start the Stage Batch Moisture scheme, a small calculation needs to be done. The user will have to estimate an initial Minutes Per Point (MPP) for the grain that is to be dried. For demonstration purposes, we will set this value to five (5), which is normally a good starting point for most grains. The calculation is used to set the Dry Time for the first batch. After the first batch, the controller uses the initial Dry Timer as a starting place and it will adjust from there to acquire the best MPP.

Below is the equation that is used to calculate the Dry Time.

1. Full batch: N = 1

2. 1/2 - 1/2: N = 2

3. 2/3 - 1/3: N = 3

48 PNEG-1935 Vision Hybrid for Portable Dryers

6. Moisture Control Options

ΔMC = Incoming M/C - M/C setpoint = 21-15 = 6

MPP = 5 minutes

N = 2

Cool Time = 20 minutes

Unload Time = 5 minutes

Now let’s put the values into the equation:

Dry Time =

(ΔMC * MPP) - Cool Time - Unload Time

Dry Time =

(6 * 5)-20-5

Dry Time = = 2 minutes 30 seconds

Here is an example of how to calculate the Dry Time: Let’s say we have a 1/2-1/2 split dryer, so N will equal two. The wet grain has a moisture content of 21%

and we want to dry it to 15%. We will use 5 minutes as our initial guess for the MPP. The Cool Time is set for 20 minutes and the Unload Time is set for 10 minutes. So our variables are as follows:

Now that we have calculated the initial Dry Time, let’s use it. Stop the dryer if it is running. On ce the dryer is stopped, press and hold the Stop button on the control panel for 10 seconds calculate the MPP using the Dry Time that is entered by the user, rather than calculating normally. This should be done the first time you run this process or when you are changing grains and know that the MPP is not the same.

The MPP is constantly being changed to narrow down the ideal MPP value. By holding the “Stop” button as mentioned above, it resets the MPP variable. So say you run the dryer for an entire day and shut it off for the night. This day you calculated the Dry Time u sing the calculation above to give the control a starting point. The next day you come out to the dryer, the MPP value will carry over from the day before and start at that value, unless you press and hold the “Stop” button.

Enter the Dry Time that you calculated (2:30 minutes in our example above), Cool Time and Unload Time. Press the Start button to begin the process. Keep in mind the controller will not adjust the Dry Time for the first couple of batches. The number of batches it takes before it assumes control depends on the number of plenum splits. If you have a 1/3-2/3 split, it will not start changing until the fourth batch.

A “Max Grain Temp” safety is available for this scheme. By enabling this feature, the dryer will shutdown and issue a warning if the grain temperature exceeds the “Max Grain Temp” value.
