6. Competitor/Dri-Tek Test Firing Before the dryer is filled, thoroughly inspect the unit and check the operation of the dryer as follows. Inspect the Metering Rolls Figure 6A 4" Meter Roll Figure 6B 7" Meter Roll 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.
6.
6. Competitor/Dri-Tek Test Firing 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.
6. Competitor/Dri-Tek Test Firing 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.
6.
6. Competitor/Dri-Tek Test Firing Staged Batch Check The following test must be done with grain in the dryer or with the Air switch turned OFF as noted in the Fan switch section on Page 43. To check the staged batch operation, turn the Control Power switch to the ON position. Open the main fuel supply valve at the tank on an LP dryer or open the valve in the fuel supply line on a natural gas dryer. Turn the Drying Mode switch to the staged batch position.
7. Vision Test Firing Dryer Pre-Season Checks Before staring the drying for the first time in a drying season, perform the following checks. If any of the checks fail to produce the stated result, the customer should consult the dealer. Do not attempt to use the dryer unless all the pre-start checks have been successfully completed.
7. Vision Test Firing 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.
7. Vision Test Firing 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. All power should be switched OFF and locked out before attempting to reverse WARNING the connections.
7. Vision Test Firing Approximate setting should be: LP Gas Natural Gas High-Fire 6-15 PSI (41-102 kPa) High-Fire 6-10 PSI (41-69 kPa) Low-Fire 2-6 PSI (14-41 kPa) Low-Fire 1-3 PSI (7-20 kPa) If the burner remains on high-fire and does not cycle, increase the regulator setting, in order to reach the plenum setpoint. If the burner remains in low-fire and does not cycle, slightly decrease gas pressure with the low-fire adjustment screw on the cycle solenoid.
7. Vision Test Firing Watch gauge for pressure Low-fire needle valve Relief valve Supply line ball valve (high-fire) Regulator Figure 7B Natural Gas (NG) Pipe Train Dryer Shutdown To shutdown the dryer: 1. Close the fuel supply valve at the tank or valve along the fuel line. 2. If the burner is operating, let the dryer run out of fuel and it will shutdown automatically due to loss of flame. 3. Close the fuel valve at the dryer and press the Stop button. 4. Turn OFF the control power. 5.
8. Competitor Dryer Operation Continuous Flow Operation Standard electrical safety practices and codes should be used when working with a dryer. Refer to the National Electric Code standard handbook by the National Fire Protection Association. A qualified electrician should make all wiring installations. Always disconnect and lock out power before working on or around dryer. WARNING Full Start-Up Check This start-up procedure assumes the following: 1.
8. Competitor Dryer Operation Staged Batch Operation 1. Turn the Control Power switch to ON. 2. With load, unload, fan and burner turned OFF, turn the Drying Mode switch to continuous then push the Dryer Power Start switch to arm the safety circuit. Turn the Load switch to ON and fill the dryer with grain. The load auger will stop when full if the Load Tilt Switch is installed and set properly. 3. Turn the Drying Mode switch to staged batch. 4.
8. Competitor Dryer Operation 11. If the dryer is being operated in all heat, move the Fan switch to the ON position. In this position, the fan will run continuously during the dry, cool and unload stages of the staged batch operation. If the dryer is being operated in the dry and cool mode, the preferred position for the Fan switch is the ON position, so the fan will run continuously and continue to cool the grain during the unload operation.
8. Competitor Dryer Operation 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.
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.
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.
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%.
9. Vision/Dri-Tek Dryer Operation Setting the Temperatures To adjust the temperature setpoints, touch the button at the bottom of Default Operation Screen. The “Select Temperature Setpoint to Modify” Screen will be displayed. See Vision Manual for instructions on how to set the temperatures.
9. Vision/Dri-Tek Dryer Operation Continuous Flow Drying Mode Using Regulation of Grain Temperature Full Heat Continuous Flow Operation This section begins with Step 7 and it is assumed that Step 1 through Step 6 in the start-up procedure described on Page 58 have been completed. For this operation procedure we will say that incoming grain moisture content is 25% and ten points of moisture removal is our goal. 7. Touch the Setup button at the bottom of the Default Operation Screen.
9. Vision/Dri-Tek Dryer Operation 13. Refer to PNEG-1650/PNEG-1651 for the full heat chart settings that correspond to the model of dryer. Note the settings for initial moisture, moisture removed, approximate dry time, 1 Speed, 2 Speed low and 2 Speed high. Select the line that has the initial starting moisture. These are the settings that will be referred to during this start-up procedure. 14. Run the fans and burners for approximately 10% longer than the estimated dry time for the incoming moisture.
9. Vision/Dri-Tek Dryer Operation Figure 9C 19. With the Unload Auger switch in the AUTO position, the moisture control is active. Select the M/C button at the bottom of the Default Operation Screen. When the “Modify Temperature Setpoint” window appears, set the temperature to approximately 105°F. Let the dryer run on these settings before adjusting moisture or meter roll settings. These settings will not dry the grain exactly as desired, but they will serve as a good starting point.
9. Vision/Dri-Tek Dryer Operation Dry and Cool Continuous Flow Operation This section begins with Step 7 and it is assumed that Step 1 through Step 6 in the start-up procedures described on Page 58 have been completed. For this operation procedure we will say that incoming grain moisture content is 25% and ten points of moisture removal is our goal. 7. Touch the Setup button at the bottom of the Default Operation Screen.
9. Vision/Dri-Tek Dryer Operation 14. Run the bottom fan (to be used for cooling later) and heater(s) for, approximately 20 minutes. This will start the bottom drying, so it can cool before discharging grain. 15. Run the fans and burners for approximately 10% longer than the estimated dry time for the incoming moisture. Example: Ten points removal is approximately 60 minutes. -10% of 60 minutes is 6 minutes, so run the fan/heaters approximately 66 minutes. 16.
9. Vision/Dri-Tek Dryer Operation Figure 9G 20. With the Unload Auger switch in the AUTO position, the moisture control is active. Press the M/C button at the bottom of the Default Operation Screen. When the “Modify Temperature Setpoint” window appears, set the upper temperature to about 130°F.

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.
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.
11. Service 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 strokes 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.
11. Service 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.
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.
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.
11. Service 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.
