End-of-Season Shut-Down

The following operational procedure provides a step-by-step guide to shutting-down your dryer at the end of the season. This procedure should be followed and used in conjunction with the Pinnacle 20|20 Controls Manual for HMI touchscreen adjustments.

This shutdown procedure assumes that the dryer will not be put back into operation for an extended period of time and that all of the grain in the dryer will be dried and then subsequently emptied.

1. When the last of the grain to be dried has been put into the dryer, press the Metering STOP button. Once takeaway equipment is clear of grain, press the Takeaway STOP button.

2. Dry the remaining grain for approximately six minutes per point of moisture to be removed.

3. Close the manual hand valves supplying fuel to the dryer. This will ensure the burners will run until all of the fuel in the line has been cleared out. Once the burners are extinguished, from the Controls page on one of the HMI's, press the Burner STOP buttons for each burner.

4. Let the fans continue to run for at least 15-20 minutes to cool the grain in the dryer. Once the grain has been cooled down, shutoff the fans by going to the Controls page on one of the HMI's, and press the Fan STOP buttons for each fan.

5. Set the discharge mode to Manual on one of the HMI touchscreens and set the discharge speed setpoint (%) as high as your takeaway system will allow.

6. On the Remote Cabinet, from the Control page on one of the HMI's, press the Takeaway START button. Once the discharge auger or conveyor (if equipped) as well as customer takeaway equipment are running, press the Metering START button. The dryer is now discharging grain and the discharge rate will be established by the Pinnacle 20|20 Control System. Refer to the Pinnacle 20|20 Controls Manual for more information.

7. Allow the grain to be completely emptied from the dryer.

8. On the Remote Control Cabinet, from the Controls Page, press the Control Power TURN OFF button.

9. Turn the main disconnect located on the High Voltage Cabinet(s) to the off position.

10. Refer to the Maintenance section of this manual for additional information on preparing your dryer for an extended shutdown.
