Daily Operations
The following operational procedures provide a step-by-step guide to starting-up and shutting-down your dryer. These procedures should be followed and used in conjunction with the Pinnacle 20|20 Controls Manual for HMI touchscreen adjustments.
Daily Shut-Down
This shutdown procedure assumes that the dryer will be put back into operation within 24-48 hours. If the grain drying operation will not resume within 24-48 hours, it is suggested that the dryer be emptied and the grain placed back into the appropriate storage. Grain dryers are not designed to be grain storage devices. Once all the grain has been dried, it needs to be emptied from the dryer and stored appropriately. Grain stored in a dryer for more than one week may cause damage to the machine. For an end-of season shutdown procedure, see the End-of-Season Shut Down portion of this section of the manual.
On the Remote Cabinet, from the Controls Page on one of the HMI's, press the Metering STOP button. Once takeaway equipment is clear of grain, press the Takeaway STOP button.
On the same Controls page, press the Grain Fill STOP button. The grain fill system will now be shutdown and your fill equipment will no longer be commanded to run.
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.
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 pressing the Fan STOP buttons on the Controls page.
From the Controls page, press the Control Power TURN OFF button.
Turn the main disconnect located on the High Voltage Cabinet(s) to the off position.
Daily Start-Up
This start-up procedure assumes that the dryer has recently been in operation and is full of grain. For a first time start-up, see the Daily Start-Up procedure portion of this section of the manual.
Turn the main disconnect located on the High Voltage Cabinet(s) to the on position.
On the Remote Cabinet, go to the Controls page on one of the HMI's and press the Control Power TURN ON button.
On the same Controls page, press one of the Fan START buttons. The fan should start immediately. Repeat this procedure for all of the fans, allowing time for each fan to get up to speed before starting the next.
Set the plenum temperature setpoints for each plenum. Refer to the table at the end of this section for suggested drying temperatures based on model number and grain type. Setting the plenum temperature can be done on the HMI touchscreens as explained in the Pinnacle 20|20 Controls Manual.
Open all manual gas supply valves so that fuel is free to flow to the burner once the gas valves controlled by the ignition system are opened.
On the Remote Cabinet, from the Controls page on one of the HMI's, press the Burner START button. After a 15 second delay, the burner should be lit. Repeat for all necessary burners.
On the Remote Cabinet, from the Grain Fill Settings page on one of the HMI's, uncheck the Fill From Empty box. The grain fill system will now operate automatically as outlined in the Grain Fill Settings portion of the Pinnacle 20|20 Controls manual.
Refer to the Pinnacle 20|20 Controls Manual for the requirements prior to starting the dryer's discharge. At a minimum, set the discharge mode to Manual on the HMI touchscreen and set the discharge speed setpoint (%) in accordance with the table that follows.
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.
