The following operational procedure provides a step-by-step guide to starting-up your dryer. This procedure should be followed and used in conjunction with the Pinnacle 20|20 Controls Manual for HMI touchscreen adjustments.
This start-up procedure assumes that the dryer has not recently been in operation and is not full of grain. For a repeated daily start-up, see the Daily Start-Up procedure portion of this section of the manual.
Adjust the high limit switch setpoint to approximately 40 deg F above the desired plenum temperature as explained in the High Limit portion of this section of the manual. This should be done for all plenum high limit switches.
Set the grain fill timers as explained in the Settings Chapter of the Pinnacle 20|20 Controls 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.
On the Remote Cabinet, go to the Grain Fill Settings page on one of the HMI's and check the "Fill From Empty" box. Next, press the Grain Fill START button. The level auger, if equipped, should start immediately and your grain fill equipment should be commended to deliver grain to the dryer.
Once the dryer is full of grain, adjust each of the air pressure switches so the air pressure light illuminates as explained in the Air Pressure Switch portion of this section of the manual.
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.
Allow the dryer to warm up and dry the initial load of grain as a batch operation or be prepared to cycle the first batch back into the wet bin so that it may be processed through the dryer again on a continuous flow basis.
On the Remote Cabinet, from the Grain Fill Settings page on one of the HMI's, confirm that the Fill From Empty box is unchecked. This should automatically uncheck once the dryer is full. 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.
