2015 Quantum® Controller Manual

IMPORTANT!

If the Dryer has been shut down by the EMERGENCY SHUTDOWN method or by a major alarm, the unloading trough will not go through its normal cleanout cycle. If the Dryer is not going to be used within a few hours, resolve the emergency situation, restart the Dryer, and then follow the Resume Hold Shutdown method to allow the normal trough cleanout and the COOL DOWN cycle to occur. This is especially critical in wet and/or cold operating conditions

HOLD and RESUME Modes

These modes have two purposes. One purpose is to PAUSE the Dryer three (3) minutes to change what grain is filling the Dryer. The second purpose is to SHUT DOWN the Dryer and allow it to go into a COOLDOWN cycle.

The Dryer can be temporarily placed into a HOLD or pause mode by pressing the RESUME/HOLD button on the QUANTUM® Monitor or the red Dryer Control Panel. If the Dryer is restarted within the preset RESUME/HOLD delay time period, the moisture control does not lose its drying profile history, and moisture control continues seamlessly without reinitializing the profile.

The Dryer will continue to run for preset RESUME/HOLD delay time period with only the Fan and Pilot operating. The default setting for this period is three (3) minutes.

To RESUME operation, press the RESUME/HOLD button. If it is not resumed during the preset time delay period, the QUANTUM® transitions to a COOL DOWN mode and turns off the Pilot.
