Shutting Down the Dryer
1. Turn off the conveying system supplying the drying hopper and/or machine. Press the shutdown
button for the dryer to complete its cycle.
2. When processing is complete, close the hopper slide gate and shut down any in-line companion
equipment, such as the aftercooler.
3. If the dryer is shut down using the shutdown button on the dryer status screen, the process heater
will shut off and the bed regeneration process will be completed. When the dryer is started at a later
date the process air will be directed through the bed that was regenerated last.
4. If the dryer control switch is turned off without using the dryer shutdown feature, the dryer
and the on board conveying system will stop immediately. When the dryer is started at a
later date, the process air will be directed through the last bed that was being used when the
dryer control switch was turned off. If a bed was being regenerated when the dryer control
switch was turned off, the regeneration process would begin over again on that same bed.
