SETTING THE DRY (16), COOL (17) AND UNLOAD (18) BATCH TIMERS

These switches are used to set the cycle times in the STAGED BATCH DRYING MODE only. The DRYING MODE switch must be in the STAGED BATCH position. The cur- rent settings on these three TIMERS are displayed directly above each TIMER button. To change the set- ting of these TIMERS follow these instructions:

2.Press the MODIFY button.

3.Press the INCREASE or DE- CREASE button to adjust the settings.

4.Press the ENTER button.

During operation the remaining time on each TIMER is displayed on the screen. If the power goes out or

if the dryer is stopped, these times are saved by the controller. When the dryer is restarted the TIMERS will continue timing down. The TIM- ERS will return to their initial settings by pressing the RESET button.

SETTING THE OUT OF

GRAIN TIMER (19)

If the dryer runs out of grain while the LOAD AUGER switch is in the AUTO position, the OUT OF GRAIN TIMER automatically shuts OFF the dryer after the period of time preset on the TIMER. When pressed, the display will show the amount of time left on the TIMER and the percent- age of time the last load expended. A second screen will appear show- ing the TIMER'S setting and will al- low the operator to modify it as de- scribed for setting the BATCH TIM- ERS.
