DRYER CONTROL PANEL
ELECTRONIC
MONITORING CONTROL
SYSTEM
The Electronic Monitoring Control System (Figure 2) controls all tim- ing functions and safety circuit checks. It is designed to simplify dryer operation by providing printed messages and warnings on its liq- uid crystal display (LCD).
TURNING ON THE
ELECTRONIC
MONITORING CONTROL
SYSTEM
Turn the control power switch to on. The monitor will display a copyright message and model number, total running time in hours and minutes and the current time and date. To activate the controller press the reset button.
SETTING THE DRY, COOL,
BATCH AND UNLOAD
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 setting on these three timers is dis- played directly above each timer button. To change the setting of these timers follow these instructions:
1.Press the dry, cool or unload timer button.
2.Press the modify button.
3.Press the increase or decrease 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 timers will return to their initial setting if the reset button is pushed.
SETTING THE OUT OF
GRAIN TIMER
If the dryer runs out of grain while the load auger switch is in the auto posi- tion, 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 percentage of time used by the last load. A second screen will appear with the timer's setting, and may be modified as described in the batch timer section.
