SETTING THE LOAD AND

UNLOAD DELAYS

The load delay is used to delay the starting of the load auger when the dryer is unloading to prevent the load auger from starting and stopping. The unload delay is used to control the amount of time the unload au- ger runs after the metering rolls stop to allow for auger cleanout. Both the load and unload delays are set us- ing the same procedure as the tim- ers. The aux 1 and aux 2 delays are presently not being used.

UTILIZING THE

BUSHEL COUNTER

When operating the dryer the LCD display will show the dryer mode of operation on the first line, the bush- els per hour or the metering roll rpm on the second line and the total

bushels dried on the third line. By pressing the bph/rpm/total bu but- ton the second line will alternate between the metering roll rpm's or the bushel per hour rate. The to- tal bushels dried reading is the to- tal since the bushel counter was last reset. To reset the bushel counter, press and hold the reset button for five seconds. Press the enter button through the date and time settings, and follow the in- structions displayed on the LCD for resetting the counter.

In the batch mode, the first line of the LCD display tells which timer is being used, and the second line switches between total batches, unload rpm or total bushels. The third line indicates total dry time, and the fourth line is time remain- ing on the timers.

DRYER SAFETY CIRCUIT

The Electronic Monitoring Control System continuously checks all safety circuits on the dryer, and will automatically shut the dryer down should a problem occur. The cause of the dryer shutdown will be dis- played on the LCD display, and a beeper will sound on the controller. To restart the dryer after a safety shutdown, first correct the reason for the shutdown, and then press the dryer power stop button to reset the circuit. Press the start button.

The Electronic Monitoring Control System stores in its memory the time, date and cause for the last 25 dryer safety shutdowns. To review this in- formation, hold the reset button in for five seconds. The procedure for re- viewing the safety circuit shutdown log will be displayed on the LCD display.
