ALARMS

(Alarm History Screen)

This screen allows the operator to review the number and type of issues that the dryer has encountered during its operation.

Problems can be viewed by Date, Hour, and Comment.

To view alarms not visible on the screen, press the DOWN button.

To return to a particular alarm, press the UP button to scroll upward in the alarm history.

Pressing DRYER in this screen will take the operator to the DRYER STATUS of the system.

Pressing MAIN will take you to the main screen.

At this point, the operator can return back to the DRYER MENU or MAIN MENU by touching the appropriate button on the screen.

AUTOTUNE

(Process AutoTune Screen)

This screen allows the operator to automatically tune the process air temperature control algorithm to a specific drying application. The autotune sequence should be initiated if the user feels there are unacceptable fluctuations in the process air temperature. The calculated P, I, and D variables are shown for reference purposes.

The autotune feature can be activated by pressing the START/STOP button located in the center of the screen. After autotuning is done, it will automatically stop and give new P, I, and D variables.
