The DEW POINT value will give you a reading of what the actual process air dew point is.
The area in the lower left portion of the touch screen conveys two lines of information relating to the overall operation of the dryer.
The following is a list of typical machine/dryer summary status line text messages:
1.Dryer Off
2.Left Bed In Process
3.Right Bed In Process
4.Valve Changing Position
5.Autostart Timer Enabled
6.Autotune in Progress

10.Left Bed Ready
11.Left Bed Failure
12.Left Bed Process Failure
13.Right Bed Heat
14.Right Bed Cool

The START BUTTON allows the user to stop and start the dryer manually. When the start button is pressed, the dryer begins to operate. The text in the button will change from START to SHUTDOWN. The next time the button is pressed, the dryer will go into a sequence shutdown and the button text will change to RESTART. The process heater will shut off, the current bed regeneration will be completed and then the blower will stop. If sequence shutdown is not desired, turning the POWER SWITCH off will turn off all components of the dryer immediately and the optional conveying system will be turned off also.
When the button shows ALARM, the process temperature is too hot to start the dryer. When the process air temperature falls below the setpoint, the button changes to either START or RESTART, you may begin dryer operation.
