This screen shows the amount of time the
conveying blower will run. Based on the
position of the demand sensor in the mate-
rial receiver, this time may need adjusted.
The time should be set for the time it takes
to satisfy the demand sensor + 1 second.
If the MDC tries to load three consecutive
times without satisfying the demand sig-
nal, the dryer will display a passive alarm.
These control screens are not used for the
W 150-400 DC-2.
This screen will show the actual dewpoint
of the process delivery air measured after
the desiccant wheel and before the process
heater. The dewpoint control will automat-
ically adjust the regeneration temperature
to maintain the dewpoint setpoint.
Dewpoint control is not active with -40
°F
{-40°C} setpoint.
NOTE: Dewpoint actual will not be live for
approximately 5 to 8 minutes.
This is the dryer MAIN MENU. It can be
located by pressing the MENU key while
at the DEFAULT screen. By pressing the
Select Category buttons under the titles,
the user goes to STATUS screens, SETUP
screens, or DIAGNOSTIC screens.
