This screen displays the average dewpoint
over the last hour of run time.
This screen shows the setting of the set-
back feature (see page 4-44). The supervi-
sor password is required to make changes
to this screen. It can be set to OFF,
Temperature, or Manual On. Off turns the
setback mode off, and the dryer will not
change the process setpoint. The tempera-
ture setting tells the control the dryer
should go into setback when the hopper
outlet temperature reaches the setpoint
(screen 27). The Manual On setting tells
the dryer to go into setback now.
This screen shows the setpoint the process
temperature will go to once the control
goes into setback. When the control is in
the setback mode, the LED on the dryer
display beside SETBACK will illuminate.
The actual temperature on the default
screen will still show the actual tempera-
ture measured at the hopper inlet. The set-
point shown on the default screen will still
show the original setpoint.
