Control Function Descriptions
(continued)
This screen is the Setback Temperature
Band screen. This temperature is the
amount the return air out of the hopper has
to drop below the activate setback temper-
ature (Screen 10) before the original
process temperature is restored. For exam-
ple, if the activate setback temperature was
180°F {82°C} and the dryer was in set-
back. The actual temperature measured at
the outlet to the hopper which has a 20°
Setpoint (Screen 23) would have to drop
below 160°F {71°C} to restore the original
process setpoint.
This screen is the Aftercooler Flow
Control Enable screen. By pressing the (+)
or (-) keys, the setting can be changed.
With this off or disabled, the dryer will not
open the flow control valve and try to con-
trol the return air temperature. There will
also be no set point value on Menu number
3, Screen 7.
