This screen shows the actual return air
temperature measured at the inlet to the
process blower. If the optional aftercooler
flow control is installed, a setpoint will be
displayed on this screen as well. The (+) or
(-) buttons can be used to change the set
point. Holding the (+) or (-) buttons in
will allow the number to ramp up faster
the longer the button is held.
This screen is used to set the dryer to auto
start. The dryer must be on but not run-
ning to set auto start. The value shown is
the countdown time setpoint. It is
adjustable from 0.1 hours to 150 hours.
Once the countdown time is set, press the
“START” button. The display will show
ON to tell the operator that the auto start is
ON and counting. The auto start LED on
the display also flashes green when the
auto start is armed and counting down.
The LED will turn solid green when the
dryer starts. The dryer will begin operat-
ing when the control has finished counting
down.
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 signal
the dryer will display a passive alarm.
The range for this time setting is 5 to 20
seconds.
