Autoflow Operation
Dryer Status
By viewing the display on the dryer control
panel the user can quickly determine what mode of
operation the dryer is in, what cycle the dryer is in,
the location of grain relative to the drying chamber
rotary switches, and the current status of the dryer.
The Electronic Monitoring Control System flashes
the current status of the dryer on the display on the
dryer control panel. When the system is running,
information about the operation of the dryer and
the location of grain can be obtained with a quick
glance at the dryer control panel. The displayed
dryer conditions are as follows:
Batch Mode
When the display on the dryer control
panel reads “batch mode”, the dryer has been
programmed to operate as an automatic batch
dryer. When operating as an automatic batch dryer
all the grain in the drying chamber is dumped into
the storage chamber during the dump cycle, and a
cooling cycle is available after the dry cycle. This
is not the standard mode of operation. The user
must enter the set-up mode to change the dryer
model from AB1 or AB2 to AF1 or AF2, to
change from Autobatch to Autoflow.
Auto Mode
When the display on the dryer control
panel reads “auto mode”, the dryer has been
programmed to operate as an automatic staged
batch dryer. When operating as an automatic
staged batch dryer, only the driest third of grain is
removed from the drying chamber during the
dump cycle, and once the drying process starts it
does not stop until the dryer is stopped. This is the
standard mode of operation.
Grain High Level YES
When the display on the dryer control
panel reads “grain high level yes”, the grain in the
Grain High Level NO
When the display on the dryer control
panel reads “grain high level no”, the grain in the
drying chamber has not reached the drying
chamber high level rotary switch. If the load
auger switch on the dryer control panel is in the
“on” or “auto” position, the fill system(s) should
be running.
Grain Low Level YES
When the display on the dryer control
panel reads “grain low level yes”, the grain in the
drying chamber has reached the drying chamber
low level rotary switch. If the fan switch on the
dryer control panel is in the “auto” or “on”
position the dry timer begins to count down and
the dry cycle begins.
Grain Low Level No
When the display on the dryer control
reads “grain low level no”, the grain in the
drying chamber has not reached the drying
chamber low level rotary switch and the drying
process has not started.
Stopped
When the display on the dryer control
panel is flashing “stopped” the dryer is not
running. The set-up mode can be entered into
when the dryer status is “stopped.”
Purging
When the display on the dryer control
panel is flashing “purging”, the dryer is running,
drying chamber has reached the drying chamber
high level rotary switch. If the load switch on the
dryer control panel is in the “auto” position, the fill
system(s) should be stopped or in the process of
stopping.
