Tip
Unless otherwise advised, it is recommended to start drying grain using the default settings for the timers
and delays. If necessary, adjust these values only after having carefully monitored all phases of the drying
cycle.
To set the timers and delays:
1. Whether in continuous flow or staged batch, click System→Cool (Advanced)→Fan Delay from the
taskbar, and set the following parameter:
Fan Delay — The delay between each fan activation. The fan delay is only available in a multiple-fan
configuration.
A fan startup draws a lot of current from the electrical grid and might cause lights to flicker in nearby
buildings. Multiple fans starting simultaneously can create even greater problems. To minimize the
voltage drop in a multi-fan configuration, set the fan delay to allow fans to start one at a time. This cre-
ates many small voltage drops instead of one big drop, thus preventing possible damage to sensitive
devices that are connected to the same electrical grid.
2. From the submenu pane, click Unload (Advanced)→Cleanout Delay and set the following
parameter:
Cleanout Delay — The length of time that the unload auger and the auxiliary unloading equipment
continue to run once the metering rolls stop. When the dryer is stopped and the cleanout delay is
counting down, pressing Stop on the control panel stops the cleanout delay.
Running the unload auger after the metering rolls have stopped ensures that the unload auger is
adequately emptied.
3. Close the active window. If running in continuous flow mode, go to
step 8
; if running in staged batch,
go to the next step.
4. Click Cool→Cooling Timer from the menu pane, and set the following parameter:
Cooling Timer — The length of time that the fans run to cool the grain. This timer is only available in
staged batch mode.
Tip
If running full-heat operation in staged batch mode, set the cooling timer to zero seconds to bypass
the cooling phase.
5. From the submenu pane, click Cool-Down Time and set the following parameter:
Cool-Down Time — The length of time that the fans run following a shutdown error, except when
shutdowns related to the plenums, high grain temperatures, and fan motor overloads occur; in these
instances, the cool-down time is not in effect. This timer is only available in staged batch mode.
Allowing the fans to continue to run when inconsequential shutdowns occur allows you to keep cool-
ing the grain despite the dryer’s status. Once the shutdown message is cleared, press Start on the
control panel to restart the dryer.
6. Close the active window.
7. From the menu pane, click Unload→Unload Timer and set the following parameter:
