Staged Batch Check
The following test must be done with grain in the dryer or with the Air switch turned OFF as noted in the
Fan switch section
on Page 43 . To check the staged batch operation, turn the Control Power switch to the
ON position. Open the main fuel supply valve at the tank on an LP dryer or open the valve in the fuel supply
line on a natural gas dryer. Turn the Drying Mode switch to the staged batch position. Turn ON the electric
shut off valve to allow fuel flow to the dryer. Turn the Load switch to AUTO, the Unload switch to 1 Speed
and the fan and burner to ON. Push the Dryer Power Start button and the controller will sequentially start
all dryer components in their proper order. If any switches are not in their correct position for staged batch
operation, the dryer will indicate improper switch position and will not start until the switches are in the
proper position. After starting, all batch timers will time down in sequence. When the unload cycle is
complete, the timers will automatically reset to their original settings and start the dryer timer again.
NOTE: If the dryer is empty, the burner does not operate. The fans cannot create enough static pressure
to engage the Air switch. You will receive a “no airflow” message. To start the dryer when it is low
on grain, the Airflow switches must be turned OFF. Switching Dip Switch number eight (#8), on the
back of the computer control board, to ON turns the Air Switch OFF.
Stopping Dryer Operation
To stop operation of the dryer, push the Dryer Power Stop button. The fan, burner and all augers will
stop immediately.
Dryer Shutdown
To shutdown the dryer, first close the fuel supply valve at the tank or valve along the fuel line. If the burner
is operating, let the dryer run out of fuel and it will shutdown automatically due to loss of flame. Close the
fuel valve at the dryer and press the Dryer Power Stop button. Turn OFF the safety disconnect handle on
the front of the power box and turn OFF the main power to the dryer.
Emergency
In case of emergency, push the Emergency Stop button located at the bottom of the upper control box.
(See Page 9.)
WARNING
Dip switch number eight (#8) must be turned back to the OFF position after this
test is complete or no air testing will occur.
