pressure, in the event the auxiliary grain unloading sys-
tem stops or becomes plugged. After grain overflow is
removed from the discharge tube and the grain release
hatch falls to its normal position, the device will auto-
matically reset and allow the dryer to be restarted.
The discharge assembly is equipped with a Collect-A-
Sample tube to allow a safe and easy method of
obtaining a grain sample. To operate, simply rotate the
tube; 180° rotation provides maximum discharge.
HINGED FAST-TRIP CLEANOUT
The dryer is factory equipped with a "fast-trip" cleanout
mechanism beneath the unload auger, as shown in Fig.
3-2. The individual fast-trip doors allow easy cleanout
of accumulated materials.
METER ROLL CONTROLS
METER ROLL SELECTOR SWITCH
Switch has three positions: MANUAL, OFF, and AUTO.
The UNLOAD AUGER switch must be ON in order to
operate meter rolls. With switch in the MANUAL posi-
tion, the meter roll speed is controlled by the MANUAL
CONTROL dial on the ASC panel (see Fig. 6-7).
With switch in the AUTO position, meter rolls are con-
trolled automatically by the Moisture Controller.
With the Meter Roll Selector set to Manual, the
Moisture Controller can only display grain temperature,
but cannot control anything. With Meter Roll Selector
set to OFF, the Moisture Controller display is also off.
MANUAL UNLOAD CONTROL DIAL
The Manual Control dial sets meter roll
speed to a constant unload rate. Set the
desired % unload rate by watching the %
Unload Rate volt meter as the Manual
Control dial is adjusted. See Dryer Tables
in Section 5 for suggested start-up settings.
SERVICE TIP: Open cleanout doors at end of season and remove debris.
Doors may be left open during the off season for better drainage.

% UNLOAD RATE (METER ROLL) VOLT METER
The % UNLOAD RATE volt meter monitors the DC
ARMATURE VOLTAGE on the SCR MOTOR driving
the meter rolls.
UNLOAD RATE of the dryer and should range from 7%
to 100% as the unload speed is changed. Be sure to
use the % Unload Rate volt meter as the primary indi-
cator of the % unload rate, as the Manual Control Dial
setting will be close to but not as accurate as the volt
meter reading.
VARI-TROL MOISTURE CONTROL
The Vari-Trol Moisture Control works on the principle
that grain moisture and grain temperature are closely
related. Monitoring grain temperature, combined with
manual testing of the grain's final moisture content, will
allow the operator to determine the proper tempera-
ture/moisture relationship.
temperature control assembly on the ASC panel, the
operator can view the current grain temperature and
set the desired grain temperature (setpoint), in the
manner described as follows.
