TIMER SETTING - To set the Load Timer, observe the
normal time required to fill the wet bin, then rotate the
front dial to set timer to the average refill time plus sev-
eral additional minutes.
NOTE:
The Load Timer can be set to several time
ranges of operation. The timer is factory set in the 60-
minute range mode. With this arrangement, the no. 1
mark on the dial face equals 1/6 of the 60-minute
range or 10 minutes.
UNLOAD AUGER
The UNLOAD AUGER switch has two positions: OFF
or ON.
With switch in the ON position, the auger runs continu-
ously and the meter rolls are controlled by the
Unloading Switch position (Manual/Off/Auto).
With switch in the OFF position, the meter rolls and
auger are stopped.
The UNLOAD AUGER switch energizes the meter roll
safety circuit monitor. This monitor will cause a dryer
shutdown if meter roll rotation is not sensed for a peri-
od longer than three minutes and the METER ROLL
shutdown indicator will be energized.
DRYER OPERATOR LIGHT
LIGHT OPERATION - The dryer operator light is
designed to act as either a dryer monitor signal light, or
a night convenience light.
SWITCH POSITIONS - The three-position switch pro-
vides ON, OFF, or MONITOR operation. When the
switch is set ON, the light will stay energized even
when the dryer is shut down. When the switch is set to
MONITOR, the light will be ON only when the dryer is
operating.
NOTE: The light circuit is 115 volts and is intended for
100 watt bulb operation. Do not install an oversize light
bulb!
HOUR METER
The hour meter is useful in keeping track of seasonal
use of the dryer and determining when service is
required. The hour meter is non-resetting and accu-
mulates hours only when the fan is powered.
PLENUM TEMPERATURE CONTROL
Setting the Plenum Temperature:
A. Push the DISP button once and SP (set point) will be
displayed in the Lower LH corner. See Fig. 3-1.
B. Raise or lower SET POINT to the DESIRED plenum
temperature by pushing the arrowed buttons to
increase or decrease (set-point range is 0-250°F).
C. Push RESET to return to plenum temp display. A set
point should not be in the display. If display is inactive
for 60 seconds, it automatically returns to a plenum
temp display.
The PLENUM TEMP Controller will automatically begin
opening the gas control valve when a flame is proven
and will modulate the control valve to hold the Plenum
set point entered.
METER ROLL CONTROLS
UNLOADING SWITCH
Switch has three positions: MANUAL, OFF, and AUTO.
The UNLOAD AUGER switch must be ON in order for
the Unloading Switch to operate meter rolls. With
Unloading Switch in the MANUAL position, meter roll
speed is controlled by the MANUAL UNLOADING dial.
With switch in the AUTO position, meter rolls are con-
trolled automatically by the Moisture Control unit.
With the Unloading Switch set to Manual, the Moisture
Control can only display grain temperature, but cannot
control meter roll speed. With the Unloading Switch
OFF, the Moisture Control display is also off.
MANUAL UNLOADING DIAL
The Manual Unloading dial sets meter roll speed to a
constant unload rate. Set the desired % unload rate by
watching the Unloading Rate volt meter as the Manual
Unloading dial is adjusted. See Drying Time Tables in
Section 5 for suggested start-up settings.
UNLOAD RATE METER
The UNLOADING RATE volt meter monitors the DC
ARMATURE VOLTAGE on the SCR MOTOR driving
the meter rolls. This voltage represents the %
UNLOAD RATE of the dryer and should range from 7%
to 100% as the unload speed is changed. Be sure to
use the Unloading Rate volt meter as the primary indi-
cator of the % unload rate, as the Manual Unloading
dial setting will be close to but not as accurate as the
volt meter reading.
VARI-TROL MOISTURE CONTROL
Vari-Trol Moisture Control works on the principle that
grain moisture and grain temperature are closely relat-
ed. Monitoring grain temperature, combined with man-
ual testing of the grain's final moisture content, will
