11) Press the reset button for timer changes to take
effect immediately.
12) Set the grain temperature setpoint as follows:
♦
180 degree drying temperature =
100 degree grain temperature setpoint
♦
170 degree drying temperature =
103 degree grain temperature setpoint
♦
160 degree drying temperature =
105 degree grain temperature setpoint
♦
150 degree drying temperature =
108 degree grain temperature setpoint
♦
*140 degree drying temperature =
110 degree grain temperature setpoint
♦
*130 degree drying temperature =
113 degree grain temperature setpoint
♦
*120 degree drying temperature =
115 degree grain temperature setpoint
*When drying at a temperature lower than 150
degrees the grain temperature setpoint on the moisture
control thermostat may require a lower setting at night.
7) The screen should read “STOPPED”. The chamber
high level and the chamber low level should both read
“NO”.
8) Set the dry timer using the following charts for the
specific bin size, fan and heater size, drying tempera-
ture and grain input moisture content.
9) Set the dump timer as follows:
♦
18’ diameter bin = 30 seconds
♦
21’ diameter bin = 33 seconds
♦
24’ diameter bin = 36 seconds
♦
27’ diameter bin = 39 seconds
♦
30’ diameter bin = 42 seconds
♦
36’ diameter bin = 36 seconds
10) Set all other delays and timers as prescribed in the
Electronic Monitoring Control section of this manual.
13) Press the start switch on the dryer control panel.
14) CAUTION! Be sure all personnel are clear of fill
systems. Place the load auger switch on the dryer
control panel to the “auto” position.
15) The fill system(s) should start immediately.
16) When the grain reaches the drying chamber low
level rotary switch the fan and heater(s) should start.
17) When the grain reaches the drying chamber low
level rotary switch reaches the drying chamber high
level rotary switch the fill system(s) should stop.
18) When the dry timer reaches zero the display
should read “TEMP HOLD”
19) When the grain temperature reaches the grain
temperature setpoint the dryer should continue to the
dump cycle.
20) The dump chutes should lower, grain should dump
from the drying chamber into the storage chamber, and
the fill system(s) should start.
21) After the dump cycle the dryer should continue to
the beginning of the next dry cycle.
22) After the fourth dump stop the dryer.
23) Test the moisture of the dried grain.
24) If the moisture of the grain is too high increase the
grain temperature setpoint five degrees for each
additional point of moisture to be removed.
25) If the moisture of the grain is too low decrease the
grain temperature setpoint five degrees for each
additional point of moisture to be added.
26) After the moisture control thermostat is adjusted
decrease the time on the dry timer by one-half. The
dry timer should not be set lower than the amount of
time it takes the dryer to refill after the dump cycle.
27) Restart the dryer. The time on the dry timer
should expire before the grain reaches the temperature
setpoint.
