How do I set my moisture

START UP PROCEDURE

ADJUSTING THE MOISTURE CONTROL

1 . Each 5 deg. on the MOISTURE CONTROL will change the output mois-

ture by about 1%. Example: you have 100 deg. set, you are getting

16% corn out, you want 17% corn out, so you would reduce the MOIS-

TURE CONTROL temperature by 5 deg. to 95 deg. and this should

change the moisture out to about 17%. If you wanted the corn to come

out dryer, you would raise the temperature on the MOISTURE CONTROL.

2 . There are 4 sensors that are averaged together for sensing MOIS-

TURE CONTROL temperature, 1 on each side of the dryer in the front,

and 1 on each side of the dryer in the back. They are located about

1/3 of the way up the grain column from the bottom, and in from the

side about 4 inches.

3 . The small lights behind the temperatures on the MOISTURE CON-

TROL indicate the temperature of the grain at this sample point.

4 . The 2 lights in the center are green, the lights to the right or to the left of

these are red.

5 . When the grain temperature has the dryer cycling HIGH and LOW speed

on the green lights the moisture setting is being maintained correctly.

6 . Set the METER ROLL SPEED in relation to the small red lights behind

the temperatures on the MOISTURE CONTROL.

7 . RED lights to the left indicate that the grain at the sample point is too

cool or wetter than desired. With this condition turn the (LOW SPEED)

left pot. to a lower number. This will slow down the meter rolls and dry

the grain longer, warming it up.

8 . RED lights to the right indicate that the grain at the sample point is too

hot or dryer than desired. With this condition turn the (HIGH SPEED)

right pot. to a higher number. This will speed up the meter rolls and

remove the grain quicker, cooling it down.

9 . If the MOISTURE CONTROL switches to LOW and only stays on low

for a minute or two and switches back to HIGH, speed up the (LOW

SPEED) left pot. It is set too slow.

10. If the MOISTURE CONTROL switches to HIGH and only stays on low

for a minute or two and switches back to LOW, slow down the (HIGH

SPEED) right pot. It is set too fast.

11. The MOISTURE CONTROL should stay on HIGH about 50% of the

time and on LOW about 50%, give or take 25%. There is a broad range

that will work. It should be switching low to high and back to maintain

the desired moisture. A control that does not switch, will not maintain

an evenly dried grain moisture, when the incoming wet grain moisture

is varying.

12. When adjusting the meter roll speeds it is better not to change the

speed more than 20 points at a time.
