2. Manual Mode

Manual Mode – MAN – is a simple time-based pro-

gram in which drying times are set with a percentage 
value that shows how much of the time the feed-out is 
active.
 

Example: If MAN is set to 10%, the feed-out is run-

ning 10% of the time and inactive 90%. If the value is 
set to 50%, the feed-out will run and be idle in a 50/50 
relation, and so on.
 

It is recommended to move the dried commodity 

to a wet silo so that damp cereals can continuously be 
fed into the dryer. Check the moisture content of the 

dried product regularly. If the outgoing grain is too wet, 
lower the setting on the panel. Is the item instead is too 
dry, raise the value. 
 

When the desired moisture content is reached, 

press “Auto Set “ after which the system will automati-
cally set a value corresponding to the one used in 
Manual mode.
 

If the “Auto” button is pressed directly without pre-

setting, the control automatically switches to the last 
setting previously used by the auto function.

Press “Man”

Step 1

PV

: Shows the signal from the sensor.

Man

: Shows the percentage set.

Feed Out

: Lights up yellow when output is 

active.

 : Decreases the set percentage (drier item).

+

 : Increases the set percentage (wetter item).

Auto

: Go to the Auto screen to set the control 

on the auto value that was used the last time 
auto mode was used.

Auto Set:

 To go to Auto, where the controller 

loads a new auto value with respect to the 
signal from the sensor (PV) and the percent-
age used when pressing the button.

Main

: To go to the Home screen.

Step 2

NOTE:

 When The dryer is empty, the signal value “PV” should be 

4.00. If it is below 3.70 or above 4.30, the equipment needs service 
and calibration.
