Operational Adjustment of Harvest Performance Monitor I

Precondition: combine harvester is adjusted to peak efficiency.

While threshing, adjust potentiometers (A) and (B) one after the other so that the needle on display unit (C) moves to the center of the green sector (X) when there are grain losses.

I - Set potentiometer for straw walker losses:

· Use potentiometer (A) to bring the needle into the green sector (X).

II - Set potentiometer for cleaning shoe losses:

· Use potentiometer (B) to bring the needle into the green sector (X).

Grain losses vary all the time. This means that the sensors on the cleaning shoe and straw walkers will transmit signals of varying intensity to the display unit. If these signals rise or fall in relation to the preset value, the needle on the display unit will swing to the left or right.

NOTE: If no losses occur (and therefore none are displayed) even at maximum sensitivity, leave the two potentiometers (A) and (B) set no higher than the "two o'clock" position.
