11 Fieldwork 11.7 Separation 67087 82502 11.7.3 Adjusting the separation performance monitor display The cleaning and separation performance monitor allows the operator to make full use of the capacity of the machine. The display (3) allows the operator to determine how fast the machine can be driven without the reasonable grain loss limit being exceeded. 2 2 Grains lost over the back of the combine with the straw fall onto the sensors (2). The excited pulses are visual- ised by the meter lights of the display (3). The sensitivity of the separation display can be set depending on the properties of the crop (straw mois- ture, green part, grain shape, leaf content of straw).
19647 39 Adjust the separation performance monitor sensors. Set the sensitivity of the separation display and the desired individual grain loss limit at switch (4). 3 The display reacts more sensitive / less sensitive, depending on the adjusted set value. Check the grain loss limit. Proceed as follows: Prepare fieldwork. Set the machine depending on the crop. See threshing chart. Engage front attachment. Engage the threshing mechanism. Drive the machine into the crop at the speed appropriate for the crop. Stop the machine when the forth to fifth light of the meter light (3) lights up constantly after a sufficient distance has been covered. Check the losses in the swath.
If loss is at an acceptable level, continue operation with selected setting. When losses on the straw walker are too high, increase the gauge sensitivity by about half to one step, using switch (4). Now adjust forward speed until the fourth or fifth light in the meter light (3) lights up again. When excessive losses on the straw walker con- tinue, check the machine setting regarding concave clearance, drum speed and deflector cur- tain setting. 4 40 DOMINATOR 150 / 140 19558 4 3 41 DOMINATOR 130 19412 If the loss rate, indicated by the fourth or fifth light in the meters, is acceptable, the capacity of the combine is fully utilised at this forward speed.
