The feed methods are:
1. Fast forward (22, range 0 – 255 mm).
2. Slow forward (23, range 0 – 255 mm).
3. Fast backward (24, range 0 – 255 mm).
4. Slow backward (25, range 0 – 255 mm).
NOTE!
Each feed method will be used, if the distance is more than 2 x the
braking distance of this feed. If for instance the braking distance of fast
feed is 200 mm, the tree is fed with this feed method, if the distance to
the desired length is more than 400 mm, otherwise the tree is fed with a
slow feed method.
−
When taking the equipment into use or if the expected braking
distances for some reason have changed so that it seems difficult to
run to the correct length, the system has to ”learn” the new settings in
the following way:
1. Give the expected braking distances the following values:
−
Fast forward
= 200 mm
−
Slow forward
= 20 mm (Low speed)
−
Fast backward
= 150 mm
−
Slow backward
= 15 mm (Low speed)
2. Select
overrunning method
0 (no overrunning).
3. Set a small
crosscutting tolerance
(for instance 10 mm).
4. Set the
number of trials
(setting 20) as high as necessary (for
instance 100).
5. Select
feed method
(2) for automatic feed (value 1).
6. Make the
low speed feeding pulse
(K38) as small as possible
(for instance 10). If proportional pump is in use, set the
low
speed
(K7) small (for example 10 – 30).
7. Increase the number of revolutions to the level used in normal
tree handling.
8. Take a readily delimbed tree into the grapple and saw a disk at
the butt end.
9. Press one of the preselection lengths on PS (for instance 4.60
m), and the harvester will search for that length.
10. Press another length on PS (for instance 4.30 m), and the
harvester searches for that length.
11. Repeat items 9 and 10, i.e. run the tree back and front several
times, until the right length is always found rapidly.
12. Set the values that were changed in items 3 – 6 above to the
normal values again, i.e. set them back to the original values.
