Overload protection
77
Comfort version
Available as an add-on, the minimum and maximum operating pressure can be
saved. Any pressure between the two saved values can then be set during work.
After connecting the adjusting valve unit to
a control unit on the tractor, the system is
ready to operate with the factory set maxi-
mum and minimum operating pressure. If
necessary, these operating pressures can
be individual adjusted using the dials (2
and 3).
High operating pressure = High plough
base release force
Low operating pressure = Low plough base
release force (soft release)
Increasing the maximum operating pres-
sure:
Turn the dial (2) clockwise.
Reducing the maximum operating pres-
sure:
Turn the dial (2) anticlockwise.
Increasing the minimum operating pres-
sure:
Turn the dial (3) clockwise.
Reducing the minimum operating pressure:
Turn the dial (3) anticlockwise.
While working, the tractor control unit must be switched to float
position, otherwise overload protection is not guaranteed if several
plough bases are released simultaneously.
