4.1.2 Hydraulically Teed Installation
Hydraulically Teed Installation must be
done if the sprayer valve block does NOT
have individual electrical wiring to control
each boom function. For example, your
sprayer may have signal lines to select a
boom (left, right and main) and separate
electrical signals for the direction (up and
down).
For Hydraulically Teed Installation,
MANUAL mode of the UC4+ Control
System does not operate the same as with
Electrically Teed Installation. Electrically
Teed Installation will allow the operator to
trigger individual boom movements into
MANUAL mode while maintaining
AUTO mode for the other boom
movements (e.g. left boom can be in
MANUAL mode while right boom is still
in AUTO mode). Hydraulically Teed
Installation does not support this function.
If the operator triggers any boom
movement, the whole NORAC system will
convert to MANUAL mode.
Hydraulically Teed Installation
may also be done if the operator
wants the existing sprayer valves,
instead of the NORAC valves, to
operate the booms when the
NORAC system is in MANUAL
mode.
Figure 6 and Figure 7 show the
Hydraulically Teed Installation in
its general installation
configuration.
