4.2 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, the 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 UC4.5 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.
