4.6.3 Hydraulic Plumbing
WARNING!
From this point in the installation the
booms will be inoperative until the
electronics are fully installed.
You must ensure there are no other
orifices present in the circuit
between the NORAC valve block and
the boom cylinders. Some sprayers
have orifices in the fittings at the
boom cylinders.
1. After the NORAC valves are mounted, the
hydraulic hoses and fittings can be plumbed.
The plumbing for the hydraulic circuit is
shown schematically in Figure 3.
2. Connect the NORAC supplied hoses (H03)
to the Pressure (P) and Tank (T) ports on
the NORAC valve block (V01). Route both
of these lines to the sprayer valve block.
3. Tee H03 in to the Pressure and Tank ports
available on the side of the sprayer valve
block with F02 and F03.
4. Connect the existing hoses that run to the
boom tilt cylinders to the NORAC valve
block with the NORAC supplied fittings
according to Figure 3.
a) The “raise” lines must be connected to
the "B" ports of the NORAC valve block.
The ports on the sprayer block must
then be capped with F05.
b) The "A" ports of the NORAC block
must be connected to the “lower” lines
of the cylinders. The ports on the
sprayer block must then be capped with
F05.
