The main systems of Row-Pro™ consist of:
1. An air compressor system:
one 12V air compressor
with air tank , two
extension cables , and one fuse assembly .
2. A load sensing system:
DPLCM (Down Pressure Load Cell Module)
and
the load cells .
3. An adjusting system:
valves
and air cylinders .
Load Cell, DPLCM and Valves
The DPLCM and valves are mounted together on
a plate and are connected to the DICKEY-john
®
wiring
harness .
The load cell located on the center most opener is
attached to the DICKEY-john
®
wiring harness at .
Four leads on the DICKEY-john
®
wiring harness
connect to the valve sets . There is one pair (one air
intake, one exhaust) for each valve.
Note: For single row planters:
There is one load cell and one valve set per
each opener section located at mid section.
Note: For twin row planters:
There are two load cells and two valve sets per
each opener section located on the long center row
unit of the section.
The wiring harness connects to the planter at
connector ends which ties into the IntelliAg
®
system.
Electrical System
Place the compressor as close to the tractor battery as
possible using the least amount of electrical connections
as possible to minimize voltage drop. The battery
connection is equipped with one large 60 amp spade
fuse (automotive type).
Note: If your tractor has an on-board engine driven
compressor capable of 150 psi, it can be used
instead of the one supplied with the planter. Hook
the on-board compressor to the air tank with lines
provided.
