VRI-2 VRI Operation/Installation Manual
General Safety Instructions
WARNING
Lock Out/Tag Out: Disconnect all sources of energy and lock out machine before doing any
maintenance or repairs to the machine. Proper Lock Out procedures will prevent the energy source from
starting the machine or allowing parts to move unexpectedly as well as prevent the machinery from being
accidentally turned on or restarted. Shut off and Lock Out all sources of potential or kinetic energy. These may
include, but are not limited to, electrical, mechanical or hydro energy sources.
Lock Out is a procedure used for placing an actual locking device on the power source, preventing unexpected
start up or accidental release of energy. Lock Out is the preferred method of accident prevention.
Tag Out procedure is used when the power can not be disconnected. Tag Out does not shut down the power
source, Tag Out only provides a warning about the danger of activating the machine.
Never try to operate machinery that is locked out or tagged out. Never attempt to remove these locks or tags on
machinery. Doing so will result in injury to personnel working on the machine. Only the initiator of the Lock Out or
Tag Out procedure may remove locks and tags.
Sometimes it may be necessary to energize the system to test or position equipment during maintenance or
repair. Such application must be performed only by a qualied technician and all Lock Out removal steps must be
followed before power is turned on.
WARNING
Main Disconnect: The main power disconnect is located at the main service breaker or
generator. The disconnect at the panel is not the main disconnect. A fuseable service disconnect device
must be placed previous to this panel with the fuses sized for the load being supplied and installed in accordance
to NEC codes.
It is important to understand the differences between the Pivot Enable switch (if installed), High Voltage On/Off
switch and the service breaker On/Off throw switch.
The power company service disconnect provides the ability to turn off or return full service to the equipment from
the power company service line. This switch must be turned off and locked out when performing maintenance and
repairs on the system.
The High Voltage On/Off provides the ability to turn off or return power to the equipment from the service discon-
nect. This switch must be turned off and locked out in conjunction with the service disconnect switch. The High
Voltage switch only disconnects the power in the control panel, as energy is still coming in from the main power
line.
The Pivot Enable switch (if installed) provides power to the system controls. When enabled, the entire system and
the controls will power up. When turned off, the controls and system will not be energized. However, there will be
power in the panel circuitry. The Pivot Enable switch is NOT a disconnect and should not be treated as such.

Introduction
What is Variable Rate Irrigation?
Variable Rate Irrigation (VRI) is a controller added to a mechanized irrigation system. This controller regulates the
amount of water to be applied along any part of the irrigator path.
Past irrigation practices attempted to maximize efciency using blanket irrigation, where water is applied as
uniform as possible under the length of irrigator. This has not been found to be the most efcient way to irrigate
by today’s standards. Variables such as drainage, soil texture and type, different crop requirements, and in some
cases, several acres within a eld would require no watering at all but still lie in the irrigator’s path; all of these situ-
ations can produce undesired results with blanket irrigation.
With Variable Rate Irrigation, the correct quantity of water can be applied in the precise location where it’s needed.
How Variable Rate Irrigation works
VRI provides precision control of all sprinklers on a center pivot irrigation system by pulsing each individual sprin-
kler on and off. This allows the application rate to be modied along the entire length of the system.
First, a map of the eld to be irrigated is uploaded to the VRI program. This can either be drawn in from aerial pho-
tographs (such as Google Maps), using soil maps, or from points that have been recorded using a handheld GPS.
From the images, “management area boundaries” can be created, where specied zones needing less water can
be marked.
Next, the amount of water to be applied to each area must be dened. The VRI software allows the operator to
establish this application amount and program it into the system for each established “irrigation zone”. Once the
design is completed, the operator must upload the VRI program to the controller at the center pivot. (USB “Thumb
Drives” are the typical method of le transfer.)
Each sprinkler has a latching solenoid valve that is pulsed on or off by a controlling node. Each node controls four
sprinklers with individual control of each valve.

Installing Nodes, Looms and GPS Units
The nodes and cable looms have been cut to length, making it imperative that they are installed in the correct
order. Refer to the sprinkler chart for the node location and cable length. All node boxes should be mounted to the
same side of the irrigation span pipes so there is less interference with the wireless communications.
The correct node order is:
Pivot Point ► Node 1 ► Node 2 ► Node 3 ► etc.
The valve order is:
Pivot Point ► 1A ► 1B ► 1C► 1D► 2A► 2B► 2C► 2D► etc.
Note: The node enclosures are mounted on the same outlet as Valve B for each set of valves.
The nodes are set up to be connected via power cable in a “daisy chain” fashion. The power line from node 1 con-
nected to node 2; another power line connects node 2 to node 3 and so on, until reaching the 24V power supply at
the center of the system.

P/N 1600043 Rev M (ECN 34095) 4 VRI Installation Manual
It’s important when installing the cables to keep them clear of any sharp edges or moving components so as not to
damage the cables. Cables should be tied down tightly at 4 foot (1.2 meters), or less, intervals. Any excess cabling
should be bundled neatly out of the way of moving components and tied to the irrigation span cable.
Make a nal check that all cable glands are tightened properly.
Node Wiring for Most Locations (See Appendix A for Australia and New Zealand Wiring)
The node assemblies are factory wired. Only the 24VDC power connection needs to be wired at installation.
(Refer to the Standard Node Wiring Diagram below)
Note: Use shielded cable that is properly grounded for all external connections.
The red wire connects to the +24V terminal and the black wire connects to the ground terminal (GND).
Note: The black wire should never be connected to the irrigation system ground.
The valve plugs have been pre-wired and only need to be plugged onto the correct valve and to the correct posi-
tion on the Node board. Node boards installed prior to March 2015 (P/N’s 1500000, 1605633 and 1605847) must
be replaced with PCB Node Kit 1609494 (shown below.)
CAUTION: Do not reverse the polarity of the 24VDC supply.

Tornado Board
GPS Antenna Cable
GPS Installation
The end node (at the farthest end of the system) will have a Global Positioning System (GPS) receiver and a GPS
interface board (Tornado board) that must be plugged into the programming port on the Printed Circuit Board
(PCB). The GPS antenna plugs into the Tornado board as shown below.
It is important that all power and valve wires be kept low and as far away from the antenna wiring as much as pos-
sible to prevent interference with the antenna.
Excess GPS antenna cable must not be left inside the node box. Tie excess antenna cable to the node panel sup-
port bracket.
Each node circuit board has a set of DIP switches. Switches 1 through 4 set the radio communication channel.
Every set of DIP switches in a single system must be set the same. Other nearby pivot systems equipped with VRI
control should be set to a different channel to eliminate any cross-talk between the two pivots.
Flip the DIP switch down for deactivation of a channel and ip the switch up to activate the channel.
The DIP switch marked ”GPS” is for enabling nodes with GPS connected. Enable GPS by activating the GPS DIP
switch only on the node with GPS. Make sure all other nodes in the system have the GPS DIP switch deactivated.
DIP switches are set at the factory but must be veried during installation.
Before closing the door on the node panel box, ensure:
• The circuit board is securely fastened to the standoffs.
• Use cable ties to fasten all wires close to the bottom of the node enclosure to prevent electrical interference
with the node antenna and antenna wiring.
