ELECTRICAL SAFETY STATEMENT
Installation of the Valley Electric Irrigation Machine - European Union Only
Valmont Industries Inc. does not install a differential (ground fault) circuit breaker in the control panel of the
Valley electric irrigation machine because the standards of protection vary according to country of destination.
The distributor must provide and install a differential (ground fault) circuit breaker that meets the standards of
the country where the Valley irrigation machine is installed.
In the European Union, differential circuit breaker protection is fixed at a maximum of 24 volts.
Good grounding of the Valley irrigation machine is required.
• If resistance to ground is lower than 80 ohms, a differential (ground fault) circuit breaker of 300 mA will meet
requirements.
• If resistance to ground is between 80 and 800 ohms, a differential (ground fault) circuit breaker of 30 mA will
meet requirements.
The power supply installation and inspection of equipment protection components or systems are the responsibility of the installer. Valmont Industries, Inc. is not responsible for the failure of equipment protection components or systems not of their manufacture.
Valley pivot irrigation machines receiving power from a generator must have a cable connected from the irrigation machine structure to a ground rod and another cable from the irrigation machine structure to the ground
terminal on generator in order for the differential (ground fault) circuit breaker to work.
The linear irrigation machines equipped with a generator are not equipped with a ground rod but must have a
cable connected from the linear irrigation machine structure to the ground terminal of the generator in order for
the differential (ground fault) circuit breaker to work.
• The resistance between the irrigation machine and the generator must be substantially below 80 ohms.

SAFETY
Use of Personal Protective Equipment
• People working in areas where there are potential electrical hazards must use, personal protective equipment
that is appropriate for the specific parts of the body to be protected and for the work to be performed. Refer to
U.S. Occupational Safety & Health Administration (OSHA) Regulations (Standards - 29 CFR) Safeguards for
personnel protection. - 1910.335, or applicable national, state or local regulations, for additional information.
• Personal protective equipment must be maintained in a safe, reliable condition and periodically inspected or
tested.
• Protective shields, protective barriers, or insulating materials must be used to protect each person from
shock, burns, or other electrically-related injuries while that person is working near exposed energized parts
which might be accidentally contacted or where dangerous electric heating or arcing might occur. When normally enclosed live parts are exposed for maintenance or repair, they must be guarded to protect unqualified
persons from contact with the live parts.
• Safety signs and tags. Safety signs, safety symbols, or accident prevention tags must be used where necessary to warn people about electrical hazards which may endanger them.
Conductive Materials and Equipment
Materials and equipment that can conduct electricity must be handled in a way that will prevent them from
contacting energized power lines, exposed conductors or circuit parts.
• When handling long conductive objects (such as but not limited to truss rods, pipes, angles and ladders) in
areas with energized power lines, exposed conductors or circuit parts, work practices (such as the use of
insulation, guarding, and material handling techniques) must be used to minimize the hazard.
• Portable ladders must have non-conductive side rails.
• Do not wear conductive articles of jewelry and clothing (such as but not limited to watch bands, bracelets,
rings, key chains, necklaces, metalized aprons, cloth with conductive thread, or metal headgear) that could
come in contact with energized power lines, exposed conductors or circuit parts.
Fall Protection
Identify potential fall hazards and determine if fall protection equipment is appropriate for the task, before beginning the work. Pay attention to hazards associated with routine and non-routine tasks. Inspect fall protection
equipment (harnesses, lanyards) and devices (guardrails, tie-off points) before each use. Use fall protection
equipment if required for the job. Be sure the fall protection equipment is right for the task, fits properly, and is in
good condition. Refer to U.S. Occupational Safety & Health Administration (OSHA) Regulations Standards - 29
CFR 1926.500, 1926.501 and 1926.502, or applicable national, state or local regulations for more information.
• When using scaffolds, make sure there is proper access, full planking, stable footing, and guard railing.
• When using a boom lift, keep feet firmly on the platform of a boom lift, use fall protection equipment tied-off
at all times to the guardrail or tie-off point.
• When using a ladder, make sure the ladder is non-conductive and the correct size for the task. Read the
ladder user instructions and be sure the ladder is in good condition. Make sure ladder is set on stable footing
and at the correct angle.

Irrigation Equipment near Airports and Crop Dusting Aircraft
• If any part of the irrigation machine comes within 3200 ft (975 m) of an airport runway, especially the approach (ends) of the runway, additional warning markers may be required. In the United States, CFR Title 14,
Chapter I, Subchapter E, Part 77 – Safe, Efficient Use, and Preservation of the Navigable Airspace describes
when marking is needed.
This document is available at: www.ecfr.gov
• Marking requirements vary depending on the location of the irrigation equipment relative to the runway, the
type of airport (Civil, Military, or Heliport) and other factors. Contact the local airport authority for guidance
and specific recommendations. In the United States, guidelines for marking structures near airports are
published by the Federal Aviation Administration in Advisory Circular AC 70/7460-1L – Obstruction Marking
and Lighting.
Available here: www.faa.gov/regulations_policies/advisory_circulars
• For irrigation machines near private or unregulated airfields, including farm-based airstrips, Valley strongly
recommends complying with the same standards and requirements as Civil airports as shown in Part 77.
• Regulations vary by country, contact your local aviation authority for guidance.
Overhang cables, including overhang back cables are a particular danger. In locations where low-flying aircraft are likely, such as within 1,500 ft (457 m) of an end of an airport runway, or where crop dusting aircraft
are common, Valley recommends adding obstruction markers to overhang cables to improve their visibility.
For large overhangs (36 ft / 10.97 m Heavy Duty and longer), five 12 in (300 mm) or 20 in (500 mm), aviation
orange marker balls are sufficient. One near the rabbit ears, two in the middle of the back cables and two in
the middle of the highest overhang cables. Refer to Section 3.5 in AC70/7460-1 for additional details. Aviation marker balls are available online and from a variety of aviation and airport safety equipment providers.

SAFETY
Overhead Power Lines
Assembling, towing or transporting irrigation machine components such as but not limited to the pivot point,
linear cart, span/drive unit assemblies, overhangs and/or corner assemblies underneath or near power lines is
extremely dangerous because of the risk of electrocution.
Operating equipment that elevates irrigation machine components, such as but not limited to an aerial lift or
crane, near power lines is extremely dangerous because of the risk of electrocution. Only qualified personnel
should operate this type of equipment. Before operating the equipment, qualified personnel must read the
equipment manufacturers’ operating and safety instructions.
Refer to U.S. Occupational Safety & Health Administration (OSHA) Regulations (Standards - 29 CFR) Cranes
and derricks. - 1926.550, or any other applicable national, state or local regulations for additional information.
• Always presume that any overhead power line is an energized line unless and until the person(s) owning
the line and/or the electrical utility authorities indicate that it is not an energized line and it has been visibly
grounded.
• Before operating any equipment near any power line make sure the line has been de-energized and visibly
grounded at the point of work.
• Electrocution can occur without touching an electrical power line. Electricity, depending on the magnitude,
can jump or become induced into equipment or conductive materials that come in close proximity to, but do
not touch a power line. High wind, lightning, wet ground and other environmental conditions will increase the
possibility of electrocution and require additional consideration.
• Transmitter towers can induce the equipment or materials being handled with an electrical charge. Before
working or operating equipment near transmitter towers, make sure the transmitter is de-energized.
• Select the location where the span/drive unit will be assembled to ensure that neither the irrigation machine,
or the equipment used during the assembly process, will violate the minimum clearance guidelines.
• Never operate equipment or allow the load, ropes or tag lines within 10 ft (3.05 m) of any power line rated 50
kV or lower whether it is energized or not. For lines rated over 50 kV, the minimum clearance shall be 10 ft
(3.05 m) plus 0.4 in (1.1 cm) for each kV over 50 kVs.
• Never assemble, tow, transport or allow irrigation machine components underneath or within 10 ft (3.05 m)
of any power line rated 50 kV or lower whether it is energized or not. For lines rated over 50 kV, the minimum
clearance shall be 10 ft (3.05 m) plus 0.4 in (1.1 cm) for each kV over 50 kVs. Overhang support angles,
cables and spinner drive components regularly extend 10 ft to 12 ft (3.1 m to 3.7 m) above the irrigation
pipeline (span).
• Use barricades to identify areas where interference with overhead power lines could occur. Keep the assembly, towing or transporting of irrigation machine components and the operation of equipment including load,
ropes or tag lines away from any power line, in the distances described above, whether the line is energized
or not.
• Always designate a person to observe clearance between the power line and all equipment being operated
or moved in order to give timely warning for all operations to STOP if the minimum clearance is violated.

SAFETY
Minimal Lockout / Tagout Procedure
The following procedure establishes the minimum requirements for the lockout of energy isolating devices
whenever maintenance or servicing is done on machines or equipment. It is used to ensure that the machine
or equipment is stopped, isolated from all potentially hazardous energy sources and locked out before personnel perform any servicing or maintenance where the unexpectedly energized or start-up of the machine or
equipment or release of stored energy could cause injury. All personnel, upon observing a machine or piece of
equipment which is locked out to perform servicing or maintenance shall not attempt to start, energize, or use
that machine or equipment.
When the energy isolating devices are not lockable, tagout should be used and affected personnel must wear
full personal protection.
Refer to U.S. Occupational Safety & Health Administration (OSHA) Regulations (Standards - 29 CFR) Typical
minimal lockout procedures - 1910.147 App A, or applicable national, state or local regulations, for additional
information.
Sequence of Lockout
1. Notify all affected personnel that servicing or maintenance is required on a machine or equipment and that
the machine or equipment must be shut down and locked out to perform the servicing or maintenance.
2. The authorized personnel shall identify the type and magnitude of the energy that the machine or equipment utilizes, shall understand the hazards of the energy, and shall know the methods to control the energy.
3. If the machine or equipment is operating, shut it down by the normal stopping procedure (depress the stop
button, open switch, close valve, etc.).
4. De-activate the energy isolating device(s) so that the machine or equipment is isolated from the energy
source(s).
5. Lock out the energy isolating device(s) with assigned individual lock(s).
6. Stored or residual energy (such as that in capacitors, springs, elevated machine members, rotating flywheels, hydraulic systems, and air, gas, steam, or water pressure, etc.) must be dissipated or restrained by
methods such as grounding, repositioning, blocking, bleeding down, etc.
7. Ensure that the equipment is disconnected from the energy source(s) by first checking that no personnel
are exposed, then verify the isolation of the equipment by operating the push button or other normal operating control(s) or by testing to make certain the equipment will not operate.
!
CAUTION
• RETURN OPERATING CONTROL(S) TO NEUTRAL OR “OFF” POSITION AFTER VERIFYING THE
ISOLATION OF THE EQUIPMENT.
8. The machine or equipment is now locked out.
!
DANGER
• WHEN PERSONNEL WILL BE EXPOSED TO CIRCUIT ELEMENTS AND ELECTRICAL PARTS, A
QUALIFIED PERSON MUST USE TEST EQUIPMENT TO VERIFY THAT THE CIRCUIT ELEMENTS
AND EQUIPMENT PARTS OF THE EQUIPMENT ARE DE-ENERGIZED.
Restoring Equipment to Service
When the servicing or maintenance is completed and the machine or equipment is ready to return to normal
operating condition, the following steps shall be taken:
1. Check the machine or equipment and the immediate area around the machine to ensure that non-essential
items are removed and that the machine or equipment components are operationally intact.
2. Check the work area to ensure that all personnel are safely positioned or removed from the area.
3. Verify that the controls are in neutral.
4. Remove the lockout devices and re-energize the machine or equipment.
5. Notify affected personnel that the servicing or maintenance is completed and the machine or equipment is
ready to be used.

SAFETY
Operate Safely
Valley Irrigation machines are designed with safety in mind. However, if this machine is operated incorrectly, it
may pose a safety threat to the operator. A good safety program is much like a chain, it is only as strong as its
weakest link. The manufacturer, dealer, and operator must maintain and improve all safety programs. Following
is a list of safety operating tips which you and all other persons servicing or operating the machine must read
and understand.
!
CAUTION
• DO NOT OPERATE THIS MACHINE WITHOUT
FIRST READING THE OWNER’S MANUALS
FOR THE MACHINE.
• READ ALL SAFETY MESSAGES IN THIS
MANUAL AND SAFETY SIGNS ON THE MACHINE.
• DO NOT LET ANYONE OPERATE THIS MACHINE WITHOUT PROPER INSTRUCTIONS.
• UNAUTHORIZED MODIFICATIONS MAY IMPAIR THE FUNCTION AND/OR SAFETY OF
THE MACHINE.
• IF YOU DO NOT UNDERSTAND ANY PART
OF THIS MANUAL, CONTACT YOUR VALLEY
DEALER.
EMPLOYEE INSTRUCTION ON SAFETY
It is very important to instruct your employees on the
safe use of this equipment at the time of their initial
assignment to operate it. DO NOT let anyone operate this equipment without proper instructions.
Safety training should be presented annually and
the service manager should ensure employees fully
understand the safety messages and what to do in
case of emergencies.
EMERGENCY STOPPING
The machine can be stopped at any time at any tower
by turning the disconnect switch, located underneath
the tower box, to the OFF position. See Figure 14-1.
!
WARNING
PROPER GROUNDING
DO NOT attempt to start the machine until the electrical service is properly installed and grounded by a
qualified electrician as per the electrical standards.
If the power supplied to the machine is not grounded
properly, severe injury or death can result should an
electrical malfunction occur.
It is your responsibility to ensure that your power
supplier and/or electrical contractor has grounded
the irrigation machine as required by the National
Electrical Code and by applicable local electrical
codes. If a machine is properly grounded and fuse
sizing is correct, there is extremely low probability of
an individual being injured by electrical shock.
NOTE
• All 480 VAC, 60 Hz. (380 VAC, 50 Hz.) power
supply services MUST be a 4 conductor service. Three 480 VAC (380 VAC) power lines
and one ground conductor which is as large
as the power carrying conductors for that
service.

OVERVIEW
Rainger Linear
There are two different types of Rainger Linear four wheel cart: Standard or Swing Around. The Standard
Rainger Linear can be a Center Feed or End Feed system. The Swing Around Rainger Linear has a swivel on
the cart and can only be an End Feed system. A closed delivery hose drag or open delivery ditch feed may be
used with either type of cart. The closed delivery hose drag cart may have a side or center inlet. Each Standard
Rainger Linear and Swing Around Rainger Linear machine has a free standing span located approximately
in the center of the system. The placement of the tower boxes varies depending on the type of machine and
guidance system.
Standard Cart - Center Feed System
Closed Delivery Hose Drag / Open Delivery Ditch Feed
Typically the four wheel cart is located next to the water supply pipeline or ditch and can be a attached to any
span. The free-standing span is located in the middle of the machine. Directly over the cart, there is a center
feed tower box. The central pulse tower box is located on the end of free standing span that is furthest away
from the cart. The center feed system has two end towers with each end tower having an end tower box. All
other tower boxes are linear intermediate tower boxes. See Figure 21-1.

OVERVIEW
Standard Cart - End Feed System
Closed Delivery Hose Drag / Open Delivery Ditch Feed
If the water supply pipeline or ditch is located at the edge of the field, the four wheel cart will be the end tower
next to the water supply pipeline or ditch. The hose drag linear cart may have a side inlet or center inlet.
The central pulse tower box is always on the opposite end of the system from the four wheel cart. Its location
varies depending on the total number of spans or the type of guidance system.
• When there are 5 spans or less the central pulse tower box is located on the first tower from the end.
• When there are 6 spans or more the central pulse tower box is located on the second tower from the end.
• With a Below Ground Guidance System the central pulse tower box is located on the end of free standing
span that is furthest away from the cart.
Linear intermediate tower boxes are installed on both ends of the free-standing span.
There is no tower box on the span directly over the control panel or cart and only one end tower box located on
the other end of the system. All other tower boxes are intermediate tower boxes. See Figure 22-1.

Water is transported across the field through a pipeline. The pipeline is made up of a series of spans
which are connected together. Each span consists of
truss assemblies and truss rods to support the span
a tower box that acts as a junction box for the span
cable and motor lead, and a drive tower which moves
the pipeline across the field. See Figure 25-1.
Drive Towers
Power to the electric motor on the center drive gearbox is supplied by the tower box. The center drive
gearbox drives the wheel gearboxes. See Figure
25-2.

Hitch
The spans are attached to each other with a ball hitch
and cup assembly which gives lateral, rotational, and
vertical flexibility between the spans. See Figure
25-3.
The span pipeline is connected together with a flexible hose and held in place with band clamps. See
Figure 25-3.
Overhang
Typically an overhang is attached to the end of the
last span pipe and used for irrigation beyond the
span/drive unit. Support ears and cables provide
support for the overhang. See Figure 25-4.
End Gun
Typically a booster pump is installed and an end gun
is attached at the end of the overhang and used to
increase the area irrigated beyond the end of the
machine. See Figure 25-5.
The end gun is set to cover a specified area. This
area is determined by the forward and backward
angles, which are referred to as the end gun arc settings. See Figure 25-6.

OVERVIEW
Water Application
A sprinkler chart provides the operator with information about water application depths and pass times at
different percent timer settings.
Water is applied to the field through the sprinklers.
Sprinklers can be mounted on top of the pipeline
or on drop tubes that hang below the pipeline. See
Figure 26-1.

Side Load Safety Box
The side load safety box will shut down the machine
if the span gets out of alignment with the linear cart.
The side load safety box location varies depending
on the type of Rainger Linear cart.
• If Rainger linear center or end feed cart, the side
load safety box is located on the first span pipe.
See Figure 26-2.
• If Rainger linear swing around cart, the side load
safety box is located on the Rainger Linear cart.
See Figure 26-3.
See Maintenance section for adjustment procedure.
Span Cable
A cable with color coded wires enters and leaves
each tower box. The cable runs the entire length of
the machine and is referred to as span cable. See
Figure 26-4.
The span cable can carry multiple voltages including high voltage depending on control panel and the
country of use.
Intermediate Tower Boxes
The intermediate tower control boxes provide power
to the center drive gear motors depending on the
tower box position in relationship to the next tower in
the system. See Figure 26-4.

The central pulse tower box provides power to the
center drive gear motor depending on its position in
relationship to the last tower and the machine’s angle
to the guidance system.
The basic components include safety microswitch,
run microswitch, motor contactor, terminal block,
disconnect, overwatering timer, and pulse timer. See
Figure 27-1.
The overwatering timer is a safety device used to shut
the system off if one of the end towers fail to move
during the overwatering timer cycle. See Figure 27-2.
The overwatering timer cycle is adjustable from 0 to
60 minutes.
Each time the central pulse tower moves, the overwatering timer is reset and another timer cycle begins.
The pulse timer is part of the linear steering system.
See Figure 27-3.
During operation, the linear machine moves at a 90°
angle to the guidance system. If this angle changes,
the linear irrigation machine must steer itself back to
the correct operating position.
When the linear machine steers, the pulse timer
restricts the run time of the leading end tower to a
percentage of the run time of the tower where the
pulse timer is located. This allows the trailing end
tower to catch up, while minimizing radical steering
and possible structural damage.
The pulse timer dial is factory set to 20 percent and
sealed in position.

OVERVIEW
Safety Circuit
The safety circuit is a 120 volt AC control circuit that
starts in the control panel and runs the entire length
of the machine. See Figure 28-1.
Each drive tower box contains a safety microswitch.
The safety microswitches must be closed to complete the safety circuit.
When the machine is in alignment, the safety
microswitches are closed. If the machine ever becomes too far out of alignment, a safety microswitch
opens, breaking the safety circuit. This stops the
machine to prevent structural damage.
Alignment
There are 2 types of span alignment for linear machines, modified or floating alignment. The type of
alignment used depends on the number of spans.
• Linear machines with five spans or less can use
modified or floating alignment. See Figures 28-2
and 28-3.
• Linear machines with six spans or more must use
floating alignment.
The end tower is the controlling tower. As the end
tower moves, all of the other towers move to maintain
straight alignment.
When the end towers move, they create an angular
deflection with the next tower, this closes the run
microswitches and causes the next tower to move.
This cycle repeats itself throughout the length of the
entire machine.
The result of these cycles is that any tower can be
moving at any time, depending on its relationship
with the next outer span.
See Maintenance section for adjustment procedure.

There are 3 types of guidance for Rainger Linear machines, above ground cable, furrow or below ground
guidance. Either type of guidance can be used.
Above Ground Guidance (Option)
The above ground cable guidance system consists of
an above ground cable supported by posts running
parallel with the ditch or the water supply pipeline.
Two guidance boxes, attached to the linear cart
straddle the cable. See Figure 29-1.
As the machine travels through the field, the control
arms straddle the cable. If the machine moves off
course, movement of the leading control arms will
call for a steer in the appropriate direction.
OVERVIEW
Guidance

Furrow Guidance (Option)
The furrow guidance system consists of two furrow
guidance boxes, arms, and skids mounted on the
linear cart. See Figure 29-2.
The skids follow a “V” shaped furrow, 4 in to 6 in
(101.6 mm - 152.4 mm) deep, running the length
of the field. See Maintenance section for detailed
instructions on furrow maintenance and construction.
When the linear cart moves away from the furrow,
the guidance arm will actuate a steer switch bringing the linear cart back into the correct position. If
the steer switch should fail, a back-up safety switch
would shut the machine down.
Below Ground Guidance (Option)
The below ground guidance system consists of a
buried single loop wire running through the center of
the field, a guidance box, five antennas mounted on
the machine and an oscillator to energize the buried
wire. The buried wire emits a signal when the oscillator is ON. Make sure the oscillator is turned ON
before using the machine.
The reference antenna sits directly above the buried
wire monitoring its signal. As the forward or reverse
steering antenna moves to the left or right of the buried wire it will become in phase or out of phase with
the reference antenna and cause the system to steer
back onto the wire. See Figure 29-3.
The phase loss antennas are located on each side
of the buried wire. As long as the wire stays between
these two antennas the machine will continue to run.
If either phase loss antenna crosses over the wire,
the safety circuit will open and the machine will shut
down. See Figure 29-3.

OVERVIEW
Control Panel
The control panel allows the operator to control the
machine. The control panel is located at the linear
cart. See Figure 30-1.
Basic functions controlled by the panel include:
1. Starting/Stopping
2. Selecting forward or reverse running direction
3. Selecting machine speed (which controls the
amount of water being applied).
When the machine is started, the AC power is sent
through the span cable to the tower boxes. The
control circuit distributes the power to the drive motors through the motor contactors and the machine
moves depending on the control panel settings.
Refer to the control panel owner’s manual for detailed
information about the control panel operation.
Electric Cord Drag (Options)
Closed Delivery
The electric cord mounting with safety switch can be
mounted horizontally or vertically on the cart. See
Figure 30-2.
The electric cord is spring loaded. If the electric cord
is pulled beyond the limits of the safety switch setting,
the safety switch opens to shut down the machine.
Open Delivery
The electric cord mounting with safety switch is
mounted vertically on the cart between the cart disconnect panel, pump panel and junction box. See
Figure 30-3.
The electric cord is spring loaded. If the electric cord
is pulled beyond the limits of the safety switch setting,
the safety switch opens to shut down the machine.
