Installation Of The Valley Electric Irrigation Machine
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 machines are the re-
sponsibility of the installer. Valmont Industries Inc. is not responsible for the failure of equipment protection
components or machines not of their manufacture.
Valley pivot irrigation machines receiving power from a generator must have a cable connected from the irriga-
tion 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 resistance between the irrigation machine and the generator must be substantially below 80 ohms.

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 nor-
mally 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 neces-
sary to warn people about electrical hazards which may endanger them.
Conductive Materials And Equipment
Materials and equipment that may 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 begin-
ning 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.

Qualified Person
A Qualified Person is one who, by possession of a recognized degree, certificate, or professional standing, or
who by extensive knowledge, training, and experience, has successfully demonstrated his/her ability to solve or
resolve problems related to the subject matter, the work, or the project.
Only qualified persons may work on electric circuit parts or equipment that have not been de-energized.
Refer to U.S. Occupational Safety & Health Administration (OSHA) Regulations Standards - 29 CFR 1926.32(m)
and 1910.333, or applicable national, state or local regulations for additional information.
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 ap-
proach (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.

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, lightening, 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 assem-
bly, 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.

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 person-
nel 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 equip-
ment 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 fly-
wheels, 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 operat-
ing 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 nonessential
items have been removed and that the machine or equipment components are operationally intact.
2. Check the work area to ensure that all personnel have been safely positioned or removed from the area.
3. Verify that the controls are in neutral.
4. Remove the lockout devices and reenergize 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.

DO NOT operate the machine if it moves in the
direction opposite to that which was chosen.
Forward should be clockwise and reverse coun-
ter-clockwise.
!CAUTION
KEEP WATER OFF ROADWAYS
It is against the law in most states to allow water
to spray on state and county roadways. This is a
serious hazard to passing motorists.
If end guns are used, make sure you read and un-
derstand the correct procedures for setting the on
and off positions to avoid watering the roadways.
If an end gun is watering a roadway, immediately
discontinue use and adjust the shutoff setting or
call your Valley dealer to repair the end gun shut
off mechanism.
!CAUTION
PART CIRCLE OPERATION SAFETY
If the machine reverses direction at a roadway or a
physical object such as a building, tree line, power
pole etc., then you MUST provide a backup device
to stop the machine if the reversing mechanism
were to fail. See Figure 15-1.
Contact your Valley dealer for more information
concerning physical barricades for machines un-
der these circumstances.

!CAUTION
PROPER USE OF THE SAFETY OVERRIDE
Caution MUST be taken by the operator when us-
ing the safety override function as it will by-pass
or disable all of the machine’s automatic safety
shutdown circuits.
NEVER depress and hold the START/STOP
SAFETY OVERRIDE switch in the START posi-
tion for more than 3 to 5 seconds.
If the machine is not in full view by the operator,
do not use the Safety Override function.
The operator MUST inspect the entire machine
between each safety override start attempt.
Repeated safety override start attempts can
cause severe structural damage.
Call your Valley dealer if the machine fails to start.

Overview
Main Disconnect Switch
The main disconnect switch controls power to the
machine and has three positions, ON, OFF, and Test.
See Figure 20-1.
In the ON position, the control panel is on and power
is provided to the machine.
In the OFF position, the control panel is off and
power is disconnected from the machine. However,
incoming voltage to the control panel still exists on
the upper terminals of the main disconnect switch
inside the control panel.
The Test position is for use by service personnel only.
!
WARNING
•ALWAYS TURN THE MAIN DISCONNECT
SWITCH OFF, LOCK IT IN THE OFF POSITION
AND TAG IT WHEN DOING ANY MAINTE-
NANCE OR REPAIRS AND WHEN THE MA-
CHINE IS NOT IN USE.
Three Second Auto Restart
A three second auto restart function is built into the
circuitry of the control panel.
In the event of a momentary power loss or voltage
drop while the machine is running, the machine will
automatically restart if power is returned within three
seconds.
When the control panel also controls an irrigation
pump that is set to automatically start, the irrigation
pump must be protected with a pump restart delay.
!CAUTION
•TO REDUCE THE POSSIBILITY OF DAMAGE
TO AN AUTOMATICALLY CONTROLLED
ELECTRIC PUMP DUE TO A MOMENTARY
POWER LOSS OF 3 SECONDS OR LESS,
A PUMP RESTART DELAY IS REQUIRED IN
THE PUMP CIRCUIT BETWEEN THE PIVOT
CONTROL PANEL AND THE PUMP.
