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 machines are the
responsibility of the installer. Valmont Industries Inc. Is not responsible for the failure of equipment protection
components or machine 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 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 equip-
ment 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) Safe-
guards 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.

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 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.

11
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 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. Deactivate 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.

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 with-
out proper instructions.
• Unauthorized modifications may impair the
function and/or safety of the machine.
• If you do not understand any part of this manu-
al, 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.

Overview
Corner Identification
This section briefly describes the possible VFlex
Corner Sequencing component configurations for
standard (trailing) and inverted (leading) corners.
Standard (Trailing) Corner
Orientation for all figures is based on standing
at the pivot point looking towards the LRDU or
standing at the cradle looking towards the SDU.
The Standard (Trailing) corner can use either the fixed
or swivel inlet and either the mechanical sequencing
box or the angle sensor box. See Figures 18-1 and
18-2.
Inlet Option: Both the fixed inlet and swivel inlet
can be used with the standard (trailing) corner. See
Figures 18-1 and 18-2.
Sprinkler Rod T-Bar Mount: Mounted on the right
side of the cradle when standing at the LRDU looking
towards the SDU. See Figures 18-1 and 18-2.
Mechanical Sequencing Box: Used only with a
standard (trailing) corner. Sequencing box control
arm will be on the right side of the pipe at the
LRDU. An adjustable control rod is used with the
mechanical sequencing box. See Figure 18-1.
Angle Sensor Box: Box is mounted with the control
rod on the right side of the pipe at the LRDU. An
fixed control rod is used with the Angle Sensor
Box. See Figure 18-2.
Run Cycle Box: Mounted on the left side of the
cradle. See Figure 18-2.
Inverted (Leading) Corner
Orientation for all figures is based on standing
at the pivot point looking towards the LRDU or
standing at the cradle looking towards the SDU.
The Inverted (Leading) corner can use ONLY the
swivel inlet and the angle sensor box.
Inlet Option: The swivel inlet option can only be used
with the inverted (leading) corner. See Figure 18-3.
Sprinkler Rod T-Bar Mount: Mounted on the left
side of the t-bar. See Figure 18-3.
Angle Sensor Box: Mounted with control arm on the
left side of the pipe. The fixed control rod must be
used with the Angle Sensor Box. See Figure 18-3.
Run Cycle Box: Mounted on the right side of the
cradle. See Figure 18-3.

Overview
Time
Displays the current time according to the clock in the
VCS computer.
If the current time is 1:45:00 P.M., it appears on
the screen in the 24-hour format as 13:45:00
(hh:mm:ss). See Figure 19-1.
Corner Angle (CANGLE)
Displays the current corner angle (CANGLE) as
measured by the corner angle sensor, in degrees.
Error Code (Exx)
This field displays any currently active error codes.
The error code field (Exx) appears only when a
system error has occurred. If multiple errors occur
the error codes will cycle on the display once every
two seconds. Error codes E03-E13 will not appear.
See Figure 19-1.
Active error codes can be acknowledged and cleared
from the status screen by viewing them in the
Diagnostics Screen.
Speed
Displays the current measured percent timer setting
(SPEED:xxx%) from the smart tower board in the
VCS control panel. See Figure 19-1.
Main Status Menu
The VCS control panel display is used to show current status and information for programming and selecting
functions. When the control panel main disconnect is turned on and at all other times when the operator is not
programming the control panel, the control panel display shows the current machine status on the status screen.
See Figure 19-1. A short explanation of the status screen elements is given below and on the following pages.
NOTE
•This Status Screen example
illustrates the operating
conditions of a typical irri-
gation machine. The Status
screen of your machine will
show different conditions.
Date
Displays the current date according to the clock in
the VCS computer.
If the current date is August 18, 2013, it appears
on the screen as 08/18/13 (mm/dd/yy). See Figure
19-1.
Machine Angle (MANGLE)
Displays the current machine angle calculated from
the GPS position. If the machine angle is not valid,
"---" will be displayed. If GPS is not enabled, " " will
be displayed. See Figure 19-1.
Adjusted Speed
Displays the adjusted speed being sent to the Last
Regular Drive Unit (LRDU) when the pressure or
chemigate mode are selected.
SOL#
Displays active solenoids 1-9 on row 4.
TEN+
Displays active solenoids 10-16 on row 4.
