Introduction

The MTS Landmark System is designed to operate in a laboratory or light
industry environment. To get the maximum intended use of the system, it is
recommended that careful consideration be given to planning its installation.
This includes:

• Considerations of the types of testing that will be performed

• The building facilities requirements for power, cooling water, air

conditioning, ceiling height, floor loading, and so on

• Contract services, such as riggers and moving equipment, to transport the

system components within the facility

• Support personnel that might be required during installation of the system

Each test application has its own requirements in addition to the test system
requirements. Therefore, it is recommended that overall planning be considered
as early as possible. Preparation for and setup of the major system components is
your responsibility. This guide will help answer most of your questions about the
physical characteristics and requirements of your system.

Introduction

Landmark Test System Site Prep Guide

Facility Preparation

This section describes the physical, electrical, and mechanical requirements that
must be considered before installing the Landmark System. Read the following
subsections thoroughly to identify installation considerations that apply to your
facility.

Preparing to Receive the System

Before you call MTS for installation, there are several customer responsibilities
before and after receiving your test system. If you have any questions or concerns
about any of the following, please contact MTS.

Before your system

arrives

Prior to receiving the system, ensure suitable rigging equipment is available for
lifting and transporting the system components. The major components of the
system consist of the hydraulic power unit (HPU), the load unit and the
electronics console. See System Component Specifications for more information.

Before your equipment arrives, ensure your facility is ready for installation.
Things that need to be in place include:

• Proper foundation where the load frame will be positioned.

• HPU cooling water available.

• Electrical power available for the HPU and test controller.

• Network set up and internet connections available.

• If you are supplying the computer workstation, make sure:

– it is set up with an appropriate Windows operating system,

– it has general business applications installed,

– it is connected to your network and has internet access.

After your system arrives After your system arrives, it is your responsibility to have the system uncrated

and moved to its final position before calling MTS for installation.

Be sure to have personnel available for training when the MTS Service Engineer
comes for installation. You should also have your network IT people available in
case there are internet or network issues that need to be resolved; for example IP
address assignments for the computer workstation.

Space Requirements

Consideration must be given to planning the space requirements around the
equipment for loading specimens and for the proper maintenance of the
equipment. Also, during installation of the equipment, additional space (floor
space and ceiling height) might be required to facilitate moving the various
system components into place. Shown below, is a typical configuration for a
system laboratory plan allowing for relative placement of the test machine
controls and mechanical components for convenient use. This is only a
suggestion of how a Landmark System could be installed. Your requirements
should be considered and planned accordingly.

Consideration should also be given to handling specimens, test data, and storage
of fixturing and associated tools necessary for use and service of the system. If
hazardous test specimens (such as those pressurized internally with gas or
fragmentizing materials) are used in the test, protective enclosures and special
laboratory layouts are advised.

Foundation Requirements

Foundations for load frame systems will generally be reinforced concrete cast in
place in the ground. These are sometimes called fixed reaction masses, seismic
bases, etc. Still other methods of supporting a load frame can involve a strong
floor or other test floor already at the customer site.

Facility Preparation

8

Landmark Test System Site Prep Guide

The dynamic response characteristics of the foundation should be limited to low
levels so that the accuracy and performance of the MTS equipment mounted on
the foundation will not be affected. An improper foundation mass can affect
equipment performance. This is particularly true in strain-controlled, low­frequency or strain-controlled monotonic testing.

If you have any questions or concerns about the suitably of your foundation,
contact MTS.

Floor Loading Considerations

Once the final layout for your system laboratory has been developed, the
dimensional and weight information for the various system components should
be supplied to the building facility personnel to ensure that proper building
loading and vibration considerations have been evaluated.

The load unit comes equipped with vibration isolators that are designed to
distribute the load into the floor and to provide isolation from excitation caused
by movement of the actuator rod. These vibration isolators will be found in a
carton which will accompany the load unit. This carton also contains other
accessories basic to load unit operation. If high cycle fatigue testing is to be
performed, place the load unit such that vibrations do not excite undesirable
resonances or cause excessive loads in the building structure.

Hydraulic power units rest on a special base flat on the floor. Resting flat on the
floor provides maximum loading distribution. See “Model 505.07/.11

Specifications” on page 18 and “Model 505.20/.30 Specifications” on page 20.

A review of the final installation plan by building personnel is recommended to
check static and dynamic floor loading.

Mechanical Shock/Vibration

Where impact testing is performed or in higher speed fatigue testing, cyclic loads
and simple shock pulses can be introduced into the laboratory floor. Adequate
isolation of the load unit is often possible with the supplied vibration isolators.
However, in some cases, an optional air bag isolation device might be required.
Contact your MTS representative for additional details.

Electrical Power Distribution

The input line voltage to the Landmark System must be adequately rated for the
loads under which the system operates. Size the power system with adequate
reserve for future equipment additions and installation expansion. Both the HPU
and the console controls must be considered in the distribution system, with
emphasis on providing “interference free” electrical power to the controls. Plan
routing of power cables away from instrumentation cables (for example,
transducer cables). Avoid long parallel runs of power cables in close proximity to
instrumentation cables. Power cables should be separated from instrumentation
cables by 1 to 3 ft (0.3 to 1 m).

Landmark Test System Site Prep Guide Facility Preparation

9

Grounding Requirements

Each system has its own internal grounding system, which is common grounded
through the green or green/yellow wire in the power cable and must also return to
earth ground, through the conduit of the electrical distribution system. Note that
the green or green/yellow wire must not be a current-carrying conductor or a
neutral conductor. A ground strap is provided to tie the load unit assembly
directly to the console cabinet.

Where electrical power is of poor quality (noise spikes, poorly regulated, and so
forth) or the ground system in the facility contains electrical noise, attach a 4
AWG wire directly to a good earth ground point such as a 6 ft (2 m) copper
grounding rod driven at least 6 ft (2 m) into the ground. Grounding must conform
to local electrical codes.

Console Control Power

Electrical power to the system controls should be filtered from outside RF
interference and line regulated to provide 105-130 Vac or 200-240 Vac, 50-60
Hz. An isolated power source or uninterruptible power supply is recommended if
it is desirable to maintain control power for longer than the delay built into the
control electronics (approximately one second). Make sure that the service to the
Landmark System is not on a line that can be accidentally shut off. Power
supplied to the Landmark System should be on an isolated circuit, or on its own
transformer from the main power box.

Radiated Emissions

Operation of the Landmark System can be affected by sources of electromagnetic
interference (EMI) that are near the system controls, computer, instrumentation
cables, and related peripheral equipment. Common sources of EMI are electric
motors, broadcast systems, high-voltage power lines, power tools, mobile
communications, radar, vehicle ignition systems, static electricity, induction
heaters, fluorescent lights, and lightning. The effects of EMI are unpredictable,
additional grounding and shielding might be necessary. Techniques such as using
screen cages or other metal surfaces around the system, along with good
grounding practices and proper storage of magnetic memory medium, are
recommended.

Fixture and Specimen Handling Considerations

Movement of specimens in and out of the test system must be considered early in
the planning of the site layout. With smaller specimens, the use of a rolling work
cart with lift-off storage drawers is often recommended to facilitate the handling
of specimens and to minimize the chance of damage to the specimens prior to
and after the test. As specimen size and fixturing increase beyond the typical
lifting capacity of laboratory personnel, use of an overhead crane, lifting straps,
or a forklift might be necessary to handle specimens or fixtures.

If the load unit does not have hydraulic lifts and locks, an overhead crane or other
suitable lifting device can be used to change the crosshead position to
accommodate specimen or fixture length.

Landmark Test System Site Prep Guide

Acoustics

Temperature

Heat Dissipation

Some types of fatigue testing can produce noise which is undesirable or
potentially damaging to hearing. Acoustical treatment of walls and ceiling might
be necessary to prevent harm to personnel. If disk drives are included in the
system, acoustical materials should not be of the type that generates or harbors
dust. The Series 505 SilentFlo™ Hydraulic Power Units are designed for
relatively quiet operation; no special acoustical considerations are necessary.

However, the use of hearing protection is recommended for personnel involved
in long-term testing in a noisy testing environment.

The operating temperature range of the electronics console is 64°F to 86°F (18°C
to 30°C). This includes most temperature sensitive equipment, such as disk
drives which are dependent on cooler air to maintain proper height of read/write
heads. Although the load cell or force transducer is temperature compensated, it
is recommended that room air heating and cooling outlets be directed so that they
uniformly distribute air throughout the room. This is primarily due to the
potential changes in specimen characteristics or test data associated with changes
in temperature.

Altitude

For comfortable working conditions and proper operation of the equipment, the
heat dissipation of the hydraulic power equipment, electronics console, and other
equipment must be considered in providing adequate heating or air conditioning
to the laboratory area.

The HPU is normally located in a room separate from the test system to reduce
heat loading and acoustical noise near operating personnel. For specific
requirements, see “Model 505.07/.11 Specifications” on page 18 and “Model

505.20/.30 Specifications” on page 20. A 40°C (104°F) maximum environment

is recommended for the HPU. Care must be taken to ensure that it is not placed in
a location subject to freezing when water cooling is used. Reservoir heaters and
oil-to-air coolers are available; consult your MTS representative.

Heat dissipation for the console and other electronic units can be estimated by
summing the losses going to heat in the room {approximately 6000 Btu/hr (1500
kcal/hr) for a single 15 amp power panel or 8000 Btu/hr (2000 kcal/hr) for a
single 20 amp power panel} and the gains from personnel and other heat inputs
such as furnaces. To this figure, you should add 20% additional heat gain for
future changes in test requirements.

Systems operated at high altitudes can have heat dissipation problems because of
the lower density of the air. This type of problem might require the use of an air
conditioned environment or cooling fans to reduce the heat load. The specified
equipment environment should be reduced by 0.55°F per 1000 feet (1.0°C per
1000 meters) above sea level. Most equipment can be operated at altitudes up to
8000 feet (2400 meters). Refer to equipment product specifications for any
altitude restrictions.

Landmark Test System Site Prep Guide Facility Preparation

11

Relative Humidity

The recommended relative humidity for the test room is within the range of 40%
to 65% (non-condensing). The risk of static discharge, which easily damages
logic components and causes loss of data in memory devices, is increased by low
humidity. Excessive humidity can result in electrical leakage currents or
component failure.

Leveling System Components

Shims can be used under the load unit feet or isolation pads to level the load unit
on an uneven floor.

Console type cabinets have leveling feet that allow the cabinet to be leveled as
necessary. No particular level alignment of the console is necessary other than to
ensure the footing is solid and the console cannot be rocked. Disk storage drives
do, however, require proper leveling of the equipment to minimize wear on the
read/write heads and fan bearings.

HPU Considerations

HPU Considerations

HPU Cooling Water Requirements

The hydraulic power units (HPUs) water connections are supplied with hose
nipples for the recommended type of hoses. The common type of recommended
hose is Uniroyal P-340 or equivalent hose rated for 150 psi (1.03 MPa) operation.
Shutoff valves should be included in the facility supply and drain lines should be
included to allow for unit maintenance. If the cooling water contains
contaminants (such as sediment) water filtration might be necessary to prevent
clogging of the heat exchanger tubes. See “Hydraulic Power Unit Specifications”
on page 17 to find water pressure, hose size requirements, and water cooling
requirements for the HPU.

HPU Electrical Requirements

The electrical interface to the HPU occurs at the HPU starter box located on the
unit. Power cable access is provided into the box with cables coming from a
customer-supplied, fused electrical service disconnect. This disconnect must be
provided to safely remove all power to the HPU for maintenance work. Hookup
must conform to local electrical codes and regulations, see “Model 505.07/.11

Specifications” on page 18 and “Model 505.20/.30 Specifications” on page 20.

Water Quality

HPUs are equipped with water-to-oil heat exchangers that are designed to
remove 100% of the HPUs heat load. Water-to-oil heat exchangers, also referred
to as oil coolers, use heat transfer to cool the hot oil in the HPU by passing it over
tubes filled with cooling water.

Water chemistry is critical for a successful heat exchange system. Generally
speaking, municipal drinking water that is available in developed countries is
perfectly acceptable for copper tube heat exchangers. This water is non-polluted,
bacteriologically safe and has a neutral pH.

Cooling towers and natural water sources such as wells, rivers or ponds must be
free of pollutants and treated to limit contaminants to the same levels as
municipal drinking water.

Additional Considerations

28

Landmark Test System Site Prep Guide

HPU Considerations

Softened or distilled water might not be good to use as a cooling liquid because
although most of the minerals have been removed there is a higher than desirable
level of carbon dioxide and oxygen present in the water. High levels of carbon
dioxide and oxygen will act to decrease the protective layer of minerals that form
on the surface of the tube, and increase the formation of copper oxide.

Some contaminants in the cooling water supply can operate together to create
corrosion rates a hundred times higher than would be seen by either contaminant
acting alone. Cooling towers, unless regularly treated and controlled, are the
systems that have had the most problems with corroded heat exchangers.

Local industrial water treatment specialists can provide information on your
water conditions and solutions to contaminant problems.

Load Unit Considerations

Load Unit Considerations

The load unit is typically shipped in a horizontal position on a pallet or in a crate.
Lifting and moving instructions that describe proper handling methods are placed
in a protective envelope and shipped with the load unit. These instructions
include recommended methods to remove the unit from the pallet, raise the unit
erect, and move it into position. Read all provided instructions carefully to
understand how to handle the weight of the components. It is recommended that
personnel experienced in the practice of rigging for construction and industrial
operations be employed. The proper use of lifting slings where the center of
gravity is elevated above the floor is essential to the safety of personnel and
equipment.

After the load unit is moved into position, install the vibration isolation pads to
ensure proper vibration isolation between the load unit and floor.

The routing path of the hydraulic hoses and electrical cables should be noted with
respect to any obstructions that could cause the hose or cable to be abraded by
rubbing during machine operation. It is recommended that electrical cabling be
routed in overhead wire trays or, as a minimum, be protected on the floor with
adequate covering to prevent damage caused during fixturing, by dropping
specimens and tools, or by walking on them. Sufficient space should also be left
around the load unit for maintenance and final hook-ups.

Electronic Console Considerations

Console Handling Requirements

The electronic console is shipped with a protective covering to prevent damage to
the controls and cable connectors and to prevent dust infiltration. It is
recommended that the covering not be removed until the unit has been placed in
its final position for expected use.

Large stand-up consoles have lifting eyes as well as casters for easy movement.
When moving the console using the lifting eyes, lift it only as high as necessary.
When moving the unit using the casters, be sure the surface is smooth and level
and the leveling pads are fully screwed up into the base of the cabinet. Due to the
high center of gravity of the console, two people are required to roll the console if
the floor has obstructions or is uneven or bumpy; use one person on each side of
the console to watch for obstructions. Move the unit with the front controls away
from the direction of travel, thereby minimizing the damage that could occur if
the console tipped over. Cable exit from the console is at the rear, through a slot
below the rear door; therefore, location of the cable trays and routing should be
considered from this point. Use the same methods for protecting the electronic
cables as those used for the hydraulic hoses. Adequate clearance must be
provided for rear console access to permit cable attachment, fuse replacement, air
filter replacement, and component maintenance.

Computer Console Considerations

Computer Console Considerations

Packaging and movement of the computer console is similar to the electronic
console. Other peripheral components (such as disk drives) that are susceptible to
dust contamination should be placed away from obvious sources of
contamination, and the room should be slightly positively pressurized to prevent
migration of dust and dirt into the room.

When You Get Your System

Operation of your system can involve exposure to hazardous situations: high
voltages are present at the hydraulic power unit and the control consoles. The
control consoles control the movement of the actuator which uses high pressure
hydraulic fluid. Because of these potential hazards, your system is provided with
documentation that includes information on safety practices. Read this
information before attempting to operate your system.

If the source of cooling water is a cooling tower, the presence of contaminants
that are corrosive to metals will vary over time. Contaminants must be controlled
to the quantities listed in the following table. Ideally, the pH should be
maintained in the 6.5-8.0 range for most applications, and chlorine should be
used to limit the growth of microbiologic organisms that are generated by protein
decay. You must be careful not to use excessive amounts of chlorine: the chloride
concentration in the cooling water must be kept to less than 5 ppm.
