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.

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

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).

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.

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.
