Safety

General Safety Practices

If you have system related responsibilities (that is, if you are an operator, service engineer, or maintenance person), you should study this manual carefully before you attempt to perform any test system procedure.

You should receive training on this system or a similar system to ensure a thorough knowledge of your equipment and the safety issues that are associated with its use. In addition, you should gain an understanding of system functions by studying the other manuals supplied with your test system. Contact MTS for information about the content and dates of training classes that are offered.

It is very important that you study the following safety information to ensure that your facility procedures and the system’s operating environment do not contribute to or result in a hazardous situation. Remember, you cannot eliminate all the hazards associated with this system, so you must learn and remain aware of the hazards that apply to your system at all times. Use these safety guidelines to help learn and identify hazards so that you can establish appropriate training and operating procedures and acquire appropriate safety equipment (such as gloves, goggles, and hearing protection).

Each test system operates within a unique environment which includes the following known variables:

•Facility variables (facility variables include the structure, atmosphere, and utilities)

•Unauthorized customer modifications to the equipment

•Operator experience and specialization

•Test specimens

Because of these variables (and the possibility of others), your system can operate under unforeseen circumstances that can result in an operating environment with unknown hazards.

Improper installation, operation, or maintenance of your system can result in hazardous conditions that can cause death, personal injury, or damage to the equipment or to the specimen. Common sense and a thorough knowledge of the system’s operating capabilities can help to determine an appropriate and safe approach to its operation.

Observe the prescribed safety practices before and during system operation.

It is the user’s responsibility to take the machine out of service and contact MTS Service if discrepancies in system operation are found.

Safety Practices Before Operating the System

Before you apply power to the test system, review and complete all of the safety practices that are applicable to your system. The goal, by doing this, is to improve the safety awareness of all personnel involved with the system and to maintain, through visual inspections, the integrity of specific system components.

Read all manuals

Study the contents of this manual and the other manuals provided with your system before attempting to perform any system function for the first time. Procedures that seem relatively simple or intuitively obvious can require a complete understanding of system operation to avoid unsafe or dangerous situations.

16 MTS Landmark™ Tabletop Load Units Product Information

Safety

Locate lockout/tagout points

Know where the lockout/tagout point is for each of the supply energies associated with your system. This includes the hydraulic, pneumatic, electric, and water supplies (as appropriate) for your system to ensure that the system is isolated from these energies when required.

Know facility safe procedures

Most facilities have internal procedures and rules regarding safe practices within the facility. Be aware of these safe practices and incorporate them into your daily operation of the system.

Locate Emergency Stop buttons

Know the location of all the system Emergency Stop buttons so that you can stop the system quickly in an emergency. Ensure that an Emergency Stop button is located within close proximity of the operator at all times.

Know controls

Before you operate the system for the first time, make a trial run through the operating procedures with the power off. Locate all hardware and software controls and know what their functions are and what adjustments they require. If any control function or operating adjustment is not clear, review the applicable information until you understand it thoroughly.

Have first aid available

Accidents can happen even when you are careful. Arrange your operator schedules so that a properly trained person is always close by to render first aid. In addition, ensure that local emergency contact information is posted clearly and in sight of the system operator.

Know potential crush and pinch points

Be aware of potential crush and pinch points on your system and keep personnel and equipment clear of these areas.

An important consideration for servohydraulic systems is that when power is interrupted, it is likely that stored accumulator pressure will persist for some time within the system. In addition, it is likely that as stored energy dissipates, gravity will cause portions of the system to move.

Be aware of component movement with hydraulics off

For hydraulic systems, be aware that mechanical assemblies can shift or drift due to changes within hydraulic hardware when hydraulics are turned off. This non-commanded movement is because oil can transfer between the pressure and return ports and across internal components of the hydraulic hardware. Be aware that this can happen and clear the area around the mechanical assemblies when hydraulics are turned off.

Know electrical hazards

When the system electrical power is turned on, minimize the potential for electrical shock hazards. Wear clothing and use tools that are properly insulated for electrical work. Avoid contact with exposed wiring or switch contacts.

Whenever possible, turn off electrical power when you work on or in proximity to any electrical system component. Observe the same precautions as those given for any other high-voltage machinery.

Make sure that all electrical components are adequately grounded. Grounds must remain connected and undisturbed at all times.

MTS Landmark™ Tabletop Load Units Product Information 17

Safety

Ensure Correct Cable Connection

If a system cable has been disconnected, ensure that you establish the correct cable-to-connector relationship during reconnection. Incorrect cable connections can result in improper servo loop phasing or an open servo loop condition, either of which can cause unstable or unexpected and potentially dangerous system motions. Verify the correct cable-to-connector relationship by observing the cable and connector labeling and the system wiring schematics.

Keep bystanders safely away

Keep bystanders at a safe distance from all equipment. Never allow bystanders to be in close proximity of specimens or equipment while the test is running.

Wear proper clothing

Do not wear neckties, shop aprons, loose clothing or jewelry, or long hair that could get caught in equipment and result in an injury. Remove loose clothing or jewelry and restrain long hair.

Remove flammable fluids

Remove flammable fluids from their containers or from components before you install the container or component. If desired, you can replace the flammable fluid with a non-flammable fluid to maintain the proper proportion of weight and balance.

Know compressed gas hazards

Your system may contain accumulators that require a high-pressure gas precharge (pressures that exceed 138 bar [2000 psi]). High-pressure devices are potentially dangerous because a great amount of energy is available in the event of an uncontrolled expansion or rupture.

Observe the following safety practices when you work with high-pressure air or gases:

•When you charge an accumulator, follow all the charging instructions provided in the appropriate product information manuals. When precharging accumulators, properly identify the type of gas to be used and the type of accumulator to be precharged.

•Use only dry-pumped nitrogen to precharge nitrogen-charged accumulators. (Dry-pumped nitrogen can also be labeled “oil pumped” or “dry water pumped.”) Do not use compressed air or oxygen for precharging: the temperature increase caused by rapid gas compression can result in highly explosive conditions when hydraulic fluid is in the presence of oxygen or compressed air.

•Always follow the recommended bleeding procedures before you remove or disassemble components that contain pressurized gas. When you bleed a gas or remove a fitting, hose, or component that contains a gas, remember that many gases cannot support life. Therefore, as the ratio of released gas to oxygen increases, so does the potential for suffocation.

•Wear appropriate safety devices to protect your hearing. Escaping air or gas can create a noise level that can damage your hearing.

•Ensure that all pressurized air or gas is bled out of a pneumatic or gas-charged device before you start to disassemble it. A thorough understanding of the assembly and its pressurized areas is necessary before you undertake any maintenance. Refer to the appropriate product information for the correct bleeding procedure.

It may not be obvious or intuitive which bolts or fittings are used to restrain a pressurized area. On some assemblies, you must remove a cover plate to gain access to the structural bolts. Sometimes, to protect you from a rapid release of trapped gases, a small port is exposed when you remove this cover plate.

Exposing this port ensures that the gas precharge is fully bled before disassembly. However, this is not the recommended procedure for bleeding a pneumatic or gas-charged device, because it can expose you

18 MTS Landmark™ Tabletop Load Units Product Information

Safety

to the dangers of escaping compressed gas and particulates that are expelled from the chamber or around the seals. Do not assume that cover plates and ports are installed in all the critical locations.

Consult MTS when in doubt about the safety or reliability of any system-related procedure or modification that involves devices that contain any type of compressed gas.

Check bolt ratings and torques

To ensure a reliable product, fasteners (such as bolts and tie rods) used in MTS-manufactured systems are torqued to specific requirements. If a fastener is loosened or the configuration of a component within the system is modified, refer to the system and component assembly drawings (located on the System Documentation CD) to determine the correct fastener, fastener rating, and torque. Over torquing or under torquing a fastener can create a hazardous situation due to the high forces and pressures present in MTS test systems.

On rare occasions, a fastener can fail even when it is correctly installed. Failure usually occurs during torquing, but it can occur several days later. Failure of a fastener can result in a high velocity projectile. Therefore, it is a good practice to avoid stationing personnel in line with or below assemblies that contain large or long fasteners.

Practice good housekeeping

Keep the floors in the work area clean. Industrial chemicals, such as hydraulic fluid, that are spilled on any type of floor can result in a dangerous, slippery surface. Do not leave tools, fixtures, or other items not specific to the test, lying about on the floor, system, or decking.

Protect hoses and cables

Protect electrical cables from spilled fluids and from excessive temperatures that can cause the cables to harden and eventually fail. Ensure that all cables have appropriate strain relief devices installed at the cable and near the connector plug. Do not use the connector plug as a strain relief.

Protect all system hoses and cables from sharp or abrasive objects that can cause the hose or cable to fail. Use a cable cover or cable tray where cables are in traffic locations. Never walk on hoses or cables or move heavy objects over them. Route hoses and cables away from areas that expose them to possible damage.

Provide proper hydraulic fluid filtration

For hydraulic systems equipped with a non-MTS hydraulic power unit, make sure that hydraulic fluid filtration is established to maintain fluid cleanliness standards as stated in the Hydraulic Fluid Care Manual (see the System Documentation CD). Particles present in the hydraulic fluid can cause erratic or poor system response.

Protect accumulators from moving objects

For systems equipped with accumulators, protect accumulators with supports or guards. Do not strike accumulators with moving objects. This could cause the accumulator(s) to separate from the manifold resulting in equipment damage and personal injury.

Record changes

If you change any operating procedure, write the change and the date of the change in the appropriate manual.

Provide test area guards

Use protective guards such as cages, enclosures, and special laboratory layouts when you work with hazardous test specimens (for example, brittle or fragmenting materials or materials that are internally pressurized).

MTS Landmark™ Tabletop Load Units Product Information 19

Safety

Do not exceed the Maximum Supply Pressure

For hydraulic systems and components, make sure that hydraulic supply pressure is limited to the maximum pressure defined by the system operating limits. Read and review “System Operating Limits” for the system.

Do not disable safety devices

Your system may have active or passive safety devices installed to prevent system operation if the device indicates an unsafe condition. Do not disable such devices as it may result in unexpected system motion.

Use appropriately sized fuses

Whenever you replace fuses for the system or supply, ensure that you use a fuse that is appropriately sized and correctly installed. Undersized or oversized fuses can result in cables that overheat and fuses that explode. Either instance creates a fire hazard.

Provide adequate lighting

Ensure adequate lighting to minimize the chance of operation errors, equipment damage, and personal injury.

Provide adequate ventilation

Make sure work and maintenance areas are adequately ventilated to minimize the risks associated with the collection of hazardous fumes (such as vaporized hydraulic fluid). This is of special concern in confined areas where hydraulic equipment is operating at high pressure in confined areas.

Provide means to access out-of-reach components

Make sure you can access system components that might be out of reach while standing on the floor. For example, ladders or scaffolding might be required to reach load cell connectors on tall load units.

Safety Practices While Operating the System

Wear appropriate personal protection

Wear eye protection when you work with high-pressure hydraulic fluid, high-pressure air pressure, breakable specimens, or when anything characteristic to the specimen could break apart.

Wear ear protection when you work near electric motors, pumps, or other devices that generate high noise levels. This system may create sound pressure levels that exceed 70 dbA during operation.

Wear appropriate protection (gloves, boots, suits, respirators) whenever you work with fluids, chemicals, or powders that may irritate or harm the skin, respiratory system, or eyes.

Provide test area enclosures

Use protective enclosures such as cages or shields, and special laboratory layouts when you work with hazardous test specimens (for example, brittle or fragmenting materials or materials that are internally pressurized).

Customer must evaluate risks due to ejected parts or materials from the test specimens. If the MTS Test Area Enclosure option is not selected by the customer, then for protection against ejected parts or materials from test specimens and to control access to the machinery, the Customer must provide a Test Area Enclosure to protect personnel.

20 MTS Landmark™ Tabletop Load Units Product Information

Safety

Specimen temperature changes

During cyclic testing, the specimen temperature can become hot enough to cause burns. Wear personal protection equipment (gloves) when handling specimens.

Handle chemicals safely

Whenever you use or handle chemicals (for example, hydraulic fluid, batteries, contaminated parts, electrical fluids, and maintenance waste), refer to the appropriate MSDS documentation for that material and determine the appropriate measures and equipment required to handle and use the chemical safely. Ensure that the chemical is disposed of appropriately.

Know servohydraulic system interlocks

Interlock devices should always be used and properly adjusted. Interlock devices are designed to minimize the chance of accidental damage to the test specimen or the equipment. Test all interlock devices for proper operation immediately before a test. Do not disable or bypass any interlock devices as doing so could allow hydraulic pressure to be applied regardless of the true interlock condition. The Reset/Override button is a software function that can be used to temporarily override an interlock while attempting to start the hydraulic power unit and gain control of the system.

Know system limits

Never rely on system limits such as mechanical limits or software limits to protect you or any personnel. System limits are designed to minimize the chance of accidental damage to test specimens or to equipment. Test all limits for proper operation immediately before a test. Always use these limits and adjust them properly.

Do not disturb sensors

Do not bump, wiggle, adjust, disconnect, or otherwise disturb a sensor (such as an accelerometer or extensometer) or its connecting cable when hydraulic pressure is applied.

Ensure secure cables

Ensure that all cable connections (electrical supply, control, feedback, sensor, communications, and so forth) are either locking type, or are secured, to ensure that they cannot be disconnected by a simple act. Do not change any cable connections when electrical power or hydraulic pressure is applied. If you attempt to change a cable connection while the system is in operation, an open control loop condition can result. An open control loop condition can cause a rapid, unexpected system response which can result in severe personal injury, death, or damage to equipment. Also, ensure that all cables are connected after you make any changes in the system configuration.

Stay alert

Avoid long periods of work without adequate rest. In addition, avoid long periods of repetitious, unvarying, or monotonous work because these conditions can contribute to accidents and hazardous situations. If you are too familiar with the work environment, it is easy to overlook potential hazards that exist in that environment.

Contain small leaks

Do not use your fingers or hands to stop small leaks in hydraulic or pneumatic hoses. Substantial pressures can build up, especially if the hole is small. These high pressures may cause the oil or gas to penetrate your skin, causing painful and dangerously infected wounds. Turn off the hydraulic supply and allow the hydraulic pressure to dissipate before you remove and replace the hose or any pressurized component.

Stay clear of moving equipment/avoid crush points

Stay clear of mechanical linkages, connecting cables, and hoses that move because you may get pinched, crushed, tangled, or dragged along with the equipment. High forces generated by the system can pinch, cut,

MTS Landmark™ Tabletop Load Units Product Information 21

Safety

or crush anything in the path of the equipment and cause serious injury. Stay clear of any potential crush points. Most test systems can produce sudden, high-force motion. Never assume that your reactions are fast enough to allow you to escape injury when a system fails.

Know the causes of unexpected actuator motions

The high force and velocity capabilities of MTS actuators can be destructive and dangerous (especially if actuator motion is unexpected). The most likely causes of unexpected actuator response are operator error and equipment failure due to damage or abuse (such as broken, cut, or crushed cables and hoses; shorted wires; overstressed feedback devices; and damaged components within the servocontrol loop). Eliminate any condition that could cause unexpected actuator motion.

Do not use RF transmitters

Keep radio frequency (RF) transmitters away from the workstation computers, remote terminals, and electronics consoles. Intense RF fields can cause erratic operation of the more sensitive circuits in the system.

Load Unit Hazard Labels

Two sets of labels are used for the load frames: one set for North America and one set for rest of the world.

Introduction

EC Declaration of Conformity (Machinery Directive 2006/42/EC Annex II 1A)

The load units are used for testing materials and components and can perform tension, compression, fatigue and fracture mechanics tests. The testing materials and components (test specimens) are supplied by customers or end users.

A combination of one each of an MTS load unit AND one each of an MTS Controller constitute machinery that can be used for specific application(s) as given in this load unit Product Information manual. If the load unit is supplied with an MTS Controller, the Declaration of Conformity is supplied with the machinery; an example of the Declaration of Conformity is provided at the end of this manual.

Optional equipment such as hydraulic service manifolds, a hydraulic power unit, grips, fixtures, extensometers, furnaces, ovens and environmental chambers, and so forth can be used with the machinery. MTS will supply Product Information manuals for optional equipment that allow such equipment to be assembled correctly with the load unit and controller. This will allow the completed system assembly of individual equipment to be controlled as one final machinery.

Declaration of Incorporation (Machinery Directive 2006/42/EC Annex II 1B)

If the load unit is supplied by itself, MTS will only supply a Declaration of Incorporation with the product; an example of the Declaration of Incorporation is provided at the end of this manual. Whenever a Declaration of Incorporation is supplied, it is the responsibility of the customer to perform the Machinery Directive Conformity Assessment procedures and ensure that the complete assembly of machinery sub-systems (load unit, controller, and optional equipment such as hydraulic service manifolds, hydraulic power unit, grips, fixtures, extensometers, furnaces, ovens and environmental chambers, and so forth) conforms to the requirements of Machinery Directive 2006/42/EC and other applicable EC Directives. This will require the customer to affix the CE Marking on the system assembly and to complete the EC Declaration of Conformity before putting the machinery into service.
