Tytron™ 250 Load Unit Component Identification Component Identification The following table describes the components that make up the load unit. Cable Connections Actuator Assembly Actuator Displacement Gage (optional) Force Transducer Reaction Fixture Base J1 Motor J2 Hall J3 LVDT J5 Encoder J4 Interlock Instrument Air 6 to 8 bar 634.08X-3X S/N 1234567 l Component Descriptions (part 1 of 2) COMPONENT DESCRIPTION Cable Connections The cable panel includes connections to the power amplifier and controller. See “Connecting Cables” on page 46 for more information. The connections are: • The DC linear motor • The Hall effect devices (HEDs) • The actuator displacement from the linear variable differential transformer (LVDT) to the controller • A connection to the interlock chain of the controller • Provisions for an optical linear encoder (a future option) The panel also includes a ground point and a connection for the air supply. Actuator Assembly Tytron™ 250 Load Unit The actuator assembly houses the following: • The DC linear motor with integral HEDs • Air bearing assembly • The LVDT • The air regulator • The air-pressure interlock switch • The wiring harness Introduction 15 Component Identification Component Descriptions (part 2 of 2) COMPONENT DESCRIPTION Actuator The actuator incorporates the armature of a DC linear motor. It slides in and out of the actuator assembly. Air-film bearings support and guide the actuator, allowing it to slide freely in and out. The actuator moves when the motor coils are sequentially energized by the linear motor drive. Displacement Gage This optional transducer measures small displacements with high resolution. The device can engage the actuator at any point in the actuator’s 100-mm displacement. Force Transducer The force transducer (sometimes called a force sensor or load cell) can be attached to the reaction fixture or to the end of the actuator. The force sensor measures how much force is being applied to the specimen. It can measure both tension and compressive forces. The force sensor is connected to a DC conditioner in the system controller. Base The base accepts the actuator assembly and the reaction fixture. The base material is a high-damping cast polymer composite that absorbs frame vibrations. A T-slot allows the reaction fixture to be positioned at any point in the 500-mm test area. Reaction Fixture The reaction fixture completes the drive train (which consists of the components between the actuator and the reaction frame). It is mounted to the T-slot of the baseplate. It is moved along the T-slot to accommodate the length of the test specimen or accessories. The force transducer or other fixtures can be mounted to the reaction fixture. See “Accessories” on page 61 for related information. Air Filtration Dry filtered air is used to supply the air-film bearing within the actuator assembly. There are three options for providing air of the necessary quality. See “Air Supply Specifications” on page 21. (not shown) Motor Drive (not shown) 16 Introduction The motor drive is a remote chassis that processes the command signal from the system controller to drive the DC linear motor in the load unit. The motor driver has no operator controls except a power switch. Tytron™ 250 Load Unit Functional Description Functional Description The Tytron 250 Load Unit uses a DC linear motor as a force generator within the actuator assembly. The actuator incorporates an air-film bearing for near frictionfree operation. The load unit requires a motor drive to process the test command from the system controller and create a motor drive signal. Depending on the control mode chosen, the force transducer, displacement gage, or linear variable displacement transducer (LVDT) will provide the feedback signal to the system controller. The controller compares the desired test profile with the appropriate sensor feedback signal and generates a motor command signal. The command signal (processed by the motor drive) drives the linear motor to match the test profile. Load unit The load unit includes the actuator assembly, the base, the reaction fixture, and a force transducer. The actuator assembly consists of a DC linear motor integrated with an air-film bearing, and a displacement transducer. The base is a highdamping cast polymer composite with an integral T-slot plate. The cast iron reaction fixture can be positioned at any point along the T-slot while maintaining alignment between the actuator and load cell. The force transducer mounts either on the reaction fixture or on the actuator. The T-slot also allows for a variety of specimen fixturing and accessory mounting schemes. An internally mounted LVDT monitors the position of the actuator. The LVDT is an electromechanical device that provides an output voltage that is proportional to the position of its movable core (which moves with the actuator). As the actuator moves, the output from the LVDT indicates how far the actuator has moved from a zero reference point (its center, or null position). An optional highresolution displacement transducer provides a more precise positioning capability. The linear motor contains integral Hall effect devices (HEDs) that provide the motor drive with accurate commutation information. This ensures smooth operation with extremely low velocity and force ripple. Motor drive The motor drive unit amplifies the analog command generated by the system controller, and creates a motor drive signal. The drive also uses the output from the HEDs to commutate the motor. Commutation is the process by which the drive provides the correct current, in the correct direction, in the correct winding, at the correct time to produce mutual attractive and repulsive forces between the motor’s windings and magnets that combine to create smooth motion. ON FFO X AXIS Tytron™ 250 Load Unit Introduction 17 Functional Description Force transducer 634.08X-3X The transducer assembly is attached between the moving and stationary portions of the actuator assembly. The stationary side is attached below the actuator. The moving portion engages with a horizontal probe within the actuator. This allows the transducer to be engaged with the actuator at any location along its 100-mm stroke length. The transducer has a bidirectional breakaway feature that disengages the device if the actuator overtravels, preventing transducer damage. S/N 1234567 The optional high-resolution displacement gage measures the displacement of the actuator during a test. l Displacement gage assembly (optional) The force transducer (sometimes called a load cell) measures the tensile or compressive forces being applied to the test specimen. It can be attached either to the reaction fixture, or the end of the actuator. The load cell is connected to a conditioner in the system controller. Because the Tytron 250 System is configured to run horizontally, the load cells used with the system will experience both bending and off-axis shear due to the mass of any grip, fixture, and specimen. This bending moment and off-axis shear is in addition to any loads, both static and dynamic, imposed directly on the specimen. As these load cells are very sensitive, there are limits to the amount of mass that can be installed on the force transducer. Do not exceed these rules of thumb without consulting the Tytron 250 group at MTS. Two types of load cells are used with the system. The normal system load cell (calibrated for ±250 N) is a symmetric bending beam cell, where orientation is not important. (It can be rotated without changing its ability to withstand a side moment.) The lower force cells (calibrated for ±25 N and ±5 N) are overloadprotected S-Beam cells that must be orientated on the system with the long axis vertical. If this is not done there is little ability to withstand off-axis moments. LOAD CELL CALIBRATION MAXIMUM SAFE MOMENT EXAMPLE OF THAT MOMENT 661.11B-02 ±250 N 2.26 N·m (20 in·lb) 3 kg mass centered 75 mm (6.6 lb at 3 in) from the load cell face. 661.09B-22 ±25 N 1.49 N·m (13.2 in·lb) 2 kg mass centered 75 mm (4.4 lb at 3 in) from the load cell face. 661.09B-20 ±5 N 0.373 N·m (3.3 in·lb) 500 g mass centered 75 mm (1.1 lb at 3 in) from the load cell face. 18 Introduction Tytron™ 250 Load Unit Functional Description Air supply/filtration The air-film bearing within the actuator assembly requires very clean and dry air to function properly. Three options are available for providing air of the required quality. • A simple connection kit where the on-site compressed air meets the required specification. • A filter/dryer kit where the on-site compressed air needs to be brought up to the required specification. • An air supply kit where there is no on-site compressed air supply (or the available air supply is poor). CAUTION Do not operate the load unit with the air supply off, or with poor quality air. Doing so can permanently damage the actuator. Be sure to use a clean, dry, and reliable air supply. For the requirements of the air distribution system, see “Air Supply Specifications” on page 21.

The quality of the air supply is critical for long and trouble-free performance. The bearing requires a consistent source of clean, dry air. Poor air quality will cause the small orifices in the bearing to erode or become clogged, causing damage to the air bearing. CAUTION Do not operate the load unit with the air supply off, or with poor quality air. Doing so may permanently damage the actuator. Be sure to use a clean, dry, and reliable air supply. There are three options for suppling air to the Tytron 250 load unit: Air Interface Kit Tytron™ 250 Load Unit • Air Interface Kit (part number 053-317-701) for existing, clean air • Air Filtration Kit (part number 053-317-801) filters existing air • Air Supply Kit (part number 053-317-901) supplies clean air This interface provides an on/off valve, quick connect fittings, and hose. Use this option when the air available on-site meets the following specifications. PARAMETER SPECIFICATION Pressure 7 to 8 bar (100 to 115 psi) Flow rate (minimum) 128 L/min (4.5 scfm) Maximum particle size 0.05 micron or less Maximum oil content 0.1 mg/m3 Maximum atmospheric dew point -20°C (-4°F) or less Introduction 21 Specifications Air Filtration Kit Air Supply Kit This kit provides air filtration and desiccation. It includes an on/off valve, air filters, an air dryer, quick connect fittings, and hose. The air filtration system is not intended to filter and dry excessively wet, dirty, or oily air. Use this option when the air available on-site does not meet the above criteria, but does meet the following specifications. PARAMETER SPECIFICATION Pressure 7 to 8 bar (100 to 115 psi) Flow rate (minimum) 128 L/min (4.5 scfm) Maximum particle size 40 micron or less Maximum oil content 5 mg/m3 Maximum atmospheric dew point -15°C (5°F) or less This kit provides compressed air, air filtration, and desiccation. It includes an air compressor, an on/off valve, air filters, an air dryer, quick connect fittings, and hose. It requires 230 V AC (8.2A), single phase, of 50 or 60 Hz power. Use this option when air is not available, or cannot meet the criteria of the other kits. Dry nitrogen gas could be used instead of compressed air. In this case, you may still need filtration to meet the particulate specification, though moisture and oil content should not be a problem. The capacity of the supply system is also a consideration, as a bottle of compressed gas has a finite lifetime at the required flow rate. The best application of this would be an existing building-wide nitrogen system supplied from a large liquid nitrogen Dewar, or a nitrogen gas generator. 22 Introduction Tytron™ 250 Load Unit Specifications Dimensions The following figure and table show the dimensions of the load unit. k a b c e g d f h i j Tytron™ 250 Load Unit I.D.

When you prepare to operate the system and during system operation, ensure the following: 26 Safety Information • Do not use or allow personnel to operate the system who are not experienced, trained, or educated in the inherent dangers associated with high-performance test equipment and who are not experienced, trained, or educated with regard to the intended operation as it applies to this test system. • Do not disable safety components or features (including limit detectors, door switches, or proximity switches/detectors). • Do not attempt to operate the system without appropriate personal safety gear (for example, hearing, hand, and eye protection). • Do not apply energy levels that exceed the maximum energies and velocities for the system design. Refer to the system specifications. • Do not use specimens that are combustible, flammable, pressurized, or explosive. • Do not modify the system or replace system components using parts that are not MTS component parts or effect repairs using parts or components that are not manufactured to MTS specifications. • Do not operate the system in an explosive atmosphere. • Do not use the system in a test area where uncontrolled access to the test system is allowed when the system is in operation. Tytron™ 250 Load Unit Personnel Qualifications Personnel Qualifications WARNING System installation, maintenance, setup, and operation require specialized training. Improper installation, maintenance, setup, or operation of the system by unqualified personnel can cause death or injury to personnel and damage to equipment. Do not allow unqualified personnel to perform any of the system installation, maintenance, setup, or operating procedures. Installation, maintenance, setup, and operating procedures should only be performed by trained personnel. Tytron™ 250 Load Unit Safety Information 27 Hazard Zones Hazard Zones System Hazard Zones The area around and including the test system is considered hazardous. Generally, hazards result from motions that occur during system operation. However, there are latent forces, overturning, and settling/unexpected movement hazards that can occur prior to or after system operation, during specimen installation, or during maintenance and repair. The hazard zone includes the entire system and an additional area of at least 4 feet around the system perimeter. Whenever personnel enter this defined zone they should be outfitted with adequate and appropriate safety attire (for example, safety glasses). Never wear loose fitting clothing when in the test area. Crush zone Crush Point Hazards It is important to stay clear of any potential crush points when the system is operating. Know where the crush points are in your system and protect yourself and others from those crush points with appropriate safety devices. The following paragraphs describe crush points and precautions to take while working around crush points. Locations Precautions A crush point exists between the actuator and the reaction fixture (area shown above). Keep clear of any mechanical linkage that moves within a closed area. If the linkage should move (when the system starts or due to mechanical failure), very high forces can be present that could pinch, cut, or crush anything in the path of linkage movement. Never allow any part of your body to enter the path of machine movement or to touch moving machinery, linkages, cables, specimens, etc. These present serious crush points or pinch points. Unexpected motion can occur even when the machine is de-energized. 28 Safety Information Tytron™ 250 Load Unit Placards Placards Hazard Placard Placement Hazard placards contain specific safety information and are affixed directly to the system so they are plainly visible. Each placard describes a system-related hazard. When possible, international symbols (icons) are used to graphically indicate the type of hazard and the placard label indicates its severity. In some instances, the placard may contain text that describes the hazard, the potential result if the hazard is ignored, and general instructions about how to avoid the hazard Item (type) Icon Description 1 (hazard) Voltage hazard. High voltage exists in the vicinity where this icon is located.

Safety Information Tytron™ 250 Load Unit Lockout/Tagout Lockout/Tagout Identify Lockout/Tagout Points The purchase, installation, and use of electrical lockout/tagout devices is a customer responsibility. The purpose of these devices is to provide an effective means of isolating the test system from electrical power sources associated with your system. MTS recommends the use of an uninterruptible power supply (UPS) as an independent electrical power source. In addition, there should be a single point in the electrical supply that provides complete electrical isolation when a lockout/ tagout switch is installed. Before you make contact with any circuit, test the circuit with a properly operating circuit tester to ensure that power is off. Tytron™ 250 Load Unit Safety Information 31 Site Precautions Site Precautions WARNING The equipment is designed to operate in an environment where precautions have been taken to minimize hazards to personnel and the equipment. Ignoring hazards and failing to take necessary precautions can result in injury or death to personnel, and damage to equipment. Do not install or operate the system equipment in a hazardous environment. WARNING Hazardous situations or conditions can arise suddenly and without warning at all parts of the system. If immediate action is not taken to remove the hazard or remove personnel from the hazard, serious injury or death can result. Do not operate the system unless you have full view of the equipment. If operation of the system takes place in a remote control room (separated from the equipment), it should be designed so that the operator has full and unobstructed view of the system equipment. Make sure that ergonomic issues are considered in the layout of the operating area to limit operator stress and fatigue. 32 Safety Information Tytron™ 250 Load Unit Equipment Covers Equipment Covers WARNING Covers are designed to protect personnel from moving parts and electrical shock. If covers are not installed, potential hazards are exposed that can cause injury or death. Personnel can be struck, crushed, entangled, or drawn into moving parts; hit by flying objects launched with concussive force; electrocuted by exposed electrical conductors. Install all covers before applying electrical power and operating the system. Covers are tool secured and part of the machine.Ensure all covers are in place and secured before operation. Covers include: • Main cover • Rear cover • T-linear bearing cover • Top Cover Machine and procedural safeguards are essential for protecting workers from these preventable injuries. Any machine part, function, or process that can cause injury must be safeguarded. Do not operate without an enclosure. If the enclosure provided with the machinery does not accommodate the test specimens, then contact MTS for assistance. The test area enclosures are optional. If an enclosure is not purchased from MTS, then it is the responsibility of the user to affix an enclosure on the machinery. Tytron™ 250 Load Unit Safety Information 33 Safety Practices Safety Practices 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. Safety Practices Before System Operation Before you apply drive 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. 34 Safety Information Tytron™ 250 Load Unit Safety Practices 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 may require a complete understanding of system operation to avoid unsafe or dangerous situations. Locate and read hazard placards/labels Find, read, and follow the hazard placard instructions located on the equipment. These placards are placed strategically on the equipment to call attention to areas such as known crush points and electrical voltage hazards.. Locate Lockout/tagout points Know where the lockout/tagout point is for all of the electrical supply energies associated with 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 2 meters (6 feet) 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. 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. Keep bystanders safely away Keep bystanders at a safe distance from all equipment. Never allow bystanders to touch 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 Tytron™ 250 Load Unit Safety Information 35 Safety Practices fluid with a non-flammable fluid to maintain the proper proportion of weight and balance. Check bolt ratings and torques To ensure a reliable product, fasteners (such as bolts and tie rods) used in MTSmanufactured 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. Overtorquing or undertorquing 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. 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 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. 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. 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). 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. You need to see what you are doing. Safety Practices While the System Operates Wear appropriate personal protection 36 Safety Information Wear eye protection when you work with breakable specimens or when anything characteristic to the specimen could break apart. Tytron™ 250 Load Unit Safety Practices Wear appropriate protection ( 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 guards Specimen temperature changes Handle chemicals safely 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). During cyclic testing, the specimen temperature can become hot enough to cause burns. Wear personal protection equipment (gloves) when handling specimens. Whenever you use or handle chemicals (for example, 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 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 operation 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 machine 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 (for example, accelerometer, extensometer, load cell, displacement transduce, ) or its connecting cable when electrical power is applied. Ensure secure cables Do not change any cable connections when electrical power 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. 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, 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 Tytron™ 250 Load Unit Safety Information 37 Safety Practices assume that your reactions are fast enough to allow you to escape injury when a system fails. Do not use RF transmitters 38 Safety Information 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. Tytron™ 250 Load Unit Installation This section describes how to install the Tytron 250 Load Unit. Contents Installation Procedure 40 Installing the Air Supply/Filtration Kits Connecting Cables Tytron™ 250 Load Unit 43 46 Installation 39 Installation Procedure Installation Procedure 1. Unpack the load unit. A. Inspect the load unit for damage and report any damage to both the carrier and MTS. Contact your nearest MTS office. B. Finish unpacking the load unit. Screw the four included (M12 x 1.75mm thread) lifting eyes into the four threaded inserts in the base (two at each end). Use the eyes for attaching lifting straps or handles. The total weight of the load unit without the reaction fixture is about 160 kg (350 lbs). CAUTION Do not lift or position the load unit using the actuator. This will permanently damage the actuator. Use the eyes attached to each end of the chassis to lift and position the load unit. C. Place the load unit on a table or stand capable of supporting its full weight of 226 kg (500 lb). Remember that any accessories added to the system also add to the system weight. 2. Ground the components. The motor drive chassis and the system controller should be connected to the same fused power circuit. The motor drive chassis is configured at the factory for 100, 115, or 230 V AC applications. Each system has its own internal grounding system. The load unit should be grounded to the same point as the controller and the motor drive. A grounding wire is provided to tie the load unit assembly directly to a common grounding point. The ground on the load unit is marked on the cabling panel. 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 2-m copper grounding rod driven at least 2 m into the ground. Grounding must conform to local electrical codes. 3. Ensure the machine is level. A level can be placd on the main cover and 90 degree angles to measure the level lengthwise and widthwise of the machine. Use shims as required under the isolation pads or mounting table legs to level the machine. 4. Go to “Installing the Air Supply/Filtration Kits” on page 43 and install the appropriate kit. This section describes how to install each of the air supply/filtration options. 40 Installation Tytron™ 250 Load Unit Installation Procedure 5. Go to “Connecting Cables” on page 46 and make the electrical connections. This section shows the connections between the load unit, the motor drive, and the TestStar IIs controller. 6. Go to “Accessories” on page 61 and install the appropriate fixtures. The “Accessories” chapter describes how to install all of the optional components available for the load unit. Note Do not install the grips or furnace until you have aligned the reaction fixture to the actuator in the next step. After you install the fixtures, return to this procedure. 7. Align the force transducer to the actuator. The alignment tool lets you check the alignment between the actuator the force transducer. Mount the alignment tool to the force transducer and the actuator. Adjustment Bolt Force Transducer Alignment Fixture female Actuator male Setscrew Tytron™ 250 Load Unit A. Thread the cup-point end of the 16-mm setscrew into the force transducer. B. Thread the female alignment fixture onto the setscrew in the force transducer. C. Thread the cup-point end of the 20-mm setscrew into the male alignment fixture. D. Thread the male alignment fixture into the actuator. E. Turn the air supply on, but do not turn on the motor drive. The actuator can now be moved by hand. F. Manually move the reaction frame toward the actuator. Installation 41 Installation Procedure Note The actuator mount is not adjustable. All alignment adjustments are made at the reaction fixture. • If the two alignment fixtures mate, the load unit is aligned. • If the two alignment fixtures do not mate, the force transducer must be adjusted. The force transducer can be adjusted with the screw mounting it to the reaction fixture. The maximum torque for the mounting screw is 6.3 Nm (56 lb in). G. Remove the alignment fixture. H. Install the grips (or any other accessories). 8. Go to “Tuning Considerations” on page 53 to tune the control modes for the load unit. Note The force transducer, LVDT, and displacement gage should be calibrated before performing any tuning procedures. Sensors purchased from MTS Systems Corporation are usually already calibrated and include the calibration data in the sensor I.D. module-imbedded in the sensor cable. See your controller documentation for field calibration procedures. After the load unit is installed and before it is put into use, you must tune any control modes used with the load unit. Use the tuning procedures described in your controller’s manual and incorporate the tuning recommendations (see “Tuning Considerations” on page 53). 42 Installation Tytron™ 250 Load Unit Installing the Air Supply/Filtration Kits Installing the Air Supply/Filtration Kits Compressed air is used for the air-film bearings.

This load unit contains magnetic fields that can erase disks. Keep floppy disks and other magnetic media away from this load unit. CAUTION Always run the load frame with the air distribution system turned on. Running the load unit with the air distribution system turned off will permanently damage the actuator. Be sure to use a clean, dry, and reliable air supply. Note Tytron™ 250 Load Unit When the Tytron 250 Load Unit is used with a TestStar IIs controller, the HWI (hardware interface file) is configured at MTS Systems Corporation. If you change your test to run the MTS application software called “Fatigue and Fracture Cyclic Fatigue”, you will need to change the HPS Control definition. This definition is normally commented out; the definition must be reinserted when the HCF test is used. See the TestStar IIs Controller documentation for information about the tsiis.hwi file. Operation 49 Installing a Specimen Installing a Specimen Prerequisites Review the following prerequisites: • The load unit must have the appropriate fixtures installed for each test. Go to “Accessories” on page 61 and install the appropriate fixtures. The “Accessories” chapter describes how to install all of the optional components available for the load unit. • The force transducer and the actuator must be aligned. Perform Step 7, “Align the force transducer to the actuator.” on page 41 whenever you change the fixtures. • All transducers must be calibrated and tuned. 1. Turn on the load unit. Turn on the electrical power to the motor drive. This also powers the load unit. Air is supplied to the load unit from an inhouse air compressor. Be sure the air compressor is running. Also open the shutoff valve to supply air to the load unit. On OR Off 2. Set the actuator position. For normal operation set the actuator to mid-displacement (use your controller). The actuator position is not critical but it must allow the maximum displacement of a test. Reasons to change the actuator position include the following: • If the test requires a longer displacement than mid-displacement can accommodate, reposition the actuator as needed. • If the test area (such as the length of the test specimen) requires the actuator to be moved, reposition the actuator as needed. 3. Adjust the reaction fixture on the T-slot. The reaction fixture can be slid along the T-slot imbedded into the load unit. Position the reaction fixture so there is enough room for the force sensor, test fixtures or grips, and a specimen. The position is not critical since the actuator can be moved to finish the specimen installation. Tighten the locking screw to clamp the reaction fixture in place. The maximum torque for the locking screw is 45 Nm (33 lb ft). SN KN FORCE TRANSDUCER l MODEL 661. CAPACITY LBS Reaction Fixture Adustment Range Locking Screw 50 Operation Tytron™ 250 Load Unit Installing a Specimen 4. Install the specimen. Mount the specimen into the grip or fixture of the reaction fixture (using the method required by the grip or fixture). Adjust the actuator so you can mount the other end of the specimen into the grip or fixture attached to the actuator. 5. If necessary, attach the displacement gage. If you have the optional displacement gage and want to use it for the test, complete this step. The actuator must be in its final position before the test. Note You will be working in a crush zone. Set the displacement interlock limits for the LVDT at your controller.

Insert the installation tool into the hole on the displacement gage attachment and pull the retaining pin to the detent (this connects the displacement gage attachment to the assembly). E. Remove the installation tool. F. Tighten the clamping screw until contact with the clamping block is made and tighten 1/2 additional turn (do not over-tighten). CAUTION Do not proceed without removing the zero pin and the installation tool. Operating the load unit with the zero pin or the installation tool installed will damage the extensometer. Remove the zero pin and the installation tool before proceeding. G. 52 Operation Remove the zero pin. Tytron™ 250 Load Unit Tuning Considerations Tuning Considerations Tuning the Tytron load unit is different from tuning a servohydraulic system. This is due to the difference in the way the actuator works. A servohydraulic actuator moves due to changes in fluid pressure on either side of a moving piston. The velocity of the moving actuator is dependent on the fluid flow rate into (and out of) the actuator. Thus, the actuator’s velocity is proportional to the command signal applied to the servovalve. The Tytron actuator moves due to changes in the force developed by the linear motor inside it. The force generated by the motor is proportional to the command signal applied to the motor drive. Thus, the actuator’s acceleration is proportional to the command signal applied to the motor drive. For this reason, tuning must be done a little differently from conventional servohydraulic tuning methods. Prerequisite Procedure Set up your controller to monitor signals on an oscilloscope (if available), or use the scope supplied with the system controller software. Tune the load unit in the following order: Note Tuning a control mode can vary substantially if a specimen is installed or not installed. If possible, tune with no specimen first, and then tune with a specimen installed. 1. Tune displacement without a specimen installed. Go to “Tuning Displacement” on page 54 and complete the “Without a Specimen” procedure then return to this procedure when done. 2. Tune the extensometer without a specimen installed. Go to“Tuning Extensometers” on page 55 and complete the “Without a Specimen” procedure then return to this procedure when done. 3. Go to “Installing a Specimen” on page 50 and install the specimen then return to this procedure. 4. Go to“Tuning Force” on page 56 and complete the procedure then return to this procedure when done. Note Depending on your test requirements, complete the one or both of the following steps. 5. Tune displacement with a specimen installed. Go to “Tuning Displacement” on page 54 and complete the “With a Specimen” procedure then return to this procedure when done 6. Tune the extensometer with a specimen installed. Go to“Tuning Extensometers” on page 55 and complete the “With a Specimen” procedure then return to this procedure when done. Tytron™ 250 Load Unit Operation 53 Tuning Considerations Tuning Displacement When tuning displacement set up your controller as follows: Without a specimen • Select the most appropriate sensor range based on the test requirements. • The command waveform should be a 1 Hz ramp (triangle). • The waveform amplitude can be determined by using either the test amplitude or an amplitude equal to 10% of the selected range. • Initial PIDF settings are: P=1.0; I=0.5; D=0.025. • Monitor the LVDT transducer signal and the DC error signal. If a specimen is installed, monitor load. 1. Increase the P (proportional gain) parameter and D (derivative gain) parameter in small increments until the LVDT signal has a linear rise and fall. If the actuator is oscillating at first, increase D until the actuator has a smooth transducer output on the scope. The DC error signal response will have the appearance of a step or square wave. 2. P gain will affect the rising and falling edge of the DC error step. Increase the P gain term until slope of the rising and falling edges of the DC error signal no longer continues to increase. 3. The D gain will attenuate overshoot and ringing (ripple) on the top and bottom plateaus of the DC error signal. 4. The I (integral gain) tuning parameter will aid in adjusting the peak and valley levels symmetrically around the desired mean. Monitor the peak and valley level of the LVDT response and increase the I term until desired mean is obtained. Note With a specimen Tuning results at MTS Systems Corporation for displacement with no specimen are approximately P=2.0, I=1.5, and D=0.4. Tuning with a specimen will need increased amounts of “I” to gain good response. Tuning with a specimen varies according to the stiffness of the specimen. 1. Complete the tuning procedure without a specimen above. 2. With a specimen installed, verify that the load signal is stable when the actuator is holding at a static LVDT level. 3. Specimen insertion will occasionally cause the actuator to oscillate. Decreasing the D term is usually effective in minimizing the oscillations. Try to maintain the highest permissible D value possible. 4. If a dynamic test is to be performed using LVDT control, it may be necessary to increase the I gain to obtain the desired peak and valleys. Exercise the specimen at the expected test end levels and increase the I term to minimize the end level errors. 54 Operation Tytron™ 250 Load Unit Tuning Considerations Tuning Extensometers The extensometer control mode can be tuned with or without a specimen installed. Set up your controller as follows: Without a specimen • Select the most appropriate sensor range based on the test requirements. • The command waveform should be a 1 Hz ramp (triangle). • The waveform amplitude can be determined by using either the test amplitude or an amplitude equal to 10% of the selected range. • The initial PIDF settings are: P=1; I=0.25; D=0.1. • Monitor the displacement gage signal and the DC error signal. Some extensometers (such as a displacement gage) can be tuned without a specimen. 1. Increase the P (proportional gain) parameter and D (derivative gain) parameter in small increments until the displacement gage signal has a linear rise and fall. If the actuator is oscillating at first, increase D until the actuator has a smooth transducer output on the scope. The DC error signal response will have the appearance of a step or square wave. 2. P gain will affect the rising and falling edge of the DC error step. Increase the P gain term until slope of the rising and falling edges of the DC error signal no longer continues to increase. 3. The D gain will attenuate overshoot and ringing (ripple) on the top and bottom plateaus of the DC error signal. 4. The I (integral gain) tuning parameter will aid in adjusting the peak and valley levels symmetrically around the desired mean. Monitor the peak and valley level of the displacement gage response and increase the I term until desired mean is obtained. 5. Complete the tuning procedure with a specimen below. With a specimen Some extensometers (such as a clip on gage) must be tuned with a specimen installed. You will also need to monitor the load signal in this procedure. Tuning with a specimen will need increased amounts of “I” to gain good response. 1. With a specimen installed, verify that the load signal is stable when the actuator is holding at a static displacement gage level. 2. Specimen insertion will occasionally cause the actuator to oscillate. Decreasing the D term is usually effective in minimizing the oscillations. Try to maintain the highest permissible D value possible. 3. If a dynamic test is to be performed using displacement gage control, it may be necessary to increase the I gain to obtain the desired peak and valleys. Exercise the specimen at the expected test end levels and increase the I term to minimize the end level errors. Tytron™ 250 Load Unit Operation 55 Tuning Considerations Tuning Force When tuning force (also called load), a specimen must be installed. Set up your controller as follows: • Select the most appropriate sensor range based on the test requirements. • The command waveform should be a 1 Hz ramp (triangle). • The waveform amplitude can be determined by using either the desired test amplitude or an amplitude that is equal to 25–50% of the maximum load expected during the test. • Excite the specimen with a test command from the controller that best represents the type of test being performed (such as tension/tension, compression/compression, or tension/compression). • The initial PIDF settings are: • – For a stiff specimen (carbon fiber) P=0.1; I=50.0; D=0.001 – For an elastic specimen (plastic or mylar) P=5.0; I=5.0; D=1.0. – For a very elastic specimen (rubber) P=50.0; I=5.0; D=2.5. Monitor the force transducer signal and the DC error signal. Specimen stiffness has a direct bearing on the tuning parameters. • Stiff specimens may have I parameters as high as 4,000 to 8,000, P gains of 0.2, and D gains of 0.002. • Softer, more elastic specimens tend to have increased P and D terms and less I gain (such as P might be 400 while I is 3000). Generally speaking, stiff specimens have larger integral (I) gain parameters and softer specimens tend to have increased proportional (P) gain and smaller amounts of I gain. 1. Begin by increasing the I parameter to create a step or square wave response for the DC error signal. You will also notice that the load signal will have linear rising and failing slopes resembling the command. 2. The sharpness of the slope for the DC error can be increased by adding P gain. As a result of increased proportional gain (P), the top and bottom plateaus of the DC error signal will show signs of overshoot and ripple. Increase the D gain to minimize the overshoot and ripple present on the DC error signal. 56 Operation Tytron™ 250 Load Unit Maintenance This section covers the procedures that must be periodically performed for reliable and effective operation of the Tytron 250 Load Unit. Contents Tytron™ 250 Load Unit Inspecting the Load Unit 58 Renewing the Filter Elements 59 Cleaning and Preventing Rust 60 WHAT TO DO WHEN TO DO IT Inspect daily Before the start of each day’s testing.

Filter elements must be replaced whenever there is a noticeable drop in the output of filtered air. • The first filter is a coalescing filter that cannot be cleaned. The filter has an indicator that pops up when the it is dirty. Replace the filter when the dirty filter indicator pops up (part number 100-002-283). • The second filter is a general 5-micron filter. It does not have a dirty filter indicator. Wash the filter with mild soap every 6–9 months. It can be cleaned 3 or 4 times before replacement (part number 100-002-284). • The air dryer unit does not have a replacement filter. Replace the entire unit every two years (part number 011-973-109). Coalescing Filter General Filter Air Dryer • Tytron™ 250 Load Unit The filter replacement kit (part number 100-002-145) includes all of the filters described above.

Grips hold each end of the specimen. One grip is mounted to the actuator and the other is mounted to the force transducer. Mechanical clamp grips This mechanical clamp grip is rated for 250 N. • 64 Accessories Each grip weighs 21.3 g (0.75 oz). • The mounting thread size and pitch is M6 x 1 mm. • The grips can clamp a specimen no larger than 25.4 x 1.6 mm (1 x 0.063 in). 25.4 mm 1.6 mm Tytron™ 250 Load Unit Displacement Gage Displacement Gage The displacement gage can be mounted below the actuator. The displacement gage assembly is attached to the load unit with two screws. A fixture for the displacement gage is mounted on a shaft in the actuator. Once the actuator is in its starting position, the displacement gage attachment can be slid along the mounting rod and positioned above the displacement gage assembly (where the two components can be mated). The clamping screw presses a metal clamping block to the mounting rod to secure the assembly. This procedure installs the displacement gage fixture onto the actuator mounting rod and installs the displacement gage assembly to the load unit. 1. Loosen the clamping screw of the displacement gage attachment. 2. Unscrew the attachment mounting rod and slide it out just enough to allow the displacement gage attachment to be slipped over the end. CAUTION The clamping block (located in the displacement gage attachment) can slip out of its mounting and into the interior of the actuator assembly. The clamping screw can damage the ceramic mounting rod if the clamping block is not present. Be sure the clamping block remains in its mounting when moving the displacement gage attachment. 3. Slide the mounting rod into the displacement gage attachment. Then, insert the mounting rod back into its original position and tighten it. Tytron™ 250 Load Unit Accessories 65 Displacement Gage Note Leave the clamping screw loose so the displacement gage attachment can be repositioned on the attachment mounting rod later.

To mate the displacement gage attachment to the displacement gage assembly, go to Step 5 on page 51 in the “Installing a Specimen” section. Note When the displacement gage is not in use, move the displacement gage attachment to the front of the actuator. Tighten the clamping screw (do not over-tighten). Now the actuator can move freely without the attachment interfering with the displacement gage assembly. CAUTION Do not over-tighten the clamping screw. The metal clamping block can damage the ceramic mounting rod if it is over-tightened. Tighten the clamping screw just enough so the displacement gage attachment does not slide on the mounting rod. Tytron™ 250 Load Unit Accessories 67 Fixtures Fixtures Fixtures are mounting options that allow you to customize the possible ways you can mount a specimen. X-Y fixture The X-Y fixture lets you adjust the x and y axis of the fixture. It consists of two adjustable fixtures mounted together (horizontal and vertical). The two fixtures can be separated and used individually. Reaction Fixture Vertical Adjustment Horizontal Adjustment Angle Bracket Additional stages of fixtures or a force transducer. Side View Front View 68 Accessories Tytron™ 250 Load Unit Fixtures Theta stage The theta stage lets you compensate for specimens that may not be flat. The knob lets you rotate clockwise or counterclockwise one end of the specimen to compensate for any natural twist in the specimen. The theta stage fixture can be mounted directly to the reaction fixture or as a stage mounted on the X-Y fixture. Tytron™ 250 Load Unit Accessories 69 Test Chambers Test Chambers Test chambers are compartments designed to emulate a specific environment. Environmental chamber The environmental chamber provides a temperature regulated environment for the Tytron 250 Load Unit. It can provide an air temperature range of -75° to +200°C (-100° to +390°F). The chamber is mounted to a pan which attaches to the T-slot of the load unit (the pan also functions as a drip pan to protect the load unit). Water cooled extension rods are needed to reach inside the chamber where grips can be mounted. The water cooled extension rods are supplied in one size and can be cut to length to accommodate a variety of specimen sizes.
