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.
Safety 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. Locate lockout/tagout points Know where the lockout/tagout point is for each of the supply energies associated with your system.
Safety 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.
Safety • 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.
Safety (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.
Safety 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.
Safety 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.
Safety Hazard Warning Icons The following hazard warning icons indicate hazards that can result in personal injury or equipment damage when using the MTS Criterion Series 40 systems. They are typically placed on or near the area of concern. They are intended to alert the user to possible hazardous conditions or hazardous situations. Hazard Warning Icons Icon Description Do not start, operate, or service the machine until you read and understand the operator's manual.

Key Concepts Topics: • • • • • • • • About This Chapter............................................................................................................................46 Understanding Your MTS Software...................................................................................................46 Understanding MTS Applications and File Types..............................................................................47 Understanding the Control Loop........................................
Key Concepts About This Chapter This chapter, as well as the information in the Safety Chapter, contains information you should know before you attempt to run tests with your MTS Criterion Series 40 System. This information applies to the typical system used as an example in this manual. For information that applies to other system configurations or tests, see: • • The "Best Practices for Other System Configurations and Tests" chapter in this manual.
Key Concepts Item Description 1 All MTS TestSuite Applications 2 MTS TW Express It is important to understand that to run tests on your station, the only MTS TestSuite software you need is the MTS TW Express application (or TWX for short). Note: The MTS TW Elite application can be configured for operators. In that configuration, it has the same capabilities as the MTS TW Express application.
Key Concepts File Type Description Test Template Files Test Template files are command files created with TW Elite for performing tests. Test Template files contain only test definition information. MTS TestSuite Test Template Icon Test Procedure Files Test Procedures files are similar to Test Template files, but include a container that stores test data and results.
Key Concepts Item Description 1 Feedback 2 Controlling Element 3 Controlled Element 4 Command The controlling element is the computer, the MTS Insight controller, and the MTS TW application. The controlling element produces a control signal (Command) that represents the direction and amount of extension you desire to apply to the crosshead. The controlled element comprises the motor, the crosshead, and the specimen itself.
Key Concepts 3. The MTS Insight controller generates this command and sends it to the crosshead drive motor, which moves the crosshead. 4. The load frame-mounted sensors send back a signal indicating the new position. 5. The encoder senses the amount of extension and sends this feedback to the digital controller, where it is compared with your command. The system automatically repeats Steps 2 through 5 until the desired command is achieved.
Key Concepts Using the Emergency Stop Control If something unusual occurs that requires immediate action, use the Emergency Stop (E-Stop) control to: • • Stop whatever setup operation or test you have in progress, and Set the interlock. While using your system, always keep in mind where the E-Stop control is and what it does. The E-Stop is a large red button on a yellow background and is located on the LUC (load unit control) module.
Key Concepts Typical Components in the Load Train Item Name Description 1 Crosshead Moves up or down to impart force on the specimen. 2 Force Sensor (Load Cell) Measures the force imparted on the specimen. The force sensor can also be mounted to the base. 3 Adapter Provides a means for quickly mounting the grip to the load cell or base. 4 Pin Secures the grip to the adapter. 5 Locking Ring Must be tightened to eliminate play from the load train.
Key Concepts Resolving Interlock and Error Conditions Resolving interlock and error conditions is a normal part of operating an MTS Criterion System. You typically identify and resolve these type conditions during setup and testing. Identifying an Interlock Condition When you launch the MTS TWX application and open a test, the test opens in an interlocked state by design.
Key Concepts The status panel can be very helpful in determining what is causing an interlock condition. Using the Application Log to Identify Error Conditions The MTS TestSuite TW application is equipped with a log to help you identify error conditions. The log is your window into the state of the system, and your information center for the source of error conditions. Each log entry is categorized with keywords such as “ Warning” and “Error” to inform you if intervention is required.
Key Concepts Note: The Application Log is found in the lower right corner of the main TW screen. You may need to expand the bottom panel to see it.
Running the Example Tension Test Topics: • • • • • • • • • • • • • • • • Overview............................................................................................................................................58 Safety Orientation..............................................................................................................................58 Turn on the Station.........................................................................................................................
Running the Example Tension Test Overview This chapter describes how to run a typical tension test using the typical system described in the System Introduction (p. 23). For information on how to adapt the following information for using other hardware configurations or running other tests, see Best Practices for Other System Configurations and Tests (p. 115). The instructions that follow use the MTS EM Tension (Simplified) test. This test does not use an extensometer.
Running the Example Tension Test Warning: Crush zones exist above and below the crosshead. Body parts can be crushed by the moving crosshead. Keep all body parts clear of the crush zones when moving the crosshead. • Emergency Stop button Use the Emergency Stop button to stop a test immediately. Turn the Emergency Stop button clockwise to reset the interlock.
Running the Example Tension Test There is an interlock on the door that prevents running a test with the door open. • Equipment and software. It is important to read the System Introduction (p. 23) to familiarize yourself with the equipment and software prior to testing. Turn on the Station 1. Turn on the computer. 2. Turn on the load frame using the power switch located on the right side of the load frame.
Running the Example Tension Test 3. Open the MTS TW Express application.

Select the test. • If you will not be using an extensometer, from the TWX menu bar select File > New > Test from Template > MTS Templates > TW – EM > MTS EM Tension (Simplified) but do not click the green arrow (Run) button yet.
Running the Example Tension Test Reset Interlocks Your MTS Criterion test system performs many self-checks when it is powered up. The interlock is always set on initial startup. In addition, if a safety condition is violated, the system also sets an interlock. The interlock indicators light (see below) and the interlock renders the machine inoperable until the violated safety condition is corrected. It is normal to encounter interlock conditions during normal operation.
Running the Example Tension Test The status window appears. Tripped interlocks are indicated with red boxes. (The two interlock conditions shown below are normal after startup.) 2. Correct any interlock conditions and then reset the interlock. Click the Reset button in the Controller panel. Set Travel Limits Setting the travel limit stops to positions just outside expected test crosshead travel helps prevent equipment damage and injury.
Running the Example Tension Test Note: The limit stops are not intended to be the routine method to end every test. Warning: Moving the limit stop when the limit is tripped disables the hardware interlock and may result in unexpected motion. Unexpected motion may cause injury or equipment damage. Do not move the limit stop while the crosshead is tripping the limit. If you inadvertently move the limit with the crosshead contacting it, the crosshead may begin to move.
Running the Example Tension Test Use the same method as described in the previous step. Recover from a Tripped Travel Limit This procedure is included as reference for times when you encounter a tripped limit. If you do not currently have a tripped limit, you can skip this procedure. Warning: Moving the limit stop when the limit is tripped disables the hardware interlock and may result in unexpected motion. Unexpected motion may cause injury or equipment damage.
Running the Example Tension Test 2. Use the Crosshead Up or Crosshead Down button to move the crosshead away from the limit stop. b) Use the handset to move the crosshead away from the limit stop. 1. Reset the Interlock and enable the handset by pressing the Handset Enable button twice. 2. Use the Crosshead Up or Crosshead Down button to move the crosshead away from the limit stop.
Running the Example Tension Test c) Once the crosshead is repositioned clear of the limit stop, move the limit stop to the desired position on the load frame. Loosen the stop by turning counterclockwise, move to the desired position, and then tighten by turning clockwise. Position the Crosshead 1. Ensure that the computer and load frame are on and that TWX is running.
Running the Example Tension Test 2. Use Step a or b together with c if necessary to move the crosshead to the desired location. a) Use the TWX crosshead controls to position the crosshead. b) Use the Handset to position the crosshead. 1. Enable the handset by pressing the Handset Enable button on the handset. 2. Use the Crosshead Up and Down controls to move the crosshead to the desired position.
Running the Example Tension Test c) If a travel limit stop prevents movement, see Recover from a Tripped Travel Limit (p. 66). Set Up the Load Meter for Specimen Installation This procedure is performed to ensure that the forces imparted on the specimen during installation are acceptable and have not damaged the specimen. 1. If necessary, expand the meter area at the bottom of the window by clicking the small expand tab in the lower center of the window. 2. Select the desired units.
Running the Example Tension Test For this example, select mm for the Crosshead meter. Right-click the Crosshead meter and select Unit > mm. 3. Change the load Meter Type to Running Maximum/Minimum. Right-click the meter labeled “Load” and select Meter Type > Running Maximum/Minimum. You will use this meter to monitor the maximum and minimum forces imparted on the specimen during installation to ensure that the specimen is undamaged at the conclusion of specimen installation. 4. Zero the load meter.
Running the Example Tension Test Install the Specimen Warning: Specimen installation requires working in the crush zone. Unexpected crosshead movement can cause injury or equipment damage. Use caution when working in the crush zone and moving the crosshead. 1. Position the crosshead using the handset or software crosshead controls. Ensure that there is adequate clearance for the specimen. For control instructions, see Position the Crosshead (p. 68). 2. Install the specimen in the upper grip.
Running the Example Tension Test b) Insert the specimen. Ensure that the specimen is properly aligned to avoid introducing any side loading. Also ensure that the specimen has contact across the entire face of the grip. c) Clamp the specimen by releasing the lever. Ensure that there is a slight gap (A) between the end of the specimen and the grip.
Running the Example Tension Test 3. Install the specimen in the lower grip. a) Open the lower grip. b) Lower the specimen in the lower grip using the handset or software crosshead controls.
Running the Example Tension Test For control instructions, see Position the Crosshead (p. 68). c) Clamp the specimen. When the specimen is properly aligned, release the lever to clamp the specimen. d) Ensure that the specimen has a slight gap (A) between the end of the specimen and the grip so as not to preload the specimen.
Running the Example Tension Test Install the Extensometer (Optional) This section requires use of a template that supports an extensometer such as the MTS EM Tension (Extensometer-Crosshead) template. If you are using a template that does not use an extensometer, skip this section. Warning: Specimen installation requires working in the crush zone. Unexpected crosshead movement can cause injury or equipment damage. Use caution when working in the crush zone and moving the crosshead. 1.
Running the Example Tension Test 2. Plug in the extensometer cable. Plug the rectangular end of the extensometer cable into the J9 port on the right side of the load frame. 3. From the TWX main window, select Controller > TEDS Devices.
Running the Example Tension Test The TEDS Devices window appears. 4. Select the TEDS file for the extensometer you are using. Select the _Strain1 row, and then click Assign. The TEDS Devices window shows the available TEDS files. Select the appropriate TEDS file for the extensometer you are using. 5. If necessary, verify the device. You may be asked to verify the TEDS device. If so, click Verify. You may need to take action if the TEDS device cannot be verified.
Running the Example Tension Test 8. Make sure that the extensometer is completely closed. 9. Zero the extensometer meter. Right-click the Extensometer meter and select Zero Signal.
Running the Example Tension Test Set Up Meters for the Test 1. Ensure that the forces that were imparted on the specimen during specimen installation are acceptable. For example, the plastic specimen used in this example test could tolerate installation forces up to 1.5 kN before permanent deformation would result. Because the Running Maximum/Minimum meter read only .007 kN tension and .008 kN compression at the conclusion of specimen installation, it is safe to say that the specimen has not been damaged.
Running the Example Tension Test If Required, Resolve Resource Errors If you do not have any resource errors, you can skip this step. Resource errors occur if the resources in the software do not match the resources for the station. TWX indicates resource errors with a white “x” encircled in red. 1. Search for resource errors in TWX. Check the main tabs for white “x”s encircled with red. 2. If you find a resource error, search the tabs until you find the root cause of the resource error.
Running the Example Tension Test 3. Correct the mismatch between software and station resources. If necessary, contact MTS for technical assistance.

Best Practices for Other System Configurations and Tests Mount the Load Cell (Force Sensor) If necessary, mount the load cell. 1. Mount the load cell to the crosshead. Be sure to compare the length of the load cell bolt to the depth of the load cell hole. Make sure the bolt will not bottom out to avoid damaging the load cell. 2. Electrically connect the load cell to the load frame. 3. Connect the cable from the load cell to the load frame.
Best Practices for Other System Configurations and Tests Mount the Grips A wide range of grips are available. The procedure that follows shows typical grip installation. Warning: Grips are heavy. Dropping the grip could cause injury or equipment damage. Be sure to support the grip when working with the grip pin. 1. Mount the load frame adapter.
Best Practices for Other System Configurations and Tests 2. Position the grip on the load frame adapter and insert the pin. 3. Tighten the locknut using a spanner wrench. MTS Criterion 40 System Dual Workspace Test Setup This procedure provides the basic steps required to run a test on an MTS Criterion 44 or MTS Criterion 45 dual workspace system. Some steps and details may vary according to your individual test requirements.
Best Practices for Other System Configurations and Tests Warning: Applying power can result in sudden crosshead motion. A moving crosshead can injure anyone in its path. Always clear the crosshead area before applying power. Dual Workspace Crush Zones 1. Turn on power to the system. The main power switch is located on the right side of the frame base. Select position I to turn the power on to the load frame and the controller. When the power is on, the displays on the frame control panel illuminate.
Best Practices for Other System Configurations and Tests Upper and Lower Workspace Selection Buttons 5. Enable the handset by pressing the Enable Handset button on the handset, so you have control of the system while working on the frame. 6. Expand the crosshead limits and move the crosshead so you have enough space in which to install the fixturing and specimen. 7. Attach the appropriate load cell cables for the workspace you will be using.
