  • Page 14: General Safety Practices

    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.
  • Page 15 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.
  • Page 16 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.
  • Page 17 Safety 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.

    Safety 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.

    Key Concepts on what you need to do. For instance, when you have completed preparation of your station, you minimize the Station Manager application. Then you launch MPX, select a test, and start the first test run of the test. When the test run is complete, you minimize MPX, and maximize the Station Manager application to load another specimen.
  • Page 45 Key Concepts Station File Types File Type Description MTS FlexTest A FlexTest project is a collection of files related to the station Project Files configuration. When you open a configuration, it opens in the context of its parent project. Files associated with configurations, such as sensor calibration files and parameter sets, are linked to configurations within the project directory.

Closed-loop control is a basic servomechanism concept of controlling a test, in which a controlling element controls a controlled element. Closed Loop Control Concept Item Description Feedback...
  • Page 49 Key Concepts Basic Closed-Loop Control in MTS Landmark Systems 1. You input a compressive command by adjusting the Manual Command slider control in the Station Manager application. 2. The Station Manager application (program source) instructs the digital controller to generate a signal that represents the direction and amount of force the actuator needs to apply to the specimen to accommodate your command.

  • Page 50: Understanding Control Channels And Control Modes

    Key Concepts Understanding Control Channels and Control Modes Control Channel (For example, Actuator) Control channels command actuator movement by providing a valve driver signal to the servovalve. The servovalve causes the actuator to move, which applies forces to the specimen. Control Modes (For example, Force or Displacement) A control channel includes one or more control modes.

  • Page 51: Sensor Limits

    Key Concepts Sensor Limits One type of detector is a limit detector for sensor input signals. Each sensor can have a high and a low limit which you can enable separately. When a sensor exceeds (or trips) its upper or lower limit, the selected detector action occurs.

  • Page 52: Positioning The Crosshead To Install The Specimen

    Key Concepts For load frames with base mounted actuators (as used by the typical system in this manual), the load train consists of all the components between the actuator’s piston rod (the component that moves up and down) and the crosshead. This typically includes the lower grip, the specimen, the upper grip, and the force sensor (load cell), as shown.

  • Page 53: Positioning The Actuator To Install The Specimen

    Key Concepts Positioning the Actuator to Install the Specimen You typically position the actuator every time you install a specimen. On the typical system used as an example in this manual, you use the Manual Command panel in the Station Manager application to position the actuator.

Note: The Select Project window will not appear if you selected Project1 as the default project when you installed the MTS TestSuite application.

  • Page 60: Verify Calibration Files

    Running the Example HCF Test 6. Ensure that the HSM (hydraulic service manifold) is off. Turning the HSM off removes power from the actuator so that it cannot move unexpectedly during load frame inspection or specimen installation. Note: It is acceptable to leave the pump (HPU) on, as it may be needed for other stations and also leaves power to the hydraulic grips for specimen installation.

    Running the Example HCF Test 8. Release the lower grip and remove the specimen. Using a tool that keeps your hands clear of the actuator, grasp the specimen and release the lower grip. That completes this Example test. If Appropriate, Remove the Broken Specimen Use this procedure only if the specimen is broken at the conclusion of the test run.

    Running the Example HCF Test “If Necessary, Recover from a Tripped Force Limit” on page 107 “If Necessary, Recover from a Tripped Displacement Limit” on page 110 If Necessary, Recover from a Tripped Force Limit There are a number of possible causes for a tripped force limit. For example: Clamping a grip may result in a force spike higher than expected.

Navigate to Station Manager >Display > Station Setup > Channels > Landmark 1 (or other depending on your configuration) > Force > Limits. B. Enter -50 N in the Lower Limit text box and ensure that Interlock is selected for the Action.
  • Page 111 Running the Example HCF Test The actuator may have retracted below the lower displacement limit during specimen installation. The actuator may have retracted when the specimen broke at the conclusion of the test. Your test limits may have been insufficient for the test. Rather than cover all possibilities, this section addresses the first case only.

In the Station Manager application main window, click the Reset/Override button three times to override the Interlock for 21 seconds, and then power up the HPU and HSM. Warning: Do not move the control slider until the crush zone is clear, and you can monitor actuator movement.
