  • Page 13: Preface

    Preface Preface Before You Begin Safety first! Before you use your MTS product or system, read and understand the safety information provided with your system. Improper installation, operation, or maintenance can result in hazardous conditions that can cause severe personal injury or death, or damage to your equipment and specimen. Again, read and understand the safety information provided with your system before you continue.

  • Page 14: Other Special Text Conventions

    Preface Other special text conventions Important: Important notices provide information about your system that is essential to its proper function. While not safety-related, if the important information is ignored, test results may not be reliable, or your system may not operate properly. Note: Notes provide additional information about operating your system or highlight easily overlooked information.

  • Page 16: 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 17: Safety Practices Before Operating The System

    Safety 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.

  • Page 18: Be Aware Of Component Movement With Hydraulics Off

    Safety 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.

  • Page 19: Know Compressed Gas Hazards

    Safety 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.

  • Page 20: Practice Good Housekeeping

    Safety 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.

  • Page 21: Do Not Disable Safety Devices

    Safety 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.

  • Page 22: Safety Practices While Operating The System

    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.

  • Page 23: Know System Limits

    Safety 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.

  • Page 24: Do Not Use Rf Transmitters

    Maintenance cylinder. To check the approximate piston location, note the warm-to-hot transition point on the accumulator cylinder wall during operation. If the piston is near the charging stem end, the accumulator may need charging. If the piston is at the other end, the accumulator may have an excess charge, or more likely an excessive amount of hydraulic fluid has collected in the gas chamber.

  • Page 112: Decrease Pressure

    Maintenance Warning: Accumulators have specific pressure ratings. If the precharge pressure is too high, the accumulator can bottom out causing the release of metal particles into the hydraulic fluid. Charging accumulators above their rated level can damage system equipment. Do not charge accumulators to pressures above their rated level. Charge accumulators below their rated fatigue pressure of 21 MPa (3000 psi) for the Model 111.11B and 22 MPa (3200 psi) for the Model 111.12C.

    Maintenance Rapid flow rates with pressure differentials of more than 2.1 MPa (300 psi) across the input check valve can damage the valve seal(s). Avoid rapid and extreme pressure transitions. Do not allow rapid flow rates. Open the regulator shut-off valve only far enough to permit a gradual transfer of gas.

    Contaminated hydraulic fluid can cause premature wear of the hydraulic components in your system. Do not mix different brands of hydraulic fluid. MTS Systems Corporation recommends using Mobil DTE-25 or Shell Tellus 46 AW hydraulic fluid. The filter element should be replaced whenever: The indicator on the top of the filter housing is in the bypass position, which indicates a dirty filter condition.

  • Page 119 Maintenance Do not perform the following procedure without clearing the path of motion of the actuator. Ensure that all personnel, specimen/structures, and tools are away from the path of motion of the actuator (crush zone). 1. Exercise the actuator. The actuator should be exercised to warm it up. Electrical and mechanical adjustments are more repeatable after the actuator is warmed up.

    Maintenance Performing Sensor Calibration Calibration intervals depend on system requirements and are typically performed during scheduled maintenance by MTS trained personnel. Contact MTS for additional information on sensor calibration. Sensors can include LVDTs, load cells, and extensometers. All sensors require calibration to ensure that their outputs accurately represent the physical condition they sense (that is, force or displacement).

  • Page 123: Decommissioning

    Decommissioning Decommissioning Decommission the System The decommissioning process is performed when the system is going to be moved or taken out of service. Dis-assembly is required when performing either of these tasks. 1. Remove the specimen and fixtures. Large grips should be removed if the load frame is going to be tipped over.
  • Page 124 Decommissioning Warning: Residual hydraulic pressure can produce a high-pressure spray. You could be cut by this spray or hydraulic fluid could be forced into your skin. Do not continue with this procedure unless the system has been isolated from hydraulic pressure for at least 20 minutes.
