Page 22: Safety Practices Before System Operation
If you have system related responsibilities (that is, if you are an operator, service engineer, or maintenance person), you should study safety information 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 23 Locate and read Find, read, and follow the hazard placard instructions located on the equipment. hazard placards/labels These placards are placed strategically on the equipment to call attention to areas such as known crush points and electrical voltage hazards. Locate Lockout/tautog Know where the lockout/tagout point is for all of the supply energies associated points with your system.
- Page 24 Keep bystanders Keep bystanders at a safe distance from all equipment. Never allow bystanders to safely away 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.
- Page 25 • 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.

You will need the following equipment to unpack the load frame: • Lifting slings—not chains—to lift the load frame from its pallet •... - Page 35 270 N•m (200 lbf•ft) 311.51 920 N•m (680 lbf•ft) Contact MTS Systems Corporation for torque specifications for the Model 311.61 and Model 311.71 Load Frames. 4. Tip the load frame upright. A. Attach the chains to the lifting eyebolts. Move the crane/forklift to keep the chains as straight as possible.
- Page 36 Unpacking the Load Frame Slowly raise the load frame to its upright position. As the unit rises, keep moving the crane to keep the chains as straight as possible. Crane Travel 30° Maximum 30° maximum when connecting both eye bolts to a single point. When the load frame is upright, raise it slightly to clear the shipping pallet.

Page 38: Connecting Cables
Connecting Cables Connecting Cables Your controller manual should have cabling information about the connections described in this section. Most controller manuals provide the signal pinouts of the connector and assembly numbers for standard MTS cables. Note Many of the cables are connected to optional equipment. The following procedure shows the most common connections. -
Page 39: Connecting Hydraulics
Connecting Hydraulics Connecting Hydraulics The procedure describes how to connect the load frame to the hydraulic power source. The load frame can be connected directly to the hydraulic power unit (also called HPU), to hydraulic plumbing in the workplace, or through a hydraulic service manifold (HSM). -
Page 40: Removing The Shipping Collars
Removing the Shipping Collars Removing the Shipping Collars When the load frame is shipped, the crosshead is clamped in position with shipping collars.

Page 44: Installing A Specimen
Installing a Specimen Installing a Specimen The procedure to install a specimen varies due to the variety of test fixtures, grips, and the type of specimen being installed. This section should be considered a guideline. You need to modify this procedure to suit your equipment. Prerequisite You must have the necessary grips and/or fixturing installed. - Page 45 Installing a Specimen Note Always lower the crosshead to where you want it. The pressure remaining in the lift cylinders after raising the crosshead can slightly shift its alignment. Lowering the crosshead to its final position removes this pressure and improves alignment. Use the Crosshead Lift/Lock Controls to move the crosshead to a point where you can install the specimen (or specimen fixture) into the upper grip or fixture without obstruction.

Page 61: Aligning The Force Transducer
Aligning the Force Transducer Aligning the Force Transducer This section describes how to align a force transducer with the load frame actuator. WARNING Alignment takes place in a crush zone with hydraulic pressure on. Hands can be crushed and equipment can be damaged equipment when hydraulics are turned on. - Page 62 Aligning the Force Transducer If your load frame has an anti-rotate actuator, unscrew the four cap screws that attach the anti-rotate plate to the bottom of the piston. The anti-rotate plate is at one end of the actuator. 2. Check the alignment. Check the alignment between the force transducer and the actuator.
- Page 63 Aligning the Force Transducer Slowly turn the actuator to rotate the indicator 360° around the force transducer. Stop frequently to take indicator readings. Keep your hands off the actuator and indicator when taking the readings. Compute the total indicator runout (TIR). Take the maximum dial indicator reading and subtract the minimum dial indicator reading.
