Preface

Before You Begin

Safety first!

Other MTS manuals

Before you attempt to use your MTS product or system, read and understand the Safety manual and any other safety information provided with your system. Improper installation, operation, or maintenance of MTS equipment in your test facility can result in hazardous conditions that can cause severe personal injury or death and damage to your equipment and specimen. Again, read and understand the safety information provided with your system before you continue. It is very important that you remain aware of hazards that apply to your system.

In addition to this manual, you may receive additional MTS manuals in paper or electronic form.

If you have purchased a test system, it may include an MTS System Documentation CD. This CD contains an electronic copy of the MTS manuals that pertain to your test system, including hydraulic and mechanical component manuals, assembly drawings and parts lists, and operation and preventive maintenance manuals. Controller and application software manuals are typically included on the software CD distribution disc(s).

Electronic manual conventions

The following paragraphs describe some of the conventions that are used in your MTS manuals.

As necessary, hazard notices may be embedded in this manual. These notices contain safety information that is specific to the task to be performed. Hazard notices immediately precede the step or procedure that may lead to an associated hazard. Read all hazard notices carefully and follow the directions that are given. Three different levels of hazard notices may appear in your manuals. Following are examples of all three levels.

Note For general safety information, see the safety information provided with your system.

DANGER

Danger notices indicate the presence of a hazard with a high level of risk which, if ignored, will result in death, severe personal injury, or substantial property damage.

WARNING

Warning notices indicate the presence of a hazard with a medium level of risk which, if ignored, can result in death, severe personal injury, or substantial property damage.

CAUTION

Caution notices indicate the presence of a hazard with a low level of risk which, if ignored, could cause moderate or minor personal injury, equipment damage, or endanger test integrity.

Notes provide additional information about operating your system or highlight easily overlooked items. For example:

Note Resources that are put back on the hardware lists show up at the end of the list.

The first occurrence of special terms is shown in italics.

Illustrations appear in this manual to clarify text. It is important for you to be aware that these illustrations are examples only and do not necessarily represent your actual system configuration, test application, or software.

Rate control

Series 685 Hydraulic Grip Supplies are designed to provide the hydraulic pressure and grip control for specimen grips. All of the grip supplies include the following features:

•Hydraulic flow control determines how fast the grips operate.

•Each grip has an independent pressure control valve. Each model has a different adjustment range.

•Each of the two grips has an independent grip/release control.

The Model 685.10 Hydraulic Grip Supply includes a self-contained hydraulic system. Only electrical power is needed for continuous operation. The hydraulic pressure can be adjusted between 7 MPa (1000 psi) and adjusted up to the rated output 70 MPa (10,000 psi).

The Model 685.22 Hydraulic Grip Supply includes a self-contained hydraulic system. Only electrical power is needed for continuous operation. The hydraulic pressure can be adjusted between 0.7 and 20.7 MPa (100 and 3000 psi).

The Model 685.60 Hydraulic Grip Supply uses the hydraulic power unit (HPU) installed in your lab. The grip supply is factory rated for 45 MPa (6500 psi) or 68 MPa (10,000 psi). The output pressure can be adjusted up to the rated output.

The Model 685.10 and Model 685.22 Hydraulic Grip Supplies have a selfcontained hydraulic system. The Model 685.60 Hydraulic Grip Supply gets its hydraulic pressure from the hydraulic power unit in the lab.

The self-contained units include a reservoir for the hydraulic fluid and a motor that drives a pump. The pump draws the hydraulic fluid from the reservoir through a strain filter. The hydraulic fluid is pumped to the pressure manifold where the pump pressure is regulated. When the hydraulic fluid is returned to the reservoir, it is run through a cooler and a 10-micron filter.

The supply manifold includes two pressure reducing valves and a pressure gage. One of the pressure reducing valves establishes the output pressure of the pump (each model is set to a different pressure). The other is used as a relief valve that is set 1.7 MPa (250 psi) higher than the pump’s output pressure. In the event the output pressure exceeds the relief valve setting, the excess hydraulic pressure is shunted to the return line. The output is sent to the control manifold.

The control manifold outputs the hydraulic control to the grips. The control manifold includes all of the front panel controls. All three models use the same front panel controls.

The Model 685.10 and Model 685.60 Hydraulic Grip Supplies include two oil-to- oil hydraulic intensifiers. These devices multiply the input pressure by a factor of four to obtain a higher output pressure.They are located on the control manifold.

The Rate control is a needle valve that restricts the hydraulic flow. This adjustment determines how fast the grips clamp and unclamp.

Important The rate setting will be different for all grip sizes. You should be sure to change this setting whenever you change grip sizes.
