QTest Materials Test Systems Preface 7

Conventions

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

Hazard conventions Hazard notices are embedded in this manual and 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 manual included with your system.

Danger notices Danger notices indicate the presence of a hazard which will cause severe personal injury, death, or substantial property damage if the danger is ignored. For example:

High intensity light and dangerous radiation are emitted by class 3B

lasers.

Viewing a class 3b laser directly or viewing it using optical instruments

will cause immediate and severe injury.

Avoid eye or skin exposure to the laser beam. Ensure that all power to the laser is off before attempting any maintenance, service, or adjustment procedure.

Warning notices Warning notices indicate the presence of a hazard which can cause severe personal injury, death, or substantial property damage if the warning is ignored. For example:

Hazardous fumes can accumulate in the test chamber as a result of

testing.

Breathing hazardous fumes can cause nausea, fainting, or death.

Ensure the chamber is properly ventilated before you open the chamber door or put your head or hands into the chamber. To do this, ensure the temperature controller is off and allow sufficient time for the ventilation system to completely exchange the atmosphere within the chamber.

Description

QTest Materials Test Systems Introduction 15

System performance The PC that you have chosen is an integral part of the system. It runs the MTS software that provides full machine control, data acquisition and management, and advanced data analysis and presentation. MTS has minimized the amount of custom electronics in your system, making it flexible and reliable as possible. This is done by connecting the frame (through the port on the controller designated for the computer) and the computer ECP port with an IEEE 1284 cable.

The basic load frame has a rectangular shape and includes a base unit, two vertical columns, and a fixed upper transverse member. A base adapter is attached to the top section of the base unit. A moving crosshead, guided by vertical rods, is located between the base and upper transverse member. The moving crosshead is driven by precision ballscrew(s) on the load frame. The crosshead is coupled to the ballscrew(s) with high strength, precision ball nuts and actually rides on the ball bearings that are very efficient in minimizing friction and wear.

The screws are driven by a series of pulleys and belts coupled by a direct drive system, which in turn is driven by a low inertia brushless servo motor. The motor is equipped with resolver feedback for precise velocity and position control.

The QTest Elite is controlled by MTS’s latest high-precision electronics – (see the folowing figure). The controller is separate from the machine which assists in troubleshooting and repair. It is contained in a smaller rectangular box with cables for connection to the load frame.

Installation

This section is a guide to help you install your MTS QTest Elite Material Testing Workstation.

Note If the machine is to be shipped from one site to another, it must be transported by AIR RIDE VAN.

Important Unless otherwise specified, it is your responsibility to off-

load and move the equipment to the final location on your

premises. This includes insurance and safety

responsibilities.

Initial off-loading andmoving of QTest

System

Before moving the machine from the receiving area to its final location, be sure to check the dimensions of all doors and passages through which the machine will travel. Please refer to the specifications section of this manual for system dimensions.

If the machine is being relocated for installation at a different site, all load cells, extensometers, and additional accessories should be removed and packed separately.

Location andventilation

The control box can be placed on the floor next to or behind a floor-standing machine, or beneath a tabletop machine. The box should be positioned so that the circuit breaker located on the back panel is accessible.

Ventilation holes are present in the top and bottom of the control enclosure. Do not block either of these openings during use.

For comfortable working conditions and proper equipment operation, heat dis-sipation of the equipment must be considered in providing adequate heating or air conditioning in the laboratory area. Heat dissipation may be approximated by summing the heat losses going into a room (1 kVA is equivalent to 860 kcal/hr [3400 Btu/hr] ) and the gains from other sources such as furnaces and personnel.

QTest Materials Test SystemsInstallation22

Moving the QTestframes

Very heavy equipment! Movement and positioning should be performed by qualified personnel only. Machine weight varies. Please review weight specifications. The pallet, packaging, and accessories add to make the total palletized weight as much as 680 kg (1,500 lbs.). If you have any questions, please contact MTS at 1-800-328-2255.

Moving the palletizedmachine

Pallet jacks rated at 900 kg (2,000 lbs.) or proper fork trucks can be used.

The machine should not be moved by its pallet without the metal stapping firmly in place. Due to the height of the machine and the configuration of the pallet, caution should be used to prevent tip-over type accidents while transporting the palletized machine.

If you choose to move the palletized frame by lifting the machine instead of moving it by pallet, you should use only the correct lifting methods listed below.

• By padded forks under the crosshead.

• By padded strapping around the crosshead (to prevent crosshead and/or label damage).

The load frame may be irreparably damaged if lifted by the incorrect lifting methods listed below.

• DO NOT LIFT by the top plate that joins the ends of the ball screws and extrusions.

• DO NOT LIFT machine by the extrusions (the weight of the machine will damage the extrusions).

• DO NOT LIFT by the ball screws (under the bellows).

• DO NOT LIFT by the base unless the frame is resting on a pallet.

Travel limit switches (Physical limits)

The limit switches are located on the crosshead. They are normally closed (designated by a green light – fail safe mode) and are activated when the adjustable limit comes in contact with the limit switch. The limit can be positioned anywhere along the extrusion to prevent the crosshead from traveling beyond that point.

Always adjust the limits whenever you change grips or fixtures.

Damage to equipment or personal injury may result.

When a physical limit is reached there are three ways to get the crosshead moving again:

• Utilize the crosshead capabilities of your software (virtual handset). Move the crosshead away from the limit until the switch closes and the crosshead can move in both directions again. See the TestWorks 4 software manual for further details.

• Manually move the adjustable limit along the guide column away from the crosshead until the limit switch is no longer active.

• Use the manual handset control to move the crosshead until the limit switch is no longer active.
