Safety
General Safety Practices
This section provides information about safety issues that pertain to electrodynamic systems in general.
These issues include statements to the intended use and foreseeable misuse of the system, the hazard zone,
definition for the graphical hazard labeling that is affixed to your product, and other (more general) safety
information that relates to the high-performance characteristics of MTS electrodynamic systems.
MTS test systems are designed to generate motions and forces and impart these motions and forces into a
test specimen.
When you prepare to operate the system and during system operation, ensure the following:
• Do not use or allow personnel to operate the system who are not experienced, trained, or educated in the
inherent dangers associated with high-performance electrodynamic systems and who are not experienced,
trained, or educated with regard to the intended operation as it applies to this test system.
• Do not disable safety components or features (including limit detectors, light curtains, or proximity
switches/detectors).
• Do not attempt to operate the system without appropriate personal safety gear (for example, hearing,
hand, and eye protection).
• Do not apply energy levels that exceed the maximum energies and velocities for the system design. Refer
to the system specifications.
• Whenever possible, use tongs or a similar device to handle specimens during specimen installation.
• Do not test a specimen that exceeds the minimum (if applicable) or maximum allowable mass. Refer to
the system specifications.
• Do not use specimens that are combustible, flammable, pressurized, or explosive.
• Do not modify the system or replace system components using parts that are not MTS component parts
or effect repairs using parts or components that are not manufactured to MTS specifications.
• Do not operate the system in an explosive atmosphere.
• Do not use the system in a test area where uncontrolled access to the test system is allowed when the
system is in operation.
• Use the low power lock when working in the test space with power on.
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. In addition, you should gain an understanding
of system functions by studying the other manuals supplied with your test system. Contact MTS for information
about the content and dates of training classes that are offered.
It is very important that you study the following safety information to ensure that your facility procedures and
the system’s operating environment do not contribute to or result in a hazardous situation. Remember, you
cannot eliminate all the hazards associated with this system, so you must learn and remain aware of the
hazards that apply to your system at all times. Use these safety guidelines to help learn and identify hazards
so that you can establish appropriate training and operating procedures and acquire appropriate safety
equipment (such as gloves, goggles, and hearing protection).
Each test system operates within a unique environment which includes the following known variables:
14 MTS Acumen™ Electrodynamic Test System
• Facility variables (facility variables include the structure, atmosphere, and utilities)
• Unauthorized customer modifications to the equipment
• Operator experience and specialization
• Test specimens
Because of these variables (and the possibility of others), your system can operate under unforeseen
circumstances that can result in an operating environment with unknown hazards.
Improper installation, operation, or maintenance of your system can result in hazardous conditions that can
cause death, personal injury, or damage to the equipment or to the specimen. Common sense and a thorough
knowledge of the system’s operating capabilities can help to determine an appropriate and safe approach to
its operation.
Safety Practices Before System Operation
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.
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.
Locate and read hazard placards/labels
Find, read, and follow the hazard placard instructions located on the equipment. These placards are placed
strategically on the equipment to call attention to areas such as known crush points and electrical voltage
hazards.
Locate lockout/tagout points
Know where the lockout/tagout point is for all of the supply energies associated with your system. This includes
the hydraulic, pneumatic, electric, and water supplies (as appropriate) for your system to ensure that the
system is isolated from these energies when required.
Know facility safe procedures
Most facilities have internal procedures and rules regarding safe practices within the facility. Be aware of
these safe practices and incorporate them into your daily operation of the system.
Locate Emergency Stop buttons
Know the location of all the system Emergency Stop buttons so that you can stop the system quickly in an
emergency. Ensure that an Emergency Stop button is located within 2 meters (6 feet) of the operator at all
times.
Know controls
Before you operate the system for the first time, make a trial run through the operating procedures with the
power off. Locate all hardware and software controls and know what their functions are and what adjustments
MTS Acumen™ Electrodynamic Test System 15
Safety
they require. If any control function or operating adjustment is not clear, review the applicable information
until you understand it thoroughly.
Have first aid available
Accidents can happen even when you are careful. Arrange your operator schedules so that a properly trained
person is always close by to render first aid. In addition, ensure that local emergency contact information is
posted clearly and in sight of the system operator.
Know potential crush and pinch points
Be aware of potential crush and pinch points on your system and keep personnel and equipment clear of
these areas.
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. Observe the same precautions as those given for any other high-voltage machinery.
Keep bystanders safely away
Keep bystanders at a safe distance from all equipment. Never allow bystanders to 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. Remove loose clothing or jewelry and restrain long hair.
Remove flammable fluids
Remove flammable fluids from their containers or from components before you install the container or
component. If desired, you can replace the flammable fluid with a non-flammable fluid to maintain the proper
proportion of weight and balance.
Check bolt ratings and torques
To ensure a reliable product, fasteners (such as bolts and tie rods) used in MTS-manufactured systems are
torqued to specific requirements. If a fastener is loosened or the configuration of a component within the
system is modified, refer to the system and component assembly drawings (located on the System
Documentation CD) to determine the correct fastener, fastener rating, and torque. Overtorquing or undertorquing
a fastener can create a hazardous situation due to the high forces and pressures present in MTS test systems.
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.
Practice good housekeeping
Keep the floors in the work area clean. Do not leave tools, fixtures, or other items not specific to the test lying
about on the floor, system, or decking.
16 MTS Acumen™ Electrodynamic Test System
Safety
Protect hoses and cables
Protect electrical cables from excessive temperatures that can cause the cables to harden and eventually
fail. Ensure that all cables have appropriate strain relief devices installed at the cable and near the connector
plug. Do not use the connector plug as a strain relief.
Protect all system hoses and cables from sharp or abrasive objects that can cause the hose or cable to fail.
Never walk on hoses or cables or move heavy objects over them.
When removing hydraulic hoses for equipment repair or changing testing components (for example, hydraulic
grips), make sure to cap the hose ends to avoid spilling hydraulic fluid.
Record changes
If you change any operating procedure, write the change and the date of the change in the appropriate manual.
Provide test area guards
Use protective guards such as cages, enclosures, and special laboratory layouts when you work with hazardous
test specimens (for example, brittle or fragmenting materials or materials that are internally pressurized).
Do not disable safety devices
Your system might 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 can 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. Undersized or oversized fuses can result in cables that overheat and fuses that explode.
Either instance creates a fire hazard.
Provide adequate lighting
Ensure adequate lighting to minimize the chance of operation errors, equipment damage, and personal injury.
You need to see what you are doing.
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. For
example ladders or scaffolding might be required to reach load cell connectors on tall load units.
Ensure equipment is secure
Make sure the equipment is secure or provide vibration isolation. Some testing can be performed at resonant
frequencies that might cause the equipment to vibrate and move during testing.
Safety Practices While the System Is in Operation
Wear appropriate personal protection
Wear eye protection when you work with 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. Some systems can create sound pressure levels that exceed 70 dbA during operation.
MTS Acumen™ Electrodynamic Test System 17
Safety
Wear appropriate personal protection equipment (gloves, boots, suits, respirators) whenever you work with
fluids, chemicals, or powders that can irritate or harm the skin, respiratory system, or eyes.
Provide test area enclosure
Use protective enclosures such as cages, guards, and special laboratory layouts when you work with hazardous
test specimens (for example, brittle or fragmenting materials or materials that are internally pressurized).
MTS can provide an optional test area enclosure that properly fits the load frame. If a test area enclosure is
not purchased from MTS, it is the customer's responsibility to provide proper protective devices to ensure
operator safety.
Specimen temperature changes
During cyclic testing, the specimen temperature can become hot enough to cause burns. Wear personal
protection equipment (gloves) when handling specimens.
Handle chemicals safely
Whenever you use or handle chemicals (for example, cleaning fluids, batteries, contaminated parts, electrical
fluids, and maintenance waste), refer to the appropriate MSDS documentation for that material and determine
the appropriate measures and equipment required to handle and use the chemical safely. Ensure that the
chemical is disposed of appropriately.
Know system interlocks
Interlock devices should always be used and properly adjusted. Interlock devices are designed to minimize
the chance of accidental damage to the test specimen or the equipment. Test all interlock devices for proper
operation immediately before a test. Do not disable or bypass any interlock devices, as doing so could allow
forces to be applied regardless of the true interlock condition. The Reset/Override button is a software function
that can be used to temporarily override an interlock while attempting to start power and gain control of the
system.
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.
Do not disturb sensors
Do not bump, wiggle, adjust, disconnect, or otherwise disturb a sensor (such as a load cell, accelerometer,
or extensometer) or its connecting cable when power is applied.
Ensure secure cables
Do not change any cable connections when electrical power is applied. If you attempt to change a cable
connection while the system is in operation, an open control loop condition can result. An open control loop
condition can cause a rapid, unexpected system response which can result in severe personal injury, death,
or damage to equipment. Also, ensure that all cables are connected after you make any changes in the system
configuration.
Stay alert
Avoid long periods of work without adequate rest. In addition, avoid long periods of repetitious, unvarying, or
monotonous work because these conditions can contribute to accidents and hazardous situations. If you are
too familiar with the work environment, it is easy to overlook potential hazards that exist in that environment.
18 MTS Acumen™ Electrodynamic Test System
Safety
Contain small leaks
Do not use your fingers or hands to stop small leaks in pneumatic hoses. Substantial pressures can build up,
especially if the hole is small. These high pressures can cause the gas to penetrate your skin, causing painful
and dangerously infected wounds. Turn off the pneumatic supply and allow the pneumatic pressure to dissipate
before you remove and replace the hose or any pressurized component.
Stay clear of moving equipment/avoid crush points
Stay clear of mechanical linkages, connecting cables, and hoses that move because you can get pinched,
crushed, tangled, or dragged along with the equipment. High forces generated by the system can pinch, cut,
or crush anything in the path of the equipment and cause serious injury. Stay clear of any potential crush
points. Most test systems can produce sudden, high-force motion. Never assume that your reactions are fast
enough to allow you to escape injury when a system fails.
Know the causes of unexpected actuator motions
The high force and velocity capabilities of MTS actuators can be destructive and dangerous (especially if
actuator motion is unexpected). The most likely causes of unexpected actuator response are operator error
and equipment failure due to damage or abuse (such as broken, cut, or crushed cables and hoses; shorted
wires; overstressed feedback devices; and damaged components within the servocontrol loop). Eliminate
any condition that could cause unexpected actuator motion.
Do not use RF transmitters
Keep radio frequency (RF) transmitters away from the workstation computers, remote terminals, and electronics
consoles. Intense RF fields can cause erratic operation of the more sensitive circuits in the system.
Crush Zone
A crush zone exists between the T-slot base and crosshead which is highlighted in red in the following figure.
Keep clear of this area when the actuator is in motion. Press the Emergency Stop button on the frame-mounted
control to shut off power to the motor and stop actuator motion.
MTS Acumen™ Electrodynamic Test System 19
Safety

Warning:
Applying power can result in sudden actuator motion.
A moving actuator can injure anyone in its path.
Always clear the actuator area before applying power.
20 MTS Acumen™ Electrodynamic Test System
Crosshead Emergency Operation
The load frame has a manual lift actuation feature. It consists of manual method to turn the lift drive system
if the load frame or lift system lose power. In such an event, an external 10mm hex bolt can be accessed
from the underside of the crosshead. A 10mm socket wrench is required to actuate the lift system. The label
shows which direction to turn the wrench to either raise or lower the crosshead.
There are several scenarios in which the manual lift actuation system would be useful.
• In the event of a loss of facility power, a specimen can be removed from the system.
• If there is a system malfunction that prevents running the lifts via typical electrical means, the manual
approach can be used to remove specimens.
• In the event of a user, tool, fixture or specimen becoming entrapped in the load frame, and power is
removed either via E-stop activation, power switch activation or power cord removal, the entrapped person
or tool can be removed using the manual mechanism.
The following figure shows a close-up of the system load cell mounted on the actuator and a red arrow pointing
to the location of the hex bolt.
Safety
The manual locks must be unlocked for the system to move the crosshead.

Installation
Frame Location and Ventilation
To ensure proper ventilation, locate the load frame approximately 300 mm (12 inches) from adjacent walls
and equipment. Allow approximately 1 m (3 feet) behind the equipment for service access. Do not block the
vent holes on the sides or back of the frame.
For comfortable working conditions and proper equipment operation, heat dissipation of the equipment must
be considered in providing adequate heating or air conditioning in the laboratory area. Heat dissipation can
be approximated by summing the heat losses going into a room (1 kVA is equivalent to 860 kcal/hr [3,400
Btu/hr]) and the gains from other sources such as furnaces and personnel.
Environmental Requirements
All MTS Acumen load frames are intended for indoor use only. This indoor environment must conform to the
following environmental specifications.

MTS Acumen™ Electrodynamic Test System 35
Installation
Note:
Local electrical codes supercede any information found here.
Customers should use the power cord kit supplied by MTS for connecting electrical power and ground to the
load frame. Use of power cords with inadequate ratings that are not equivalent to the power cord provided
with your MTS Acumen product could cause a dangerous situation.
Note:
Electrical connections must be made by qualified personnel and is their responsibility for using the
proper power disconnect that conforms to local codes and regulations when connecting the machine
to the buildings main power.
Redundant Protective Earth Ground Connection
A redundant protective earth ground connection is required. MTS Acumen Systems contain high-power drive
systems which create high ground-leakage current; therefore the MTS Acumen load frame requires a permanent
protective earth ground connection in addition to the ground in the AC mains plug/socket connection. An
additional protective earth conductor of appropriate wire gage is supplied with the power cord for this product. At
the load frame, this protective earth conductor must be connected to the grounding post near the AC mains
input of the MTS Acumen load frame. Facility-side connection of the protective earth conductor must be done
in accordance with local electrical codes. If a supplemental ground is not available, MTS offers an optional
permanently wired hard cord kit.
The photos below show the Mains Power Cable with the Supplemental Ground connection.
36 MTS Acumen™ Electrodynamic Test System
Electrical Disconnect
Ensure that there is access and adequate room behind the frame to allow electrical disconnection of the
power cord. Disconnect the power cord before cleaning or inspecting any part of the test frame.
When the hard cord kit option is used, the customer is responsible for providing an electrical power disconnect
that is easy to operate and easy to reach. It must also meet IEC 60947-1 and IEC 60947-3 standards.
Recommended circuit breakers would be ones that are of the thermal-magnetic type with characteristics
suitable for large inductive loads (D-type trip characteristic). If fuses are used, it is recommended that they
are of the time-delay type with dual elements. These recommendations should be followed to avoid nuisance
tripping.
Installing Cables
Exercise care when connecting cables. Ensure that you use the correct cables and that all connections are
secure. When you are finished, double-check to ensure that all components are connected properly.
To maintain EMC compliance and help ensure optimal performance, MTS recommends ordering all system
cables from MTS. Cables should be installed so that they are protected from conditions that could damage
the cable.
Installation
Caution:
There is dangerous voltage inside the machine.
Connecting cables with power applied can cause damage to the equipment.
Ensure that the power is turned off before connecting cables.

Grounding Information
All equipment related to the load frame should be connected to the same electrical circuit if possible. If the
computer, monitor, or other peripherals are connected to a different electrical circuit (for example, the load
frame is connected to 208 VAC power but the computer and monitor are connected to 120 VAC power), make
sure there is no voltage difference between the two different grounds. If voltage is present, damage could
occur to the electronics in the machine, the computer and monitor, or the peripherals being used. This must
be resolved before turning on the equipment.
Where electrical power is of poor quality (noise spikes, poorly regulated, and so forth) or the ground system
in the facility contains electrical noise, attach a 4 AWG wire directly to a good earth ground point, such as a
2 m (6 ft) copper grounding rod driven at least 2 m (6 ft) into the ground. Grounding must conform to local
electrical codes.

devices. The following paragraphs describe crush zones and precautions to take while working around crush
zones.
Locations
A crush zone exists between the T-slot base and crosshead.
MTS Acumen™ Electrodynamic Test System 55
Operation
Precautions
Keep clear of any mechanical linkage that moves within a closed area. If the linkage should move (when the
system starts or due to mechanical failure), very high forces can be present that could pinch, cut, or crush
anything in the path of linkage movement.
Never allow any part of your body to enter the path of machine movement or to touch moving machinery,
linkages, hoses, cables, specimens, and so forth. These present serious crush points or pinch points.
Fixture Mounting
MTS offers a wide variety of fixtures. Mounting these fixtures typically involves installing the fixture or load
cell onto a mounting (clevis pin) adapter and securing it with a mounting dowel (pin). To further secure a
fixture, some configurations also include locking collars.
56 MTS Acumen™ Electrodynamic Test System
Frame-Mounted Control
The frame-mounted control can be attached to the left or right side of the frame. It provides controls to help
you mount fixtures, and install specimens. The frame-mounted control also has an alphanumeric display and
illuminated icons to provide feedback.

Decommissioning
The decommissioning process is performed when the system is going to be moved or taken out of service.
Disassembly is required when performing either of these tasks.
To decommission the system:
1. Remove the specimen and fixtures. Large grips should be removed if the load frame could be tipped over.
2. Isolate the system from electrical power.
3. When the system electronics, control software, and the system PC are powered down, turn off the system’s
main electrical supply and disconnect all cables.
4. Disconnect all cables from the controller.
5. Cover the material testing machine with a dust cover, such as plastic foil. Allow for sufficient ventilation
or place a dehumidifier near the equipment.
6. Place the accessories and the instruction manual in a clean, dust-protected place, such as a tool cabinet.
Caution:
Electrical components and parts can contain hazardous chemicals and compounds.
Always refer to local codes that govern the disposal of potentially hazardous materials and
follow these codes for the proper handling and disposal of these materials.
You should follow internal safety policies for safe disposal of parts of the machine. Refer to
