General Safety Precautions
Materials testing systems are potentially hazardous.
Materials testing involves inherent hazards from high forces, rapid motions, and
stored energy. You must be aware of all moving and operating components in the
testing system that are potentially hazardous, particularly force actuators or a
moving crosshead.
Carefully read all relevant manuals and observe all Warnings and Cautions. The
term Warning is used where a hazard may lead to injury or death. The term Caution
is used where a hazard may lead to damage to equipment or to loss of data.
Instron products, to the best of its knowledge, comply with various national and
international safety standards, in as much as they apply to materials and structural
testing. We certify that our products comply with all relevant EU directives (CE
mark).
Because of the wide range of applications with which our instruments are used, and
over which we have no control, additional protection devices and operating
procedures may be necessary due to specific accident prevention regulations, safety
regulations, further EEA directives or locally valid regulations. The extent of our
delivery regarding protective devices is defined in your initial sales quotation. We
are thus free of liability in this respect.
At your request, we will gladly provide advice and quotations for additional safety
devices such as protective shielding, warning signs or methods of restricting access
to the equipment.
The following pages detail various general warnings that you must heed at all times
while using materials testing equipment. You will find more specific Warnings and
Cautions in the text whenever a potential hazard exists.
Your best safety precautions are to gain a thorough understanding of the equipment
by reading your instruction manuals and to always use good judgement.
It is our strong recommendation that you should carry out your own product safety
risk assessment.
Hazard - Press the Emergency Stop button whenever you consider that an unsafe
condition exists.
The Emergency Stop button removes hydraulic power or electrical drive from the testing
system and brings the hazardous elements of the system to a stop as quickly as possible. It
does not isolate the system from electrical power, other means are provided to disconnect
the electrical supply. Whenever you consider that safety may be compromised, stop the test
using the Emergency Stop button. Investigate and resolve the situation that caused the use of
the Emergency Stop button before you reset it.
Flying Debris Hazard - Make sure that test specimens are installed correctly in grips
or fixtures in order to eliminate stresses that can cause breakage of grip jaws or
fixture components.
Incorrect installation of test specimens creates stresses in grip jaws or fixture components
that can result in breakage of these components. The high energies involved can cause the
broken parts to be projected forcefully some distance from the test area. Install specimens in
the center of the grip jaws in line with the load path. Insert specimens into the jaws by at
least the amount recommended in your grip documentation. This amount can vary between
66% to 100% insertion depth; refer to supplied instructions for your specific grips. Use any
centering and alignment devices provided.
Hazard - Protect electrical cables from damage and inadvertent disconnection.
The loss of controlling and feedback signals that can result from a disconnected or damaged
cable causes an open loop condition that may drive the actuator or crosshead rapidly to its
extremes of motion. Protect all electrical cables, particularly transducer cables, from
damage. Never route cables across the floor without protection, nor suspend cables
overhead under excessive strain. Use padding to avoid chafing where cables are routed
around corners or through wall openings.
High/Low Temperature Hazard - Wear protective clothing when handling equipment
at extremes of temperature.
Materials testing is often carried out at non-ambient temperatures using ovens, furnaces or
cryogenic chambers. Extreme temperature means an operating temperature exceeding 60 °C
(140 °F) or below 0 °C (32 °F). You must use protective clothing, such as gloves, when
handling equipment at these temperatures. Display a warning notice concerning low or high
temperature operation whenever temperature control equipment is in use. You should note
that the hazard from extreme temperature can extend beyond the immediate area of the test.

Crush Hazard - Take care when installing or removing a specimen, assembly,
structure, or load string component.
Installation or removal of a specimen, assembly, structure, or load string component
involves working inside the hazard area between the grips or fixtures. When working in this
area, ensure that other personnel cannot operate any of the system controls. Keep clear of
the jaws of a grip or fixture at all times. Keep clear of the hazard area between the grips or
fixtures during actuator or crosshead movement. Ensure that all actuator or crosshead
movements necessary for installation or removal are slow and, where possible, at a low
force setting.
Hazard - Do not place a testing system off-line from computer control without first
ensuring that no actuator or crosshead movement will occur upon transfer to manual
control.
The actuator or crosshead will immediately respond to manual control settings when the
system is placed off-line from computer control. Before transferring to manual control,
make sure that the control settings are such that unexpected actuator or crosshead movement
cannot occur.
Robotic Motion Hazard - Keep clear of the operating envelope of a robotic device
unless the device is de-activated.
The robot in an automated testing system presents a hazard because its movements are hard
to predict. The robot can go instantly from a waiting state to high speed operation in several
axes of motion. During system operation, keep away from the operating envelope of the
robot. De-activate the robot before entering the envelope for any purpose, such as reloading
the specimen magazine.
Hazard - Set the appropriate limits before performing loop tuning or running
waveforms or tests.
Operational limits are included within your testing system to suspend motion or shut off the
system when upper and/or lower bounds of actuator or crosshead travel, or force or strain,
are reached during testing. Correct setting of operational limits by the operator, prior to
testing, will reduce the risk of damage to test article and system and associated hazard to the
operator.
Electrical Hazard - Disconnect the electrical power supply before removing the
covers to electrical equipment.
Disconnect equipment from the electrical power supply before removing any electrical
safety covers or replacing fuses. Do not reconnect the power source while the covers are
removed. Refit covers as soon as possible.
Warnings
Rotating Machinery Hazard - Disconnect power supplies before removing the covers
to rotating machinery.
Disconnect equipment from all power supplies before removing any cover which gives
access to rotating machinery. Do not reconnect any power supply while the covers are
removed unless you are specifically instructed to do so in the manual. If the equipment
needs to be operated to perform maintenance tasks with the covers removed, ensure that all
loose clothing, long hair, etc. is tied back. Refit covers as soon as possible.
Hazard - Shut down the hydraulic power supply and discharge hydraulic pressure
before disconnection of any hydraulic fluid coupling.
Do not disconnect any hydraulic coupling without first shutting down the hydraulic power
supply and discharging stored pressure to zero. Tie down or otherwise secure all pressurized
hoses to prevent movement during system operation and to prevent the hose from whipping
about in the event of a rupture.
Hazard - Shut off the supply of compressed gas and discharge residual gas pressure
before you disconnect any compressed gas coupling.
Do not release gas connections without first disconnecting the gas supply and discharging
any residual pressure to zero.
Explosion Hazard - Wear eye protection and use protective shields or screens
whenever any possibility exists of a hazard from the failure of a specimen, assembly
or structure under test.
Wear eye protection and use protective shields or screens whenever a risk of injury to
operators and observers exists from the failure of a test specimen, assembly or structure,
particularly where explosive disintegration may occur. Due to the wide range of specimen
materials, assemblies or structures that may be tested, any hazard resulting from the failure
of a test specimen, assembly or structure is entirely the responsibility of the owner and the
user of the equipment.
Hazard - Ensure components of the load string are correctly pre-loaded to minimize
the risk of fatigue failure.
Dynamic systems, especially where load reversals through zero are occurring, are at risk of
fatigue cracks developing if components of the load string are not correctly pre-loaded to
one another. Apply the specified torque to all load string fasteners and the correct setting to
wedge washers or spiral washers. Visually inspect highly stressed components such as grips
and threaded adapters prior to every fatigue test for signs of wear or fatigue damage.

Intended use and
foreseeable
misuse:
When equipped with appropriate fixtures, the system is intended to conduct torsion tests
on a variety of specimen shapes and material types. The system is equipped with a
guard that encloses the test space. The guard is intended to protect operators from
rotating components and hazardous specimen conditions. The system can operate in
servo control mode only through an Instron Materials Testing Software package. An
operator must be present at all times while the system is in operation.
The system should not be used for any purpose other than torsion testing. The system
must not be used as a lathe. The system is not designed for testing any specimen that
contains liquids; consult Instron for these applications. The interlocking devices and
other hardware components provided with the guard must not be defeated or disabled.
The system should not be operated by anyone who does not fit the criteria specified in
the “Operator characteristics:” and “Operator training/experience:” sections of this
table.

2. The usable frame capacity is limited by the capacity of the torque cell used. Torque cells are available in a range of
capacities, refer to “Torque cell” on page 3-4 for more information.
3. Long term static tests should be limited to 30 minutes or less when the test is performed at or near maximum capacity.
Time varies inversely with test load. 50% maximum capacity tests should be limited to 60 minutes or less. Test duration
is ultimately limited by the temperature of the drive motor. Assumes ambient temperature of 25 deg C (77 deg F).
4. The design capacity is the peak load that the frame should be used at for no more than 80% of the time. In other words,
at least 80% of specimen testing should be conducted at peak loads that are at or below the design capacity. The frame
should only be used at loads between the design capacity and the maximum capacity less than 20% of the time.
5. Use of linear guide covers reduces the usable test opening. When linear guide covers are purchased and installed, they
can be removed to increase the usable test opening up to the maximum opening.
6. Includes clearance above and behind the frame to open the enclosure door and includes feet height of 51 mm (2 in).
Does not include clearance to mount optional axial preload assembly (requires clearance of 230 mm (9 in) on each side
of frame).
7. Does not include weight of any fixtures or optional accessories that can be mounted in frame.
8. Under no load conditions.
9. Frame only. Does not include torque cell or load string. Value measured flange to flange in test space with crosshead in
the closest position to the output shaft.
Table 2-2. MT frame technical specifications.
Specification1
MT1
MT2
The crosshead of the MT frame has been aligned at the factory to be within 0.125 mm (0.005 in) in
both the horizontal and vertical planes, with respect to the output shaft, when the output flange and
the torque cell assembly are face-to-face. This alignment decreases by 0.025 mm (0.001 in) for
every 25 mm (1 in) that the flanges are separated. The use of specimen fixtures automatically
reduces the alignment of the load train. The degree of misalignment depends on the specimen
fixture installed.
For MT1 frames, if alignment is critical for the test being performed, an optional alignment device
may be purchased to further improve the alignment of the load train with respect to the frame.

Environmental conditions
Table 2-4 lists the recommended environmental conditions in which the system should be operated
and stored.
Noise level
The A-weighted emission sound pressure level generated by the testing system under normal
operating conditions does not exceed 70 dBA. The peak C-weighted instantaneous sound pressure
value does not exceed 63 Pa.
Since many variables (such as room layout) affect noise levels, it can not be assumed that these
readings will be equal to those in the field. The readings were taken at a location in front of the
system as shown in Figure 2-1. This is the typical location for an operator to stand when operating
the system.

Operation of enclosure
The enclosure is interlocked. It affects operation of the system as follows:
•
When the enclosure is opened, the output shaft can only be operated by the JOG controls on the
user control panel. This permits installation of the specimen and other test setup.
•
The enclosure must be closed to start a test.
•
If the enclosure is opened during a test, the controls will abort the test and immediately stop the
output shaft. When a test is aborted, the controls will not automatically return the frame to start
or to gauge length, etc. To restart an aborted test, the frame must be manually returned to the
starting position and then the test can be restarted.
•
The enclosure can only be opened during a test if the frame is in a “pause” state (i.e. to remove
an extensometer). This action must be programmed into the test method. The test will
automatically continue once the enclosure is closed and the “Remove Extensometer” message is
cleared in the software.
•
Anytime the enclosure is opened, the controlling software indicates this by flashing an
“Interlock Open” message on the screen.

Operation of controls
Product Support: www.instron.com
Jog Controls
User
control
panel
Press the
or
button to rotate the output shaft counterclockwise or
clockwise. If you press and hold the button, the output shaft begins to move slowly.
As you continue to hold the button, shaft speed increases linearly, up to a preset
maximum, until you release the button.
When a specimen is installed,
rotation of the output shaft creates a clockwise
rotation of the torque cell - this is interpreted in the software as positive angular
displacement of the specimen and a positive torsional load on the specimen.
Likewise for
rotation of the output shaft; it creates negative angular
displacement of the specimen and a negative torsional load on the specimen.
FINE POSITION
User
control
panel
Turn this thumbwheel for slow but accurate positioning of the output shaft. FINE
POSITION allows you to set an accurate gauge length, or to set a precise grip
position for loading specimens. Direction of output shaft rotation produces the same

Press this button to set the current angle of the output shaft as the gauge length
angle. Once the gauge length is set, the output shaft always returns to this angle
when:
•
The output shaft encounters a pre-set limit or event and the software instructs the
output shaft to return to gauge length.
•
You press the RETURN button (with Bluehill software only).
AT GL
Indicator
User

Location
Description
The torsional force applied to the specimen by the drive motor can be measured by an optional strain
gauge torsion load cell, or torque cell. See “Torque cell options” on page 1-5 for a list of available
torque cells; several capacities are available.
Torque cells with a capacity of 22.5 N-m (200 lbf-in) or less are miniature torque cells. Miniature
torque cells are very sensitive and can be damaged very easily. Most damage occurs when fixtures
or specimens are mounted to the torque cell - the simple act of securing a fixture or specimen to the
torque cell can generate enough torsional force to overload and damage the torque cell. For this
reason, all miniature torque cells that are purchased from Instron are supplied with special plates
mounted to the front and rear of the torque cell. This torque cell assembly (1, Figure 3-2) is designed
to be mounted in a torque cell protection device. For MT1 frames, this protection device is supplied
as standard equipment with the frame. For MT2 frames, the protection device can be purchased as

optional equipment. The protection devices only protect the miniature torque cell during installation
of fixtures or specimens - they do not protect the miniature torque cell from overload during a test.
Select torque cell
Selecting a torque cell is the first step in preparing for a torsion test. If the approximate strength of
the specimen is known, use these guidelines to choose a torque cell:
•
The maximum expected testing torque must be less than the maximum capacity of the torque
cell but greater than 2% of the maximum capacity of the torque cell.
•
If a choice is possible between two different cells because of overlapping ranges:
•
Select a higher-capacity torque cell whenever a minimum deflection is desired.
•
Select a lower-capacity torque cell whenever a maximum long term balance or stability is
desired.
If the specimen’s strength is not known, refer to a Properties of Materials handbook to obtain an
approximate strength.
If you cannot determine an approximate value of strength, use the highest capacity torque cell rated
for the frame. Perform a preliminary test at a very slow speed to obtain the torque range required.
After performing the preliminary test, you can determine if a lower capacity torque cell will provide
better resolution.
Mount torque cell - MT1 frames
MT1 frames use a miniature torque cell for measuring the torsional load on a specimen. For this
reason, MT1 frames include a standard torque cell protection device (2, Figure 3-3) to mount the
miniature torque cell assembly (1). The torque cell protection device is mounted to the
crosshead (3).
The clamp lever (2b) is used to engage and disengage the torque cell assembly in the protection
device housing (2a):
•
When the clamp lever is put in the engaged (vertical) position, the torque cell assembly (1) is
pulled back into the housing (2) so that each engagement pin (1e) is in the head of its slot (2d).
There is enough clearance in the head area to allow rotation of the face plate and thus torsional
force is transmitted to the torque cell.

Crosshead
When the clamp lever is put in the disengaged (horizontal) position, the torque cell assembly is
pushed forward in the housing so that each engagement pin is in the neck of its slot (2e). The
neck area has minimal clearance and does not allow the face plate to rotate, and thus no torsional
force is transmitted to the torque cell.
The clamp lever should always be in the disengaged position before any fixtures or specimens are
mounted to the torque cell assembly and in the engaged position for testing. It is very important to
follow proper procedures when installing and removing the miniature torque cell assembly from the
protection device (see page 3-7) AND when installing and removing fixtures and specimens from
the torque cell assembly (see “Fixture mounting” on page 3-10).
Caution
It is always good practice to disengage the torque cell assembly anytime it is not directly in
use. This prevents accidental damage to the torque cell.

Installation of miniature torque cell assembly
Caution
Extreme caution must be used when installing a torque cell assembly into the torque cell
protection device. It is extremely easy to damage the torque cell. Be sure to follow
recommended procedures.
When the system arrives from the factory, the miniature torque cell assembly will be fully assembled
with the face and base plates already attached. It is only necessary to install the assembly into the
housing.
Equipment required
You will need the following equipment:
•
A 5 mm hex key (supplied)
Recommended procedure:
Perform the following procedure to install a miniature torque cell assembly:
1.
Put the torque cell clamp lever (6a, Figure 3-3) in the disengaged position.
2.
Carefully insert the miniature torque cell assembly into the housing - the end with the clamp bolt
should go in first. Be sure that the torque cell cable (1f) lines up with the cable slot (2f) and that
the engagement pins (1e) line up with their engagement slots (2e).
3.
Insert the 5 mm hex key through the access hole (1g) on the front of the face plate and thread the
clamp bolt (1d) into the plunger (2c) two to three turns.
4.
Put the torque cell clamp lever in the engaged position and continue turning the clamp bolt until
it just starts to tighten.
5.
Check for proper tightness of the clamp bolt by disengaging and engaging the torque cell clamp.
The lever should lock firmly in place when engaged. If it is loose and does not snap into place,
the clamp bolt is too loose and must be tightened. If the lever cannot be lifted into the engaged
position, the clamp bolt is too tight and must be loosened. Use small adjustments of the hex key
to get the right tension on the torque cell clamp for locking.
6.
Disengage the torque cell assembly.
7.
Be sure the torque cell cable is plugged into the LOAD connection on the front of the 59 Series
control unit.
Removal of miniature torque cell assembly
Caution
Extreme caution must be used when removing a torque cell assembly from the torque cell
protection device. It is extremely easy to damage the torque cell. Be sure to follow
recommended procedures.
It should only be necessary to remove the torque cell assembly from the torque cell protection device
if a different torque cell assembly must be used or if the torque cell is damaged and must be replaced.
Equipment required
You will need the following equipment:
•
A 5 mm hex key (supplied)
Recommended procedure:
Perform the following procedure to remove a miniature torque cell assembly:
1.
Disengage the torque cell assembly.
2.
Unplug the torque cell cable from the LOAD connection on the front of the 59 Series control
unit.
3.
Insert the 5 mm hex key through the access hole (1g) on the front of the face plate and
completely loosen the clamp bolt (1d).
4.
Carefully remove the torque cell assembly from the housing.

Mount torque cell - MT2 frames
For MT2 frames, the torque cell mounts to the crosshead. When using the full capacity torque cell
(225 N-m (2,000 in-lbf)), it mounts directly to the crosshead as shown in Figure 1-2 on page 1-8 - no
special mounting is needed. When miniature torque cells are used with an MT2 frame, an optional
torque cell protection device (which is similar to the torque cell protection device on the MT1
frames) can be purchased, and is highly recommended, to provide protection for the miniature
torque cell. When purchased, this torque cell protection device is supplied with separate instructions
for installation and use. The torque cell protection device mounts directly to the crosshead.
Torque cell setup
Once a torque cell is chosen, installed and connected, the system should recognize the selected cell.
The type and full scale rating of the cell are recalled. If the software’s torque cell display shows
“Not Calibrated”, the torque cell needs calibrated. Click on the Transducer drop-down menu, select
Calibrate, and then select the applicable torque cell from the drop-down list. The software will
perform a calibration. Follow the prompts as instructed.
The gain settings for the torque cell are set at the factory. These settings can be modified, if needed,
for a particular specimen stiffness. For systems with Bluehill software, refer to the on-line Help
system for guidance on determining gain settings. For systems with Partner software, the gain
setting of the torque cell can be changed as follows:
1.
Click on Tools > Configure > Transducers.
2.
Select the appropriate torque cell from the list and click the Modify button.
3.
Select the Scaling tab. The Stiffness Compensator value sets the torque cell gain. The default
value of 0.01 is usually sufficient. This gain number may need adjusted depending on specimen
compliance. For more elastic specimens, try a larger number (i.e. 0.015 or 0.02). If the machine
oscillates, gain is probably set too high. Try entering a smaller number (i.e. 0.008 or 0.005).
Caution
Do not test with specimens that exceed the torque cell testing capacity. This may cause
severe oscillation and failure of the torque cell. Always test with a specimen smaller than cell
capacity. If capacity is unknown, start the test at a very low gain setting (0.001 or lower) and
slowly increase gain to find the optimum setting.
Current production torque cells use a programmed serial prom to allow the controlling software to
automatically identify the torque cell. If you want to use an older torque cell that is identified by the
software using resistor identification (instead of a serial prom), then you should contact your local
Instron Professional Services department as directed on page 1-12 for guidance.
The frame is supplied with multiple bolt patterns for the mounting of specimen gripping fixtures.
The bolt patterns are designed to allow standard Instron torsion fixtures to be mounted in the test
space. Any bolt pattern can also be used to mount customer fixtures or accessories; appropriate
adaptation may be necessary. All bolt patterns can accommodate testing at full frame capacity. The
following sections provide details of the bolt patterns - refer to the appropriate section for your
frame. For MT1 frames that use miniature torque cells, the recommended procedure to mount
fixtures to the torque cell is also included. It is very important to follow the recommended procedure
to prevent damage to the miniature torque cell.
MT1 frames
For MT1 frames, fixtures are mounted to the output shaft (1, Figure 3-4) and the face plate of the
torque cell assembly (2). Details of the bolt patterns provided on both surfaces are provided in
Figure 3-4. To mount fixtures to the torque cell assembly without causing damage to the torque cell,
perform the following recommended procedure.
Caution
It is very important to follow recommended procedures when accessories are mounted to the
miniature torque cell assembly. Damage to torque cell will result if fixtures are not mounted
as recommended.
Caution
It is always good practice to disengage the miniature torque cell assembly anytime it is not
directly in use. This prevents accidental damage to the torque cell.
Before mounting any fixture to the torque cell assembly, be sure the desired miniature torque cell
assembly is properly installed in the torque cell protection device. See page 3-7 and page 3-8 for
installation and removal procedures.
1.
Disengage the torque cell assembly.
2.
Tighten the crosshead clamp (7, Figure 1-2 on page 1-8) to secure the crosshead in place.
3.
Attach the desired fixture to the face plate of the torque cell assembly (2, Figure 3-4).
4.
Once the accessory is completely mounted and any bolts are tightened as desired, the torque cell
assembly can be engaged; however, it is recommended that the torque cell assembly remain
disengaged until just before any test is started. This will prevent accidental damage to the torque
cell.
To remove fixtures, reverse the above procedure. Always be sure to disengage the torque cell
assembly before attempting to loosen or tighten fixture mounting bolts.
When mounting a fixture to the output shaft, the output shaft may rotate if the frame is not enabled.
If this rotation is objectionable, enable the frame in the controlling software.

For MT2 frames, fixtures are mounted to adapter plates (3, Figure 3-4). These adapter plates are
mounted to the output shaft (1) and torque cell face plate (2). Details of the bolt patterns provided on
the adapter plates are provided in Figure 3-4.
Alternatively, one or both adapter plates can be removed so that fixtures can be mounted directly to
the output shaft and/or torque cell face plate. The output shaft and torque cell face plate provide a
bolt pattern of through-holes only (no tapped holes) - details of the bolt pattern are provided in
Figure 3-4. Removal of both adapter plates increases the available test opening by approximately
57 mm (2.25 in). When removing the adapter plates, be careful not to lose the centering disks (4).
When re-installing the adapter plates, put a centering disk in the recess on the rear of each adapter
plate to help align the adapter plates with the output shaft and torque cell face plate.
When mounting a fixture to the output shaft, the output shaft may rotate if the frame is not enabled.
If this rotation is objectionable, enable the frame in the controlling software.

adjusting this frequency as experience dictates.
2. Whichever is soonest.
Make daily checks of system
Product Support: www.instron.com
Make daily checks of system
Before operating the system each day, a general check of the system is highly recommended.
Performing a good general check on a daily basis is an important part of preventative maintenance.
It also allows the operator to become familiar with the system, and with what is considered normal
behavior and normal appearance. Once familiar with the system, operators will be more likely to
notice any abnormalities that could indicate problems, or potential problems, with the system.
Before operating the system each day:
•
Check that the crosshead is square to the guide rail and not out of alignment. This can be a
simple visual check. Stand away from the frame and check that all horizontal components (i.e.
the base, guide rail and crosshead) are parallel with each other and aligned vertically.
Misalignment indicates that a larger problem exists.
•
Check that all testing accessories are free of dirt, damage and deformation. Any fixture with
damage or deformation should be corrected before use!
•
Check that power is adequately supplied to the electronics. Start up the system and check all
indicator lights on the user control panel and 59 Series control unit. Check that the lights are not
too bright or too dim, and that they don’t flicker. If any of these conditions exist, this could
indicate a problem with the power supply in the 59 Series control unit or with system main
power (customer supply).
•
Check that all cables are free of wear and chafing, have adequate slack to prevent excessive
strain on connectors, and have tight connections.
If any of these checks reveal a potential problem, the problem should be investigated and corrected
before the system is operated. For assistance in troubleshooting the system, contact your local
Instron Services department as directed on page 1-12.
Clean the fans
The fan opening of the 59 Series control unit and the computer system’s CPU should be cleaned at
the frequency stated in the “Preventative maintenance schedule” on page 4-2. The fan opening for
the 59 Series control unit is on the rear of the unit. Use a vacuum to remove dust and dirt from the
grill of the fan and the fan filter.
Fuses
The system is equipped with several fuses. These fuses should only need replaced when they are
blown. Refer to the system’s System Concepts Manual (supplied separately) for more information
on troubleshooting for a blown fuse.
Inspect the cables
Cables should be inspected at the frequency stated in the “Preventative maintenance schedule” on
page 4-2. Check the following:
•
Inspect all cables for loose connections. This includes power cable and transducer cable
connections at the frame and at the 59 Series control unit. Tighten any loose connections that
you may find.
•
Inspect all cables for deterioration. Check for abrasions, cuts, etc. Replace cables as necessary.
If you notice any problems resulting from this inspection, contact your local Instron Services
department as directed on page 1-12 for immediate assistance.
Product Support: www.instron.com
Frame
Clean, inspect and lubricate the guide rails
The guide rails should be cleaned, inspected and lubricated periodically, as outlined in the
“Preventative maintenance schedule” on page 4-2, to maintain smooth operation and prevent
corrosion. Use of a 3:1 mineral oil is recommended. Perform the following:
1.
For frames that are equipped with the optional guide covers, gain access to the guide rails by
loosening and removing the guide covers. The guide covers are held in place by Velcro®
fastener strips.
2.
Check the guide rails for cleanliness. If necessary, wipe the guide rails with a clean, dry cloth.
Move the crosshead as necessary to clean all parts of the guide rails.
3.
Inspect the guide rails for damage. Move the crosshead and check for smooth operation. Minor
damage is acceptable as long as it does not interfere with movement of the crosshead. If damage
is severe enough to hinder movement of the crosshead or to affect alignment between the output
shaft and torque cell, contact your local Instron Services department as directed on page 1-12 for
immediate assistance.
4.
Lubricate the guide rails. Apply a thin film of mineral oil to the guide rails. Move the crosshead
as necessary to lubricate all parts of the guide rails.
5.
For frames that are equipped with the optional guide covers, restore the guide covers to their
original position and press the Velcro® into place. Once guide covers are in place, move the
crosshead to check for smooth operation.
Ancillary parts for the MT systems are listed in Table 4-2. These ancillary parts are included with
the frame upon delivery. Be sure to keep these ancillary parts in a safe place so they do not get
misplaced.
Consumable parts
MT systems have no consumable parts.
Spare and replacement parts
The Instron Services department maintains a supply of parts for your system. In the event that your
system requires replacement parts, or if you choose to keep spare parts in stock, please contact your
local Instron Services department as directed on page 1-12 for the proper part. Parts can be
purchased individually as they are needed, or as a spare parts kit. There are three levels of spare
parts kits available, see Table 4-3 for descriptions of each kit and their part number.
