2 MECHANICAL SETUP AND SAFETY
2.1 Safety / Proper Usage
Typical materials able to be tested by the ESM301 include many manufactured items, such as springs,
electronic components, fasteners, caps, films, mechanical assemblies, and many others. Items that
should not be used with the ESM301 include potentially flammable substances or products, items that
can shatter in an unsafe manner, and any other components that can present an exceedingly hazardous
situation when acted upon by a force.
1. Using Grips & Fixtures with the ESM301
Ensure that the grip or fixture is positioned to ensure axial load with respect to the loading shaft of
the force gauge.
prevented from slipping out during a test, preventing a potential safety risk to the operator and
others in the vicinity. If using a grip or fixture from a supplier other than Mark-10, ensure that it is
constructed of suitably rugged materials and components.
2. Mounting
Place the stand on a clean, flat and level work area free from vibration. If desired, the stand can
be secured to the work area with 1/4-20 screws fastened into the underside of the base. Failure
to properly mount the test stand may make it more vulnerable to tipping, causing a hazardous
situation.
The test stand can also be mounted using the
ESM301-003 mounting kit. Screws of various
lengths are supplied with this kit to accommodate a
range of bench thicknesses. Refer to the following
illustration at right proper assembly:
When using a grip, ensure that it secures the sample in such a way that it is
IMPORTANT: Do not fasten any screws more than
0.25 in [6 mm] into the base of the test stand, or
damage to internal components can occur.
In general, the ESM301 can be mounted at any angle, although extra care should be taken during
installation and operation.
Once the test stand is in a stable and secure position, install a force
gauge with four thumb screws (provided). Mark-10 gauges mount
directly without adapters. Grips can be mounted onto the force gauge
and test stand base.
3. Installing the limit switches
Upper and lower limit switches are provided to stop crosshead travel at
user-designated positions. Each limit switch consists of an internal
block riding along a rail, and an external thumbscrew. The
thumbscrews are shipped in a separate bag to avoid damage in transit.
Refer to the illustration at right for proper installation:

Plug one end of the cable into this connector, and the other end into the connector as shown in
the illustration on the right.
3. PC Output Connector
Outputs force only or force and travel data via RS-232. Also allows for PC control, if appropriate
features are enabled. Plug one end of the 09-1056 serial cable into this connector, and the other
end into a serial connector on a computer.
4. Power Plug Receptacle
Plug the power cord in here.
5. Travel Indication Connector
Plug one end of the USB/RJ11 cable into this connector, and the other end into the mini USB
connector in the rear of the crosshead.
6. Force Gauge Cable Connector
Interfaces with a Series 5 or 4 force gauge. Plug one end of the 09-1162 cable into this
connector, and the other end into the gauge.
2.3 Connecting Power
Plug one end of the power cord into its receptacle at the rear of the controller and the other end into a
wall outlet with local earth ground (3-prong connector).
Before turning on power, the following safety checks and procedures should be performed:
1. Never operate the test stand if there is any visible damage to the power cord or the test stand
itself. The ESM301 is powered by 110V/220V. Any contact with this high voltage can cause
serious injury or even death.
2. Ensure that the test stand is kept away from water or any other electrically conductive liquids
5
Model ESM301 / ESM301L Version 2 Test Stand User’s Guide
at all times.
3. Make sure the electrical outlet powering the test stand has local earth ground (3-prong
connector).
4. The test stand should be serviced by a trained technician only. Power must be disconnected
before the controller is opened.
After the above safety checks and procedures have been performed, the test stand may be powered on
and is ready for operation.
3 OPERATION BASICS
3.1 Operational Safety
The following safety checks and procedures should be performed before and during operation:
1. Always consider the characteristics of the sample being tested before initiating a test. A risk
assessment should be carried out beforehand to ensure that all safety measures have been
addressed and implemented.
2. Wear eye and face protection when testing, especially when testing brittle samples that have the
potential to shatter under force. Although the ESM301 has relatively slow moving mechanisms, be
aware of the dangers posed by potential energy that can accumulate in the sample during testing.
Extra bodily protection should be worn if a destructive failure of a test sample is possible.
3. Keep away from moving parts of the test stand. Loose articles of clothing should not be worn, and
long hair should be covered to avoid being caught in any moving parts. A Crush Hazard warning
label is located on the base of the test stand. It appears as follows:
Definition: Keep any body parts and clothing clear of the area between the base of the test stand and the
moving crosshead.
4. In certain applications, such as the testing of brittle samples that can shatter, or other applications
that could lead to a hazardous situation, it is strongly recommended that a machine guarding
system be employed to protect the operator and others in the vicinity from shards or debris.
5. When the test stand is not in use, ensure that the power is turned off to prevent accidental
engagement of any of the controls.

5 OPERATING MODES
5.1 Mode Overview
The ESM301 can be operated in several modes, including combinations of these modes:
1. Basic Mode
Manual control of crosshead motion.
2. Auto Return Mode
Crosshead moves to a limit switch or force set point, travel distance, preload, or sample
break (referred to as soft limits), whichever occurs first. Then, it reverses and moves at
maximum speed to the other limit, whichever occurs first.
3. Cycling Mode
Crosshead cycles between limits at the selected speed(s), and pauses at each limit or set
point for a selected period of time.
4. Preload Mode
Crosshead moves until the preload has been reached, and performs the action programmed
in the setting. An auto-return, cycle/dwell time, or break detection sequence may follow.
16

The password is a four digit number. The first digit in the password will be flashing, signifying that
it is active and can be incremented by pressing +. To advance to the next digit, press –>. Change
subsequent digits in the same fashion. Once the complete password has been entered, press
ENTR. If correct, the display will enter Test Parameter Setup Mode. If the password is incorrect,
the words INCORRECT PASSWORD will flash, and the display will revert to Operating Mode.
The crosshead will move continuously once the button has been pressed. Subsequently
pressing STOP during a test will stop crosshead motion.
The crosshead will move only if the button is pressed and held. Releasing the button will
stop movement immediately.
Holding down the button for more than 0.5 seconds will enter Momentary mode, at which
time an audible indicator will sound and the LED indicator on the button pushed will be
illuminated. A short tap on the button will operate the test stand in Maintained mode.
Pressing STOP during Maintained mode will stop crosshead motion. To resume the test,
press UP or DOWN again.

button counter-clockwise until it assumes its original position. To resume the test, press UP or DOWN.
Crosshead movement will take place until a limit has been reached. If the crosshead has stopped at a
soft limit, the limit condition may be overridden by pressing and holding UP or DOWN.
5.3.1 Travel Indication
If enabled, travel indication is displayed in the upper left corner of the display. The displayed units are the
same as programmed in the UNITS parameter. Indicated travel is a relative value. To zero out travel
distance, ensure that the crosshead is not moving, then press and hold STOP.
If the cable connecting the crosshead to the rear of the controller is unplugged, the position value will not
change when the crosshead moves.
5.3.2 Limit Switch Operation
Limit switches allow the operator to set a location along the column at which
point the crosshead will stop moving. Limit switches are located at the rear of
the test stand column, as shown in the image to the left. Adjust the switches’
positions by loosening, repositioning, and re-tightening the thumb screws. The
thumb screws must be installed after unpacking. They are shipped separately
to avoid damage in transit.
5.3.3 Overload Protection
The 09-1162 cable is required for overload protection of a Mark-10 force gauge. If overload protection is
enabled, the crosshead will stop when the programmed percentage of full scale of the force gauge has
been reached.
When overload protection is enabled, if the 09-1162 cable is disconnected, and/or if the force gauge is
turned off, an error message will appear. Plug in the cable and/or turn on the force gauge to clear the
message.
Note: When the crosshead is moving in the UP direction, only the tension overload setting is active.
When the crosshead is moving in the DOWN direction, only the compression overload setting is active.
5.4 Auto Return Mode
In this mode the crosshead moves to whichever limit it encounters first and stops. Then, the crosshead
returns at maximum speed to the other limit, whichever occurs first, and stops. The speed at which the
crosshead travels is dictated by the SPEED setting or UP SPEED and DN SPEED settings (if
independent speeds are enabled). Press UP or DOWN to initiate an Auto Return sequence.
The crosshead can be stopped at any time during an Auto Return sequence by pressing STOP. To
resume the test, press UP or DOWN.
Note: If the crosshead has stopped at a soft limit, the limit condition may be overridden by pressing and
holding UP or DOWN for two seconds.
ycling Mode
5.5 C
This mode cycles the crosshead between limits, whichever occurs first. One cycle consists of the
following steps:
1. Crosshead moves to a limit at the specified speed.
2. Crosshead stops for the specified amount of dwell time.
19
Model ESM301 / ESM301L Version 2 Test Stand User’s Guide
3. Crosshead reverses direction, returns to the other limit at the specified speed, and stops for
the specified amount of dwell time.
A cycling sequence can be initiated from any position and can start in either direction. If the crosshead is
at a limit, however, cycling can only be started in the direction of the other limit. To initiate a cycle
sequence, press UP or DOWN. During a cycle sequence, a counter will be displayed, indicating the
number of cycles remaining, as shown below:
C Y C L E S 0 0 0 2 4
me n u m i n ma x S E T
As in Basic Mode, the min, max, and set soft keys are active during crosshead movement.
When the cycling sequence and the crosshead has stopped at a soft limit, the limit condition may be
overridden by pressing and holding UP or DOWN.
5.5.1 Dwell time
Dwell time is the amount of time, in seconds, for which the crosshead stops at a limit during a cycle
sequence. When the crosshead has reached a limit, a counter will be displayed, shown as follows:
D WE L L : 0 0 0 1 . 5
me n u m i n ma x S E T
If the DWELL U and/or DWELL L settings are set to 0, the crosshead will immediately reverse direction
upon reaching the corresponding limit, and no counter will be displayed.
The cycle sequence may be interrupted before it has been completed by pressing STOP. A soft key
labeled RESET will appear as follows:
C Y C L E S : 0 0 0 2 4
R E S E T
At this point, there are two options:
1. Canceling the cycle sequence:
Press RESET to stop and reset the cycle sequence. The cycle counter will revert to the
number of cycles originally programmed.
2. Resuming the cycle sequence:
Press UP or DOWN to resume.
Once the sequence has been completed, the screen will revert to the number of cycles programmed
originally. To begin another cycle test, press UP or DOWN.
Travel indication and limit switch operation is the same as in Basic Mode.
5.5 Preload Mode
In this mode, the crosshead moves at an approach speed of 10 in/min (250 mm/min) until the
programmed preload value has been reached. If moving in the up direction, a tension preload is required.
If moving in the down direction, a compression preload is required. When the preload is reached, the
sequence of events programmed in the Preload setting occurs (see Section 4.7.1). If the ZERO,GO
setting is selected, the crosshead speed will revert to the set speed after travel indicator is zeroed.
Note 1: Before the start of a preload sequence, the crosshead must be positioned at either the upper or
20
Model ESM301 / ESM301L Version 2 Test Stand User’s Guide
lower limit switch.
Note 2: Preload and Load Holding cannot be enabled simultaneously.
5.6 Load Holding Mode
In this mode, the crosshead moves until the set point value programmed in the force gauge is reached.
The crosshead then dynamically adjusts its position to maintain a programmed force. The force gauge’s
capacity should be as close as possible to the intended load, for best performance.
In the force gauge, both set points must be set. The upper set point refers to a force limit in the up
(tension) direction. The lower set point refers to a force limit in the down (compression) direction. The
opposite set point must be set to any value in the opposite measuring direction. For example, for a test
requiring load holding at 10 lbF of compression force, set the upper set point to 30 lbF tension (as an
example), and the lower set point to 10 lbF compression.
If the CYCLING option has been enabled, load holding will be active for the period of time as defined in
the Dwell Time settings. If CYCLING has not been enabled, load holding will continue indefinitely.
Before the start of a load holding sequence, the crosshead must be positioned at either the upper limit
switch to begin compression load holding or at the lower limit switch to begin tension load holding.
The test speed should be adjusted according to the sample under test. Fine tuning may be necessary to
ensure optimal crosshead dynamic adjustment. Stiff samples require a lower test speed; softer samples
can be tested at higher speeds. If the speed of approach is too high for a given sample stiffness, the
crosshead may overshoot the set point value, requiring an adjustment sequence where the crosshead
reverses, then moves again in the original direction multiple times before settling at the set point value. A
high enough speed may cause this correction cycle to repeat indefinitely.
For softer samples the amplitude of oscillation will be smaller, but could still be present for the duration of
the load holding period. This is typical for samples which may relax, such as rubber, foam, etc. Lowering
the test speed will reduce the oscillation.
For non-relaxing materials such as metal springs, the oscillation should stop shortly after the holding force
is reached.
Note: Preload and Load Holding cannot be enabled simultaneously.
5.7 Break Detection Mode
In this mode, the crosshead will stop when a sample break has occurred. The test stand is triggered when
the force has decreased to a specified percentage of peak.
For example: A sample is pulled until 50 lbF, then breaks. The break detection percentage drop setting is
programmed to 50%. After the sample breaks, the force rapidly decreases, reaches 25 lbF (50% of peak),
then triggers the test stand to stop.
Break detection becomes active only after 5% of the force gauge’s full scale has been reached. For
example, if a force gauge with 50 lbF capacity is used, the break detection feature will not become active
until 2.5 lbF has been reached.
If enabled, an auto-return sequence or single-cycle sequence may follow break detection.
5.8 PC Mode
The ESM301 can be controlled by a PC via serial communication. A list of supported ASCII commands is
provided below. All commands must be lowercase.

q Request number of cycles completed
r Request number of cycles set
s Stop crosshead
t Reset cycle counter to zero
u Move crosshead up
v Request upper travel limit
w Request lower travel limit
x Request travel value
z Reset travel to zero
*The transmission of ASCII “p” will return the stand status. The following are the return codes and their
definitions:
Crosshead status U = crosshead moving up
D = crosshead moving down
S = crosshead stopped
Operating mode C = cycle mode
L = limit mode
M = manual mode
Limit switch status UL = crosshead at upper limit
DL = crosshead at lower limit
Commands relating to Mark-10 force gauges are not the same as indicated in their respective user’s
guides. A list of supported ASCII commands is provided below. All commands must be uppercase:
A Displays current unit
F Toggles between Normal and Data Collect modes
P Steps through Normal mode, Tension Peak mode, and Compression Peak mode
R Zeroes the force gauge (zeroes all modes)
S Sends current mode (Normal, Tension Peak, Compression Peak, or Data Collect)
U Steps through units
X or ? Sends currently displayed reading
Y Enables RS-232 output and sends continuous data stream when in Data Collect mode
Z Zeroes the peak values
The ESM301 is compatible with legacy Nexygen
TM
TCD software, which also utilizes the above
commands. The 09-1162 cable is needed to communicate between a Mark-10 gauge and the test stand.
The 09-1056 serial cable is needed to communicate between a PC and the test stand. Baud rate, stop
bits and parity must be programmed in the stand to correspond with the PC software’s settings.
While in PC control, if any parameters are changed on the front panel, these settings will be ignored,
except if Auto Return or Cycling are turned on. If so, PC control will be turned off automatically.

stand controller. Message appears when overload protection is
turned on.
The stand is attempting to move the crosshead up or down, but it
cannot establish communication with the force gauge. The
communication settings in the force gauge are not correct or the
gauge is in a menu.
The programmed overload percentage of the force gauge’s full scale
has been reached. Immediately reduce the force or adjust the
overload settings.
A Series 5 force gauge with firmware version 1.7 or later is required
for proper operation of the selected functions in the stand.

To clear any of the above errors, press STOP. The amber light in the STOP button will be blinking
when the error message is displayed.
2. The crosshead will move only in one direction, or not at all.
Possible causes:
1. Ensure all cables are plugged in properly, as described in Section 2.2.
2. Ensure that the force value has not exceeded the overload limits configured in the gauge.
3. Ensure that force gauge set points have been configured properly. Refer to Section 5.6 for
details.
3. The travel display value does not change when the crosshead moves.
Check to make sure the encoder cable is plugged in properly.
4. Certain menu items are no longer displayed.
All test stand functions are temporarily enabled for 160 hours of operation in Demo Mode. When
demo mode has expired, any functions (and their associated menu items) not originally
purchased will no longer be available.
9 MAINTENANCE AND SERVICE
The ESM301 should be operated in a dry and clean area. Under these circumstances only a few periodic
maintenance operations are required:
9.1 Acme screw lubrication – twice per year
1. Remove the right column cover by loosening the screws, as shown above.
2. Using a brush, apply a small amount of silicon-based grease to the lead screw.
3. Cycle the crosshead up and down several times until the newly applied grease has been spread
evenly over the length of the screw. Re-install the column cover.
9.2 Check for loosened grips and attachments - daily
Check to ensure that the grips attached to the force gauge and base plate are firmly secured. Looseness
could result in a potentially hazardous situation.
Check for loosened components – once per month
1. Remove the test sample from the test stand.
2. Turn off power to the test stand and disconnect the power cord. Attempt to loosen
25
Model ESM301 / ESM301L Version 2 Test Stand User’s Guide
subcomponents of the test stand (ex. fasteners, brackets, etc). All components should be firmly
attached. If any looseness is detected, stop using the test stand and contact Mark-10 or a
distributor for instructions.
