2 SETUP AND SAFETY
2.1 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.
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.
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 illustration below for
proper assembly:
In general, the ESM301 can be mounted at any angle, although extra care should be taken during
installation and operation.
When 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.
2.2 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 below for
proper installation:

2.4.1 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. When using a grip, ensure that it secures the sample in such a way that it is 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.
2.5 Connecting power
Plug one end of the power cord into its receptacle at the rear of the stand 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 electrically conductive liquids 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 column covers are removed.
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. 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. Long
hair should be covered to avoid a hazardous situation. 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.

User’s Guide
4. In those applications where samples can shatter, or other applications that could lead to a
hazardous situation, use of a machine guard is strongly recommended.
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.
5. Load Holding Mode
Crosshead moves to a force set point, stops, then dynamically adjusts position to maintain
the programmed force. An auto-return or cycle/dwell time sequence may follow.
6. Break Detection
Crosshead stops when a sample break has been detected. An auto-return or cycle/dwell time
sequence may follow.
7. PC Mode
See Communications section.
The Operating Mode home screen appears as follows:
S P E ED :

SET
The item selected will be capitalized, as shown in the figure above. The set speed can be changed in
Test Feature Setup. If enabled, the up and down speeds can be configured independently of each other
(UP SPEED and DN SPEED). Otherwise, the SPEED setting corresponds to crosshead speed in both
directions.
5.2 Menu Navigation

5.3 Basic Mode
The crosshead moves upward when UP is pressed, and downward when DOWN is pressed. When the
crosshead is in motion, an LED indicator on the button pushed will be illuminated. The KEYS setting
controls how crosshead movement responds to the push of the UP and DOWN buttons. The three
settings are:
19
Model ESM301 / ESM301L Test Stand
User’s Guide
1.
Maintained (default)
The crosshead will move continuously once the button has been pressed. Subsequently
pressing STOP will stop crosshead motion.
2.
Momentary
The crosshead will move only if the button is pressed and held. Releasing the button will
stop movement immediately.
3.
Auto
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.
Pressing EMERGENCY STOP will immediately stop crosshead motion in any mode. To release, rotate
clockwise. 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 for two seconds.
5.3.1 Travel Indication
If installed, travel indication is displayed in the upper left corner of the display. The displayed units are the
same as programmed in the UNITS feature. Indicated travel is a relative value. To zero the value, press
and hold STOP for two seconds.
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
installed and 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.
20
Model ESM301 / ESM301L Test Stand
User’s Guide
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 the
independent up and down speeds option is installed). 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.
5.5 Cycling Mode
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.
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 opposite direction. 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:
CYCL ES
00024
me n u m i n ma x
SET
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 :
0001 . 5
me n u m i n ma x
SET
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:
CYCL ES :
00024
RESE T
At this point, there are two options:
21
Model ESM301 / ESM301L Test Stand
User’s Guide
1. Cancel 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. Resume 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 the set speed (10 in/min [250 mm/min] maximum) 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 feature occurs. If the ZERO,GO setting is selected, and
if the set speed is greater than 10 in/min, the crosshead speed will revert to this setting after the travel
indicator is zeroed.
Note 1:
Before the start of a preload sequence, the crosshead must be positioned at either the upper or lower
physical limit switch.
Note 2:
Preload and Loadholding cannot be enabled simultaneously.
5.6 Loadholding 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, loadholding 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 loadholding or at the lower limit switch to begin tension loadholding.
An appropriate speed should be chosen for a given sample. Fine tuning may be necessary to ensure
optimal crosshead dynamic behavior. 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 loadholding period. This is typical for samples which may relax, such as rubber, foam, etc. Lowering
the test speed will reduce the oscillation.
22
Model ESM301 / ESM301L Test Stand
User’s Guide
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. This action occurs when the
force has decreased to a specified percentage of peak, as illustrated below:
If enabled, an auto-return sequence or single-cycle sequence may follow break detection.
6 COMMUNICATION

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 general purpose lithium 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.
9.3 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
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.
