Model ESM303 Test Stand

User’s Guide

If using test stand functions requiring communication between the force gauge and test stand, such as data output, overload protection, preload, etc., connect the interface cable between the instrument’s connector and the crosshead’s connector. This cable may be used with a Series 4, 5, or 7 instrument.

Refer to the image below:

Note:

The 09-1214 cable powers the instrument. When connected, the instrument automatically powers on when the test stand is powered on. The instrument’s AC adapter is not necessary under these conditions.

2.5 Safety / Proper Usage

Typical materials able to be tested by the ESM303 include many raw materials and manufactured items, such as springs, metals, plastics, electronic components, mechanical assemblies, packaging materials, and many others. Items that should not be used with the ESM303 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.

Ensure that the grip or fixture is positioned to ensure axial load with respect to the load axis of the load cell or 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.

2.6 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 ESM303 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.

3.1 Operational Safety

User’s Guide

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.

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 Overview

The ESM303 can be operated in several modes, including combinations of these modes:

1. FollowMe

TM

Mode

Crosshead movement responds to pushing or pulling on the force gauge shaft or load cell.

Increasing force produces greater speeds. Useful for quick positioning during setup and sample loading/unloading.

2. Basic Mode

Manual control of crosshead motion.

3. 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.

4. 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.

5. 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.

6. 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.

7. Break Detection Mode

Crosshead stops when a sample break has been detected. An auto-return or cycle/dwell time sequence may follow.

8. PC Control Mode

Test stand is controlled through a USB connection with a PC.

The Operating Mode home screen appears as follows:

5.4 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:

1. Maintained

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 (default)

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, twist the button clockwise until it assumes its original position. To resume the test, press UP or DOWN.

23

Model ESM303 Test Stand

User’s Guide

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.

5.4.1 Travel Indication

If installed, the position is displayed in the upper left corner of the display. The unit of measurement is dictated by the UNITS feature. To zero the value, press the Zero Travel key. The position will be retained during power cycles.

5.4.2 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 on the left side of the test stand column, as shown in the image to the left. Adjust their positions by loosening the thumb screws, repositioning, and re-tightening the thumb screws.

5.4.3 Overload Protection

The available interface cable is required for overload protection of a Mark-10 force gauge or load cell. If overload protection is installed and enabled, the crosshead will stop when the programmed percentage of full scale of the instrument has been reached.

When overload protection is installed, if the cable is disconnected, and/or if the instrument is powered off, an error message will appear. Plug in the cable and/or turn on the instrument 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.

5.5 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 opposite 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 force set point, the limit condition may be overridden by pressing and holding UP or DOWN for two seconds.

5.6 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.

24

Model ESM303 Test Stand

User’s Guide

A cycling sequence can be initiated from any position and can start in either 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:

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.

5.6.1 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. Cancel the cycle sequence:

Press 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.

5.7 Preload Mode

In this mode, the crosshead moves at the set speed (up to 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 feature occurs. If the ZERO,GO setting is selected, and if the set speed is greater than 10 in/min [250 mm/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.

25

Model ESM303 Test Stand

Note 2:

Preload and Load Holding cannot be enabled simultaneously.

User’s Guide

5.8 Load Holding Mode

In this mode, the crosshead moves until the set point value programmed in the force gauge is reached.

The crosshead position dynamically adjusts to maintain a programmed force. The force gauge or load cell’s capacity should be as close as possible to the intended load, for best performance.

In the instrument, 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.

5.8.1 Adjusting speed for sample stiffness variations

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 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 minimally relaxing materials such as metal springs, the oscillation should stop shortly after the holding force is reached.

Load holding may be interrupted at any time by pressing STOP.

Note:

Preload and Load Holding cannot be enabled simultaneously.

5.9 Break Detection Mode

In this mode, the crosshead will stop when a sample break has occurred. This action occurs when the force decreases to a specified percentage of peak, as illustrated below:

10 MAINTENANCE AND SERVICE

User’s Guide

The ESM303 should be operated in a dry and clean area. Under these circumstances only a few periodic maintenance operations are required:

10.1 Ball screw lubrication

Periodic lubrication improves performance and increases the longevity of test stand components. On average, lubrication is recommended twice per year. However, the frequency should increase if the stand is operated in adverse environmental conditions, including airborne dust, temperature and humidity extremes, and other factors. Frequent test stand usage also necessitates more frequent lubrication.

Follow these instructions for proper ball screw lubrication:

1. Power off the test stand and disconnect all cables.

2. Remove the left sheet metal and electronics support plate as described in previous sections.

3. Using a brush, apply a small amount of general purpose bearing grease to the screw, as shown in the image below:

4. Cycle the crosshead up and down several times until the newly applied grease has been spread evenly over the length of the screw.

5. Re-install the hardware. Be sure to position the upper limit switch above the crosshead and the lower limit switch below the crosshead before installing to the electronics support plate.

10.2 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.

10.3 Check for loosened components – once per month

1. Remove the test sample from the test stand.

2. 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.

10.4 Removing and replacing the Electronics Support Plate
