Thank you for choosing our universal test stand FMT-310. Please read the entire operation manual

thoroughly before using this instrument for the first time. The information contained here will help you

to achieve accurate and reproducible results and to avoid misuse or damages.

This FMT-310 Force Tester is designed to apply material testing and to acquire load-displacement-

diagrams within fixed load and displacement limits. To control the fitness for use of the test stand for

your special case of use, get if necessary into contact with our technical service.

1.0 Safety Precautions

Please note, that the max. admissible force values of the load cell and of the linear

drive with step motor can be different.

The load cell can be damaged by an overload of the measuring axle. Do not apply

side or radial forces to the rigid measuring axle. Please note the advices during the

assembly of tools.

Operate the instrument in appropriate environments only. The instrument is

equipped with a temperature compensation for 0°….40°C. Use the instrument in

this temperature range only.

If you effect a material testing during which the material can break or sliver in a

way that people, the test stand or other instruments in the near could get

damaged, you have to install protective equipment. If you have no protective

equipment at your disposal, we would be glad to help you out.

2.0 Overview over the components and the initiation

The FMT-310 Force Tester consists of two base units, the motorised test stand (1) with integrated load

cell (2) and the control unit (3) with touchpanel (4) for the

operation. The dependence of the application area, different

tools can be assembled on the specimen stage (5) and /or

the axle of the load cell (6).

Please check that the load cell stands at any position

between the two limits (7) before initiating the instrument. If

this shouldn’t be the case, it is possible to displace the load

cell manually as long as the test stand is not switched on.

Attention! If the test stand gets initiated without

the load cell standing between the limits, it can

effect a damage of the linear unit.

Connect now the control unit with the test stand by inserting and

locking the 37-pol connector (11).

Check if the two plug connections (9;10) for the position sensor (8)

and the load cell are inserted.

Connect now the power cable (12)

and switch on the instrument. The

lamp within the switch gleams red

when the instrument gets energized.

Check if necessary if the emergency

stop switch is pressed.

3.0 Engaging the instrument and preparing the measurement.

After switching on the instrument at the main switch,

you can see the start picture in the display. At the same

time an automatic function test takes place and the

force gauge gets initiated. After this test has been

finished succesfully, the change to the main menu

takes place.

Press now the button REF, it takes place an

automatic adjustment of the internal zero

reference (machine-zero). For this the load

cell gets driven into the highest position. After the

reference path has been effected succesfully, the test

stand is ready for use. Now you can choose the

wanted function within the main menu.

In dependence of the application different tools get assembled on the measuring axle and onto the

specimen stage. In case that these tools have been assembled in factory, the limits (limit of way) are

already adjusted.

Attention! In case that you use your own tools and/or effect the initiation without the help of

our technical service, please effect an assimilation of the limits within the service menu to

avoid collisions and by this damages on the test stand.

5.0 Mode of operation

5.1 Explanation of instrumentation

5.1.1 Force measurement

For the force measurement, high-precision measuring beam get used, their deflection during force

transmission gets recorded by a extension-measuring tape. The conversion of the analog signals into

digital form takes places within the load cell. The digital signals of the D/A –converter constitutes 1000

Hz., the transfer rate to the control unit 100 Hz.

The load cell gets imported and tared with every restart of the universal testing machine.

Contemporaerly a temperature compensation takes place. Fluctuation of temperature during the

operation of the test stand lead to errors of measurement (TK=0,02%K). If more intense changes of the

environmental conditions take place during a working day, it is recommendable to switch on and off

again the instrument to adjust the load cell to the compensation of the changed environmental

conditions.

The load cell should be checked at regular intervals. Accordant to DIN ISO 75000 a calibration is

necessary after 12 month, after repairation or after lager backfittings. A change of the load cell, if it has

been effected duly, does not demand a calibration or adjusting.

The calibration (adjusting) of the load cell is simple user effectable within the service- program (see

chapter 6.2.).

5.1.2 Path measurement

The whole traverse path (405mm) of the drive gets suspended in 1.687.500 steps. This corresponds to

an intern resolution of 0,24µm, the change of the position in single steps gets indicated with a

resolution of 0,01mm. As both the load cell and the machine itself get expanded or compressed under

load, the absolute traverse deviates from the actual path on the measuring axle. To compensate this

error, the indicated path gets corrected with a force depending factor. Before the purchase of the

instrument, the correction factor gets appraised and setted by the manufacturer. The correction factor is

simple user appraisable and can be saved within the instrument.

A calibration (adjusting) should be effected after changing the force gauge as only theoratical values get

get adopted into the control unit during the initiation of the force gauge. The calibration takes place in

the service menu. (see chapter 6.2).

5.1.3 Disconnect conditions / Limits

Indipendent of the mechanical structur of the universal test stand and the force gauge, for which limits

get deposited before commissioning the instrument, it is possible to deposit universally valid limits for

path and force, as protection of checking tools and of material, which is to control. When these values

get achieved, the inspection process gets aborted and an infotext-display takes place in the lower line

of the display.

The load cells have an additional electronic overload protection which takes effect, independently of

the setted limits, as soon as a damage of the load cell is imminent. The control unit tries automatically

to take it off into the diametrical direction with a propulsion command.

Similarly the drive does not allow to cross the mechanical boarders which are predetermined by the

cursors, as they effect a emergency-stop.

Whenever an emergency-stop has been effected or the test stand does not allow any manual propulsion

because of overlapping limits, the test stand has to be turned currentless. In this condition the retention

force of the motor gets lifted and the load cell can be pushed to any position between the two cursors.

5.2. Manual mode

In the manual mode you can move the load cell

with a preselected speed within the

predetermined limits upwards or downwards by

pressing the appropriate buttons. The current

reading and the current running speed are

indicated on the screen.

5.2.1 Regulation of the speed levels

In the manual mode up to 5 different speed levels can be chosen by pressing the key V>. The speed

levels 1 to 5 can be regulated within the therefore intended submenus. The submenu gets called by

pressing the key Vset . Than you can choose the speed level you’d like to edit and enter the approriate

speed. When you leave the submenu, the speed levels get changed corrispondingly.

5.2.2 Regulation of the limits

The traverse path of the load cell can be limited

within the machine and load cell determined

maximum values. Therefore the submenu limits

gets called in which you can regulate the values

within the navigation bar.

Advice !

i The limits regulated for the manual mode have no influence within the test programs. The drive

gets stopped with a certain speed depending profile after achieving the limits or the Stop-signal by

pressing the stop-button or letting go the up-/down button. At maximum speed the lag can constitute

2mm.

5.2.3 Continous mode (Conti)

Within the continuous mode you can start the drive by pressing the up or down-button in the required

direction. The drive moves the load cell in the required direction till either the Stop-button gets pressed

or a limit gets achieved.

5.2.4 Ride in the Tipp-mode (Tipp)

In the tip-mode, which gets setted by the mode-button, the drive gets moved with a preselected speed

into the required direction, till the button gets released or a limit gets achieved.

5.2.5 Indication and reset of the peak values ( maximum values)

The absolut maximum values for traction force and compression force get saved within the load cell.

The two maximum values reached at last, get indicated after pressing the PEAK –button. The peak-

memory gets only canceled in the manual mode, when the reset-button is pressed, a test program gets

called, and a reference path has been effected or the construction was spent.

5.2.6 Tare the force and path indication

All indicated values can be reset to 0 during stillstand of the drive. Thereby the internal data of the load

cell and absolute position of the linear unit do not get tared. Therefore a reference path has to be

effected.

5.3. Automatical mode with predefined inspection processes

5.3.1 general

With inspection process are ment motion sequences (program steps) which get effected typically for a

test. Every inspection process can include up to 30 single steps. It’s possible to save a total of 16

inspection processes within the control unit, as standard 8 inspection processes are deposited.

In every inspection process various parameter for a test program can be insert individuelly to effect

adjustments on the material, which has to be checked and tools in use. For every inspection process it

is possible to deposite up to 8 different parameter sets as test programms.

As maximum up to 128 parameterized test programms can be deposited within the control unit.

The parameter have to be insert for every test programm in dependence of th load cell in use, the tools

in use and the respective test object. First of all, reasonable values for a test get usually averaged out

within the manual mode. While changing the load cell all parameter sets in all test programms get reset

onto the default values to avoid possible damage on the construction. If you change the tools in use or

the material to check, it might be necessary to adjust the parameter to avoid damages on the

construction.

The submenu to regular the parameter gets called by pressing the parameter button.

5.3.2. Definition of the valve position

Reference position absolut position in which the load cell gets driven during the referencing of the

drive. (Masch.null). All other position refer to this absolut set point.

Setpoint TOP Absolut upper position in which the load cell can be driven during the operation.

As maximum this position comes up to the reference position. (Default =

0,00mm)

Setpoint DOWN Absolut low position in which the load cell can be driven. As maximum this

position comes up to the maximum traverse pathof the drive. (Default =

405,00mm)

HOME position Absolute position in which the load cell gets driven before and after a test rum to

have the possibility to in insert the test object.

Position START Absolute position in which the load cell gets driven before a test run starts. Unit

drives from the HOME position into the START position.

Zero-position Relative position in which the measurment of length gets tared in dependence of

other measures (0-point of measurment)

5.3.3 Predefined functions

Some propulsion commands or subroutines, which again and again are necessary are deposited as

functionsblocks.
