1 Introduction
The TVO-S and THM-S test bench series has a stepper motor. With this motor an
exact positioning as well as a uniform movement can be realized. A further advantage
of this technology is that the full force is available from zero even at low speeds.
Stopping is also carried out very precisely and without overtravel.
All Sauter force gauges up to 2 KN, depending on the test bench, can be adapted to
the TVO-S and THM-S series.
SAUTER offers optional software and accessories to give you the greatest possible
flexibility in configuring your measuring system. Please contact SAUTER for further
information.

4 Check before use
After receipt of the test bench, it should be checked in advance whether no transport
damage has occurred, whether the outer packaging, the metal housing, other parts
or even the test bench itself have been damaged. If any damage is evident, please
notify SAUTER GmbH immediately.
5 Possible applications
The TVO or THM test stand is designed to accommodate most SAUTER force
measuring devices without any great difficulty. It has a wide range of applications and
can be operated manually. It can also perform individual functions independently.
These are, for example, infinitely variable speed adjustment, automatic horizontal
movement (THM) and vertical movement (TVO) with preset repetition (up to 1000
cycles). It can be used for material testing in the metal, plastics and textile industries.
It can also be operated with SAUTER software (AFH), from where it can be
conveniently controlled by PC. This software is also able to document force, time and
distance. Operation with safety STOP is only possible with an FH force gauge,
because here the setting options can be used, for example to protect the test stand
from overload with the STOP value.
•Choose the right test stand with regard to the maximum force you require.
Adjust the force gauge used to the maximum force or take special care when
setting the travel distance. (Possible destruction of the force gauge)
•Under no circumstances should you attempt to open, repair or modify the unit.
Contact SAUTER GmbH.
•The test bench is not suitable for operation in a humid environment. Avoid
penetration of moisture into the housing under all circumstances.
•Do not use sharp objects to operate the buttons.
•Use the limiting rings on the test bench to check the travel. Precise adjustment
of the travel using the limiting rings prevents damage to the test stand and the
force gauge used.
•From time to time, moisten the rods with a lubricating oil.
Turn off the unit and unplug the power cord if you are not going to use it for a long
time.

The movement of the test bench is defined by the lower and upper limiting ring.
These limiting rings must be adjusted for each test.

7 Application
7.1 Check before starting the measurement / test
•Wiring, switching on Display flashes 5 times
•Test the movement without the test piece, manually actuating the limit
switches to test their function.
•Test of the automatic movement. Press the Manual/Auto Mode button, Auto
Mode indicator lights up. Set cycles (avoid setting "1"), start test run with Up or
Down button. At the end of the cycles, the test bench stops and emits an
alarm tone 3 times, test finished.
7.2 Speed setting
The speed can be adjusted continuously up to the maximum. The set speed can be
read off the display.
7.3 Presettable cycles
A number of cycles can be preset on the test bench. The preset value is displayed in
the lower area. It can be set with the keys Counter , Counter and Select
counter position. The "run" number is displayed in the upper area. The counter can
be reset with the Zero key.
7.4 RS 232 connection
The test stand has two 9-pin connectors to connect a force gauge and one connector
for communication with the PC. The test stand can be operated with SAUTER AFH
software. This allows the motion control and number of cycles to be set directly on
the PC. The software can be used to evaluate the data in terms of force-time or
force-displacement. At the force gauge connection, the test stand can be controlled
with an FH Series force gauge to prevent overload (using the Stop parameter on the
FH Series force gauge).
7.5 Limit switch
In manual mode, movement stops when the limit switches are reached. In Automatic
mode, movement stops at the Perimeter Switch for about 5 seconds and then
continues in the opposite direction. In order to ensure that the test/examinations run
smoothly, you should ensure that you align the boundary rings very precisely so that
the test object or test equipment is not destroyed if the path is too long/short.

8 Warnings
Incorrectly performed force measurements can lead to serious injury to persons and
damage to objects. Force measurements should therefore only be carried out by
trained and experienced personnel.
In particular, it should be avoided that forces are applied to the measuring instrument
by the test bench which exceed the maximum load (Max) of the test bench or
measuring instrument or which do not act axially on the instrument via the test bench
