SAUTER TVM-N Motorised Test Stands Instruction Manual

SAUTER TVM-N Motorised Test Stands

Introduction

The TVM-N test stand can measure tensile and compressive forces very accurately and is easy to operate. Various force measuring devices can be mounted on the test stand for the measurements.
SAUTER offers optional software and accessories to make the measuring system more versatile in use. Please contact SAUTER or the SAUTER supplier or visit our website www.sauter.eu.

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.

Possible applications

The TVM-N test stand has been 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 include, for example, infinitely variable speed adjustment, automatic up and down movement with preset repetitions (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) and can be conveniently controlled from there using a PC. This software is also able to document force-time and force-displacement. It is also possible to operate it only with an FH force gauge, because here the setting options of the FH force gauge 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..

Application

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.

Speed setting
The speed can be adjusted continuously up to the maximum. The set speed can be read off the display.

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

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. The test stand can be controlled at the connection for the force measuring device using an FH series force measuring device to prevent overload.

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.
