Operating procedure

• Have you read and understood the Operating Instructions, in particular, Chapter 1 “Warranty and Liability”? You are not permitted to operate the device before doing so.
• Before working with the device you must put on your personal protective clothing, if necessary. For example, eye protectors, gloves, etc.
• The ID plate with the CE mark and the serial number as well as the calibration label (optional) and the SCHMIDT Quality Seal are provided on the surface of the instrument.
• Switch on the instrument as described in chapter 3.21.
• Instrument settings as described in chapter 3.3.
• Select a material characteristic curve (chapter 3.3) or generate a new adjustment (chapter 3.4)
• Allow approx. 10 minutes for thermal stabilization of the instrument.
• Thread the process material through the measuring and guide rollers, following the red material path symbol on the front of the sensor.
• The measured tension can be read in the display.

Damping

Feature to be used for tensions that vary strongly

• In the “Damping” submenu, a damping factor can be selected for each material characteristic curve. In the “Display damping” menu, the damping factor of the currently selected material characteristic curve is displayed.
• This can be changed in the “Display damping” menu without changing the setting in the material characteristic curve.
• To use the damping factor assigned to the material characteristic curve again, this must be set in the “Display damping” menu or the material characteristic curve must be selected again.
• The factory setting for the damping factor is 5. The average shown on the display is calculated as follows.

Using the alarm function

Requirements:

• A min. and max. limit value must be set in the “Material selection” menu for the material characteristic curve with which a measurement is to be conducted.
• Furthermore, the alarm must be activated in the “Material selection” menu.
• In addition, the alarm must be activated in the “Alarm” menu.

Changing the settings

Channel selection

• You can connect up to 24 display units by cable to the RS-422-to-RS-232 converter and onto a PC. The individual display units are distinguished by different channel numbers (chan), which can be assigned sequentially as shown in Fig. 3.4.3a, or random order as shown in Fig. 3.4.3b. If you connect more than one display unit, the lowest channel number (chan) assigned must always be 01, as shown in Fig. 3.4.3a and fig. 3.4.3b.
• If you connect only one display unit, this unit must be assigned the channel number 00, as shown in Fig. 3.4.3c.

Sensor calibration

• All tension meters are calibrated with standard materials – such as polyamide monofilament (PA) – according to the SCHMIDT factory procedure; the material path is vertical. The corresponding diameter and material can be found in Chapter 2 of the sensor.
• In the case of factory adjustment to the customer’s sample, the procedure is the same. In this case, however, the adjustment to the SCHMIDT sample is omitted. Any difference in process material size and rigidity from the standard material may cause a deviation in the accuracy. In 95% of all industrial applications, the SCHMIDT calibration has been proven to provide the best results and is used for comparative purposes.
• If required you can also operate the sensor with a material path other than vertical. Should the process material differ significantly from the SCHMIDT calibration material in size, rigidity, or shape, we recommend special calibration using customer-supplied material. If a different material path (e.g. horizontal) or special calibration using customer-supplied material is required, you need to carry out static zero and gain adjustment as described in Chapter 3.5.1.
• Since zero and gain adjustments are always performed statically, the readings may differ under dynamic load.

Zero and gain adjustment

• You can save up to three different calibrations.
• The instrument is factory-set to material characteristic curve 1.
• This is the factory calibration, which should not be overwritten.

Requirements:

• Two weights, one corresponding to 10% and one to 90% of the selected tension range, must be provided. Pay attention to the selected unit of measure (cN or kg).
• Sensor installed at measuring location.
• The instrument is switched on as described in chapter 3.2.1.
• Allow approx. 10 minutes for thermal stabilization of the instrument.
• The desired material characteristic is selected according to chapter 3.3

Zero adjustment:

• Thread the process material through the measuring and guide rollers, following the red material path symbol on the front of the sensor.
• Hang a weight that corresponds to e.g. 10% of the tension range (pay attention to the correct unit of measure) from the process material, vertically, as shown in Fig. 3.4.1.(Always use a fresh portion of the material to be measured.)
• Press and hold the key.
• Press the key repeatedly until the tension value on the LCD is equal to the value of the suspended weight.
• For example Sensor model TS1-200
• Weight 20 cN =
• TFT display
• Release the key.
• The set value is saved to the calibration curve after approx. 20 seconds and the instrument changes back to measuring mode.
• The zero adjustment values are only saved permanently in the SC-PM memory after approx. 20 seconds. Therefore the unit must not separated directly from the power supply.

Gain adjustment

Requirement:

• Zero adjustment was carried out.

To carry out gain adjustment:

• Thread the process material through the measuring and guide rollers, following the red material path symbol on the front of the sensor.
• Hang a weight that corresponds to e.g. 90% of the tension range (pay attention to the correct unit of measure) from the process material, vertically, as shown in Fig. 3.5.1.
• (Always use a fresh portion of the material to be measured.)
• Press and hold the key.
• Press the key repeatedly until the tension value on the LCD is equal to the value of the suspended weight.
• For example Sensor model TS1-200
• Weight 180 cN = Display
• Release the key.
• The set value is saved to the calibration curve after approx. 20 seconds and the instrument changes back to measuring mode.
• The gain adjustment values are only saved permanently in the SC-PM memory after approx. 20 seconds. Therefore the unit must not separated directly from the power supply.
• Check the adjustments with a fresh portion of the process material and repeat the procedure if necessary.

Interfaces

Analog interface

• The analog interface is provided for customer signal processing or for connecting a line recorder which conforms to the current industrial standard.
• Please refer to Chapter 2.1 for the specifications.
• CAUTION – The analog interface must be calibrated only by qualified electrical personnel.

Gain adjustment of the analog interface

Requirements

• Connect a volt meter (ampere meter with Code A3) to the analog interface.
• Switch on the instrument as described in chapter 3.2.1.
• Allow approx. 10 minutes for thermal stabilization of the instrument.
• Thread the process material through the measuring and guide rollers.

Adjustment:

• Select the “Analog adjustment” menu item (chapter 3.1)
• Press the or key repeatedly until the display of the volt meter connected to the analog interface reads 10.0 volts (20 mA with ampere meter).
• Check the setting and repeat the procedure if necessary.
• Save the adjusted values and exit the menu by pressing
• CAUTION – The analog interface must be calibrated only by qualified electrical personnel.

Digital interface

• The »Tension Inspect 3« program
• The »Tension Inspect 3« Software from SCHMIDT is described in a separate user manual.

Windows terminal program

• The measured values can be transmitted to a personal computer.
• You can connect the computer to the SC-PM by using the RS-422 / RS-232 converter which is available as an accessory.

Requirement:

• A communication program, such as Terminal or HyperTerminal (provided on
• MS Windows Version 3.0 or later), must be installed and configured on the computer.
