The requirements of the CE specification are only complied with if the tension sensor is equipped and operated with display units and connecting cables supplied by HANS SCHMIDT & Co GmbH. Certification to the CE specification does not extend to, and shall be invalid for any other combination. Under no circumstances shall HANS SCHMIDT & Co GmbH be held liable for any damage resulting from the use of non-SCHMIDT sensors or cables.

2.5 Delivery Includes Sensor 1 Operating Instruction
2.6 Unpacking Unpack the instrument and inspect it for any shipping damage. Notices of defect must be announced immediately, in writing, at the latest within 7 days on receipt of the goods.
3 Operating Procedure Tensions that exceed the tension range of the instrument by more than 100% may cause permanent damage to the measuring spring and must be avoided under any circumstances.
CE conformity testing was carried out and successfully passed by Hans Schmidt & Co GmbH with a complete unit consisting of: TS sensor, SCD-1 display unit and an 5 m long connecting cable (special cable).
In no event shall HANS SCHMIDT & Co GmbH take over any warranty coverage for, or shall be held liable for, any damage resulting from self-made cables.
The model number, the serial number, the calibration label (option) and the SCHMIDT Quality Seal are provided on the cylindrical portion of the sensor.

3.1 Initial Setup – Install the sensor at the desired measuring location. For mounting sensor model TSW at least 8 screws (front plate) had to be used. – Connect the sensor to the supplied or existing display unit. The pin assignment of the 8-pin connector located on the rear side of the sensor is described in Chapter 2.3 – If the material path is other than vertical or if the process material deviates significantly from the SCHMIDT calibration material, you need to carry out zero adjustment and gain adjustment as described in Chapters 3.2.1 and 3.2.2 before starting measurement. – Allow approx. 10 minutes for thermal stabilization of the sensor. – Thread the process material through the measuring and guide rollers, following the material path symbol on the front of the sensor.
3.2 Internal Adjustment of the Sensors
General information: If the sensor has been delivered with a display unit, the ZERO and GAIN adjustments should only be carried out with the supplied display unit. All tension meters are calibrated with standard materials – such as polyamide monofilament (PA) – according to the SCHMIDT factory procedure; the material path is vertical (TSB2 horizontal). Any difference in process material size and rigidity from the standard material may cause a deviation of 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 sensors with a material path other than vertical (TSB2 horizontal). 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 the material path is other than vertical or if the process material deviates significantly from the SCHMIDT calibration material, you need to carry out static ZERO and GAIN adjustment as described in Chapters 3.2.1 and 3.2.2.

– Install the sensor in the desired position at the measuring location using the provided mounting holes. 13
3.2.1 ZERO Adjustment (Cont.) – Screw the countersunk bolts (M2.5) labelled ZERO and GAIN all the way out on the rear side of the sensor. – Allow approx. 10 minutes for thermal stabilization of the sensor. – Thread the process material through the measuring and guide rollers, following the material path symbol on the front of the sensor.
When threading the process material through the rollers, follow the material path symbol on the front of the sensor. If a force is applied to the middle sensor roller in the incorrect direction, damage could result.
Since ZERO and GAIN adjustments are always performed statically, the readings may differ under dynamic load.
– Hang a weight that corresponds to e.g. 10 % of the tension range from the process material.
– Connect a volt meter to pins 1 and 7 of the connector on the rear side of the unit. – Adjust the potentiometer, which you can reach through the ZERO hole in the housing,
with a screwdriver (with a point width of max. 1.9 mm) until the display of the connected volt meter reads, for example: Sensor model TS1-200: Weight 20 cN = Display 0.100 V for the TS standard version or Weight 20 cN = Display 1.00 V for the TS version with 10 V output signal.
Do not insert the screwdriver at an angle as this may damage the potentiometer. Zero adjustment of sensors with output signal Code A10 has to be realized with display unit SC-PM
3.2.2 GAIN Adjustment
Requirement: ZERO adjustment carried out. Thread the process material through the measuring and guide rollers, following the material path symbol on the front of the sensor.
– Hang a weight that corresponds to e.g. 95% of the tension range from the process material.
– Adjust the potentiometer, which you can reach through the GAIN hole in the housing, with a screwdriver (with a point width of max. 1.9 mm) until the display of the connected volt meter reads, for example: Sensor model TS1-200: Weight 190 cN = Display 0.950 V for TS standard version or Weight 190 cN = Display 9.50 V for TS version with 10 V output signal.
– Check the adjustments with a new filament of the process material and repeat the procedure, if required, as described in Chapters 3.2.1 and 3.2.2.
– Screw the ZERO and GAIN countersunk bolts back in on the rear side of the sensor.
Do not insert the screwdriver at an angle as this may damage the potentiometer. Gain adjustment of sensors with output signal Code A10 has to be realized with display unit.

4 Service and Maintenance The tension meter is easy to maintain. Depending on operating time and load, the instrument should be checked according to the locally valid regulations and conditions (as described in Chapter 3.3). The use of other test methods than the procedure described in Chapter 3.3 may cause deviating measuring results.
4.1 Rollers You should regularly inspect the rollers to assure that they are running easily and smoothly. You can replace the rollers yourself, as necessary. Please indicate the tension meter model and the serial number in your spare-parts order.
5 Cleaning For cleaning the unit, do not use any AGGRESSIVE SOLVENTS such as trichloroethylene or similar chemicals. NO WARRANTY OR LIABILITY shall be accepted for damage resulting from improper cleaning.
6 Verification Interval The question of finding the right frequency of calibration accuracy verification depends on several different factors: Operating time and load of the SCHMIDT tension meter Tolerance band defined by the customer Changes to the tolerance band compared to previous calibrations Therefore, the interval between verifications of calibration must be determined by the user`s Quality Assurance Department, based on the user`s experience. Assuming normal operating time and load as well as careful handling of the tension meter, we recommend a verification interval of one year.

7 Correspondence Should you have any questions regarding the instrument or Operating Instructions, or their use, please indicate above all the following details which are given on the ID plate: 1) Model 2) Serial number
8 Repairs Shipping instructions: We kindly ask for return free of charge for us, if possible by airmail parcel. All occurring charges, if any (such as freight, customs clearance, duty etc.), will be billed to customer. For return from foreign countries, we ask you to include a proforma invoice with a low value for customs clearance only, e.g. 50 Euro, each and to advise the shipment in advance by fax or eMail.
To avoid unnecessary follow-up questions, and the resulting loss of time or possible misunderstandings, please return the instrument with a detailed fault description to our service department. Please indicate in your order whether you require an Inspection Certificate 3.1 according to DIN EN 10204.
