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.

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:
• TSR 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.

INFO: The model number, the serial number, the calibration label (option) and the SCHMIDT Quality Seal are provided on the cylindrical portion of the sensor.

Mounting possibilities
Sensors FSR can be mounted in different ways:

• Mounting by using the frontplate on a cylindrical hole (cut out 38.5 – 40 mm Ø)
• Mounting on a flat platform

Initial setup

• If the sensor is delivered with the standard roller, it is already mounted in the factory.
  If the device is supplied with a roller code F, FB, R1, B6, or B10, it must be installed. Tight the cap nut with 1 Nm.

• Install the sensor at the desired measuring location using the 4 provided mounting holes. To avoid damage to the load cell, the transmission of force has to occur in the direction of the arrow. The direction of force is the angle bisector (fig.3.2).

• 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 adjustments and gain adjustments as described in chapters 3.4.1 and 3.4.2 before starting measurement.

• Allow approx. 10 minutes for thermal stabilization of the sensor.

• Thread the process material through the measuring roller, following the arrow on the front of the sensor.

Determining the tension range

The tension range can be calculated for every wrapping angle with this formula:

WARNING: When selecting the nominal measurement force it is necessary to take into account the weight of the guide roll and raise the nominal load respectively, particularly when working with small nominal forces.

Internal adjustment of the sensors

General information
All tension meters are calibrated with standard materials – such as polyamide monofilament (PA) – according to the SCHMIDT factory procedure; therefore the wraping angle is 180°.

WARNING: In any case you need to carry out static zero and gain adjustment as described in chapters 3.4.1 and 3.4.2.

Zero adjustment

• Install the sensor in the desired position at the measuring location using the provided mounting holes.
• Allow approx. 10 minutes for thermal stabilization of the sensor.

INFO: Since zero and gain adjustments are always performed statically, the readings may differ under dynamic load.

• Connect a volt meter to the yellow and green leads of the connecting cable
• 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 0 cN = display 0 V,

WARNING: Do not insert the screwdriver at an angle as this may damage the potentiometer.

Gain adjustment
Requirement: Zero adjustments carried out. Thread the process material in the measuring roller

• Hang a weight that corresponds 100% 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 FSR – 20N:
  Weight 20 N = Displays 1 V for FSR standard version or
  Weight 20 N = Displays 100 V for FSR 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 3.4.1 and 3.4.2.

WARNING: 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 the display unit.

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 3.4). The use of other test methods than the procedure described in Chapter 3.4 may cause deviating measuring results.

Rollers
You should regularly inspect the rollers to ensure 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.

Cleaning

For cleaning the unit, do not use any

INFO: AGGRESSIVE SOLVENTS such as trichloroethylene or similar chemicals.
INFO: NO WARRANTY OR LIABILITY shall be accepted for damage resulting from improper cleaning.

Verification interval

The question of finding the right frequency of calibration accuracy verification depends on several different factors:

• Operating time and a load of the SCHMIDT tension meter
• The 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.

Correspondence

Should you have any questions regarding the instrument or instruction manual or their use, please indicate above all the following details which are given on the ID plate:

1. Model
2. Serial number

Repairs

Shipping instructions
We kindly ask for a 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 the customer. For returns 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.

INFO: 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.
