2.0 O PERATION
2.1 First Installation
1. Install the sensor at the desired measuring location.
2. Connect the sensor with 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 section 4.0.
3. If the material path is other than vertical or if the process material deviates
significantly from the factory calibration material, you have to carry out
zero and gain adjustment, as described in
section 2.3 adn 2.4 , before
first installation.
3. Wait approx.10 minutes for the sensor to warm up.
4. Thread the process material through the measuring
rollers, following the thread acquisition symbol on
the front of the sensor.
2.2 Internal Sensor Calibration
General Notes:
If the sensor was delivered together with a display unit, ZERO and GAIN
adjustment should only be performed on the supplied display unit.
All tension meters are calibrated with standard materials—such as polyamide-
monofilament (PA)—according to the factory procedure; the material path is
vertical (Model BTMS 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 factory calibration has been proven
to provide the best results and is used for comparative purposes.
If required, you can operate the sensors with a material path other than
vertical.
If the process material differ significantly in size, rigidity and shape we recom-
mend special calibration using customer material. In the case of a material path
other than vertical or special calibration using customer material you have to
carry out static zero and gain adjustment once again as described i
n Chapters
3.2.1 and 3.2.2.
The device must not be operated in explosion hazard areas and must not come
into contact with aggressive substances.
To avoid damage, do not move the center roller by hand.
Tensions that exceed the tension range of the device by more than 100%
may cause a permanent deformation of the measuring spring and must be
avoided under any circumstances.
