1. Caution on Safety

This detector is capable of detecting either load of the compression direction and tension direction. You are
free to install it to match your own machine. The tension detector is installed basically through the pillow
block to the roller which, of the guide rollers as shown in Fig.1, will become the vertex, and converts the
material tension into load for detection.
In this case, the load to be applied to the detector, as shown in Fig.1, will become the tension victor sum
and the weight of the tension detecting roller will be added thereto.
Fig. 1 An example of tension detector installation
In case the material is broad, two detectors are installed as each end of the tension detecting roller to ensure
correct detection of the tension over the entire width of the material even if the material is tensed on one
side only.
In case the material is narrow, only one detector is used on one side alone, making it possible to allow the
automatic aligning type bearing to hold the other end.

This product is a high sensitivity detector manufactured by precision processing and assembling technolo-
gy, and should be installed and handled with greatest care.
3.1 Installing cautions
WARNING Do not use the standard product in flammable or explosive atmosphere.
It may lead to an explosion if operated without using explosion-proof type and safety barrier.
Never use in flammable or explosive atmosphere with oil, grease, flammable gas or the like,
Use the intrinsic safety explosion-proof type together with our specified safety barrier.
WARNING Turn off the power source, and make sure the rotating element is stopped still.
Working while the power is supplied causes electric shock or injury. When mounting, dis-
mounting, adjusting, or servicing, turn off the power source of the device beforehand, and
make sure the rotating element is stopped still. At this time, be careful not to have the hand
or fingers caught in the moving or rotating parts.
WARNING Tighten and lock the bolts to specified torque completely.
Bolts may be sheared and broken to cause injury if not tightened sufficiently. Lock the bolts
with adhesive or spring washer to prevent form loosening securely.
WARNING Do not drop sawdust or wire chips into product.
Or it may lead to product damage, smoking, firing, or other danger.
CAUTION Do not suspend product by lead wire.
Or the lead wire may be broken, and the product may fall to cause injury.
Mount and dismount by holding the product directly.
3. Installation of tension detector

4
(1) Make sure to use a self-aligned type bearing so that imbalances in the tension detecting roller, defective
unevenness in the sensor mounting surface, other machining errors, length change of the roller due to
temperature change, etc. will not be detected as tension.
To minimize the tension detecting error at the same time, keep machining error to a minimum.
The recommended imbalance of the tension detecting roller is class G1 to G6.3 of ISO 1940-1 (1986)
(depending on machine specifications).
(2) When supporting the tension detecting roller at both ends,
adjust the height of the detector mounting surface.
- The asterisked (*) portion should be the minimized in
order to reduce tension detect on errors.
- If the asterisked (*) portion is large, the material may wind
improperly, the bearing life may become shorter, the out-
put at the zero point may fluctuate, or other defects may
occur.
- When using a spacer for adjusting the height, use a spac-
er having a shape capable of covering the entire mount-
ing surface
(3) The resultant force of tension due to material angle should be settled within the recommended resultant
force range in the drawing with respect to the hinge position in order to keep the precision of tension
detection.
(4) If the detector bolt is loosened by mistake, the original characteristic is not restored if tightened again.
(5) When mounting the detector, be careful not to apply large impact load or excessive load, or admit cutting
chips, screws or other foreign matter.
In particular, pay attention to the following points to avoid impact or excessive load when mounting.
1) If fixed without using self-aligned bearing, abnormal load is applied in the event of eccentricity
or defective parallelism.
2) When the pillow block or roller is directly hit by hammer in order to adjust the parallelism be-
tween rollers.
3) When there is any person or object on the detecting roller.
4) When machine is transported after mounting the detecting roller, and vibration or impact is ap-
plied during transportation.
5) When the tension detector is dropped or transported without cushioning material.
(6) If using in environments accompanied by large temperature changes, employ a mechanism for absorb-
ing length changes due to temperature changes of the tension detecting roller so as not to affect the ten-
sion detecting precision.

(7) In the case of low tension operation, minimize the mechanical loss to keep the tension control error to a
minimum.
(8) The tension detecting roller cannot be supported at one side.
(9) Install guide rollers before and after the tension detector so that material angles 1, 2 may not differ.
(10) When installing the roller, match the roller center and the center mark ( see outside dimensions ) of the
tension detector.
3.2 Mounting
Use bolts with strength of 10.9 or more specified in ISO 898-1 ( 1988 ).
(1) Detail of mounting of tension detector ( standard installing of LX-TD type ).
The pillow block fitting bolts should not be linger than the thickness “t” of the installing base of the detec-
tor side.

4.1 Caution for wiring
4.2 Connection between tension detector and controller.
(1) The drawing shows the connection in the case of tension vector direction applied in the compressive
direction.
When applied in the tensile direction, exchange the wiring of white and green.
(2) When extending the lead wire, use shielded wire.
5.1 Caution for operation
During operation of the detector, be careful not to apply large impact load or excessive load. Impact or ex-
cessive load may be caused in the following cases.
1) When the dynamic balance of roller is poor and abnormal vibration is caused due to resonance or
the like.
2) When accelerating or decelerating suddenly in the machine of large bobbin inertia.
3) When a winding shaft torque corresponding to maximum winding diameter is given by mistake in
the case of small winding diameter.
4) When the material has an uneven tension.
WARNING Do not drop sawdust or wire chips into product.
Or it may lead to product damage, smoking, firing, or other danger.
WARNING Do not touch the product during operation.
During rotation of the detecting roller or other parts, don’t touch the tension detector by hand,
finger, or other parts of the body, or you may have electric shock or injury. Protect the exposed
rotating and moving parts with cover to prevent from touching by hand or finger.
