Precautions for Use
Thank you very much for purchasing our product.
Please be sure to observe the following precautions when installing andoperating this unit.
(1) Do not use with power voltage ratings other than the specified voltage.
Connecting to voltage sources that are higher than the specified voltage isvery dangerous and could cause a fire.
Always check the power-supply voltage when wiring.
(2) Be sure to connect a power supply to the designated terminal.
The wrong connection could cause this unit to malfunction.
(3) For models fitted with an earth terminal, be sure to use D-class grounding
with ground resistance of 100 Ω or less (former Type 3 grounding).
Failure to do so could result in electrical shock when touching the housing
for this unit.
(4) Only qualified electricians are allowed to perform the wiring work.
(5) Only explosion-proof models can be used in explosion-proof areas.
(6) The power connection for this unit has a "" symbol on it.
Be careful when applying current because touching this connection could
result in electrical shock.
(7) Do not disassemble this unit; doing so could result in electrical shock.
(8) Exposure to combustible materials, liquids, and metals could result in themalfunction of this unit.
(9) Always install a safety device for a machine that may cause a serious lossof human life or equipment due to the malfunction of this unit.
(10) In the event of an abnormality, such as an unusual odor or smoke fromthis unit, turn off the unit immediately and contact our Service Department.

<Features>● The panel-mounted unit is significantly downsized compared to conventional models.
● Both LS- and LA-series tension detectors can be connected.
● The auto zero and auto scale functions enable adjustments with a single touch of abutton.
● Left and right tension signals can be output respectively as well as the total (2 types).
● Either the voltage output or the current output can be selected for output. The
response frequency is also user-selectable.

Perform a coarse zero adjustment only when an LA-type
tension detector is used. It is not required for LS-type tension
detectors.
LA-type tension detectors have coarse zero adjustment control knobs thatmove the zero point significantly. Be sure to perform a coarse zero adjustment
in advance before performing a zero adjustment to bring the tension value close
to zero.
First of all, manipulate the setting item "Pn00" to initialize the electronic volume
control.

Hang a weight on the tension detection roller using a heavy-duty tape or rope.
Make sure that the weight hanging on the tension detection roller and therollers located above and below it are on the same path as the sheet. The
weight that is used should preferably be equivalent to the normal tension. If aweight cannot be hung, use a spring balance instead.

Fn04 [Auto-scale capacity setting]: Set this item during calibration.
During a scale adjustment, set the value of the tension that is hung.

[Scale adjustment target values]
The target values for the left and right sides vary depending on thevalue of the [Fn04] auto-scale capacity setting and the style of useof the detector. For example, if a weight of 100 N is hung, set Fn04
to "100".
Both-end both-side detection: Half the value of [Fn04] ・・・・ Target
value is 50 N
Both-end one-side detection: Half the value of [Fn04] ・・・・ Target

[If the displayed tension does not reach the target value]
If the displayed tension moves close to but does not reach thetarget value during the scale adjustment, then the amplifier gain is
insufficient. Increase the [Pn01] gain changeover switch setting by
one. Also note that changing the [Pn01] setting moves the zero
point. In such a case, perform a zero adjustment again.
