Features of the product and Precautions
Precautions for Installation
- Maintain the right vertical and horizontal angles of the product for installation.
- Install the product in a place devoid of vibration, shock, high temperature or humidity, direct sunlight, much
dust,or air containing much salt or ions.
- Do not install the product within the vicinity of inflammable gases or steam or dust.
- Wire the product as provided in the following drawings and check if all cables are properly connected.
- Ensure the earthing terminal is correctly grounded.
- Ensure the product is detached from the power supply cables or the cables with much electrical noise.
Precautions for Use
- Unwarranted operation of the controller may cause the defects of the object materials.
- Pora shall NOT be responsible for any damages to the controller caused by such operations.
Warning
For the installation and wiring of the controller, completely isolate it from the external power
supply. Failure to do so may result in an electrical shock or damage to the controller.
Precaution
Check the surrounding environment. Do not install the controller where it can be exposed to
excessive dust, conductive dust, corrosive gases, high temperature or rainy wind. It also should
not be installed in the places susceptible to vibrations or shocks. Failure to do so may result in
damages to, or malfunctioning or lowered performance of the controller.
Warning
Use anti-explosive products where there are high risks of inflammation or explosion. Failure to
do so may result in a fire or explosion. Use the anti-explosive products suitable to the given
conditions.

Connection terminals of the pickup-type tension detector have different colors from ones of the load cell
type tension detector. Because there may be a risk of malfunctions and damages, be sure to connect
them after checking a type of the tension detector and its connection terminals above.
Caution : Check of connected terminals for each type of the tension detector
If a tension detector is used for only one side,
connect between [2] and [6], [1] and [5] terminals.
Use of only one side of a tension detector

5. Alarm List
Up to recent 4 alarms are stored in the alarm history, and they are stored as Pr No. 35→36→37→38 in order
according to their occurred sequence (the latest alarm is 35, and the last alarm of no. 38 is deleted when a
new alarm is generated.)
When pressing any key in the alarm indication, it would return to the previous state.
AL 01 and AL 02 are not recorded in the alarm history of Pr No. 35~38.
1) Storing of Alarms (Item 35, 36, 37 and 38 of the Parameter Menu)
Excessive input alarm is indicated when too much load (above about 1.5 times of the rated load) is applied
to the tension detector, and if it is used under this condition, it may be a cause of the tension detector’s
damage. When the excessive input alarm is indicated no matter the item no. 05 (Pr No. 05) of the parameter
menu is set as [0] or [1], be sure to use after removing the cause of the excessive input alarm.
Caution : Check of the excessive input alarm
Alarm No. Alarm Information Details
AL 01 Excessive input
of the left detector
It is a monitor indication mode, which the input voltage of the left detector is
exceeded.
AL 02 Excessive input
of the right detector
It is a monitor indication mode, which the input voltage of the right detector is
exceeded.
AL 03 Excessive zero input
voltage range The input voltage range is exceeded when controlling the zero
AL 04 Unbalance of the zero
control voltage
Unbalance of the left and right detectors’ voltage is exceeded above 30% when
controlling the zero.
AL 05 Insufficient span load
of the left detector
The left detector’s input voltage is lacked to fail to control the span when controlling
the span.
AL 06 Insufficient span load
of the right detector
The right detector’s input voltage is lacked to fail to control the span when
controlling the span.
AL 07 Excessive span load
of the left detector The left detector’s input voltage is exceeded when controlling the span.
AL 08 Excessive span load
of the right detector The right detector’s input voltage is exceeded when controlling the span.
AL 09 Unbalance
of the span load
Unbalance of the left and right detectors’ sensed loads is exceeded above 30%
when controlling the span.

Sample installation
The tension detector employs two detecting rollers, with one located in either side, so as to successfully measure
even wide-bodied object materials which tend to slant to one side.
One tension detector suffices to properly measure the tension of the object materials that do not incline toward
one side.
For electric wires or ropes, a pulley is installed on one sensor to detect tension.

left tension detector
When controlling
an offset of the
right tension detector
After completing to control the zero and the span, the following items are set in the tension calibration mode,

setting value is flashed.)
- Press the [▲] or [▼] key to change into the desired setting value.
- When pressing the [ENTER] key, the entered value is stored.
- Press the [DISP] key to return to the ‘Tension Monitor Mode.’
(2) Span Control
It multiplies the indicated value of the left or right detector by a coefficient.
- In the tension calibration mode, press the [▲] or [▼] key, select one or the other of the ‘DISP SPAN
LEFT’ (left detector,) ‘DISP SPAN RIGHT’ (right detector,) press the [ENTER] key, and select an item (the
setting value is flashed.)
