PR-DTC-3000 Type
(Carefully read the following before using the unit)
The“PR-DTC-3000 Type”Tension Controller is a semi-automatic tension control device in the voltage controlled
OPEN-LOOP method. This method presets the starting voltage and the potential gradient of the controller
beforehand, and it calculates current voltage by deducting (Unwinding) or adding (Rewinding) the potential
gradient from or to the starting voltage per every revolution of the spindle. (A revolution detecting proximity sensor
is mounted at the spindle).
The calculated result transmits the output voltage in the range of 0~24V to the load device, that is, POWDER
CLUTCH/BRAKE.
( At the ratio setting section, you may set the number of revolutions per increase/decrease of the potential
gradient.)
Check whether there is any defect in the product and it matches with the packing list.
For the optimal performance and safe use of the product, make sure you have completely understood the
followings before use.
In particular, the product should not be employed for any other purpose than its intended use, and should not be
discretionarily remodeled.
Features of the Product
1) The tension can be controlled by simple adjustment and operation
● The tension can be controlled by setting only the variable voltage, number of revolution and starting voltage.
● A power failure compensation function of remembering the number of revolutions and output value even
when the power goes out.
2) Convenient to use
● Having adopted 3.2 inch Full Color TFT LCD, it provides diverse information such as product movements and
setup, and work progress rate.
● Value setup by operating a dial.
● Fabric data (starting voltage, number of revolutions and variable voltage) can be stored up to maximum 10
kinds. (data 0 to 9)
3) Addition of functions
● Proximity sensors of both PNP and NPN types can be used. (to be selected in SETUP)
● Weak excitation voltage can be set in accordance with the characteristics of Power Brake and Clutch.
● Basic parameters can be changed without entering SETUP mode. (start value, changed value and number of
revolutions)
4) Perfect for the following applications
● Where no precision tension control is required.
● Where the tension detector cannot be attached.
● Where manual calibration is not recommended.
● Where the system is composed of reasonably-priced components.
5) Materials applicable for the controller
● Printing, screen printing
● Packaging, filling, pasting, painting
● Cleaning, drying, fabric, sewing, coloring
Features of the product and Precautions

Taper Tension Controller
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.

Proximity sensor connecting terminal
※ To attain the perfect compatibility with the controller, make sure to use the cylinder-type proximity sensor by Autonics.
(And also, the 24V NPN or PNP type sensor)
Due to the potential risks of malfunctioning and damages to the unit, make sure to check the above
terminals and match their respective colors.
Precaution : Check the sensor connecting terminals
- Use crimp-style terminals being equal the figure below in size.
- Be sure to fasten terminals tightly so that they would not be a cause of malfunctions.
- Do not install input/output wires through the same duct with other power lines, and do not bind them together.
- The pulse input wire to the roller shaft should be grounded using a shield wire from signal receiver.

PR-DTC-3000 Type
The unit can be seriously damaged by the wrong connection (observe the diagram of load connection) of the power
terminal, contacts between the DC input/output wiring and power line, and the short circuit of the output line.
Before supplying power, ensure the appropriate connection between power and grounding, and the input/output wiring.
Precaution : Check power input and wiring
1) Output ON/OFF (OUT Input Terminal)
-
When the Remote Out is On, the control output is generated irrespective of [Out ON/OFF Button] on the panel.
- When the Remote Out if Off, the [Output ON/OFF Button] on the panel becomes valid, and each time the
button is pressed, the control output changes ON → OFF → ON.
2) Diameter Preset (RSD Input Terminal)
- As the initial diameter set when the Remote RSD is On is preset as the reel diameter, the measurement of the
reel diameter becomes initialized.
3) Unwind/Rewind (BWD Input Terminal)
- When the Remote BWD is On, the diameter measurement does Rewind to add diameter.
- When the Remote BWD if Off, the diameter measurement does Unwind to subtract diameter.
4) Emergency Stop (STP Input Terminal)
- When the Remote STP is On, the rate set at the STP is produced in proportion to the immediately preceding
output.
5) Calculation of the Diameter
- The unit always calculates the diameter based on the signals from the proximity switch.
- Based on the calculation, the control output adds at Rewind, and subtracts at Unwind.
