PR-DTC-4000C
PR-DTC-4000CP
PR-DTC-4000C/4000CP is Digital Tension Controller, a model which controls the powder brake or the
powder clutch after reading the load cell, pickup sensor values.
The output includes 0 to 24 V which controls the powder brake or the powder clutch, and 0 to 10 V, 4 to 20 mA
which is auxiliary output, and there are 1 output contact points. As the input contact points, there are 3 contact
points, which can be used as hold input or pulse input depending on the setup.
Feature of the product
1)Convenient to use
●

(Carefully read the following before using the unit)
Feature of the Product and Safety Precautions

4 PORA ELECTRIC MACHINERY CO.,LTD.
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.

·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.
2)Arrangement of the Terminals
Terminal pad
Wrong connections of power terminals (be also careful of the sequence that normal
loads use power), contacts of DC input/output wires and power wires, and short circuits
of output wires etc. may be a cause of serious damages.
Caution : Check Power Input and Wiring

※ If the tension value of the load still shows a minus figure
even after it is connected as above, exchange the green
and blue terminals for the connection.
Pick-up type and load cell type tension detectors have different terminal colors. Due to the potential risks
of malfunction & damages to the unit, make sure to check the terminals and match their respective colors.
Precaution :
Check Different Connecting Terminals Based on the Detector Types

· The mounted value (actual tension) on the display become zero as the
left figure with a beeping sound of the buzzer, and the zero setup is
finished. (※ The mounted value may not be zero depending on the setup
condition.)
·After the zero setup, carry out the span setup.

How to Handle Problems of ZERO/SPAN Setup
(※ How to handle problems of the load cell and pickup setup)
1.Problems appeared when performing the span setup without zero setup
2. When a warning window, which indicates the tension detector’s
wiring is wrong, is appeared in the span setup after zero setup
· When pressing the ‘OUT/SPAN button’ at length for span setup without
performing zero setup, a screen is appeared as the left figure. (If zero
setup is not completed, you cannot perform span setup.)
· In such a case, press the ‘FN button (CANCEL)’ to change into the
control screen, then refer to the ‘ZERO/SPAN setup’ on page 14 to
carry out from zero setup to span setup once again.
· When the wiring of tension detector’s terminal block is wrong, one of the three warning messages above is
appeared depending on its condition.
· In such a case, refer to the ‘Tension Detector Installation method ’ on page 8 to correctly modify the tension
detector’s wiring of the relevant warning message.
· After correctly modifying the tension detector’s wiring, press the ‘FN button (CANCEL)’ to change into the
control screen.
·Refer to the ‘ZERO/SPAN Calibration’ on page 14 to carry out from zero setup to span setup once again.

※Span Calibration
Span adjustment of the tension detector :The load of the tension detector by the tension of the material
varies depending on the angle at which the detector or the material is installed. Span is conducted in
order to complement this.
(※Select a weight equivalent to 30 to 100 % of the maximum capacity of the tension detector and install it on the
roller as follows: For example, if the maximum load of the tension detector is 100 kg, select a weight between 30 and
100 kg.)
If the span setup has not been properly
done, carry out the work again from zero
adjustment.

SensorCheck
(Auto mode is used to automatically control the tension of the material in accordance with the set tension value)
2.Auto Mode
(1) Object tension by changing the value and verify that the value of the tension control.
(2) You can use after change 'P·I·D Gain' value when the tension value is not controlled and changing
value is too big.
(3)Setup Mode→ PARAMETER SET→Tension display is set in Screen Setup. (※Refer to page 26.)
(4) After exiting setup mode, DIAL button is used to check whether the output and tension change or not changing
the manually controlled output value in manual mode.
(5) If the tension value wobbles too much, stabilize the tension value by adjusting the tension display filter value in
Setup Mode →PARAMETER SET→FILTER SET. (※Refer to page 25.)
(6)Check whether the setup is normal or not.
③Tension full-scale value
Setup in Setup Mode
‥Enter (2.PARAMETER SET) → (1.SENSOR SET) in Setup Mode.
‥Set (1. Tension Full-scale) to twice the automatic target tension after setting the span.
①Zero Calibration
<Zero setup should be carried out with the roll for detection assembled and without material and pendulum>
Setup in Setup Mode
‥Enter (2.PARAMETER SET) → (1.SENSOR SET) in Setup Mode.
‥Activate the zero value by pressing DIAL button in (4.ZERO ADJ), and then save it by pressing the DIAL button again.
②Span Calibration

button again.
‥Activate the span value by pressing DIAL button in (5.SPAN SET), and then save it by pressing the DIAL button again.
④Setup check
‥ Look at the ADC. ZERO, SPAN and S-Z values in the (6. I/F check) → (3. TG/ADC), and check whether the setup is
normal or not. (※Refer to page 26.)

Auto Mode P·I·D Gain Setup
The gain which determines the responsiveness of the tension control may be set to the normal standard.
(Gain adjustment can be set only in auto mode)
·Enter P·I·D Gain setup mode by long pressing DIAL button in auto mode.
·Set the desired gain value by turning the DIAL after activating the P value or I value by pressing DIAL button.
(If you set the P gain value too low, the material would not be wound evenly because its response speed has slowed down,
on the contrary, if you set the gain value too high, there would be a vibration phenomenon on the machine.)
·When DIAL button is pressed long, gain setup mode will be closed.
·Refer to page 18 for the detailed P·I·D gain setup.

<※ The acceleration and deceleration speeds of the output voltage are proportionately adjusted. (The setup is done within the
range of 1 to 1000, and it is the maximum when it is set to 1000)>
●Increasing the P gain value will improve the responsiveness. Instead, the stability will get worse.
●While decreasing the P gain value will deteriorate the responsiveness, the stability will be improved.
●If vibration (hunting) is severe as in the case of P1, lower the P gain value gradually.
