KTC838AC Automatic tension controller Tapper tension controller
KTC838AC adopts the sketch liquid crystal display which shows the Chinese and English more clearly
and send out 0~24V/4A to drive the magnetic clutch/brake, or output 0~5V, 0~10V voltages signal to control
the frequency converter, servo motor or other actuators so as to perform the highly accurate control. It is
widely used in the industries of paper-making, printing, packing and textiles printing, etc.
KTC838AC can be set as full-automatic tension controller or radius tension controller. It is full-automatic
tension controller when system's mode [28]is set as automatic tension control and can be formed as a
closed-loop tension control system with installing tension transducer. It is radius tension controller when
system's mode [28]is set as radius tension control, it just needs to install the proximity switch/encoder to
measure the coiled materials' radius and perform the tension control according to the radius.
Chapter 4 mainly introduces the debugging and operation of full-automatic tension controller while
Chapter 5 mainly introduces the debugging and operation of radius tension controller.
FEATURES:
1.Adopt the 128X96 sketch liquid crystal displayer with choice of Chinese/English display and user friendly
operational interface.
2.Function of full-automatic tension controller or radius tension controller choosing.
3.Full-digital design, no adjustable , simple process of tension calibration, the tension
measurement is highly accurate, stable and reliable.
·Can receive the input signal of one-way/two-way transducer, adjust various tension transducer as input
signal
A.can choose the micro-displacement specialized tension transducer ( input signal range +-300m V,
5V power supply).
B.can choose strain gauge tension controller ( input signal range +-20m V, 10V power supply).
4.Adopt the proximity switch to measure the radius can realize the function of taper tension control.
5.Can choose the function of serial communication , also can choose the communication port of RS485 or RS232 to connect with PLC, PC to make up the distribution system.
6.Adopt no-overshot PID algorithm, guarantee no-over shot of tension during the process of system's
distributed control system.
7.Have the function of two-axel switching and acceleration/deceleration control.
8.Switch of automatic/manual control without interference.
9.Protect the password parameters, avoids mis-operation.
10 Adopt the switch power supply with strong adaptability (185~264V), guarantee long-term stable
operation.
