3. Specification Parameters

4. Working Principle

1. Power‑On Initialization and Overall Self‑TestAfter powered by DC24 V regulated supply, the module automatically completes overall initialization, sequentially performing hardware‑circuit self‑test, signal‑port detection, communication‑protocol loading, parameter initialization, sensor‑loop verification and system‑condition calibration. It comprehensively detects hidden risks such as hardware failure, wiring abnormality, parameter disorder and sensor fault. Upon passing self‑test, it enters standby measurement‑control status, establishes signal interconnection with tension sensors, actuators and upper‑level control system and waits for production‑line operation commands.

   
   

2. Tension‑Signal Acquisition and Accurate Pre‑ProcessingDuring line operation, the module collects weak millivolt‑level raw feedback signals from tension sensors in real‑time. Multi‑stage digital filtering, electromagnetic‑noise rejection, temperature‑drift compensation and linear‑calibration algorithms perform noise reduction, waveform shaping, error correction and range conversion for raw signals. Unstable raw analog signals are converted into accurate, stable and linearly‑matched standard tension values. Signal drift induced by industrial interference and equipment temperature difference is thoroughly eliminated to provide reliable data foundation for closed‑loop regulation.

   
   

3. Constant‑Tension Closed‑Loop Computation and Dynamic RegulationWith built‑in proprietary tension‑control algorithms, the module compares real‑time measured tension against system‑set tension threshold and dynamically computes regulation deviation. For conditions including line start‑stop, acceleration/deceleration, load fluctuation and web‑tension variation, accurate regulating signals are automatically output to control inverters, tension cylinders, web‑guide actuators and other executing devices. Operating parameters are revised in real‑time to dynamically balance web tension and maintain constant tension. Process defects caused by abrupt tension change are prevented to realize fully‑automatic stable regulation without manual intervention.

   
   

4. Data Transmission and Real‑Time Working‑Condition SynchronizationVia Profibus‑DP fieldbus, the module uploads real‑time tension values, equipment operating status, process parameters and working‑condition information to upper‑level PLC/DCS control system. Meanwhile it receives tension set‑points, start‑stop commands and parameter‑modification commands from upper level, parses and executes these commands. Bidirectional data exchange, condition synchronization and remote control between field devices and upper‑level system are realized to satisfy centralized‑management requirements of automatic production lines.

   
   

5. Fault Self‑Diagnosis, Safety Protection and TraceabilityDuring full‑period operation, sensor loops, signal status, power‑supply condition, communication links and hardware status are continuously monitored. Faults such as sensor wire breakage, signal over‑range, circuit short‑circuit, communication interruption and power‑supply abnormality can be accurately identified. Once a fault is triggered, safety‑protection mechanism is activated immediately: abnormal outputs are latched, local alarm signals are generated and fault codes are uploaded. Fault timestamps, operating parameters and abnormal logs are automatically recorded to avoid fault escalation and deliver complete data support for maintenance troubleshooting and rectification.

5. Common Faults and Troubleshooting

1. Phenomenon: No display after power‑on, equipment fails to start, module unrecognized by systemPossible Causes

   ① Loss of DC24 V power supply, excessive voltage deviation, reversed polarity or large power‑supply ripple;

   ② Loose module terminals, poor wiring contact or open circuit;

   ③ Damaged internal power‑supply circuit or lost/crashed firmware;

   ④ Circuit‑board short‑circuit caused by humid and dusty installation environment.

Troubleshooting

Power off the system for full discharge. Measure DC24 V voltage, polarity and circuit continuity; inspect circuit breakers and terminal tightness. Clean dust and moisture on module surface and terminals, then retighten wiring. Re‑flash original‑factory firmware and restore factory‑standard parameters. If no response persists with normal power and wiring, hardware failure is confirmed; replace with original spare part.

2. Phenomenon: Jittering tension readings, zero‑point drift, unstable measurement dataPossible Causes

   ① Loose tension‑sensor wiring, damaged cable shielding or severe signal interference;

   ② Zero‑point uncalibrated, incorrect range parameters or long‑term parameter drift;

   ③ Signal distortion caused by on‑site variable‑frequency‑drive interference and electromagnetic radiation;

   ④ Degraded signal‑acquisition circuit and reduced precision.

Troubleshooting

Fully inspect sensor wiring and shielding layers, fasten connectors, repair damaged shielding and improve grounding anti‑interference measures. Re‑execute zero‑point calibration and range calibration via module HMI and correct disordered parameters. Optimize field routing and keep cables away from power‑cable interference zones. If faults remain after calibration and interference rectification, module precision degradation is confirmed; replace the module.

3. Phenomenon: Failed constant‑tension regulation, erratic web tension, web wrinkling / stretching deformationPossible Causes

   ① Improper tension setting and mismatched closed‑loop PID parameters;

   ② Aged sensor with reduced sampling precision and distorted feedback signal;

   ③ Sticking actuators with slow response and mismatched regulation;

   ④ Disordered module control logic and program exception.

Troubleshooting

Re‑optimize tension set‑point and closed‑loop PID parameters to adapt to line conditions. Inspect and calibrate tension‑sensor precision and replace aged sensors. Rectify sticking and slow‑response issues of actuators to guarantee regulation synchronization. Reboot module to reset program and restore factory control logic. If faults persist, control‑circuit failure is confirmed; replace with original module.

4. Phenomenon: Upper‑level‑system communication interruption, tension‑data unreadable, remote control disabledPossible Causes

   ① Damaged Profibus cable, loose connectors or abnormal bus terminating resistor;

   ② Misconfigured module communication address, baud rate and protocol parameters;

   ③ Bus networking conflict and duplicate device addresses;

   ④ Aged communication chip and faulty communication circuit.

Troubleshooting

Inspect communication bus, connectors and terminating resistors; replace damaged cables and fasten connectors. Verify and unify communication address, baud rate and bus parameters; eliminate address conflicts. Reboot bus and module communication program for re‑networking. If communication still fails with correct wiring and parameters, communication‑circuit failure is confirmed; replace spare part.

5. Phenomenon: Frequent module alarms, large‑amplitude tension fluctuation during start‑stop, unstable operationPossible Causes

   ① Improper setting of start‑stop buffer and tension‑ramp parameters;

   ② Abrupt line‑speed change and load fluctuation exceeding module adaptive‑regulation range;

   ③ Heavy‑duty long‑time operation, internal dust accumulation and poor heat dissipation;

   ④ Stuck firmware and uncalibrated long‑term parameter drift.

Troubleshooting

Optimize start‑stop buffer and tension‑ramp parameters to improve working‑condition adaptability. Standardize line start‑stop operation and avoid sharp acceleration/deceleration and abrupt‑load change. Clean module dust and improve cabinet ventilation. Calibrate tension parameters periodically and flash stable original‑factory firmware. In case of recurring faults, module performance aging is confirmed; replace spare part in advance to prevent production failure.

6. Phenomenon: No feedback from sensor, module fails to acquire tension dataPossible Causes

   ① Damaged sensor, open circuit or reversed wiring polarity;

   ② Damaged acquisition channel or disabled port parameters;

   ③ Module signal‑protection latch triggered by circuit short‑circuit;

   ④ Abnormal signal‑acquisition program.

Troubleshooting

Verify sensor integrity and circuit continuity, correct wiring polarity and replace faulty sensor. Check channel parameters, enable signal‑acquisition function and release fault‑protection latch. Reboot module for program reset and initialization. If no signal is obtained with normal sensor and wiring, acquisition‑circuit failure is confirmed; replace module timely.
