CONTIWEB Product Lines We Repair
Our engineers are trained on the full CONTIWEB product range. Below are the major product families we service.
CONTIWEB Web Guide Controllers
Closed-loop web guiding systems with edge detection feedback and proportional actuator control. Common repairs include edge sensor failures, amplifier module burnout, and proportional solenoid stiction causing calibration drift and web misalignment.
CONTIWEB Tension Control Systems
Load cell-based or dancer roll feedback tension regulation for unwinding and rewinding. Typical faults include load cell signal degradation, amplifier output limitations, and proportional valve response lag leading to tension oscillation.
CONTIWEB Edge Detection and Steering Sensors
Inductive proximity and optical edge sensors with integrated signal conditioning. Repair issues involve sensor contamination, PCB corrosion in humid environments, and signal amplifier hysteresis adjustment.
CONTIWEB Proportional Valve Amplifiers
PWM and analog amplifiers for proportional solenoid control in guiding and tension actuators. Common faults include PWM circuit failure, spool stiction, feedback potentiometer wear, and amplifier thermal shutdown.
CONTIWEB HMI and Data Logging Panels
Touchscreen and legacy membrane keypads for web line supervision and parameter tuning. Failures include display backlight degradation, capacitive touch sensor failure, and EEPROM corruption.

6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common CONTIWEB Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CONTIWEB equipment arriving at our workshop.
- ✓Edge sensor signal loss or intermittent dropout — CONTIWEB inductive or optical sensors experience contamination, cable break, or connector corrosion in humid or dusty mill environments. Amplifier feedback loop becomes unstable, causing erratic web steering.
- ✓Proportional solenoid stiction or sluggish response — CONTIWEB proportional valve solenoids accumulate varnish deposits or mineral buildup from hydraulic/pneumatic fluid degradation. Spool movement delays cause overshooting in web position and tension control loops.
- ✓Load cell output signal drift or non-linearity — CONTIWEB tension control systems experience load cell signal conditioning failure, amplifier offset drift, or cable shielding compromise. Calibration becomes inaccurate, leading to tension loss or over-tension cycles.
- ✓HMI touchscreen display unresponsive or degraded — CONTIWEB control panel displays suffer backlight LED aging, capacitive touch sensor noise, or partial LCD pixel failure in high-temperature converting rooms. Operator loses real-time web tension and position feedback.
- ✓Amplifier thermal shutdown or power supply collapse — CONTIWEB proportional amplifiers overheat due to heatsink fouling, excessive PWM duty cycle, or aging electrolytic capacitors failing short. Power rails drop, disabling solenoid control.
- ✓Calibration memory loss or parameter corruption — CONTIWEB HMI EEPROM or FLASH memory corruption from power surges, improper shutdown, or firmware version mismatch. Web guide and tension setpoints revert to factory defaults, halting production.

Frequently Asked Questions — CONTIWEB Repairs
Do you repair CONTIWEB equipment anywhere in India?+
Yes. Synchronics repairs the full CONTIWEB product range — web guides, tension controllers, edge sensors, proportional amplifiers, and HMI panels. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Nagpur, and all other cities. Central facility in Vadodara, Gujarat with 180+ engineers and 30 years of industrial electronics expertise.
What is the typical turnaround time for CONTIWEB web guide or tension control repair?+
CONTIWEB sensor and amplifier repairs typically take 5-7 working days from receipt at our Vadodara facility. Web guide mechanical recalibration and proportional valve cleaning can extend to 10 days. We offer priority express service — 48-72 hours — for emergency shutdowns. Fast turnaround keeps your converting line productive.
Can Synchronics handle CONTIWEB legacy equipment and newer closed-loop systems?+
Absolutely. Synchronics repairs both classic CONTIWEB analog controllers and modern digital networked systems. We stock obsolete edge sensor modules, proportional amplifier PCBs, and load cell interface cards. Our bench technicians reverse-engineer schematic diagrams and troubleshoot vintage systems without original documentation.
How do you diagnose CONTIWEB edge sensor or proportional solenoid faults?+
Our engineers perform input-output signal tracing, load cell linearity testing, and proportional valve frequency response analysis using oscilloscopes and specialized test benches. We bench-test CONTIWEB amplifiers under simulated web line loads and verify closed-loop control stability before return. Detailed diagnostic reports guide preventive maintenance on your production line.
Does Synchronics offer CONTIWEB preventive maintenance or sensor recalibration services?+
Yes. We provide on-site CONTIWEB sensor calibration, proportional valve cleaning, and firmware updates to prevent downtime. Many Indian converting and automotive suppliers contract annual maintenance visits to replace aging load cells, re-solder amplifier connections, and backup calibration memory before failures occur.
How do I send my CONTIWEB unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a CONTIWEB drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on CONTIWEB repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your CONTIWEB unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
