Expert repairs for BST web guiding, measurement sensors, and process control systems.
BST Product Lines We Repair
Our engineers are trained on the full BST product range. Below are the major product families we service.
eltromat Web Guide Systems
Closed-loop web steering solutions for printing and converting lines. Common faults include camera module failures, servo motor malfunctions, and control signal loss due to connector corrosion or PCB damage in high-temperature environments.
Coating Thickness Measurement Systems
Non-contact measurement for wet and dry film thickness in flexo, gravure, and offset printing. Repair issues often involve X-ray tube faults, detector sensor degradation, and measurement drift requiring recalibration or module replacement.
Color Management and Control Units
Spectral analysis and color correction controllers for print quality assurance. Frequent faults include spectrophotometer calibration loss, RS485 communication errors, and power supply instability in dusty printing mill environments.
Tension Control Systems
Load cell-based tension measurement and feedback control for web processing. Common failures include load cell amplifier drift, 4-20mA signal conditioning circuit faults, and analog I/O board damage.
Optical and Sensor Modules
Precision laser and optical sensors for edge detection, registration, and surface inspection in converting lines. Typical repairs involve lens cleaning, optical alignment, photodiode replacement, and ambient light filter restoration.
eltrostat Surface Inspection Systems
Web surface defect detection using line-scan cameras and dedicated image processing hardware. Repair challenges include camera sensor damage, lens contamination, frame grabber failures, and software license key recovery.

Common BST Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BST equipment arriving at our workshop.
- ✓Web guide camera image dropout or blurred vision — BST eltromat WSB camera modules experience optical contamination from lint, powder, or adhesive mist in printing and converting plants. Sensor window degradation or internal lens fogging reduces image contrast, causing guide oscillation or complete control loss.
- ✓Coating thickness measurement reading drift or offset error — BST RTG and DFS measurement systems drift due to X-ray tube aging, detector gain loss, or calibration reference loss after power surges or humidity exposure. Common in coastal Indian plants and humid printing facilities.
- ✓Color management controller spectrophotometer communication failure — RS485 serial link corruption between BST ColorControl unit and spectrophotometer occurs due to EMI in noisy mill environments, damaged cable shielding, or CAN/RS485 termination resistor failure on the PCB.
- ✓Tension control load cell signal erratic or non-responsive — BST RFLEX and TLS load cell amplifier circuits fail due to capacitor aging, bridge excitation voltage loss, or 4-20mA transmitter IC degradation. Moisture ingress in junction boxes is common in humid Indian textile and film plants.
- ✓Surface inspection camera frame grabber freeze or USB timeout — BST eltrostat line-scan camera systems experience frame grabber timeouts due to loose USB/GigE connections, outdated firmware, or PC-side driver conflicts. Power supply voltage fluctuations in Indian plants often trigger intermittent failures.
- ✓Web edge detection sensor laser power loss or misalignment — BST LAM and EFS optical sensors lose laser alignment due to vibration, thermal expansion, or mechanical impact on the sensor head. Lens contamination from coolant spray, dust, or adhesive mist reduces signal-to-noise ratio below detection threshold.

Frequently Asked Questions — BST Repairs
Do you repair BST equipment anywhere in India?+
Yes. Synchronics repairs the full BST product range—web guides, measurement sensors, color controllers, tension systems, and line-scan inspection modules. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, and all major industrial cities. All work is done at our main facility in Vadodara, Gujarat.
Can you recalibrate BST measurement sensors to factory accuracy?+
Yes. Synchronics maintains certified calibration standards for BST coating thickness (RTG/DFS), color management (ColorControl), and tension measurement systems. We use NIST-traceable reference materials and perform full linearity verification across the measurement range. Calibration certificates are provided with a 12-month accuracy guarantee.
What is typical turnaround time for BST web guide repair?+
Most BST eltromat web guide repairs take 5-7 business days depending on fault severity. Camera module replacement is typically 3-4 days. Servo motor rewinding takes 7-10 days. We offer express service for critical production lines—call our hotline for same-day diagnostics and expedited repair scheduling.
Do you repair BST sensor modules without returning entire control cabinet?+
Yes. Most BST optical heads, load cells, and sensor modules can be detached and shipped separately, reducing transport costs and downtime. We repair cameras, photodiodes, laser modules, and spectrophotometer heads in-house. Control cabinets are repaired on-site when feasible.
Can you help prevent BST system failures in humid coastal printing plants?+
Absolutely. Synchronics offers preventive maintenance programs for BST equipment in coastal and high-humidity regions (Mumbai, Chennai, Kochi). We provide humidity-sealed connector upgrades, conformal coating for PCBs, stainless steel hardware replacement, and quarterly recalibration to extend equipment life and reduce breakdown risk.
How do I send my BST 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 BST 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 BST 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 BST 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.
