BONAR Product Lines We Repair
Our engineers are trained on the full BONAR product range. Below are the major product families we service.
Bonar Modular Belt Systems
Interlocking plastic modular conveyor belts used in food, pharmaceutical, and packaging industries. Common issues include hinge pin wear, module cracking, electrical actuator failures in automated tracking systems, and electrical connector corrosion in humid environments.
Bonar Mining & Quarry Belts
Heavy-duty rubber conveyor belts for ore, aggregate, and mineral transport in Indian mining operations. Repair focus includes splice degradation, carcass layer separation, embedded pulley failures, and electronic load cell malfunction in weigh belt systems.
Bonar Tensioning & Drive Systems
Electronic belt tension controllers, motor drive interfaces, and automated take-up systems managing conveyor speed and slack detection. Common faults involve PLC firmware corruption, analog tension sensor drift, relay card burnout, and motor encoder signal loss.
Bonar Sugar & Food Processing Belts
Food-grade modular and rubber belts with integrated electronic tracking and hygiene monitoring. Issues include moisture-induced electrical failures, bacterial biofilm causing sensor errors, actuator seal degradation, and control board short circuits.
Bonar Textile Mill Belts
Specialized conveyor solutions for Indian cotton mills, textile processing, and fabric handling. Common repairs involve dust contamination in control electronics, humidity-related capacitor failure, encoder misalignment, and speed control module malfunction.
Bonar Cement & Bulk Material Belts
Reinforced belts designed for high-abrasion cement plants and bulk material handling across Indian infrastructure projects. Frequent issues include electronic slip detection sensor failure, vibration-induced connector loosening, PLC input card burnout, and emergency brake solenoid coil failure.

Common BONAR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BONAR equipment arriving at our workshop.
- ✓Bonar Modular Belt Hinge Pin Electrical Connector Corrosion — Moisture ingress into modular belt tracking sensor connectors due to washdown in food and beverage plants. Indian humidity and wet processing environments accelerate oxidation of copper contact pins, causing intermittent sensor signals and tracking errors.
- ✓Bonar Tensioning System PLC Firmware Corruption & Watchdog Timeout — Power surges from Indian grid fluctuations, inadequate UPS backup, or electromagnetic interference from nearby motor drives corrupt the PLC memory in Bonar ETC-2000 and AutoTension controllers, triggering watchdog faults and belt emergency stops.
- ✓Bonar Load Cell Sensor Drift and Analog Signal Noise — Temperature fluctuations in mining and quarry operations, vibration from heavy crusher equipment, or stainless steel corrosion in salt and chemical processing facilities cause load cell output to drift or produce noisy 4-20mA signals, leading to tension control errors.
- ✓Bonar Motor Encoder Signal Loss and Belt Speed Feedback Failure — Bearing wear in drive motor encoders, damaged encoder cable shielding allowing EMI interference from adjacent electrical cabinets, or accumulated dust in optical encoder windows (common in cement and sugar mills) cause speed feedback dropout.
- ✓Bonar Relay and Solenoid Coil Burnout in Emergency Stop & Brake Systems — Inrush current spikes when emergency brake solenoids activate without proper snubber diodes, or aging relay contacts in Bonar control panels fail after 5-7 years of switching heavy loads in 24/7 Indian mill operations.
- ✓Bonar Conveyor Belt Splice Failure and Electronic Splice Joint Monitoring Malfunction — Poor splice installation, inadequate hot-vulcanization curing time in Indian field repair conditions, or mechanical stress from impact loads cause splice layer separation. Associated electronic splice detection sensors then lose adhesion or corrode, sending false failure alarms.

Frequently Asked Questions — BONAR Repairs
Do you repair Bonar conveyor belt systems and control electronics anywhere in India?+
Yes. Synchronics Electronics repairs the complete range of Bonar modular belts, rubber conveyor systems, tensioning controllers, and electronic monitoring systems across India. We offer pan-India door-to-door pickup and delivery from all major cities including Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and Kolkata. All repairs are performed at our certified Vadodara, Gujarat facility with genuine Bonar components and full system re-commissioning support.
What is included in Synchronics Bonar conveyor system repair service?+
Our repair includes full diagnostic testing of Bonar belt control electronics, PLC programming, analog sensor calibration (load cells, encoders, tension sensors), relay and solenoid replacement, connector cleaning and waterproofing, spare parts replacement with OEM equivalents, full system integration testing, and on-site commissioning support. We provide a 12-month warranty on all repairs and maintain emergency call-out support for critical mill shutdowns.
How do I diagnose a Bonar belt tracking or tensioning failure?+
Check if the Bonar controller displays a specific error code (consult the manual for fault codes). Verify 230V AC power supply stability to the tensioning drive and look for blown fuses or tripped breakers. Inspect load cell connectors and encoder cable for corrosion or loose pins. Use a digital voltmeter to check sensor output voltages — load cells should provide 4-20mA DC and encoders typically output 5V square waves. If faults persist, contact Synchronics for rapid diagnostics; we carry common Bonar spare parts in stock.
Can Synchronics help if my Bonar PLC firmware is corrupted or locked?+
Absolutely. Synchronics has expertise in Bonar ETC-2000, AutoTension, and other proprietary controllers. We recover and restore PLC firmware from backup configurations, reprogram from factory templates, and re-establish all sensor calibration values. If the PLC hardware is damaged beyond software repair, we source and install genuine replacement modules. Turnaround is typically 3-5 working days depending on backup availability.
What is your typical turnaround time for Bonar conveyor system repairs?+
Standard turnaround is 5-7 working days for most Bonar electronics repairs — including diagnostic testing, component replacement, calibration, and full system verification. Urgent repairs for critical production lines can be expedited to 24-48 hours depending on spare parts availability. We maintain stock of common Bonar PLC modules, relay cards, load cell sensors, and connector kits at our Vadodara facility to minimize wait times for Indian manufacturers.
How do I send my BONAR 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 BONAR 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 BONAR 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 BONAR 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.
