BENSHAW Product Lines We Repair
Our engineers are trained on the full BENSHAW product range. Below are the major product families we service.
Commander Series Soft Starters
SCR-based soft starters for AC induction motors. Common issues include SCR bridge faults, control board failures, overheating, and communication errors. Repairs require precise power electronics expertise and load testing.
Benshaw VFD Solutions
Variable frequency drives combining soft-start and VFD capability in single units. Typical faults include IGBT failures, DC bus capacitor degradation, encoder interface problems, and parameter loss.
Control Logic and PLC Modules
Custom control boards and logic modules embedded in Benshaw starters. Common failures include relay burnout, analog input card degradation, communication port failures, and firmware corruption.
Bypass Contactor Systems
High-reliability bypass contactors used in soft starter installations to transition from soft-start to across-the-line operation. Faults include coil failures, contact welding, timing misalignment, and mechanical wear.
Thermal and Protection Modules
Integrated thermal overload relays, phase-loss detection, and short-circuit protection circuits. Common issues include sensor calibration drift, relay coil failures, and nuisance trip circuits.

Common BENSHAW Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BENSHAW equipment arriving at our workshop.
- ✓SCR Bridge Short or Open Circuit — Power surges, phase imbalance, or aged silicon-controlled rectifiers cause gate drive failures or junction breakdown in the SCR stack. Common in Commander series starters operating in high-temperature Indian textile mills and steel plants.
- ✓DC Bus Capacitor Failure and Bulging — Extended operation in Indian summer temperatures (40°C+), combined with under-sized cooling or continuous high-load cycling, degrades electrolytic capacitors in the power stage. Electrolyte vaporization causes voltage ripple and device stress.
- ✓Control Board Communication Timeout and Messaging Errors — Benshaw soft starters communicate via RS-485 or proprietary serial protocols. Loose connectors, corrosion in humid Indian factory floors, or firmware version mismatches cause loss of command signals and fault propagation.
- ✓Thermal Overload Relay Nuisance Trips — Benshaw thermal modules drift with age or experience phase-unbalance detection in plants with irregular power quality. Sensor calibration error or stuck relay contacts cause false protection shutdowns costing production hours.
- ✓Bypass Contactor Coil Burnout and No Transition — Benshaw bypass contactors must energize reliably after soft-start ramp completion. Coil burnout results from prolonged energization or loose pole piece, preventing transition and leaving motor in soft-start mode causing overheating and reduced speed.
- ✓Firmware Corruption and Parameter Loss — Power supply interruptions during parameter writes, bad flash memory cells, or incompatible firmware updates can corrupt Benshaw soft starter programming. Equipment loses ramp profile, current limit settings, and protection parameters.

Frequently Asked Questions — BENSHAW Repairs
Do you repair Benshaw soft starters across India?+
Yes, absolutely. Synchronics Electronics repairs the complete Benshaw product line — soft starters, VFDs, control boards, and bypass contactors. We offer free PAN India door pickup from all major cities (Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata) with fast courier return. Our Vadodara facility has Benshaw test benches and original firmware libraries.
What is the typical Benshaw soft starter repair turnaround time?+
Most Benshaw repairs are completed within 5-7 working days, including root cause analysis, component replacement, and full load testing. Critical soft starters are expedited within 48 hours. We provide daily progress updates via phone/email and offer loaner units for extended repairs.
Can Synchronics repair Benshaw starters with obsolete or out-of-production components?+
Yes. For legacy Benshaw Commander models or discontinued versions, we maintain a large inventory of equivalent industrial-grade SCRs, contactors, and control cards. If original parts are unavailable, our engineers source certified alternatives and retune soft-start parameters to match original performance.
Do you handle Benshaw warranty repairs or only third-party maintenance?+
Synchronics repairs all Benshaw equipment regardless of warranty status — whether directly under manufacturer warranty, extended service contracts, or out-of-warranty. We work with Benshaw authorized service partners and provide detailed technical reports for warranty claim processing.
What causes Benshaw soft starters to fail prematurely in Indian climates?+
India's high ambient temperatures (35-45°C in summer), high humidity near coastal areas, and dust-laden environments accelerate component degradation. Poor power quality, frequent load spikes in mines and steel mills, and inadequate cooling ventilation stress SCR junctions and capacitors. Synchronics designs repairs using thermally-upgraded components rated for Indian industrial conditions.
How do I send my BENSHAW 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 BENSHAW 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 BENSHAW 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 BENSHAW 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.
