EVC Product Lines We Repair
Our engineers are trained on the full EVC product range. Below are the major product families we service.
EVC Control Modules (Legacy)
Standalone microprocessor-based controllers for process automation, pump control, and machinery supervision. Common failures include EEPROM data corruption, relay contact welding, and power supply degradation affecting field command response.
EVC Power Drive Systems
Three-phase AC motor drives and soft-starters with integrated fault diagnostics. Typical repair issues include IGBT module breakdown, gate drive circuit failure, and capacitor bank venting in high-temperature mill environments.
EVC Fieldbus & Communication Modules
Profibus DP, CANopen, and Modbus RTU/TCP gateway modules enabling legacy EVC systems to integrate with modern Industry 4.0 networks. Faults typically involve connector corrosion, firmware version mismatch, and signal isolation failures.
EVC PLC & HMI Platforms
Compact programmable logic controllers and touchscreen HMI panels for mill-floor control. Common failures include SD card corruption, SD slot mechanical wear, and display panel backlight LED degradation.
EVC Safety & Monitoring Relays
Safety-rated monitoring relays for motor protection, phase sequence checking, and overvoltage/undervoltage suppression in mission-critical Indian textile and sugar mills. Failures include coil open-circuit, contact arc damage, and nuisance trips from supply harmonics.
EVC Thyristor & Rectifier Modules
Industrial-grade phase-controlled rectifiers and power conversion modules for DC motor drives and electroplating lines. Repair typically involves thyristor stack replacement, gate resistor chain recalibration, and snubber network refurbishment.

Common EVC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EVC equipment arriving at our workshop.
- ✓EVC control module no-power lockout — Primary symptom: unit does not energise despite correct 24V/48V supply. Root cause is typically burnt input fuse, corroded power supply PCB traces due to mill-floor humidity, or internal 12V regulator short-circuit from aging electrolytic capacitors.
- ✓EEPROM corruption causing lost program memory — EVC legacy controllers store program logic in EEPROM. Power failures during write cycles, excessive supply ripple in textile mills, or static discharge during maintenance can corrupt memory blocks, rendering the machine non-functional or in safe-state lockout.
- ✓Motor drive IGBT thermal runaway or cascade failure — EVC power drives in sugar factories face continuous high-temperature ambient conditions (40-50C mill floors). IGBTs fail when gate drive voltage droops below threshold, gate resistor networks degrade, or solder joints crack under thermal cycling, causing uncontrolled short-circuit and component cascade burnout.
- ✓Fieldbus module loses peer communication intermittently — EVC Profibus and CANopen modules suffer contact corrosion in humid mill environments, causing intermittent bus faults and scan cycle timeouts. Root causes: oxidised DB9/Molex connectors, terminator resistor failure, and isolation barrier capacitor drift.
- ✓Soft-starter ramp-up incomplete or jerky motor acceleration — EVC soft-starters in pump control applications fail when phase-control gate resistor networks burn open, snubber RC networks crack, or the gate trigger circuit develops hysteresis due to aged op-amp capacitors. Results in erratic acceleration ramps and mechanical stress on pump seals.
- ✓HMI touchscreen unresponsive or display partial loss — EVC HMI panels experience panel backlight LED degradation (reduced luminance) and SD card slot mechanical wear from repetitive touch-input cycles in high-vibration textile looms and autoclave environments. Firmware corruption in SD card reduces response latency.

Frequently Asked Questions — EVC Repairs
Do you repair EVC equipment anywhere in India?+
Yes. Synchronics repairs the full EVC product range — control modules, power drives, fieldbus gateways, PLCs, and safety relays. We offer PAN India door-to-door courier pickup from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other industrial cities. Your equipment arrives at our Vadodara, Gujarat facility within 3-5 days. We return repaired units via insured courier.
Can Synchronics repair my legacy EVC-300 or EVC-400 controllers?+
Absolutely. Many Indian textile mills and sugar factories still rely on EVC legacy controllers from the 1990s-2000s. Synchronics specialises in restoring these platforms — we stock genuine EVC replacement modules, can recover corrupted EEPROM programs via reverse-engineering, and have the original factory test specifications. Repair turnaround is typically 5-7 working days.
What is your warranty on EVC repairs?+
Synchronics provides a 12-month parts and labour warranty on all EVC repairs, covering defects arising from our workmanship. Warranty includes technical telephone support and one free troubleshooting call if the repaired unit exhibits symptoms during commissioning. For critical production equipment, we also offer 24-month extended warranties at nominal cost.
My EVC motor drive is showing fault code E-15 or E-23. What does this mean?+
EVC drive fault codes vary by series, but E-15 typically indicates gate drive voltage loss or IGBT short-circuit detection, while E-23 signals thermal overload or sensor malfunction. Synchronics diagnoses these codes using EVC factory documentation and our in-house IGBT test bench. We will email you a detailed fault report and repair quotation within 24 hours of receiving your drive.
Can Synchronics upgrade my old EVC system to modern Profibus or Ethernet communication?+
Yes. Synchronics integrates EVC fieldbus gateway modules (Profibus DP, CANopen, Modbus) into legacy systems, enabling integration with modern MES and Industry 4.0 monitoring platforms. We also offer firmware updates where available and can configure new HMI touchscreen interfaces to communicate with your restored EVC controllers. This is a cost-effective alternative to complete system replacement.
How do I send my EVC 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 EVC 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 EVC 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 EVC 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.
