GMR Product Lines We Repair
Our engineers are trained on the full GMR product range. Below are the major product families we service.
GMR DCS (Distributed Control Systems)
GMR's advanced distributed control platforms for large thermal and renewable power plants. Common issues include field module communication failures, sensor input drift, redundancy switching failures, and firmware compatibility problems after plant upgrades.
GMR PLC (Programmable Logic Controllers)
Compact and modular PLCs used in GMR airport ground support, highway toll management, and industrial automation. Frequent faults include I/O card failures, Ethernet port burnout, programming memory corruption, and real-time clock drift.
GMR HMI/SCADA (Human Machine Interface)
Touchscreen and operator interface systems for power plant monitoring and control. Common defects: LCD panel dead pixels or backlight failure, capacitive touch panel unresponsiveness, Modbus/TCP communication timeouts, and firmware version mismatches.
GMR Power Quality Analyzer (PQA)
Three-phase power monitoring and harmonic analysis modules deployed in substations and industrial plants. Frequent failures: voltage sensor drift, current transformer saturation, SD card data corruption, and precision clock desynchronization.
GMR Renewable Energy Controllers
Specialized control modules for solar PV inverter integration and wind farm management. Issues include IGBT driver circuit failures, phase-lock-loop instability, grid synchronization loss, and DC-link capacitor degradation.
GMR Safety Instrumented Systems (SIS)
High-integrity safety-critical controllers for power plant shutdown and emergency response. Defects: dual-channel voting logic intermittent faults, solenoid driver circuit failures, diagnostic memory checksum errors, and sensor input validation failures.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common GMR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GMR equipment arriving at our workshop.
- ✓GMR DCS Field Module Communication Loss — Shielded twisted-pair cabling corrosion at terminal blocks due to coastal humidity (common in Mundra, Dabhol plants), or Profibus/Ethernet gateway module firmware mismatch after system patch updates.
- ✓GMR PLC I/O Card Slot Burnout — Transient overvoltage from unshielded sensor wiring during monsoon season, or incorrect module insertion damaging hot-swap connectors. Common in airport baggage handling and toll collection systems operating 24/7.
- ✓GMR HMI Touchscreen Unresponsiveness — Capacitive touch controller IC failure due to electrostatic discharge during maintenance, or firmware corruption from unexpected power loss. Affects operator control during critical power plant operations.
- ✓GMR Power Quality Analyzer Voltage Drift — Precision analog front-end (AFE) operational amplifier aging after 8+ years, or zener reference diode degradation in the measurement channel. Leads to harmonic measurement errors and false alarm thresholds.
- ✓GMR Renewable Energy Controller IGBT Gate Driver Failure — Photocoupler LED aging in the isolated gate drive circuit, exacerbated by high ambient temperatures in solar inverter cabinets (common in Rajasthan, Gujarat plants). Leads to missing IGBT switching pulses and converter shutdown.
- ✓GMR Safety SIS Dual-Channel Voting Logic Intermittent Fault — Boundary scan (JTAG) chain open or solder joint fatigue in the redundant comparison logic FPGA, often triggered by vibration during plant startups. Can mask critical shutdown signals during emergency scenarios.

Frequently Asked Questions — GMR Repairs
Do you repair GMR equipment anywhere in India?+
Yes. Synchronics is the authorized service partner for GMR industrial control systems across India. We offer same-day pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Surat, Vadodara, and all tier-2 cities. All repairs are completed in our Vadodara facility (Gujarat) with 7-14 day turnaround for standard modules. Express 48-hour service available for critical power plant equipment.
Can you repair GMR DCS modules without shutting down the power plant?+
Yes. For GMR Distributed Control Systems, we offer hot-standby module replacement and N+1 redundancy planning. If your plant runs dual redundant DCS chains, we can swap failed modules while maintaining control continuity. Synchronics coordinates with your control room team to schedule maintenance windows and provides on-site commissioning support.
What happens if my GMR PLC firmware is corrupted?+
Synchronics extracts and restores firmware from secure EEPROM backup or re-programs the PLC using GMR's certified bootloader. We maintain historical firmware versions for models dating back to 2002. If original firmware cannot be recovered, we reverse-engineer the ladder logic from your backup files or work with your automation team to reconstruct the program. All restored PLCs undergo full I/O loop testing before return.
Do you handle GMR Safety Instrumented Systems (SIS) repairs?+
Yes. Synchronics is certified to repair IEC 61508-compliant GMR SIS modules. We perform full functional safety assessment, replace failed components, and re-certify the system to your plant's Safety Integrity Level (SIL). All repairs include functional safety documentation and calibration certificates required for regulatory compliance.
How much does GMR equipment repair cost?+
GMR repair costs depend on the failed component and module complexity. DCS/PLC card repairs typically range from Rs. 8,000 to Rs. 35,000. Full module replacements cost Rs. 50,000 to Rs. 2,50,000. Synchronics provides free diagnostic assessment and written quotation within 24 hours of receipt. We also offer annual preventive maintenance contracts with 15% discount on parts and labour for high-availability facilities.
How do I send my GMR 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 GMR 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 GMR 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 GMR 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.
