Elder Product Lines We Repair
Our engineers are trained on the full Elder product range. Below are the major product families we service.
Elder PLC Series (ES, EH, EX range)
Modular programmable logic controllers for discrete and continuous control. Common faults include processor card failures, input/output module burnouts, memory corruption, and communication port damage. Indian manufacturers rely on these controllers in textile looms, packaging lines, and automation systems.
Elder VFD Series (EV-M, EV-L, EV-H)
Variable frequency drives for three-phase AC motor control. Repair issues include IGBT module failures, gate drive circuit burnout, capacitor aging in humid environments, and firmware corruption. Widely deployed in pump systems, fans, and conveyors across Indian sugar mills and chemical plants.
Elder Soft Starter Series (SS-Ultra, SS-Prime)
Solid-state soft starters for reduced inrush current and smooth motor acceleration. Common faults: thyristor short circuits, triggering circuit failure, heatsink thermal degradation, and control terminal shorts. Essential for high-speed spindle drives in textile mills and crushers in cement plants.
Elder HMI Touchscreen Series (ET-Panel 7, ET-Panel 10, ET-Display)
Human-machine interface panels for operator control and real-time monitoring. Repair challenges: resistive/capacitive touch sensor degradation, LCD backlight failure, power supply module burnout, and communication gateway errors. Prevalent in sugar processing control rooms and pharmaceutical batch systems.
Elder Communication Modules (ECM-485, ECM-Ethernet, ECM-Profibus)
Industrial communication interfaces for Modbus RTU, Ethernet, Profibus DP, and proprietary protocols. Faults include RS-485 transceiver chip burnout, isolation optocoupler failure, network termination resistor issues, and protocol stack firmware corruption. Critical for multi-zone coordination in Indian manufacturing plants.
Elder Power Supply Modules (PSM-24, PSM-48, PSM-110)
Regulated DC power supplies for control circuit and logic board power. Failure modes: capacitor ripple failure in high-temperature factory environments, rectifier diode shorts, feedback regulation circuit drift, and overvoltage protection relay faults. Indispensable backup in Indian chemical and food processing plants.

Common Elder Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in Elder equipment arriving at our workshop.
- ✓Elder PLC processor card not initializing — Internal flash memory corruption due to power surges during load shedding or incomplete firmware upload. Affected by India's variable grid quality and sudden shutdowns in factory power systems.
- ✓Elder VFD output short or reduced drive torque — IGBT module gate drive failure or thyristor short circuit in the power stage. Common in humid environments (sugar mills, textile wet zones) where condensation bridges gate control traces.
- ✓Elder soft starter thyristor triggering failure — Optocoupler degradation in the control circuit or snubber capacitor leakage. Causes uneven phase triggering, motor jerk, and eventual stalling. Typical in high-duty-cycle mill drives operating 12-18 hours daily.
- ✓Elder HMI touchscreen non-responsive or partial touch zones dead — Resistive membrane layer wear, contamination under glass (common in dusty Indian factory environments), or capacitive sensor IC failure from ESD during maintenance.
- ✓Elder ECM-485 communication module packet loss or CRC errors — RS-485 transceiver chip damage from cable surge injection, isolation optocoupler fatigue, or termination resistor mismatch in long-run cabling (>500m in sprawling mills).
- ✓Elder PSM-24 power supply output voltage drifting or shutdown under load — Electrolytic capacitor dry-out and ESR rise in high-temperature control cabinets (ambient 45-50°C in Indian summers), or feedback regulator IC thermal drift.

Frequently Asked Questions — Elder Repairs
Do you repair Elder equipment anywhere in India?+
Yes, absolutely. Synchronics repairs the complete Elder product spectrum—PLCs, VFDs, soft starters, HMI panels, communication modules, and power supplies. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Indore, and 100+ other cities. All repairs are centralised at our Vadodara, Gujarat facility with 180+ qualified engineers and calibrated test equipment.
What is the typical repair turnaround time for Elder VFD boards?+
Standard turnaround is 5-7 working days for component-level repair (IGBT replacement, gate drive rework, capacitor bank overhaul). Urgent express repairs with onsite consultation can be arranged within 48 hours for critical textile mill and sugar factory drives. All Elder VFDs are load-tested on our motor simulator before return.
Can you repair Elder PLC modules that show 'E01' or 'E03' error codes?+
Yes. E01 indicates memory fault (flash or RAM), E03 indicates communication interface failure. Synchronics diagnostic test rig pinpoints whether the error originates in the CPU, memory module, or communication gateway IC. We perform memory recovery, firmware reflash, and communication port rework using original Elder recovery tools. Your backup configuration is restored from your supplied backup file.
Do you stock Elder spare parts or only repair boards?+
We repair and refurbish entire boards. For critical IGBT modules, capacitor banks, and communication ICs, we source authentic replacement components through authorised Elder distributors. We do not use counterfeit or grey-market parts. If a board cannot be economically repaired, we advise replacement and can source new Elder modules at competitive rates.
How do you ensure repair quality and prevent recurrence of Elder equipment faults?+
Every repaired Elder unit undergoes three-stage validation: component-level test, integrated board test under simulated load, and final functional acceptance test matching your original duty cycle parameters. We issue a detailed fault report, repair method summary, and 12-month warranty on all repairs. We also provide preventive maintenance recommendations to avoid repeat failures.
How do I send my Elder 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 Elder 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 Elder 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 Elder 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.
