FELLER ENGINEERING Product Lines We Repair
Our engineers are trained on the full FELLER ENGINEERING product range. Below are the major product families we service.
FC-Series PLCs
Compact programmable logic controllers designed for textile machinery, packaging lines, and process automation. Common faults include memory corruption, input/output module failures, and communication protocol errors after power surges.
FI-Net Industrial Communication Modules
Fieldbus interface cards for Profibus, MODBUS, and proprietary Feller protocols. Repair focus includes connector corrosion, firmware degradation, and protocol stack failures in humid Indian manufacturing environments.
FM-Motor Control Modules
Dedicated motor control and feedback interface units for AC/DC servo and stepper applications. Typical failures involve power stage transistor degradation, encoder input circuit failures, and analog-to-digital conversion errors.
FS-Safety PLC Modules
Safety-rated control modules meeting EN 61508 SIL 3 standards for critical shutdown and emergency stop circuits. Repairs address redundant channel synchronization issues, safety relay failures, and diagnostic port malfunctions.
FP-Power Supply Units
Ruggedized industrial power supplies for 24VDC and 48VDC control system applications. Common failures include capacitor aging under high-temperature conditions, voltage regulation circuit faults, and backup battery charging failures.
FT-Touchscreen Terminal Interface
Industrial HMI terminals with 7-inch to 15-inch displays for operator control and system monitoring. Repair scope includes display backlight failures, touchscreen calibration drift, and embedded Linux OS corruption.

Common FELLER ENGINEERING Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FELLER ENGINEERING equipment arriving at our workshop.
- ✓FC-PLC memory card read failures — Feller Engineering's FC-series uses proprietary EEPROM modules that degrade under thermal cycling common in Indian textile mills and dye houses. Humidity ingress and electrolytic corrosion at the card interface socket cause intermittent program execution and logic errors.
- ✓FI-Net Profibus protocol communication loss — Feller FI-PROF-01 modules exhibit transceiver IC failures after sustained fieldbus noise on factory floors with high-current motor drives. Industrial EMI from unshielded cable runs and improper grounding in Indian sugar mills and paper plants triggers cumulative silicon degradation.
- ✓FM-Motor module encoder signal loss — Feller FM-SERVO and FM-STEP modules use opto-isolated encoder input stages that fail when connector pins corrode from moisture ingress in pharmaceutical process environments. Secondary IC failures occur when feedback signal ground loops exceed 2V peak-to-peak.
- ✓FS-Safety module redundant channel drift — Feller FS-SAFE-02 and FS-REDUNDANT-03 modules accumulate timing errors after 5+ years of operation due to crystal oscillator aging. The two safety channels desynchronize beyond the 10ms tolerance window specified for SIL 3 compliance, triggering nuisance safety faults.
- ✓FP-Power supply voltage regulation overshoot — Feller FP-24V and FP-48V supplies operate with tight feedback loop bandwidth in designs optimized for Swiss clean-power grid conditions. Indian industrial plants with generator backup, phase angle control SCR loads, and frequent voltage transients cause the PWM controller IC to oscillate, producing 32V spikes on 24V rails.
- ✓FT-HMI touchscreen calibration loss after firmware update — Feller FT-7WS and FT-10TS terminals store touchscreen calibration data in shared flash memory sectors that partially corrupt during firmware upload via unreliable serial or network connections common in Indian plant intranets with legacy infrastructure.

Frequently Asked Questions — FELLER ENGINEERING Repairs
Do you repair Feller Engineering equipment anywhere in India?+
Yes. Synchronics repairs the complete Feller Engineering product range - FC-series PLCs, FI-Net communication modules, FM-motor controllers, FS-Safety systems, FP-power supplies, and FT-HMI terminals. We offer PAN India door-to-door pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all tier-2 industrial cities. All repairs are completed at our Vadodara facility with certified technicians and Swiss-standard test equipment.
What is the typical turnaround time for Feller PLC firmware corruption repair?+
Feller FC-series PLC firmware recovery typically requires 3-5 business days including diagnostics, EEPROM content extraction, firmware verification against your backup, functional testing, and documentation. If you lack a firmware backup, we coordinate with Feller Engineering's Swiss headquarters or authorized distributors to source certified copies. Express turnaround within 48 hours is available for mission-critical textile mill and pharmaceutical installations.
Can Synchronics repair Feller FI-Profibus modules without factory replacement cards?+
Yes. Synchronics specializes in component-level repair of Feller FI-PROF-01 and similar fieldbus interface cards. We replace failed transceiver ICs, repair corroded connector pins, reflow solder joints, and restore galvanic isolation circuits using equivalent-specification components. We do not require factory replacement cards. This approach saves 60-70% compared to purchasing new modules and eliminates 4-6 week lead times from Switzerland.
Do you provide SIL 3 compliance certification after repairing Feller Safety PLC modules?+
Yes. Synchronics repairs Feller FS-Safety-rated modules and issues formal SIL 3 compliance reports meeting EN 61508 standards required by Indian Directorate General of Factory Advice Service & Labor Institute (DGFASLI) and state labor departments. We perform redundant channel synchronization testing, safety function verification, and maintain complete repair traceability documentation for your machinery safety file.
What is the cost advantage of repairing versus replacing a failed Feller motor control module?+
Feller FM-SERVO and FM-STEP module replacements cost INR 45,000-85,000 per unit plus 4-6 week lead time from Switzerland. Synchronics repairs the same modules for INR 12,000-22,000 within 5-7 business days, delivering 70-80% cost savings. For Indian textile mills and machine tool builders operating thin margins, component-level repair represents substantial capital preservation while maintaining equipment availability.
How do I send my FELLER ENGINEERING 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 FELLER ENGINEERING 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 FELLER ENGINEERING 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 FELLER ENGINEERING 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.
