ETUNG Equipment We Repair — By Category
ETUNG Product Lines We Repair
Our engineers are trained on the full ETUNG product range. Below are the major product families we service.
ETUNG PLC Controllers
Compact and modular programmable logic controllers with high-speed I/O processing, commonly deployed in textile spinning frames, packaging machinery, and food processing conveyors. Typical repairs address input/output module failures, CPU communication faults, and memory degradation causing ladder logic execution errors.
ETUNG Motion Control Boards
Servo motion controllers and stepper drive cards for precision positioning in semiconductor packaging, PCB assembly, and automated inspection systems. Common failures include capacitor dry-out on power stages, encoder interface signal loss, and PID tuning parameter corruption.
ETUNG HMI Terminal Interface Modules
Human-machine interface touch panels and text displays for machine operator interaction and process monitoring on production lines. Typical faults involve LCD backlight degradation, membrane button contact failure, and serial communication protocol errors with host PLC.
ETUNG Communication Interface Cards
Ethernet, Modbus RTU, and proprietary industrial protocol converter cards enabling multi-device networking in distributed manufacturing systems. Repair focus includes galvanic isolation transformer burnout, RS-485 transceiver chip failure, and firmware corruption on communication firmware EEPROM.
ETUNG Power Supply Modules
Regulated DC power distribution boards and 24VDC switching supplies for PLC and sensor circuits in industrial environments. Common failures stem from thermal stress in high-ambient factories, electrolytic capacitor failure, and voltage regulator IC degradation causing brownout resets.
ETUNG Encoder and Sensor Interface Modules
Incremental and absolute encoder signal conditioning boards with galvanic isolation for feedback-based motion control in spinning frames and packaging machinery. Typical issues include optocoupler failure under sustained vibration, preamp offset drift, and lost calibration data in EEPROM.

Common ETUNG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ETUNG equipment arriving at our workshop.
- ✓ETUNG PLC CPU no boot or watchdog timeout reset — CMOS battery depletion in backup power circuit causes real-time clock loss and parameter memory corruption. Secondary cause is boot EEPROM address bus short or faulty 5V regulation on CPU module.
- ✓ETUNG motion controller axis servo not responding or position drift error — Encoder cable intermittent contact or shielding degradation introduces noise on differential encoder signals. Alternatively, servo amplifier output stage capacitor failure (dry electrolytic) reduces servo loop bandwidth and destabilizes closed-loop control.
- ✓ETUNG HMI touch panel unresponsive or erratic touch input registration — LCD backlight PWM inverter failure or capacitive touch controller firmware corruption after power surge or improper shutdown sequence during communication update.
- ✓ETUNG communication interface Modbus RTU repeated CRC checksum error or node timeout — RS-485 transceiver termination resistor burnt out due to reflection noise on poorly shielded industrial network. Secondary cause is firmware version mismatch or baud rate configuration corruption in EEPROM after brown-out reset.
- ✓ETUNG power supply module output voltage sag or ripple under load causing intermittent I/O failures — Electrolytic capacitor dry-out or internal ESR rise in harsh ambient temperature factory environment (>50degC), combined with output rectifier diode reverse leakage current.
- ✓ETUNG encoder interface board intermittent signal loss or amplitude attenuation on incremental sine/cosine output — Optocoupler in galvanic isolation circuit suffers LED brightness degradation under continuous vibration and thermal cycling. Preamp input bias current drift or offset voltage shifts reduce signal dynamic range over product lifetime.

Frequently Asked Questions — ETUNG Repairs
Do you repair ETUNG equipment anywhere in India?+
Yes. Synchronics repairs all ETUNG PLC modules, motion controllers, HMI terminals, communication cards, power supplies, and encoder interface boards across India. We offer scheduled pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, and Surat. All repairs are processed in our factory in Vadodara, Gujarat with factory-standard turnaround of 5-7 working days for standard module failure, or 2-3 days for critical downtime situations.
How do you diagnose ETUNG PLC CPU faults when the device shows no boot signs?+
Synchronics uses JTAG boundary scan interface and EEPROM programmer to isolate CPU databus and address bus short circuits, verify boot ROM integrity, and reflash configuration memory without opening the module enclosure. We perform voltage rail profiling across the main power distribution network and CPU power plane to identify regulator failures or capacitive load instability. If boot issue stems from backup battery failure, we replace the CMOS battery and restore real-time clock calibration.
What is your typical repair cost for ETUNG motion controller servo amplifier failure?+
ETUNG motion controller servo amplifier repairs at Synchronics typically range from INR 8,000 to 18,000 depending on fault severity. Capacitor replacement and output stage component rework costs INR 8,000-12,000. If power stage MOSFETs or integrated servo IC requires replacement, costs escalate to INR 15,000-18,000. We provide upfront diagnostic cost of INR 1,500 that is credited against repair if you authorize work. Spare parts are sourced from authorized distributors ensuring genuine ETUNG-compatible components.
Can Synchronics repair ETUNG HMI touch panels that have firmware corruption or display calibration loss?+
Yes. Synchronics has ETUNG HMI firmware archive and restoration tools to re-flash corrupted bootloader and application firmware via USB or serial interface. We perform capacitive touch calibration matrix reload and LCD backlight brightness adjustment using factory calibration profiles stored in flash EEPROM. If the LCD panel itself is faulty (dead pixels, backlight inverter failure), we source original ETUNG replacement panels or qualified industrial equivalents from authorized Indian distributors.
Do you offer on-site repair or troubleshooting for ETUNG production line equipment in Indian textile mills?+
Synchronics offers remote technical support and on-site diagnostics for critical ETUNG installations in textile spinning mills and packaging facilities. Our field service engineers can visit production floor to perform encoder signal quality assessment, power supply stress testing, and communication network diagnostics. For module-level repairs, we recommend depot service in Vadodara with rapid courier pickup to minimize downtime. We also provide ETUNG system documentation and PLC ladder logic review consultation for preventive maintenance optimization.
How do I send my ETUNG 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 ETUNG 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 ETUNG 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 ETUNG 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.
