ARD Product Lines We Repair
Our engineers are trained on the full ARD product range. Below are the major product families we service.
ARD Proportional Directional Valves
Electro-hydraulic directional control valves with integrated electronics and spool feedback. Common failures include solenoid coil burnouts, spool stiction, and amplifier card failures. Repair requires coil rewinding capability and electronics recalibration.
ARD Servo Amplifiers and Controllers
Multi-axis servo drive systems for precision motion control in textile looms, injection moulding, and press applications. Failures include capacitor degradation, gate driver faults, encoder interface loss, and firmware corruption.
ARD Proportional Pressure Reducing Valves
Pressure regulation systems with electronic feedback and real-time load sensing. Common issues include pilot stage leakage, proportional solenoid drift, and control electronics EEPROM failure.
ARD Compact Logic Controllers (CLC)
Embedded PLC modules for valve sequencing and machine automation. Repair focuses on relay contact wear, input/output transistor failure, communication module faults, and program memory loss.
ARD Pressure Transducers and Feedback Systems
4-20mA and 0-10V industrial pressure sensors with ceramic sensing elements. Failures include bridge circuit imbalance, sealed connector corrosion, and output amplifier drift in humid or washdown environments.
ARD Custom Electronic Assemblies
OEM-specific custom control boards and interface modules for machine builders and system integrators. Repair involves schematic reverse-engineering, component-level troubleshooting, and custom firmware reload.
Why Choose Synchronics for ARD Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on ARD equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common ARD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ARD equipment arriving at our workshop.
- ✓Proportional solenoid coil burnout and open circuits — ARD solenoids exposed to moisture ingress, voltage spike transients from unprotected switching circuits, or chronic over-temperature in confined valve manifolds. Indian plant environments with high humidity and dust promote premature coil failure.
- ✓Amplifier card spool feedback signal loss or drift — ARD servo amplifier LVDT or Hall effect sensors degrade due to vibration, connector oxidation, or EMI interference from adjacent power cables. Common in plastics and textile machinery with poor cable routing.
- ✓Pressure transducer output erratic or non-responsive — ARD pressure sensors exhibit bridge imbalance, amplifier stage saturation, or sealed connector water ingress. Humid Indian coastal and industrial zones accelerate corrosion inside sensor headers.
- ✓PLC module power supply failure and no boot — ARD compact logic controllers suffer capacitor degradation (especially electrolytics in 40-50°C ambient), rectifier diode failure, and voltage regulator burnout. Indian power supply instability and unfiltered mains accelerate failures.
- ✓Encoder or resolver interface module intermittent or stuck — ARD servo encoder connectors suffer contact resistance build-up, differential line driver IC failure, or firmware handshake timeout. Vibration loosens M12 connectors on machine tools and injection presses.
- ✓EEPROM program memory corruption and parameter loss — ARD proportional valve controllers lose program and tuning parameters after power loss without proper UPS backup, or due to firmware update interruption. Flash memory cell degradation occurs after 5-8 years in tropical climates.

Frequently Asked Questions — ARD Repairs
Do you repair ARD equipment anywhere in India?+
Yes. Synchronics repairs the full ARD product range including proportional valves, servo amplifiers, PLC modules, pressure transducers, and custom control assemblies. We offer same-day collection from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, and all major Indian cities via scheduled courier or urgent air logistics. All repairs are completed at our ISO 9001 certified facility in Vadodara, Gujarat, with full test reports and one-year warranty.
What is your turnaround time for ARD proportional valve repair?+
Standard ARD proportional valve repair (coil burnout, spool stiction, amplifier failure) takes 5-7 working days including solenoid rewinding, electronics diagnostics, component replacement, and full pressure cycle testing. Urgent 24-48 hour express repair is available for critical production stops at Synchronics Vadodara facility. Custom tuning and parameter re-commissioning add 1-2 days if your specific solenoid impedance or pilot pressure ratios require factory configuration.
Do you carry ARD spare parts in stock or source them?+
Synchronics maintains stock of high-turnover ARD components including solenoid coils, proportional spool assemblies, pressure transducer sensors, capacitors, and servo amplifier ICs. We source ARD spare parts directly from authorized distributors and can arrange expedited shipping for critical components. For obsolete ARD equipment from 1990s-2000s, we perform reverse-engineering and component substitution where direct spares are unavailable.
Can you repair ARD servo amplifiers with encoder or resolver feedback loss?+
Yes. ARD servo amplifier encoder interface failures (intermittent commutation, position loss) are frequent in textile looms and injection press applications. Synchronics performs differential line driver IC replacement, encoder connector restoration, signal integrity testing on oscilloscope, and firmware re-flash. We validate closed-loop servo tuning with live motor load to ensure stability before handoff.
What if my ARD equipment has custom firmware or proprietary parameters?+
Synchronics extracts and backs up your original firmware before any repair work. We maintain firmware libraries for standard ARD product families and assist in parameter recovery for custom applications. If your machine requires field re-commissioning post-repair (pressure calibration, solenoid current trimming, servo loop gains), our engineers provide on-site support across India or remote guidance via video conferencing.
How do I send my ARD 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 ARD 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 ARD 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 ARD 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.
