AOS SYSTEMS Product Lines We Repair
Our engineers are trained on the full AOS SYSTEMS product range. Below are the major product families we service.
AOS Programmable Logic Controllers (PLCs)
Modular PLC systems for discrete and process automation. Common repair issues include corrupted firmware, processor card failures, communication module degradation, and input/output card malfunctions affecting signal integrity in high-temperature industrial environments.
AOS Motion Control Modules
Real-time motion controllers for servo drive integration and axis synchronization. Frequent repair needs involve encoder feedback faults, PWM output failures, resolver card issues, and firmware version incompatibilities causing jerky motion or axis lockup.
AOS Communication and Networking Boards
Industrial Ethernet, DeviceNet, and Profibus gateway cards for factory floor integration. Repair challenges include port degradation from moisture ingress, protocol stack corruption, routing logic failures, and connector pin oxidation in humid industrial facilities.
AOS Real-Time I/O Expansion Modules
Distributed I/O racks for analog and digital signal acquisition across production lines. Common faults involve analog-to-digital converter errors, relay contact wear, optoisolator failures, and ground loop noise causing false alarm signals in pharmaceutical and food processing plants.
AOS Power Supply and Battery Backup Units
Redundant power conditioning and uninterruptible power supplies for critical automation systems. Repair issues include capacitor aging, voltage regulation circuit failure, battery charging faults, and thermal management problems under sustained industrial load.
AOS HMI Touch Panel Integration Cards
Display control and human-machine interface gateway modules. Common repair needs address LCD backlight driver failures, touchscreen signal processing faults, microprocessor crashes, and firmware corruption preventing operator interface responsiveness.

Common AOS SYSTEMS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AOS SYSTEMS equipment arriving at our workshop.
- ✓AOS PLC firmware corruption and processor halt — Power surges, abrupt power-offs during firmware updates, or memory cell degradation in AOS PLC-2000 series modules cause bootloader corruption. The processor enters safe state and will not initialize application code, leaving the entire automation system offline.
- ✓AOS motion controller encoder feedback signal loss — In textile mills and packaging lines, vibration and thermal cycling damage encoder connectors on AOS MotionWorks modules. Ground loop noise from proximity sensors corrupts the differential encoder signal, causing axis drift and servo faults without visible hardware damage.
- ✓AOS EtherGate communication module packet loss and retransmission loops — AOS EtherGate modules experience Ethernet port failures from industrial electromagnetic interference and cable damage. Port driver chips degrade, causing intermittent packet loss and retransmission storms that disable networked I/O synchronization across the production floor.
- ✓AOS analog I/O module ADC reading drift and false pressure alarms — In pharmaceutical manufacturing, temperature swings and moisture ingress cause analog-to-digital converter reference voltage drift on AOS 16-Channel Analog modules. Sensor calibration offset errors accumulate, triggering false high-pressure alarms that halt batch processing.
- ✓AOS UPS battery module charging circuit failure and backup time loss — Electrolytic capacitors in AOS PowerGuard and UPS charging circuits age in hot server rooms, reducing charging efficiency. Battery cells sulfate, and charge-sense circuitry fails, preventing automatic backup activation during power loss events.
- ✓AOS HMI touch panel display unresponsiveness and firmware crash loops — AOS HMI Controller modules experience touchscreen sensor noise from nearby radio frequency transmitters in food processing plants. Microprocessor watchdog timer resets occur, causing display freezes and repeated boot cycles that prevent operator access to machine controls.

Frequently Asked Questions — AOS SYSTEMS Repairs
Do you repair AOS SYSTEMS equipment anywhere in India?+
Yes. Synchronics Electronics repairs the complete AOS SYSTEMS product portfolio including PLCs, motion controllers, I/O modules, communication gateways, and HMI interfaces. We offer PAN India door-to-door pickup from all major manufacturing centers — Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, and beyond. Equipment is serviced at our fully equipped Vadodara facility and returned with comprehensive test reports.
What is typical turnaround time for AOS SYSTEMS PLC or motion controller repair?+
Standard AOS SYSTEMS repairs complete within 5-7 working days from receipt. Firmware corruption or I/O module repairs may require 3-5 days. Critical systems receive priority handling with same-day diagnostics and express return. We maintain buffer stock of common replacement ICs and modules to minimize waiting periods for Indian manufacturing clients.
Can you recover lost AOS PLC program code if the EEPROM is corrupted?+
Synchronics can often recover program code from backup memory sectors or residual data in the AOS PLC processor. We work with customers to restore logic from backup disks or rewrite critical automation sequences based on system documentation. If code is permanently lost, we assist in reverse-engineering ladder logic from field I/O behavior and process flow documentation.
Do you repair AOS MotionWorks servo controller boards with bad encoder channels?+
Yes. AOS MotionWorks modules frequently experience individual encoder input failures from vibration and connector fatigue. Synchronics isolates faults to the differential receiver IC or resolver circuit and replaces failed components. We verify encoder signal integrity across full motion range and validate servo loop stability before return.
What support do you provide for AOS SYSTEMS equipment integration in older Indian textile and chemical plants?+
Synchronics provides technical consultation on AOS SYSTEMS legacy equipment compatibility with modern industrial networks. We assess aging PLCs and motion controllers for firmware updates, network gateway additions, and sensor interface upgrades. Our engineers work on-site at textile mills and chemical facilities across India to minimize production interruption during equipment modifications.
How do I send my AOS SYSTEMS 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 AOS SYSTEMS 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 AOS SYSTEMS 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 AOS SYSTEMS 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.
