GTI Product Lines We Repair
Our engineers are trained on the full GTI product range. Below are the major product families we service.
GTI ProLogic Controllers
Compact programmable logic controllers designed for discrete and process manufacturing. Common repair issues include CPU module failures, program memory corruption, real-time clock drift, and I/O card burnout from power surges or industrial interference.
GTI CompactNet Communication Modules
Industrial Ethernet and fieldbut gateway modules enabling PLC-to-device communication. Frequent faults include port connector corrosion, protocol stack crashes, packet loss under EMI, and firmware version mismatches causing handshake failures.
GTI PowerBase Supply & Distribution Cards
Redundant and single-phase power supply boards for control cabinets. Typical defects: capacitor bulk degradation, relay switching failures, voltage regulation drift, and thermal shutdown triggered by dust accumulation or cooling fan failure.
GTI AutroCard Advanced I/O Expansion
Modular analog and digital input-output cards with isolated channels for harsh environments. Repair challenges include analog channel noise, digital opto-isolator failure, ADC linearization errors, and screw-terminal contact oxidation.
GTI HMI Touch Panel Terminals
Industrial human-machine interface panels with resistive and capacitive touchscreen options. Common failures: display panel delamination, touch controller IC burnout, battery backup failure in data logging units, and firmware crashes causing frozen screens.
GTI CyberShield Industrial Firewalls
Network security appliances protecting PLCs and SCADA systems from cyber threats. Typical issues: SSL certificate expiration, packet filtering rule memory overflow, port filtering timeout, and firmware update failure leaving devices unbootable.

Common GTI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GTI equipment arriving at our workshop.
- ✓GTI ProLogic CPU module boot failure — Power supply voltage sag or supply-side harmonics damage CPU crystal oscillator or boot ROM interface. Program memory corruption from sudden power cuts before EEPROM write cycle completion also triggers this fault, leaving the controller unable to initialize POST (power-on self-test) sequence.
- ✓CompactNet Ethernet port packet loss and frame corruption — Industrial EMI from adjacent VFD cables induces transients on the twisted-pair Ethernet lines, corrupting RJ45 connector contacts and tripping internal surge protection diodes. Poor grounding of control cabinet shield can amplify EMI susceptibility, causing random layer-2 frame loss and DHCP renewal loops.
- ✓PowerBase 48V supply rail sag and thermal shutdown cycles — Electrolytic capacitor dry-out (common in Indian summers with ambient temps >45°C) reduces ripple filtering, causing 48V rail to sag below 46V minimum during high transient load. Thermistor sensors then trigger shutdown to protect downstream cards, creating intermittent brownout conditions and logic faults in connected modules.
- ✓AutroCard analog channel noise and ADC offset drift — PCB solder cracks in analog signal paths due to thermal cycling (temperature swings in uncontrolled industrial spaces) degrade signal integrity. Precision 20-bit ADC reference voltage IC degradation or capacitor dielectric absorption causes progressive offset error — reading 4-20mA signal as 4.5-21.2mA, throwing PLC calculations out of tolerance.
- ✓GTI HMI touch panel frozen display and unresponsive input — Touch controller IC overheating (due to blocked cabinet ventilation) combined with firmware watchdog timeout causes the display subsystem to hang. Resistive touchscreen delamination from humidity ingress (common in coastal and monsoon regions) also causes false touch events that flood the serial buffer and crash the UI task.
- ✓CyberShield firewall rule engine crash and unboot condition — Overly complex packet filtering rule sets (>500 rules) can exhaust the rule database memory on older CyberShield models, causing the kernel to panic and enter an unbootable loop. Failed firmware update — typically from corrupted download during power fluctuation — leaves the device stuck in bootloader mode.

Frequently Asked Questions — GTI Repairs
Do you repair GTI equipment anywhere in India?+
Yes. Synchronics repairs the complete GTI product portfolio — ProLogic controllers, CompactNet communication modules, PowerBase supply systems, AutroCard I/O expansions, HMI touch panels, and CyberShield firewalls. We offer PAN India door-to-door pickup from all metro cities (Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Kolkata) and smaller industrial towns. All repairs are centralized at our Vadodara facility with full diagnostic and burn-in capabilities.
What is the typical turnaround time for GTI ProLogic controller repair?+
Standard turnaround is 5-7 working days from receipt at our Vadodara facility. Complex cases involving CPU damage, memory corruption, or multi-module faults may extend to 10-14 days. We offer 24-48 hour express repair for critical systems (charge additional), and provide live status updates via your customer portal. All units include 12-month repair warranty and pre-delivery burn-in testing.
Can Synchronics recover program code from a corrupted GTI ProLogic memory?+
Yes, with caveats. If the EEPROM (backup program memory) is intact, we recover 100% of your application code. If both flash and EEPROM are corrupted, we can often retrieve partial code from the CPU die using specialized JTAG forensics, but this recovery rate depends on how severely the memory sectors were overwritten. We recommend maintaining current backups; our engineers can also help set up automated code version control on your development workstation.
Does your GTI repair service include firmware updates and security patches?+
Absolutely. As part of our standard repair workflow, Synchronics tests your unit against the latest GTI firmware release and applies critical security patches (especially for CyberShield firewall units). We maintain a curated library of stable, tested firmware versions and help you balance new features against operational stability. We do NOT auto-upgrade to bleeding-edge beta firmware without your explicit approval, as production environments require stability over cutting-edge features.
Why does my GTI ProLogic controller keep losing time on the real-time clock?+
GTI ProLogic units rely on a 32 kHz crystal oscillator for real-time clock (RTC) accuracy. Battery backup failure (typical age 5-7 years) is the most common cause — the RTC crystal oscillation stops when main power is lost, causing time loss. Second cause is crystal frequency drift due to mechanical vibration in high-vibration environments (near large motors or pneumatic presses). Synchronics replaces the backup battery, stabilizes the crystal circuit with improved damping, and can install a GPS synchronization module if precise time-stamping is critical for your process. Most clock drift issues are resolved with a battery replacement ($50-100 spare part cost).
How do I send my GTI 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 GTI 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 GTI 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 GTI 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.
