GRANTECH Product Lines We Repair
Our engineers are trained on the full GRANTECH product range. Below are the major product families we service.
GRANTECH Control Systems (PLC/HMI)
Industrial controllers and human-machine interfaces managing granulation line parameters, feed rates, temperature zones, and cut timing. Common issues include firmware corruption, relay card failures, touchscreen malfunction, and communication protocol errors between main PLC and peripheral modules.
GRANTECH Motor Drive Systems
Frequency converters and soft-starters powering main granulator motors, extruder drives, and material feeder systems. Repairs address IGBT failures, DC bus capacitor degradation, overheating protection faults, and encoder signal loss in closed-loop speed control.
GRANTECH Hydraulic Control Electronics
Proportional valve drivers and pressure transducers regulating cutting force, material flow, and blade engagement in granulation chambers. Faults include solenoid coil burnout, proportional spool valve stiction, pressure sensor signal drift, and proportional amplifier card failures.
GRANTECH Temperature Management Systems
Multi-zone process temperature controllers managing heating bands, cooling jackets, and melt temperature regulation in extrusion and granulation processes. Common faults: thermocouple connector oxidation, SSR (solid state relay) thermal cycling failure, temperature sensing oscillation, and hysteresis in PID loop tuning.
GRANTECH Communication Modules (Fieldbus)
Profibus, CANopen, and Ethernet gateways connecting GRANTECH equipment to plant production monitoring systems and MES platforms. Issues include protocol timeout errors, gateway memory corruption, shielding cable degradation causing CRC failures, and node address conflicts.
GRANTECH Sensor and I/O Interfaces
Analog and digital input/output conditioning cards, proximity sensor amplifiers, and load cell signal processors. Repairs involve analog input noise filtering, sensor bridge imbalance correction, digital output relay coil replacement, and EMC shielding restoration.

Common GRANTECH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GRANTECH equipment arriving at our workshop.
- ✓GRANTECH PLC firmware corruption and boot failure — Power supply interruption during firmware update or flash memory degradation due to thermal cycling in harsh production environments. GRANTECH GCP series PLCs are susceptible to corrupted bootloader sectors when supply voltage drops below 18V during operation.
- ✓GRANTECH motor drive IGBT short-circuit and thermal runaway — Gate drive circuit instability, inadequate heatsink contact pressure, or environmental moisture ingress causing module leakage current. High dV/dt transients from long motor cable runs in Indian recycling plants trigger IGBT junction failures.
- ✓GRANTECH proportional valve driver solenoid coil open-circuit — Coil insulation breakdown from sustained high-temperature operation (>80C ambient), moisture ingress at connector pins, or transient voltage spike during PLC reset cycles. GHC-PRO proportional amplifier cards show elevated coil resistance trending 48-72 hours before complete failure.
- ✓GRANTECH temperature controller erratic PID oscillation and overshoot — Thermocouple terminal oxidation introducing noise into sensor loop, incorrect PID gain tuning for new heating band resistance, or failing proportional valve causing non-linear thermal response. Multi-zone GTM controllers show oscillation in downstream zones when zone 1 tuning drifts.
- ✓GRANTECH Profibus gateway timeout and node disconnection errors — Shielding degradation in CAT5 fieldbus cables running parallel to motor power lines (EMI coupling), termination resistor failure, or GFB gateway RAM memory corruption from repeated power cycles. Indian plants with 50+ granulation line stations experience cascading node failures.
- ✓GRANTECH load cell signal drift and zero-point creep in feeder systems — Analog signal conditioning card capacitor aging, cold solder joint on load cell bridge supply traces, or thermal coefficient mismatch between sensor and electronics causing calibration loss over 6-12 months. Indian humidity and temperature extremes accelerate drift rates.

Frequently Asked Questions — GRANTECH Repairs
Do you repair GRANTECH equipment anywhere in India?+
Yes. Synchronics repairs the full GRANTECH product range — granulation line controls, motor drives, hydraulic controllers, temperature systems, and fieldbus gateways. We offer pan-India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, and all other major cities. All repairs are performed at our 25000 sq-ft facility in Vadodara, Gujarat, with 7-10 day standard turnaround for non-warranty work.
What GRANTECH fault codes can you diagnose and repair?+
Synchronics resolves GRANTECH diagnostic codes across GCP, GFD, GHC, and GTM product families — including motor drive overcurrent faults (F01-F15), PLC communication errors (E20-E45), proportional valve response timeouts (H10-H25), and temperature sensor circuit failures (T01-T12). We maintain original GRANTECH fault code documentation and perform root-cause analysis using in-circuit testing rather than component swaps.
Can you repair GRANTECH equipment still under factory warranty?+
Yes. Synchronics is an authorized repair partner for GRANTECH warranty work in India. We coordinate directly with GRANTECH support for firmware releases, technical specifications, and warranty claim documentation. All repairs maintain warranty coverage; we do not void factory guarantees. Customers can elect factory direct repair or Synchronics repair with cost and timeline transparency.
How quickly can you repair GRANTECH granulation line controllers?+
GRANTECH PLC and HMI repairs typically complete in 5-7 working days for diagnostic, component replacement, firmware validation, and final pressure testing. Motor drive repairs (capacitor, IGBT, bridge) average 6-8 days including thermal cycling verification. Emergency express service available for critical production downtime — we can prioritize turnaround to 48-72 hours with premium service fees. We provide real-time status updates via portal access.
What testing and validation does Synchronics perform on repaired GRANTECH equipment?+
All GRANTECH repairs undergo multi-stage validation: (1) functional in-circuit testing and component parameter verification, (2) firmware integrity check and bootloader validation, (3) pressure/thermal response simulation under load on test rig, (4) full diagnostic code clearance and re-initialization, (5) 24-48 hour burn-in under simulated industrial duty cycle, and (6) final field calibration data download and lockout documentation. Complete test reports and serial number traceability provided.
How do I send my GRANTECH 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 GRANTECH 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 GRANTECH 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 GRANTECH 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.
