SIRUS CONTROLS PVT LTD Equipment We Repair — By Category
SIRUS CONTROLS PVT LTD Product Lines We Repair
Our engineers are trained on the full SIRUS CONTROLS PVT LTD product range. Below are the major product families we service.
Sirus VFD (Variable Frequency Drive) Range
Energy-efficient AC motor drives for pump, fan, and compressor applications. Common repairs involve firmware corruption, DC bus faults, and IGBT module failures from thermal cycling in Indian industrial environments.
Sirus Soft Starter Controllers
Electronic soft-start modules for reducing inrush current and mechanical stress on motors. Frequent issues include thyristor gate drive failures, current sensing circuit faults, and parameter loss due to power surges.
Sirus Industrial PLC Systems
Compact and scalable programmable logic controllers for textile looms, cement rotary kilns, and process automation. Common faults include I/O card burnout, communication module failures, and memory card corruption.
Sirus HMI (Human Machine Interface) Panels
Touchscreen and fixed-display operator panels with Modbus and Profibus connectivity. Repair challenges include LCD panel degradation, capacitor failures, and firmware version mismatches affecting industrial communication protocols.
Sirus Control Cabinets & Panels
Pre-assembled automation panels with integrated Sirus controllers, soft starters, and protection circuits. Issues often stem from component thermal stress, loose connections, and relay contact wear in high-vibration Indian factory environments.

Common SIRUS CONTROLS PVT LTD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SIRUS CONTROLS PVT LTD equipment arriving at our workshop.
- ✓Sirus VFD DC Bus Over-Voltage Fault (F07 Error) — Regenerative braking energy feedback exceeds capacitor tolerance, or rectifier diode failure in the supply converter stage. Common in Indian plants with poor power quality and frequent supply voltage spikes.
- ✓Sirus Soft Starter Thyristor Gate Drive Failure — High dV/dt transients from industrial power distribution trigger thyristor gate circuits to malfunction. Indian grid disturbances and inadequate phase-shifting transformer isolation accelerate this degradation.
- ✓Sirus PLC I/O Card Short Circuit (Burnout) — Mis-wired field sensors or transducers apply incorrect voltage levels to input circuits. Indian installation practices sometimes bypass isolating relays, exposing PLC boards to 24V DC or AC supply damage.
- ✓Sirus HMI LCD Display Degradation & Pixel Loss — Extended operation in high-temperature Indian foundries and textile plants degrades LCD crystal alignment. Thermal cycling and humidity ingress shorten display lifespan to 3-5 years in tropical climates.
- ✓Sirus PLC Memory Card Corruption (Program Loss) — Sudden power failure or battery-backed RAM depletion causes program memory to become inaccessible. Indian sites with erratic power supply experience frequent data loss without UPS protection.
- ✓Sirus VFD Encoder Communication Timeout — Loose twisted-pair encoder cable connections or EMI interference from nearby power cables disrupt feedback signals. Cable routing near induction furnaces or welding equipment induces noise in Indian heavy industries.

Frequently Asked Questions — SIRUS CONTROLS PVT LTD Repairs
Do you repair Sirus Controls equipment throughout India?+
Yes. Synchronics repairs the complete Sirus Controls product portfolio including VFDs, soft starters, PLCs, HMI panels, and control cabinets. We offer PAN India door pickup from Vadodara, Mumbai, Delhi, Bangalore, Chennai, Hyderabad, Pune, Ahmedabad, and 50+ other cities. All repairs are processed in our Vadodara, Gujarat facility with factory-equivalent testing and 12-month warranty.
What is the turnaround time for Sirus VFD or soft starter repair?+
Standard non-urgent repairs typically take 5-7 working days from receipt. For critical plant downtime situations, Synchronics offers 24-48 hour expedited repair with priority diagnostics. We stock common Sirus components including capacitor banks, IGBT modules, and control cards for faster replacement. Emergency repair requests should include plant production impact details.
Can you repair Sirus PLC controllers with custom ladder logic or firmware modifications?+
Yes. Synchronics has expertise restoring modified Sirus PLC firmware, backing up existing program logic, and re-commissioning controllers after repair. We can extract program code from corrupted memory, test logic functionality in offline mode, and restore controllers to operational state. If original program is lost, we can help rebuild basic I/O sequences based on your process description.
Why do Sirus soft starters fail frequently in Indian textile and cement plants?+
Sirus soft starter thyristor gates are sensitive to high-frequency noise and voltage transients common in Indian industrial power distribution. Cement kiln variable loads, textile loom starting surges, and grid disturbances cause thermal cycling stress on gate drive circuits. Synchronics recommends installing phase-isolation transformers, adding suppression capacitors, and scheduling preventive component replacement every 4-5 years in high-stress environments.
How much does Sirus Controls equipment repair typically cost?+
Sirus repair costs vary by equipment type and fault severity. Simple soft starter gate card replacement: Rs 4,000-8,000. VFD capacitor bank replacement: Rs 8,000-15,000. Full PLC rebuild with memory recovery: Rs 10,000-20,000. HMI LCD replacement: Rs 6,000-12,000. Synchronics provides free diagnostic reports with cost estimates before proceeding. Many repairs are cost-effective versus new equipment purchase, especially for PLCs and controllers.
How do I send my SIRUS CONTROLS PVT LTD 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.
What is the cost of repairing a SIRUS CONTROLS PVT LTD 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 SIRUS CONTROLS PVT LTD 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 SIRUS CONTROLS PVT LTD 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.
