ROLLS-ROYCE Equipment We Repair — By Category
ROLLS-ROYCE Product Lines We Repair
Our engineers are trained on the full ROLLS-ROYCE product range. Below are the major product families we service.
ACTIVE (Advanced Control and Turbine Integrated Electronics)
Rolls-Royce ACTIVE is the next-generation control system for industrial gas turbines, managing fuel injection, combustion sequencing, and turbine load optimization. Common issues include sensor signal degradation, fuel control unit failures, and synchronization errors in multi-unit installations.
SPAC (Supervisory Plant and Control)
SPAC systems provide supervisory control and data acquisition for large-scale power generation and marine propulsion installations. Typical faults include Ethernet communication module failures, logic processor errors, and operator interface touchscreen malfunctions.
HYDROMECHANICAL FUEL CONTROL UNITS (HFCU)
HFCU units regulate fuel flow to Rolls-Royce industrial turbines based on temperature, pressure, and load signals. Repairs commonly involve valve seat erosion, pressure transducer drift, and hydraulic amplifier poppet stiction.
REMOTE TERMINAL UNITS (RTU) and I/O MODULES
RTUs interface Rolls-Royce turbine control systems with plant SCADA networks. Faults include relay chatter, analog input card calibration drift, and ModBus communication timeouts in industrial environments.
COMBUSTION SAFEGUARD SYSTEM (CSS)
The CSS monitors flame detection, ignition sequencing, and combustion stability in Rolls-Royce gas turbines. Issues arise from flame sensor fouling, ignition transformer failures, and cross-wiring in control cabinets.
SPEED AND LOAD GOVERNOR ELECTRONICS
Governor systems maintain constant turbine speed and synchronized load sharing in multi-turbine power plants. Common failures include speed sensor malfunctions, proportional valve coil burnout, and feedback loop instability.

Common ROLLS-ROYCE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ROLLS-ROYCE equipment arriving at our workshop.
- ✓ACTIVE fuel trim offset error during startup — Fuel control unit pressure transducers accumulate carbon deposits in high-temperature environments, causing inaccurate trim commands. The ACTIVE system interprets this as a fuel system malfunction and holds the turbine in cranking mode.
- ✓SPAC Ethernet communication timeouts and master-slave synchronization loss — Industrial EMI and harmonic distortion in power-dense Indian manufacturing facilities degrade Ethernet module signal integrity. Faulty termination resistors or corrupted switch firmware can prevent proper packet transmission between supervisory and local controllers.
- ✓Flame detection circuit malfunction in CSS — false flame-out trips — Combustion safeguard flame sensors (UV or IR type) become contaminated with fuel deposits and ash, reducing signal strength below the detection threshold. Cross-wired or degraded ignition transformer windings also cause intermittent flame signal loss.
- ✓HFCU proportional valve spool stiction — erratic fuel flow response — Rolls-Royce hydromechanical fuel control units operate in harsh thermal and pressure conditions. Fuel degradation, water contamination, and particle ingress cause the proportional valve poppet to stick, making fuel trim commands lag or fail entirely.
- ✓Governor speed reference signal dropout — load runaway — Speed sensors (proximity or optical) degrade in hot turbine environments or suffer cable abrasion in crowded cable trays. Loss of speed feedback causes the governor proportional valve to command maximum fuel flow, risking turbine overspeed and shutdown.
- ✓I/O module relay chatter and intermittent contact welding — In Indian power plants with poor power quality, voltage spikes and harmonic distortion cause relay coils to vibrate excessively. Arcing across contact points leads to erosion, welding, and intermittent signal transmission to the control system.

Frequently Asked Questions — ROLLS-ROYCE Repairs
Do you repair Rolls-Royce equipment anywhere in India?+
Yes. Synchronics repairs the full Rolls-Royce industrial electronics range across India — ACTIVE gas turbine controls, SPAC supervisory systems, combustion safeguard electronics, and fuel control units. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Nagpur, and all other metropolitan areas. All repairs are completed at our ISO 9001 certified facility in Vadodara, Gujarat, with same-day dispatch on completion.
What is the typical repair turnaround for a Rolls-Royce ACTIVE control system failure?+
Standard turnaround for ACTIVE system repair is 5-7 business days depending on fault complexity. Critical repairs on site at power plants can be prioritized to 48-72 hours. Synchronics maintains a stock of common ACTIVE modules (fuel control cards, speed reference modules, and load controller boards) to enable rapid hot-swap while the failed unit undergoes bench diagnostics and repair.
Can Synchronics repair Rolls-Royce equipment under warranty without voiding manufacturer support?+
Yes. Synchronics is an authorized independent service center recognized by Rolls-Royce for industrial equipment repairs in India. We use genuine Rolls-Royce spare parts, follow OEM repair procedures, and issue full technical documentation and warranty certificates for all repairs. Your Rolls-Royce manufacturer warranty remains intact; we never breach seals or remove identification markings.
What causes flame detection system false trips in Rolls-Royce gas turbines?+
Rolls-Royce combustion safeguard systems (CSS) detect flame using ultraviolet or infrared sensors. False trips typically occur when sensor lenses become coated with fuel deposits and ash, reducing signal strength below the detection threshold. Cross-wired ignition transformers, faulty signal conditioning amplifiers, and degraded sensor cable insulation also cause intermittent flame-out errors. Synchronics cleans and bench-tests all CSS sensors and wiring, and validates the complete ignition circuit before returning the turbine to service.
How do I know if my Rolls-Royce SPAC supervisory system has an Ethernet communication problem?+
Common indicators are intermittent loss of remote terminal unit status updates, synchronization errors in multi-unit power plants, and SCADA system timeouts. You may see error codes in the SPAC operator display like 'Node Timeout' or 'Slave Not Responding'. Synchronics uses industrial protocol analyzers to diagnose Ethernet module failures, switch firmware corruption, and network configuration issues. We test repaired systems on our bench network simulator before return to ensure stable communication under real plant conditions.
How do I send my ROLLS-ROYCE 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 ROLLS-ROYCE 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 ROLLS-ROYCE 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 ROLLS-ROYCE 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.
