KAESER KOMPRESSOREN SIGMA CONTROL Equipment We Repair — By Category
KAESER KOMPRESSOREN SIGMA CONTROL Product Lines We Repair
Our engineers are trained on the full KAESER KOMPRESSOREN SIGMA CONTROL product range. Below are the major product families we service.
Sigma Control 2
Legacy 2-compressor sequencing controller with analog inputs and relay outputs. Common failures include power supply degradation, relay contact corrosion in humid Indian environments, and communication dropout with older Kaeser compressors.
Sigma Control 3
Advanced multi-compressor controller with Ethernet, energy monitoring, and predictive maintenance. Repairs focus on network card failures, SD card corruption storing configuration, and pressure transducer signal loss in dusty plant environments.
Sigma Control 4
Latest generation controller with cloud connectivity, IoT integration, and AI-driven load optimization. Issues include Ethernet port failures, power supply module degradation, and software licensing/update problems affecting remote monitoring.
Sigma Control HMI Integration Modules
Touchscreen and SCADA integration modules for Sigma Control systems. Common faults are display panel backlight failure, serial communication errors with PLC systems, and memory corruption affecting setpoint storage.
Sigma Control Pressure & Temperature Transducers
4-20mA sensor modules integrated with Sigma Control for real-time compressed air network monitoring. Repairs address 4-20mA output drift, connector corrosion in high-humidity facilities, and zero/span calibration loss.
Sigma Control Power Supply Units
24VDC regulated power modules supplying Sigma Control electronics and solenoid valves. Typical failures include capacitor aging in hot Indian summers, thermal shutdown under peak load, and voltage regulation drift.

Common KAESER KOMPRESSOREN SIGMA CONTROL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KAESER KOMPRESSOREN SIGMA CONTROL equipment arriving at our workshop.
- ✓Sigma Control display not responding or blank screen — In dusty Indian manufacturing environments, LCD backlight inverter circuits degrade from thermal cycling and contamination. Touchscreen connector corrosion can also interrupt serial communication between display and processor board.
- ✓Sigma Control loss of pressure setpoint readings — Pressure transducer 4-20mA signal wiring suffers corrosion at connector pins in humid compressor rooms. Signal conditioning circuit failure in the Sigma Control input card also causes zero output readings across all pressure sensors.
- ✓Sigma Control network card not communicating with Modbus/Ethernet devices — RJ45 Ethernet connector solder joints fracture due to vibration from adjacent compressor units. Firmware corruption in network interface chip prevents proper packet transmission or reception.
- ✓Sigma Control intermittent power supply shutdown during peak load — Electrolytic capacitors in the 24VDC PSU degrade rapidly in high-temperature compressor enclosures (35-45°C ambient typical in Indian plants). Voltage regulation circuit becomes unstable, triggering thermal shutdown thresholds.
- ✓Sigma Control SD card corruption—configuration and error logs lost — Power interruptions during SD card write operations corrupt the file system. Contamination from compressor oil mist entering vent holes can cause electrical shorts on the card slot.
- ✓Sigma Control sequential compressor startup failure—all units run simultaneously — Relay contacts in the solenoid valve driver stage oxidize or weld shut, preventing individual compressor enable/disable commands. Firmware sequencing algorithm bugs after incomplete software update can also cause this fault.

What happens if my Sigma Control loses configuration after power failure?+
Synchronics can recover and restore your Sigma Control configuration from corrupted SD cards or reprogram it from backup documentation. We maintain Kaeser configuration software and compressor network parameters on file. After repair, we test setpoints and sequencing logic on our test bench to confirm your compressor system will operate correctly when returned to your plant.
How long does a typical Sigma Control repair take at Synchronics?+
Most Sigma Control repairs—power supply failures, relay replacements, transducer recalibration—are completed in 3-5 working days. Complex issues like network card replacement or firmware corruption recovery may take 5-7 days. We prioritize Indian automotive and pharmaceutical customers. Door-to-door courier service is included in our repair pricing.
Can Synchronics help integrate Sigma Control with our existing PLC and SCADA systems?+
