🔹 Product Introduction
The SELCO S6100.0010 is a SIGMA S6100 S/LS module designed for generator synchronization, control, and load-sharing applications. The S6100 provides three-phase busbar monitoring, frequency stabilization, voltage stabilization, voltage matching, automatic or manual synchronization, and active/reactive load sharing. It works within the SELCO SIGMA system together with the S6000 IO/P module and can interface with conventional or electronic governors and automatic voltage regulators.
The module supports RS485 MODBUS communication and CAN Bus connectivity, making it suitable for generator control systems, marine power-management installations, and other applications requiring coordinated generator operation. SELCO documentation specifies a 24 V DC primary supply with a separate 24 V DC backup supply and a three-phase busbar measurement range of 63 to 690 VAC.

🔧 Troubleshooting & Common Problems
• No synchronization: Check phase-voltage measurements, frequency inputs, generator status, circuit-breaker signals, and synchronization settings.
• Generator will not share load correctly: Verify CAN Bus communication with the S6000, governor/AVR interfaces, load-sharing configuration, and parallel-line wiring.
• Incorrect voltage regulation: Check the AVR interface, voltage feedback, configured nominal voltage, and voltage-control parameters.
• Frequency instability: Inspect the governor connection and confirm the configured frequency-control parameters and PID settings.
• CAN communication fault: Check CAN-H, CAN-L, termination, wiring polarity, and communication with the associated S6000 module.
• MODBUS communication failure: Check RS485 A/B wiring, COM reference, communication settings, and the connected SCADA or PLC master.
⚠️ Safety Precautions
• Disconnect and isolate the generator system before wiring or removing the S6100 module.
• Treat all generator and busbar voltage terminals as hazardous electrical circuits.
• Verify that the actual busbar voltage is within the specified measurement range before commissioning.
• Use the specified 24 V DC supply and maintain the required backup-supply arrangement where applicable.
• Follow correct grounding and isolation practices. SELCO documentation specifically warns that incorrect COM-to-ground connections in marine SIGMA installations can cause system instability.
• Confirm phase sequence, voltage-sensing connections, governor/AVR wiring, and breaker control signals before enabling automatic synchronization.
