Description
🔹 Product Overview
The SELCO S6100.0010 is a SIGMA Series Synchronization and Load Sharing Module designed for generator control and power-management applications. SELCO identifies the S6100 as the S/LS module within the SIGMA generator control and protection system, where it performs synchronization together with active and reactive load sharing functions.
The module monitors the busbar side of the generator system and provides control functions for generator synchronization, frequency stabilization, voltage matching, and load sharing. It is intended for integration with electronic governors and automatic voltage regulators, while manual control can also be implemented through external push buttons.

The SELCO SIGMA documentation identifies S6100.0010 specifically as the Synchronization and Load Sharing Module. Published SIGMA documentation specifies a 24 VDC isolated supply and an environmental range of -15°C to +70°C; the dimensions shown in the SIGMA documentation are 145 × 190 × 64 mm.
🔹 System Integration
The S6100 is normally used together with other SIGMA modules. The S6000 handles generator-side measurements and protection, while the S6100 performs synchronization and load-sharing control. Optional user-interface and power-management modules can be integrated into the overall system.
This architecture makes the S6100 useful for multi-generator installations where generators need to synchronize with the bus and then maintain balanced active and reactive power distribution.
🔹 Installation & Maintenance
Before installation, confirm the exact part number S6100.0010 and verify compatibility with the existing SIGMA system. Check the 24 VDC supply, wiring, governor interface, AVR interface, and busbar measurement connections before commissioning.
During maintenance, inspect terminal connections, power-supply stability, synchronization signals, governor/AVR control signals, and load-sharing behavior. If replacing an existing module, record the existing configuration parameters before removing the original unit so that the replacement can be configured consistently.
For generator paralleling applications, synchronization and load-sharing parameters should be verified during commissioning to prevent incorrect breaker-closing conditions or uneven generator loading.
