Synchronizing Lights Module (1) Synchronizing lights. (2) Synchronizing switch.The synchronizing lights module is optional. The synchronizing lights module is located on the instrument panel (right side).The synchronizing lights module is not used when the panel is equipped with an electronic governor.Synchronizing lights (SL) are used as an aid for paralleling the generators that are independent of the load. Two lights are in the module. Each light is connected to the side with the load of the generator output circuit breaker. The voltage of two phases are measured. The lights are used to indicate to the operator when the voltages are in-phase. Close the circuit breaker now. The generator is on the line with the other generators.Note: For a complete explanation on the procedure to parallel two units, see the Operation And Maintenance Manual, SEBU6918, "Generators and Control Panels".
