The switches are 3 cycle rated to ease breaker selection and coordination. The mechanism is field proven and operated via a reliable, compact solenoid for high speed transfer of loads between power sources. The contacts are silver composite for long life, resisting pitting or burning. The switches are rated for full load transfers in critical operating, emergency, legally required, and optional power systems. Typical bypass isolation switch controllers only control the TS contactor. Generac s design allows the switch controller to remain active in both the TS and bypass modes, thus providing control to either contactor. This ability of the controller to remain active and control the bypass isolation contactor provides N+1 redundancy of a second fully functioning TS. The control s 4.3 inch color display and mimic bus diagram simplifies programming, routine operation, data presentation, and setting adjustments. The intuitive, grouped data screens along with the supervisory and highly customizable data acquisition allow the user to configure to their needs. Standard features include Modbus RTU, extensive user customizable input/ outputs, 450 event log with capture for the most recent 12 events, with 3 phase sensing on both sources, plus load for voltage, frequency, sequencing, loss, and unbalance. n automatic closed transition transfer switch (make-before-break) requires the normal and emergency sources to be synchronized. The controller monitors the voltage and frequency of both power sources with an anticipitory algorithm; phase angles must be within 8 electrical degrees. synchronization timer is initiated (TST, 1-60 min adjustable) to complete the transfer and parallels 100ms or less. If the TST times out and the transfer switch has not reached synchronization, the transfer switch will remain connected to the current Source, and a failure to transfer alarm will be displayed. The switch can also be configured to operate in open transition mode if there is a fail to transfer in closed transition.
