AUTOMATICTRANSFER SWITCH GfiT AUTOMATICTRANSFER SWITCH GfiT ATC-100 CONTROLLER The ATC-100 is a comprehensive and multifunctional micropro cessor-based ATS controller. It is a compact and self-contained panel-mounted device that is designed to replace traditional relay and solid-state logic panels. The ATC provides both fixed and jumper-selectable settings to allow for a range of applications. It operates from all system voltages between 120 and 480 Vac, single-phase and three phase at 50 or 60 Hz. The ATC-100 monitors the condition of the three-phase line to lin e voltage and the frequency of both the utility and generator power sources. It can also be set up for single-phase operation. The ATC-100 provides the necessary intelligence to ensure that the transfer switch operates properly through a series of selectable sensing and timing functions FEATURES • Source 1 sensing: • Undervoltage / underfrequency • Overfrequency • Source 2 sensing: • Undervoltage / overfrequency • Controller settings via jumpers located at the rear of the unit • Mimic diagram with source available and connected LED indication • System test pushbutton • Plant Exerciser - Selectable day, off, 7, 14 or 28 day intervals with fixed 15 minute run time • Monitor utility and generator power source voltages and generator power source frequency • Provides undervoltage protection of the utility and generator power sources • Provides underfrequency and overfrequency protection of the generator power source • Permits easy customer setup • Permits system testing • In-phase transition
