AUTOMATICTRANSFER SWITCH ATC-300+ CONTROLLER The ATC-300+ is a comprehensive and multifunctional microprocessor-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-300+ Controller provides programmed flexibility to address the needs of any system. It operates from all system voltages between 120 to 600V, single-phase and three-phase at 50 or 60 Hz. In addition, a period of no control power is provided. The controller monitors the cond ition of the three-phase line-to-line voltage and frequency of Source 1 and Source 2 power sources and can be programmed for single-phase operation. The ATC-300+ Controller provides the intelligence to ensure that the ATS operates properly through a series of programmed sensing and timing functions. FEATURES • Auxiliary relay contacts: • Source 1 present 2NO and 2NC • Source 2 present 2NO and 2NC • Source 1 and source 2 sensing: • Undervoltage / underfrequency • Overvoltage / overfrequency • Three-phase rotation protection • Three-phase voltage unbalance/loss • Pre-transfer signal contacts 1NO and 1NC • Go to emergency (Source 2) • Seven field-programmable time delays • LCD-based display for programming, system diagnostic and help message display • Mimic diagram with source available and connected LED indication • Time-stamped history log • System test pushbutton • Programmable plant exercise (off, daily, 7,14 and 28 day) interval selectable run time 0-600 minutes no load/load with fail-safe • Integral overcurrent protection (optional) • In-phase transition • Stainless steel cover for controller (optional) • Communications via RS-232 or Modbus through an integrated RS-485 port (optional)
