The Russelectric® RPTCS microprocessor automatic transfer control system controls all operational functions of the ATS. Each RPTCS is programmed at the factory to control customer-specified options as well as standard switch features.
Setup, alarm acknowledgement, and review of actual data are easily accomplished using the controller’s soft keys and VGA color display. The intuitive, interactive menu guides the user through controller setup and the entering of configuration data, including communications and timing setpoints, adjustable control parameters (interlocks, alarms, and security), and event logging.
Real-time metering of voltage (phase-to-phase and phase-to-neutral) and frequency of both sources is standard, and metering of current and power is available. The RPTCS can also monitor power quality with available waveform capture and historical trending. All metering can be accessed through the menu.
The controller senses Source 1 (usually the electric utility source) and Source 2 (usually the engine generator source) voltages and, by means of easy-to-see LEDs, indicates switch position and source availability. Through the menu, the user can also review operational data such as active time delays, transfer inhibits, metered values, fault and alarm reports, event records, and configuration settings. The controller also automatically displays the status of monitored conditions in color-coded banners at the top of the VGA screen including faults and alarms, inhibits, and informational messages.
The RPTCS controller supports two communication interfaces: standard Modbus RTU or available Modbus TCP/IP via 10/100 Base-T Ethernet. An external USB communication port on the controller’s faceplate allows fast, easy connection to a laptop.
Access RPTCS Control Remotely Through the Web
Controller design accommodates the addition of accessories, including the DTWG Web Server Communications Gateway. With the DTWG Gateway, the RPTCS can also accommodate web-based digital and analog I/O serial communications over industrial fieldbus networks using other protocols.
