G11-140 (Model RXT Automatic Transfer Switch) 4/16d Page 2 Optional Combined Interface/Load Management Board The RXT transfer switch is available with either a stare interface board or a combined interface/load manager board. The combined board allows loads management described below. Load Management • The combined load management board disconnects non -critical loads to prevent generator overload, in compliance with NEC. • The combined load management board monitors gei current and frequency to determine when to add or loads. This monitoring prevents frequency drops thz damage valuable electronics like computers and WE • Load management allows the use of; a smaller gene) Operation • Loads are automatically added or shed based on gei capacity. • The load control system uses dynamic logic to prevE shedding important loads unnecessarily when air conditioning, refrigerator, or water pump motors start (patent pending). • The load management board and generator commw provide smart power management., The time to shei decreases as each load is shed to quickly adapt to c power requirements. • Load shed power level and frequency setpoints can adjusted using a personal computer (laptop) and Kol SiteTech- software, which is only available to Kohlel authorized distributors and dealers Load Shed Specifications Priority Setting • Loads are added and shed according to their priority. Load 1 is the top priority, which is added first and shed last. Load 6 is the lowest priority. • Less critical loads can be turned off automatically when essential appliances are running. • Load priorities are hard -wired at installation. Viewing Load Shed Outputs with OnCuee ;rator Pius ed can • Use Kohler's OnCue© Plus Generator Management System isions. (sold separately) to view load status (On or Off) for loads for set. connected to the load shed relays. • Use OnCue® Plus to remotely monitor when loads are shed or added. ;rator • The load shed outputs can be labeled in OnCues Plus. t Current Transformer • The combined load management board option includes a 400 amp current transfomer (CT) for load monitoring. • A larger diameter CT is available for applications that require cate to larger cables. loads • A 500 amp CT is available for use with a 60RCL generator. tical • See the table below for current transformer specifications and optional kit numbers.
