Backup generator control and monitoring system for KSL TV

Summary form only given, as follows. This is a backup generator monitoring and control system designed to meet the demands stipulated by KSL Television in Salt Lake City, Utah. The system must monitor 28 (up to 32) inputs including, but not limited to, voltages, currents, and frequency of all three phases at three different points, as well as engine conditions, and enunciate any problems. Analog normalization, A/D conversion and processing occurs at the generator site. The system uses an interactive remote display with “softkeys” and a simple back-lit LCD readout through use of an EIA-422 transmission line. Control is simple, and hardware-based in order to ensure absolute functionality and reliability. It is important to make the design of the monitoring station robust, but its operation must be simple to accommodate all skill levels of operators
