The ASCO Group G microprocessor controller features an integrated one-line diagram, configurable relay outputs and modular accessories. The self-contained controller accommodates open or delayed transition transfer operation in automatic and non-automatic configurations. Multiple-source sensing capabilities comprise voltage, frequency (including under frequency sensing on normal and emergency sources), optional current card, and single- and 3-phase sensing, which does not require an external metering device. Additional features include a 128*64 integrated graphical LCD display with a soft keypad, six LED indicators, current measurement, ATS status and time delays, event logging, and a multi-lingual user interface for configuration and monitoring.
