Introduction And Application
AMR1 has been designed for the control of emergency and standby power systems. It integrates the functions of engine start / stop relay, engine and alternator supervision and annunciator. The relay has a user friendly MMI in the form of a keypad and a LCD display. The engine start / stop relay element allows the automatic starting of relay when power fails, automatic stopping of the engine when mains return and also the control and interlocking of mains and DG Circuit Breakers. It also includes delayed supervision of oil pressure switch.
