Set in a compact 72 x 144mm DIN standard case, the ATS740 is purpose designed to operate with contactors or motorised circuit breakers in automatic mains failure (A.M.F) applications where no DC supply is present. As the unit is AC powered from either the Mains or the Alternator, at the point of Mains Failure (engine not running) the unit is not powered! Thus, a True Delay on Disconnect Start Timer incorporating a magnetically latching RUN relay is employed. This provides a simple 2 wire (volt-free) connection to a remote mounted engine controller. If the RSM72 Remote Start Module is employed, it can easily operate at distances in excess of 100 metres. The front panel has nine High Intensity LED’s to indicate mains, alternator & system status. The mode switch selects Plant Off (Stop), Auto, Test off Load & Test on Load. All user adjustable timers and level potentiometers are accessible at the rear of the unit.
