The CM09 is a fully configurable automatic transfer switch control module. It is designed to monitor the incoming normal supply for loss of power. Should normal supply voltage fall out of limits the module will issue a start command to the generating set controller. Once the set is available and producing an output the ATS module will control the transfer devices and switch the load from the Normal to Emergincy power. Should the Normal supply return, the module will command a return to the Normal supply and shut down the generator after a suitable cooling run. Various timing sequences are used to prevent nuisance starting and supply breaks.
