    Tips: ATS Modes of Operation

    • Manual. Transfer initiation and operation are performed manually, typically by pushing a button or moving a handle; initiation occurs locally.
    • Non-automatic. Manually initiate a transfer by pressing a button or rotating a switch to cause an internal electromechanical device to electrically operate the switching mechanism; initiation can occur locally or remotely.
    • Automatic. Transfer switch controller is self-acting and completely manages both initiation and operation; initiation is triggered when the automatic controller senses an unavailability or loss of source power followed by operation of the switching mechanism.
