The SmartWire-DT panel wiring system negate the need for conventional control wiring, using instead plug-in connections that make wiring errors almost impossible.The complete DS7 range, which covers power ratings from 1.5 kW to 110 kW at 400V, is available in versions that incorporate SmartWire-DT interfaces. In all cases, the SmartWire-DT connection allows start-stop control of the soft starter, provides the control supply, and allows read/write access to key operating parameters.In addition, the soft starter can transmit diagnostic data and status messages via the SmartWire-DT connection, and this information can be accessed either by the control system or, without taking the soft starter out of service, by a laptop computer as an aid to commissioning and servicing.All Eaton DS7 soft starters incorporate a patented asymmetrical trigger control technology which eliminates the dc components in the motor current that are produced by conventional two-phase controlled soft starters. This allows the motor to start more smoothly and with less vibration, and start-up times can be minimised.
