Overview The RVS-DX is a digital electronic soft starter, incorporating six SCR’s to start a three phase squirrel cage induction motor by supplying a slowly increasing voltage, providing soft start and smooth stepless acceleration, while drawing the minimum current necessary to start the motor. The RVS-DX is equipped with internal bypass relays initiated by its microprocessor control (on units 31-310 amps). Using the soft stop, the RVS-DX slowly reduces the motor voltage, thus softly stoppin

Physical Installation Location of the RVS-DX is important to achieve proper performance and normal operating life. The unit should be installed in an area where it will be protected from: • Direct sunlight, rain or moisture • Corrosive gases or liquids • Vibration, airborne dust or metallic particles When preparing to mount the RVS-DX, lift it by its base, never by the front cover. For effective cooling as well as proper maintenance, the RVS-DX must be installed on a flat, non-flammable verti

Built in Bypass After Acceleration The bypass after acceleration allows the RVS-DX to control the motor during starting and stopping for smooth, step-less acceleration and deceleration. However, once up to full voltage the RVS-DX is bypassed to reduce the watt loss. The RVS-DX incorporates internal bypass relays allowing current flow through the SCR’s only during the soft start process. At the end of the soft start, the built-in relays bypass the SCR’s and carry current to the motor. Upon st

Operating “Inside the Delta” Using the RVS-DX soft starter “inside the delta” reduces the required soft starter rating by 1.73 ( √3) factor. For example, for a 150 amp, 460 volt motor, the RVS-DX-170-D is selected to operate in standard “line” mode. However, for “inside the delta” mode (150 amp ÷1.73=87 amps), the RVS- DX-105-D can be selected, thereby, reducing cost and physical space in the application. The following programming parameters are disabled, once the ‘inside the delta’ is selecte
