1 Automation and Drives s SIRIUS 1 s SIRIUS Soft Starts

2 Automation and Drives s SIRIUS 2 s SIRIUS Soft Starts Topics –Definition of SIRIUS Soft Starts –Features & Benefits of SIRIUS Soft Starts –Applications of SIRIUS Soft Starts –How to use SIRIUS Soft Starts

3 Automation and Drives s SIRIUS 3 s SIRIUS Soft Starts From the Dictionary: –Sirius - Sir·i·us (sr-s) n.A star in the constellation Canis Major, the brightest star in the sky, approximately 8.6 light-years distant from Earth. Also called Dog Star, Sothis. [Latin Srius, from Greek Seirios, from seirios, burning.] Siemens definition of SIRIUS Soft Starts –Sirius - Sir·i·us (sr-s) n. A line of high quality soft starts for low hp applications, the brightest star in the sky.

4 Automation and Drives s SIRIUS 4 s SIRIUS Soft Starts Features & Benefits –Internally Bypassed >No external bypass necessary >No power loss or heat generation during periods of continuous operation –2 phase control >Provides optimal control of motors up to 60 hp >Reduces current and torque during start L1L2L3 M 3 ~

5 Automation and Drives s SIRIUS 5 s SIRIUS Soft Starts Features & Benefits –UL Listed –CSA Certified –CE mark

6 Automation and Drives s SIRIUS 6 s SIRIUS Soft Starts Features & Benefits –Compact Design >4 sizesw x h x d (mm) –S00 45 x 95 x 95 –S0 45 x 125 x 120 –S2 55 x 145 x 145 –S3 70 x 165 x 180

7 Automation and Drives s SIRIUS 7 s SIRIUS Soft Starts Features & Benefits –DIN rail mountable –Supply Voltage Ranges >3 phase, 50/60 hz, V >3 phase, 50/60 hz V –Wide control power range > V, 50/60 AC or DC (Standard) >24 V, 50/60 AC or DC (Optional)

8 Automation and Drives s SIRIUS 8 s SIRIUS Soft Starts Features & Benefits –2 LEDs for diagnostics –Two output relays for status indication (Sizes S0 –S3)

9 Automation and Drives s SIRIUS 9 s SIRIUS Soft Starts Features & Benefits –Designed for compatibility with other Siemens SIRIUS offerings –Recommended overload, Class 10, 3RB10 Solid State Overload –Compatible with 3RV10 MSP

10 Automation and Drives s SIRIUS 10 SIRIUS s SIRIUS Soft Starts Features & Benefits 3RW phase –Single Ramp Soft Start and Soft Stop –Independent adjustment for both Starting, Stopping and Initial Voltage –Single speed motor operation t Ran t USUS UNUN U t Raus

11 Automation and Drives s SIRIUS 11 SIRIUS s SIRIUS Soft Starts Features & Benefits 3RW phase - New –Single Ramp Soft Start –Independent adjustment for Starting Time and Initial Voltage –For Single Speed Motor Operation

12 Automation and Drives s SIRIUS 12 SIRIUS s SIRIUS Soft Starts Applications –When do I use SIRIUS Soft Starts? –Low duty cycle applications >Up to 10 starts per hours without de-rating >More than 10 starts per hour - contact technical support –Loads that will start up relatively quickly >Do not use on loads that take longer than 20 seconds to starts

13 Automation and Drives s SIRIUS 13 SIRIUS s SIRIUS Soft Starts Applications –Pumps >Avoidance of pressure surges >Prolonged life of piping system –Conveyor belts >Jolt free starting >Jolt free deceleration >Allows for lower grade belt material to be utilized

14 Automation and Drives s SIRIUS 14 SIRIUS s SIRIUS Soft Starts Applications –Agitators / Mixers >Reduced starting current –Fans >Gentle operation of gears and belts –Escalators >Eliminates the shock of an across the line start

15 Automation and Drives s SIRIUS 15 SIRIUS s SIRIUS Soft Starts Using a SIRIUS Soft Start –Control power supply to A2/A1 –Contact closure between A1/1 will cause the soft start to run –If the Soft Stop feature is used the soft start will automatically ramp the voltage down when the run signal is removed

16 Automation and Drives s SIRIUS 16 SIRIUS s SIRIUS Soft Starts Using a SIRIUS Soft Start – Offers three types of control: >pushbutton >switches >automatic start L N L1L2L3 T1T2T /23 A2A1 1 On Off start ended
