Emotron MSF 2.0 Softstarter

5. How to get startedThis chapter briefly describes the set-up for basic soft startand soft stop using the default “Torque control” function.WARNING! Mounting, wiring and setting thedevice into operation must be carried out byproperly trained personnel.5.1 Checklist• Mount the softstarter as set out in chapter 3. page 15.• Consider the power loss at rated current when dimensioninga cabinet, max. ambient temperature is 40ºC.• Check that the motor and supply voltage corresponds tothe values on the softstarter’s rating plate.• Connect the protective earth.• Connect the motor circuit according to Fig. 25.• Connect the control supply to terminals 01 and 02. Thecontrol supply voltage range is 100-240 VAC or 380-500 VAC, see rating plate.• Connect relay K1 (terminals 21 and 22 on the softstarter)to the contactor – the softstarter then controlsthe contactor (for factory configuration of K1).• Connect terminals 12 and 13 to, e.g., a 2-way switch(closing non-return) or a PLC and a jumper between 11and 12, etc., to obtain control of soft start/soft stop. (Forfactory configuration of digital inputs 1 and 2.)• Ensure the installation complies with the appropriatelocal regulations.5.2 ApplicationsWARNING! Make sure that all safety measureshave been taken before switching on thepower supply.Switch on the control supply voltage (normally 1 x 230 V);all segments in the display and the two LEDs will be illuminatedfor a few seconds. Then the display will show menu[100]. An illuminated display indicates there is control supplyvoltage to the softstarter unit. Check that you havemains supply voltage to the mains contactor or to the thyristors.The settings are carried out according as follows:PTCCurrent transformerDigIn 1 DigIn 2 +12 V AnIn GND DigIn 3 DigIn 4 +12 V AnOut CT1 CT2 CTc11 12 13 14 15 16 17 18 19 75 76 77Start/StopFig. 25 Standard wiring.Emotron AB 01-4135-01r2 How to get started 27
