RVS-AX Analogue Soft Starter Start Stop Parameters

Potentiometer settings for:

  • Motor Full Load Current (FLC)
  • Initial Voltage
  • Current Limit
  • Ramp-Up
  • Ramp-Down

Motor & Starter Protection

  • Electronic Overload - Inverse time Electronic Overload. Operational at end of acceleration process
  • Phase Loss - Operational when starter is energized and protects the motor from single phasing. Trips the starter when one or two phases are missing for more than 1 sec.
  • Heatsink Over Temperature Protection - A thermal sensor mounted on the heatsink trips the starter when the temperature rises.
  • Fault logic, Trip and Reset circuits. When a protection operates, the starter locks in fault mode, disabling thyristor firing, the LED indicates the fault, and the Trip contact closes
