Functions

  • Preset rotation direction for motor regardless from the sequence of input circuit phases
  • All standard types of protection for the motor
  • Regular check up if the motor is available by the actuator
  • Remote control over motor insulation resistance
  • Linking with the upper level computer through RS-485 interface with Modbus RTU and Profibus DP protocols
  • Shutting / opening the stop valve flow section upon the operator’s instruction
  • Motor automatic switch off when the stop fitting reaches end positions
  • Motor automatic switch off when the preset loads are overrun at the output element
  • Notice on motor automatic switch off is shown on the operator’s control panel
  • Local control (by local control panel) or keyboard
