Features

• Displaying  grid’s voltage,error and adjustment messages
• Protection:
  • Over voltage/under voltage
  • Phase sequence and asymmetry
  • Phase loss
•  Indicators:
  • REL: relay connect
  • F: phase loss
  • P: phase sequence
  • On Delay-Off Delay: delay for connection and disconnection
  • Over-under: voltage increase and decrease
  • Unbalance: phase asymmetry

(Note: All indicators blinking: phase and neutral inversion)

• Adjustable protection parameters
• Phase neutral reversal warning
