LIVE WIRE CHECK

State                                          Indication                                            

Live                                            Phase with L1, L2, L3, “ON” is live state

Missing line of earth line            LED doesn’t light up for missing line of earth line

Earth line (Delta connection)     Phase with flashing LED is an earth phase

Positive phase                          Green rotation LEDs flash in clockwise direction,                                                                                              and buzzer sounds intermittently. The circuit under test will have                                                                      forward rotation.

Reversed phase                       Red rotation LEDs flash in anticlockwise direction, and buzzer sounds                                                           continuously. The circuit under test will have reverse rotation.

Detect Indications                     Live phase L1, L2, L3 LEDs illuminated

                                                 Open phase Corresponding LED not illuminated

                                                 Correct phase sequence Green CW (clockwise)LED

                                                 Incorrect phase sequence Red CCW (counterclockwise)
