When power is applied the relay energises after approx. 1 second. The unit will only operate if all 3 phases are present and in the correct sequence. The unit is also sensitive to excessive phase imbalance. The Relay LED will illuminate when phases are in the correct sequence. If not, swop any 2 phases connected to terminals 5, 6 + 7 to obtain the correct phase sequence, which will then be confirmed by the illumination of the LED. A Phase Failure Phase Sequence Relay is also available with Neutral monitoring (PFPSR+N).
