Product Description

General

FKV-14N phase failure relays are designed to avoid any failure of three phase motors caused from network.

Usage and Working Principle

Make the connections of the device in accordance with connection scheme.

Normal Operation (No Error): When the voltage are at normal values and the phase sequence is correct, the relay gets activated and the OUT LED is on.

Asymmetry Error: When any phase goes out of the normal range, the ERR LED flashes (at 2 second intervals), the OUT LED is off and the relay deactivated.

Relay is Activated: 2 (COM) and 3 (NC) short circuit, 1 (NC) and 2 (COM) open circuit.
Relay is De-activated: 2 (COM) and 1 (NC) short circuit, 1(NC) and 2 (COM) open circuit.

Maintenance
