Operating mode Signalling is made by means of the front-face LED. LED Function Output contact closed R: yellow LED ABB

2 Function descriptions/diagrams Function diagram legend G Control supply voltage not applied / Output contact open / LED off B Control supply voltage applied / Output contact closed / LED glowing Phase sequence and phase failure monitoring If all phases are present with the correct phase sequence, the output relays energize after the start-up delay t s is complete. If a phase failure or a phase sequence error occurs, the output relays de-energize instantaneously. The LED R glows when the output relays are energized. In case of motors which continue running with only two phases, the detects phase failure if the reverse fed voltage is less than 60 % of the originally applied voltage.
