Relays
General
ERV-YU Star Relay is designed to controll three phase motors in the start.
Usage and Working Principle
Make connections according to the diagram.You can set working time between 1-30sec.When power is on, star relay output and star relay LED on. Device waits for aoutputdjusted star working time and waits for adjusted time(1msec-500msec). In this position, there is no output contact and star relay led switches off. After waiting time relay output and relay LED on. Till power is off, device keeps same.
