Relay
General
ERV-YU Star Delta 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 delta relay output and delta relay LED on. Till power is off, device keeps same.
