When the power supply is applied, the relay switch- es to star position (pin 16) and the star period starts. At the end of the set time period, the relay returns to the neutral centre position and the set delay between star and delta position starts. At the end of the star to delta delay (adjustable from 50 to 130 ms), the relay switches in delta position (pin 18) and does not release until the power sup- ply is interrupted for at least 200 ms. If the power supply is inter- rupted for more than 200 ms before the star time period has expired, the relay does not operate and the time cir- cuit is set to zero. The relay is ready for a new time peri- od. Time Setting Upper knob: Setting of star time range Centre knob: Star time setting on r elative scale: 1 to 10 with r espect to the chosen range.
