When power supply is applied, the relay is switched to star position (pin 4) and the star time period starts. At the end of the set time period, the relay returns to neutral centre position and the fixed delay between star and delta starts. If power supply is interrupted during the star time period for min. 250 ms, the star time period is repeated. If power supply is interrupted after the star time period for at least 900 ms, the entire sequence is repeated. Power supply Accessories Time-ranges for star-position DIP-switch selector (1 & 2).
