EWu – ON delay and the set interval. Independent settings of T1 and T2 intervals.
When the supply voltage U is applied, the set interval T1 begins. After the interval T1 has expired, the output relay R switches into on-position and the set interval T2 begins. After the interval T2 has expired, the output relay switches into off-position. If the supply voltage is interrupted before the interval T1+T2 has expired, the interval already expired is erased and is restarted when the supply voltage is next applied.
