Clock-pulse generator time delay relay MFT IT14S Function descriptions TP - Cycling timer relay beginning on a pause When the supply voltage U is applied, the set interval t1 begins (green LED U/t flashes slowly). After the interval t1 has U LED U/t R t1 t2 t1 t2 expired, the output relay switches into on-position (yellow LED illuminated) and the set interval t2 begins (green LED U/t flashes fast).
