Multifunction clock-pulse generator relay MFT ITU24S 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 illuminated) and the set interval t2 begins (green LED U/t flashes fast). After the interval t2 has expired, the output relay switches into off-position (yellow LED not illuminated).
