Multifunctional clock-pulse generator relay MFT ST22S Function descriptions TP - Cycling timer relay beginning on a pause When the supply voltage U (K1 closed) is applied, the set interval t1 begins (green LED U/t flashes slowly). After the interval t1 has expired, the output relay R switches into onposition (yellow 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).

Multifunctional clock-pulse generator relay MFT ST22S Function descriptions I3 - Pulse detection When the supply voltage U (K1 closed) is applied, the set interval t1 begins (green LED U/t flashes slowly) and the output relay R switches into on-position (yellow LED illuminated). After the interval t1 has expired, the set interval t2 begins (green LED U/t flashes fast). For the output relay to remain in on-position, the control contact K2 must be closed and reopened within the set interval t2.
