How it works

1The function (A or B) and the output 2 type are selected with the side DIP switch.
2The 120 min timing starts when the start contact closes, or on power-up if it is already closed.
3In function A, output 1 switches on after 120 min; in B, the output switches on at start and off at the end.
4The reset contact switches the output off and sets the time back to zero; after a power cut the cycle starts from zero.
