How it works

1With the unit de-energised, the time base (1 s or 1 min) and the function are selected with the side DIP switch.
2The percentage of ON time is programmed with the two push-buttons.
3The unit repeats the cycle: the output is on for the set percentage of each time base.
4In the inverted function, the cycle starts with the OFF part.
