How it works

1When the start input closes (or on power-up if it is already closed) T1 starts and the TIMER 1 output switches on.
2At the end of T1 its output switches off and the pause starts.
3At the end of the pause the TIMER 2 output switches on for T2; then another pause follows and the cycle repeats.
4Without memory, after a power cut the cycle starts from zero; with memory, it continues where it was.

Frequently asked questions

What is the pause for?

When reversing direction, it lets the motor stop by inertia before starting in the opposite direction.

Are the three times programmed separately?

Yes: T1, T2 and the pause are programmed from the keypad, each with its own range.

What happens after a power cut?

Without memory the cycle starts again from zero; with memory it continues where it was.
