... The On and Off delays are adjusted by 2 different potentiometers. Energisation of the relay causes the output contact to close instantaneously and start the timing period. The contact returns to its initial position when the set time delay (t) has elapsed or if the supply is cut off before the end of the timing period. ...

... External control of starting: opening of an external contact connected to the relay starts the timing period. Closing of this contact resets the timer. External control of partial stop of time delay: closing of an external contact connected to the relay allows the timing period to be interrupted. The time elapsed is memorised ...
