The above illustration is based on a roller blind application with adjustment of tilting blinds (Reverse Up time
TV of 3 s).
t1: The button for the up-direction is activated. Since the impulse is shorter than the Reverse Up time TV
(3 s), the motor stops when the button is released.
t2: The up-direction is activated again. Since the impulse this time is longer than the Reverse Up time TV, the
roller master control attempts to switch the channel on for the total roll time.
t3: An additional actuation in the same direction stops the motor.
t4: Now the button for the up-direction is activated again and the motor consequently started in the up-
direction.
t5: By activation of the button for the down-direction, the motor is stopped and the Reverse delay TU starts.
t6: After elapse of the Reverse delay TU, the motor rolls in the down-direction.
t7: After elapse of the roll time TL, the motor is stopped. In order to reach the end of the roll time, the
activation of the Down-button must last longer than the Reverse Up time TV.
