The above illustration is based on a roller blind application with adjustment of tilting blinds (Reverse Up time
T
V
of 3 s).
t
1
:
The button for the up-direction is activated. Since the impulse is shorter than the Reverse Up time T
V
(3 s), the motor stops when the button is released.
t
2
:
The up-direction is activated again. Since the impulse this time is longer than the Reverse Up time T
V
, the
roller master control attempts to switch the channel on for the total roll time.
t
3
:
An additional actuation in the same direction stops the motor.
t
4
: Now the button for the up-direction is activated again and the motor consequently started in the up-
direction.
t
5
:
By activation of the button for the down-direction, the motor is stopped and the Reverse delay T
U
starts.
t
6
:
After elapse of the Reverse delay T
U
, the motor rolls in the down-direction.
t
7
:
After elapse of the roll time TL, the motor is stopped. In order to reach the end of the roll time, the activa-
tion of the Down-button must last longer than the Reverse Up time T
V
.
