When the motor is switched off by a limit switch, the corresponding contact on the blind/shutter actuator
remains closed until the parametrized total travel time has elapsed, including any programmed "overrun"
time. A voltage remains applied to the output up until this point.
Note
Total travel time also determines the current position of the blind in ongoing operation. Therefore it
should be measured and parametrized as accurately as possible, particularly if the functions
Move to
position
or
Automatic control
are used. This is the only way to accurately calculate the blind position.
Slat adjustment switch on duration
After the blind moves upwards, the slats are open (horizontal slat position). When the blind is lowered,
the slats are initially closed (vertical slat position) and the blind moves downwards. If the blind is now
raised again, the slats will be re-opened (horizontal slat position) and will then be moved upwards.
To adjust the slat angle more precisely, the Blind/Roller Shutter Actuator can be used to execute short
movements. These move the blind for a brief parametrized time – the so-called
Slat adjustment switch on
duration
– in the required direction, thus adjusting the slats (STEP telegram). The shorter this duration, the
more accurately the slat angle can be adjusted.
