Remote radio control should also be used in conjunction with a dedicated ‘control unit’.
The following selection of wiring diagrams indicates the wide varietyof possible combina-
tions.
To raise/lower the blind
, by pressing the switch continuously, the speed will change from
the slow speed to the fast speed for raise/lower. Once the fast speed is reached, the but-
ton can be released and the blind will automatically continue to its stop position (top or
bottom). This procedure increase the “life” of the system, since it avoids any excessive
stop/starts. When using a commutator switch, the button will need to be depressed until
the blind reaches the desired position.
To stop the stroke of the blind
, give one impulse to either the UP or DOWN button or
move towards the centre for the double inverter.
Setting of the blind end stops
The motor has a self-learning process: the blind, during the raise and lower operation is
able to recognise the extreme positions and to memorise them. Once these limits are
memorised, the blind will move between these two positions, and when nearing the limit
the blind will slowly come to rest and so avoid sudden stops which results in less stress on
the components.
When the motor experiences a sudden increase in the energy absorption or a remarkable
reduction of the motor speed, as a possible result of glass deflection (e.g. reduced cavity),
the blind will stop. When this occurs all previous limits are over-ridden and the blind will
wait till new one’s are self-learned. When this unexpected stop occurs, and the cause of
the blind to stop is resolved, the original end stop will be automatically reset and the blind
will function normally.
Where it is deemed a faster recognition of the end stop by the motor is required, the fol-
lowing procedure must be followed (at least two times). Raise the blind by pressing the UP
button; the blind raises and forms a stack at the top limit and then goes down a few mil-
limetres, signalling that the end stop has been memorised. Then press the down button
and wait till the blind reaches the lower limit and stops.
Where the blind stops before reaching the lower position, to reset the original end stop
press the down button again until the blind goes down further and then comes to a sud-
den stop. The motor then memorises this lower position and will approach the limit more
slowly when nearing this limit in future movements.
