Remote radio control should also be used in conjunction with a dedicated “control unit”.
The following selection of wiring diagrams indicates the wide variety of possible combina-
tions.
To raise/lower the blind
, press the Up or Down switch until the speed increases. Once
the fast speed is reached the button can be released and the blind will continue to move,
reaching the end stop where it automatically slows. This method of operation increases the
life of the system, since it avoids any involuntary interventions. For systems without the
control unit press the switch till the desired position is reached.
To stop the stroke of the blind
, press the Up or Down button or move towards the cen-
tre the double commutator switch.
Setting of the blind end stops
The setting of the blind end stops is carried out in the Company during manufacture.
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.
