E2. Why use a relay box RI2?
Sun blinds consisting of 3 or 4 panels are always driven by 2 motors. These motors can be operated
each using a separate switch. This allows the panels to be opened separately in pairs. However, if you
want to operate the sun blind by using a single switch, it is necessary to use a relay box. If this is not
done, the system will oscillate, and the high inductive and capacitative voltages created will perma-
nently burn out the built-in switches in the motor housing. Therefore this good advice : always use
the relay box and switches we supply for single operation of 2 or more motors. The same applies to a
“wind/sun automat”.
