CONNECTION
For connection between the modules, use twisted pair cable (ex. EIB 2x2x0.8mm2, UTP 8x0.51mm - CAT5 or
other). Use minimum 0.5mm² cable. For long wiring (>50m) or if a lot of modules ( > 10) are connected to one
wire, use 1mm² cable. Connect the 12-18Vdc (mind the polarity) and connect the bus wires (mind the polarity).
Connect the roll-down shutter motor according to the drawing below.
The roll-down shutter can be controlled through push buttons which are directly connected to the push button
inputs by using the VELBUS or a combination of both.
Direct control through several push buttons :

Remark:
To cut the communication with the VELBUS system, enter the address as ‘00’ so as not to report modifications
in the status. Clear all learned push buttons (see learning mode) so as not to send any instructions over the
VELBUS to control the indication LEDs of the push buttons.
If this is not the case, the blind control module will create a bus error with each status modification.
