Features:
◊ Can be used to control an electric roll-down shutter, sunblind...
◊ Switching capacity at resistive load: 16A/230VAC max.
◊ Switching capacity at inductive load: 8A/230VAC max.
◊ Suppressed relay contacts.
◊ Manual control on the module.
◊ LED indications for:
• The UP and DOWN relay output
• The UP and DOWN control modes (fast, very fast or blinking twice and continuously ON)
• Power voltage
• Data reception and forwarding through VELBUS
◊ 4 possible switching times (adjustable through the ‘TIME OUT’ toggle switch): 15s - 30s - 1min - 2 min
◊ Controllable by connecting several push buttons in parallel.
◊ Push button input debounce: 65ms.
◊ Controllable trough VELBUS.
◊ Programmable without PC.
◊ Easy learning process by pressing the desired push buttons in the learning mode.
◊ Push button commands: up, down, immediately up and immediately down (the up and down commands will
be operated through a single push button as from firmware version 0804).
◊ Storage space for 14 different push buttons per command group (11 per command group as from firmware
version 0804).
◊ Learned push buttons will be saved in case of power failure.
◊ Reporting towards the control modules in case of LED status modification.
◊ 250 possible addresses (adjustable through the ‘ADDR’ rotating switches)
◊ Required mains voltage: 12 ... 18VDC.
◊ Consumption in standby: 30mA at 18V (15mA at 16V)
◊ Consumption activated relay: 80mA at 18V (60mA at 16VDC)
◊ Max. consumption (activated relay and push button input): 95mA at 18V (75mA at 16VDC)
◊ Standard DIN rail housing (2 modules)
◊ Dimensions (L x W x H): 90 x 36 x 58mm.
◊ Weight: 110g
VELBUS:
2-wire communication for the VELBUS data and 2 wires for power.
Data transfer: 16,6Kbit/s.
Serial data protocol: CAN (Controller Area Network)
Short-circuit proof (towards negative or positive of power)
Bus error indication: 2 x short flash of the operation mode LED.
Self restoring after 25 seconds in case of a bus error.
Possibility to assign a name (max. 16 characters) to the UP and DOWN output which can be saved in the nonvolatile memory.
The module can react to the push button instructions sent over the VELBUS.
Reporting on the VELBUS in case of a modification of the blind control module.
In case of a modification of the output, the module will send instructions to modify the status of the LEDs on
the control modules.
The instructions will be accepted when calling up the module type, the output names, the module status,
reading from or writing on the non-volatile memory, the rising, the descending and the stopping of the shutter.
The module can respond with the module type, the output names, the module status or the contents from the
memory.

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.

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.
