VELBUS:
2-wire communication for 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) and a reaction time (65ms, 1s, 2s of 3s) which can be saved
in the non-volatile memory.
The module can react to push button messages sent over the VELBUS.
A modification of the dim status will be reported on the VELBUS.
When modifying the dim status, the module will send instructions to adjust the status of the LEDs on the
control modules.
Instructions will be accepted when calling up the module type, module name, module status, reading from or
writing to the non-volatile memory, configuration of the light intensity and when starting or stopping the timer.
The module can respond with the module type, module name, module status or the contents from the memory.

Opgelet:
•Place the ‘MODE’ rotary switch on one of the following positions: : 8, 9, A, B, C, D, E or F.
•The electronic transformer must be short-circuit and thermal protected.
•Make sure to always connect a lamp on the transformer (an unloaded transformer has an inductive behavior
and could damage the dimmer).
•This dimmer is not suited for toroidal transformers.
Troubleshooting:
The dimmer module features a non-resettable fuse which will melt in case of a short-circuit or overload. In this
case, return the dimmer to the manufacturer for repair. If the lamp does not go out due to an external cause (even
after switching off and on the mains), the control transistor will probably be faulty. In this case, return the dimmer
to the manufacturer for repair.

Connect the 12 to 18VCC (mind the polarity) to the module. Make sure to use a heavier wire gauge (0,5mm2 or
more) with long connections. The dimmer module can be controlled via push buttons which are directly connected
to the push button input by using the VELBUS or a combination of both possibilities.

Remove the lid from the dimmer module using a small screwdriver and modify the configuration.
Replace the lid
Termination:
If the module is connected at the start or end of a cable on the VELBUS, place the ‘TERM’ jumper.
Remove the jumper in all other cases.
Remark: If different cable wiring topologies (tree, star, loop, ...) are used, place a jumper on the end module of
the longest cable only, NOT on each end point
