USE
The dimmer controller module is to be used with neon lighting equipped with a dimmable electronic starter using a
1-10V control signal, or with a DC-controlled p o we r d immer.
The module is entirely integrated into the Velbus system and controlled through the VMB4PD control panel or
through pushbuttons connected to a VMB8PB pushbutton interface.
To interconnect the Velbus modules it is recommended to use a twisted-pair cable (EIB 2x2x0.8mm2, UTP
8x0.51mm - CAT5 or equivalent).
Make sure to use a he av y - g a u ge wire (0.5mm
2
or more) in case of a multiple module connection (>10 modules) or
with log connections (>50m).
Connect the bus to the module (mind the po larity).
Connection diagram with dimmable neon lighting
The neon lighting must be equipped with a dimmable electronic ballast using a 1-10V control signal.
You can connect several neon tubes to 1 channel.
The Velbuslink program links every dim channel with a relay channel in momentary control so the voltage of the
neon tube drops at 0V in order to switch the lighting completely off.

Connection diagram with power dimmers
In order to dim high-power lamps or a large group of lamps, it is possible to connect one or more DC-controlled
dimmers to the outputs of the dimmer controller.
Note that the 4 channels have 1 common (-) output.

Connection diagram with a RGB LED dimmer
The dimmer controller can also be used to dim RGB LED strips through a DC-controlled RGB LED dimmer. Here,
3 channels are being used.

Termination
Remove the cover.
Terminator
Generally, only 2 ‘TERM’ terminators must be used in a complete Velbus
®
installation. Usually, this will be on one
module inside the distribution box and on the module which is physically located furthest from the distribution box.
On all other modules, the terminator must be removed.
Remark:
In case of a wiring with multiple branches, only place a termination into a single module in the distribution box and
in the control panel which is the farthest from the distribution box. When communication problems occur, you can
place an extra termination on another branch. It is highly recommended to limit the number of terminations as too
large a number may overload the bus.

Configuration
Address, dimmer delay, switch-off delay and control functions can only be configured through the Velbuslink
software.
Address:
Each module in the Velbus connection must have a unique address.
Configure the address through the software.
Dimmer dela y:
If the dimmer module will be used to dim neon lighting, link relay channel in a momentary control to the dimming
channel in order to switch the lamp on or off. As soon as the dimming value i s not 0 (zero), the relay channel will
be activated. To allow the lamp to ignite, you must set a dimming delay during which the lamp’s dimming process
will be briefly stalled.
The dimming delay and relay contact are not necessary when dimming neon lighting.
Switch-off delay:
The neon lighting’s dimming can be linked to a deactivation delay of the relay channel as soon as the dimming
value drops to 0%, this in order to prevent the lamp’s restart when dimming it off and on again.
This featur e is not necessary when dimming neon lighting.
Control functions:
The dimmer module is controlled through pushbuttons connected to the Velbus system via a pushbutton interface
or control panel.
You may assign up to 37 different pushbuttons. Each pushbutton may activate integrate a different function.
