DESCRIPTION The module features four 0/1 to 10V outputs. Each output can accept one or more DC-controlled power dimmers so as to dim large groups of bulbs simultaneously. The module also allows you to dim neon lighting equipped with a dimmable electronic starter with 1-10V control input. Controlling DC-controlled LED dimmers allows also an attractive ambient lighting. Each channel can memorize several dimming functions and preset ambiances.

LOCAL CONTROL Remove the cover.
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 power dimmer. 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).
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.
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 delay: 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 is not 0 (zero), the relay channel will be activated.
14 Toggle with timers disabled at short press Each press toggles the lighting status (on/off). The timers cannot be started when the lighting was switched on by a short press. 15 Toggle with timers disabled at long press Each press toggles the lighting status (on/off). The timers cannot be started when the lighting was switched on by a long press. 16 Slow toggle Each press switches the lighting slowly on or off.
30 Toggle at short press Dimming at long press A short press of the pushbutton switches the switched-off lighting fully on or switches the switched-on lighting fully off. A long press of the pushbutton dims the lighting up or down. The intensity is maintained at release of the pushbutton. The lighting switches off after the switch-off delay has expired.
45 Inhibition at closed switch The lighting is switched off as long as the switch is closed. The functions continue to operate internally. The internal status is transferred to the lighting as soon as the switch is opened. 46 Inhibition at open switch The lighting is switched off as long as the switch is open. The functions continue to operate internally. The internal status is transferred to the lighting as soon as the switch is closed.
CHECKING THE SOFTWARE VERSION The software version can be verified via the Velbus link software. Check on http://www.velbus.eu whether you have the latest version. If a newer version is available, download it. Connect the Velbus interface to a PC and run the upgrade-software and follow the instructions on the screen. Remark: Upgrading a module is not without risk. Do not interrupt the process! If for any reason the upgrade should fail, the module will cease normal operation.
