Frequently Asked Questions - VMBSTART-B-10 Velbus

What is the purpose of the VMBSTART-B-10?

The VMBSTART-B-10 is a bus start module used in Velbus home automation systems. It initializes and terminates the Velbus backbone, ensuring proper communication between devices.

How do I install the VMBSTART-B-10?

Mount the module on a DIN rail inside the distribution board. Connect the bus wires to the 4-pin screw terminal (V+, V-, D+, D-). Ensure the bus is powered before connecting.

What do the LED indicators mean?

A green LED indicates normal bus operation. A red LED signals a bus error, such as short circuit or incorrect wiring.

Can I use multiple VMBSTART-B-10 modules in one system?

No, only one bus start module is allowed per Velbus backbone. Using multiple can cause bus conflicts.

What power supply does it require?

The module is powered directly from the Velbus 24 V DC bus. It does not need an external power source.

Is the VMBSTART-B-10 compatible with older Velbus devices?

Yes, it is backward compatible with all Velbus modules using the standard Velbus protocol.

What are the dimensions of the VMBSTART-B-10?

It occupies 3 DIN modules (approx. 53 mm width) and fits standard distribution boards.

How do I troubleshoot if the red LED stays on?

Check the bus wiring for short circuits or reversed polarity. Ensure the bus voltage is between 20-30 V DC. If persists, replace the module.

Does the VMBSTART-B-10 require any configuration?

No, it is plug-and-play. It automatically detects the bus and initializes communication.

Where can I download the manual?

The manual is available for free download in PDF format from the manufacturer's website or notice-facile.com.

Important notes:

• You can add multiple Velbus DIN rail modules between the VMBUSB and VMB4RYNO modules.
• Use the included Molex cable to connect the VMB4RYNO module to the VMBPSU module. Cut off one side of the Molex connector, strip the black (-) and red (+) wires, and connect them to the VMBPSU.
• The Molex connections on the VMB4RYNO and VMBUSB modules are internally connected. It does not matter which port you use.
• Each DIN rail module comes with a Molex cable for daisy-chaining the bus. Need additional (longer) cables? See our VMBCABLE20SET, VMBCABLE40SET and VMBCABLE150SET.
• Strip both ends of the EIB cable and connect them to the connectors on the VMBELO and VMBUSB modules. Follow the color coding of the bus connections:

Step 2: Configuring the Terminators

All Velbus modules (except the VMBUSB-20) are equipped with a terminator (a switch marked "TERM") that is open by default. In every Velbus installation, at least two terminators must be closed, with as much cable distance as possible between them. These are usually the first and last (farthest) modules in the installation.

For DIN rail modules, open the front panel to access the terminator. For other modules, the terminator is located on the back. The terminator is enabled when the corresponding LED is lit.

In this basic setup, close the terminator on both the VMBELO panel and the VMB4RYNO module.

Step 3: Checking the BUS Connection

Velbus is a highly stable system, but any issues are usually caused by poor BUS connections. Always perform the following check during the initial installation and after any cabling changes:

Press any button on a module (except the RESET button). You will see the LED next to the TX (transmit) marking light up briefly. At the same time, the RX (receive) LEDs on all other modules in your installation will also briefly light up. This indicates that a signal from the module is correctly placed on the bus and received by the other modules.

Repeat this test for all other modules in your installation (except for the VMBUSB module, as it has no buttons). If the other modules do not respond to the signal, double-check the cabling and follow our troubleshooting guide.

Step 4: Programming via PC

- Download the latest Velbuslink software from www.velbus.eu/downloads. The installation does not require admin rights unless you want to install the optional USB drivers.

- Connect the VMBUSB module to your computer using the included USB cable after installing Velbuslink, and start the program.

- Click on "New" (top left) to start the "Create a new project" wizard. Select Next for the following options: "Connect to an existing installation" and "Direct connection via cable".

During the scanning of the installation, you may allow automatic address assignment.

Do not do this if you are reading an existing (functioning) installation.

Select how modules are added to your project:

Scan my installation for modules

√ Auto-assign addresses

○ Start with an empty project and add modules later

For a new project (as with this starter kit), you can choose to start with empty modules in this screen. For an existing (functioning) installation, first read all the settings. Depending on the size of the installation, this may take some time.

Select whether or not the module memories are retrieved:

○ Read settings from my existing installation (recommended) (Modules with an invalid address will not be read)

Start with blank modules

Once the reading process is complete, a confirmation message will appear, and you can start configuring.

Press Finish to start configuring your installation.

- In the navigation panel, you will now see both the VMBELO and VMB4RYNO modules. You can expand the channels of a module by clicking on the "+" symbol next to their names.

- Left-click on the name of the selected module or channel to rename it. For example, change "Relay 1" to "Kitchen Light".

- Drag "Button 1" from the VMBELO module to the VMB4RYNO module and drop it on Relay 1 ("Kitchen Light"). In the dialog box, select the action "Toggle" and press OK.

- Press the "Synchronize" button.

In the "Project Synchronization" window, check "Only changes" and press "Write".

When the writing process is complete (this should only take a few seconds), you can now control Relay 1 ("Kitchen Light") by pressing the left button (Button 1) on the glass control panel.

- To modify the text on the OLED screen, select the VMBELO module in Velbuslink and click on the gear icon (or press F6).

- In the configuration window, click the button "Create a new image" and add names and icons.

Do not forget to synchronize (save changes to the modules) before testing the changes you made.

Additional Information

On the website www.velbus.eu/downloads, you can find three important documents in the installation guide section: the Hardware Installation Guide, the Software Configuration Guide, and the Troubleshooting Guide. We recommend reading these documents carefully to fully explore the capabilities of Velbus.

Troubleshooting

If the system is not functioning correctly, carefully check the wiring, ensure the terminators are configured properly and restart the installation (briefly interrupt the power supply).

If the problem persists, visit the support pages at www.velbus.eu or contact your Velbus distributor. Technical support is available via the Velbus ticket system: help.velbus.eu.

Warnings

Velbus products are intended for installation by a professional installer:

• All work must be performed on a de-energized installation.
  • The installation must comply with the applicable regulations of your country.
• Follow proper workmanship practices.

If in doubt, contact your wholesaler.
