Velleman VMB8PBU - Manual (Page 10)

10 8-channel pushbutton module | VMB8PBU – ed.1
TERMINATOR
In normal circumstances only 2 ‘TERM’ terminators must be foreseen in a complete Velbus installation. Usually this
will be on one module inside the distribution box and on the module the furthest from the distribution box.
In all other cases it must be removed.
USE
The pushbutton interface module is added to the Velbus system.
To all eight pushbuttons actions can be attributed to control relay channels e.g. switch them on or off, dim lights, open
or close window shutters and so on …
Configuration can only be done through the Velbuslink software.
Address:
Every module in the Velbus system must have a unique address.
Address setting is done by software.
Name:
Each button can be assigned a name (max. 16 characters) via the Velbuslink software. This can be very handy during
configuration of actions (controlling a relay, dimmer, window shutter…)
Response time:
Determines how long the pushbutton must be pushed for the action to take place. This can be immediately or after 1, 2
or 3 seconds.
Tip: For a pushbutton with action ‘All off’ it is better to configure a response time of 3 seconds.
Suppressing:
Unused pushbuttons may be suppressed.
Tip: To avoid accidental operation of the awing during wintertime, suppress those pushbuttons in winter and only make
them available during summertime.
Inversion:
It is possible to make a pushbutton act as being normally closed.
Backlighting:
The indication LED on the pushbutton may glow softly to locate the pushbutton in the dark. The brightness of the
backlighting can be adjusted. When desired, backlighting can be switched off completely.
Feedback:
The indication LED on the pushbutton can indicate the status of the action it controls. It can be on or off or when a
timer is running flash slowly or fast. If the flashing is disturbing, it can be changed to continuously on. It is also possible
to disable feedback.
Remark:
In a wiring scheme with a lot of branches a
terminator is placed on a module inside the
distribution box and on the control panel
furthest from the distribution box. Should
communication problems occur, an additional
terminator can be placed on another branch.
However, the number of terminators should
be kept to a minimum as additional
terminators place a heavy load on the bus.
