Generel information Each FutureVent™-unit has a built in control intelligence with five analogue inputs, one analogue output and one digital output. The units communicate mutually via FutureVent™ bus (FV-Bus) and must therefore be connected to 230V and FutureVent™...
All electrical installations must be done by an authorized company according to national rule and regulation. Cable entries in the unit Cables can be pulled hidden into the unit via insertion holes in the housing. See the mounting instruction (”FutureVent Install WFV_WFB_WFR_WFC_WFD_WFS_WFG_UK_DE_DK_xxxx”) for further details. Cables must be relieved according to applicable rules and would benefit from being stripped near the intake holes.
The length and distance specifications must adhere to the above table. FutureVent™ bus is a ”free topology” meaning it can be connected as a bus, a star or a combination of the two.
Only a few units of the installation are running: With an ohmmeter check the FutureVent™ bus for short circuits. If it is suspected that some of the units are not correctly connected to the FutureVent™ cable, insert a 10k resistor parallel across the bus, and troubleshoot by measuring the resistance on the FutureVent™...
Alle elektriske tilslutninger til anlægget skal udføres af autoriseret firma iht. gældende love og regler. Kabelindføringer i enheden Kabler kan indføres skjult i enheden via indføringshuller i kabinettet. Der henvises til montagevejledningen (”FutureVent Install WFV_WFB_WFR_WFC_WFD_WFS_WFG_UK_DE_DK_xxxx”). Kabler skal aflastes efter gældende regler og kan med fordel af-isoleres tæt på...
Længde og afstandskrav skal overholde afstande angivet i ovenstående tabel. FutureVent™-bus er ”free topology” hvilket betyder, at det kan kobles både som bus og stjerne, eller en kombination heraf.
Kontroller FutureVent™-bussen for kortslutninger med et ohmmeter. Hvis der er mistanke om, at nogle af enhederne ikke er tilsluttet FutureVent™-buskablet korrekt, så monter evt. en 10k modstand parallelt over bussen og fejlfind ved at måle modstanden på FutureVent™-bussen lokalt ved enhederne.
