Bubendorff blind motor MG and consumption

Hi everybody,

I use VMB2BL to control my 11 blinds. As it is Bubendorff MG motor, there is 4 wires :

  • Permanent Phase
  • Neutral
  • UP
  • DOWN

however, these motors could receive CPL signals and it seems that it cost power (around 18W when sleeping / doing nothing) : that way, my house use around 200W for nothing :open_mouth:

Have anybody the same problem ? is it possible to put permanent phase on a VMB4RY (what is the power consumption when blind become active) ?

Any experience is waited :unamused:

finalement q’est ce que tu as pu faire? comme il nya pas de réponse, je prendrai des moteurs à 3 fils!!!

Pour le moment, pas de réponse… et avant d’acheter les VMB4RY nécessaires, je dois connaître la consommation crête de ces fichus moteurs car limitation à 300W par Velbus sur les relais !

VMB4Ry??

Tu veux dire VMb2bl, je crois.

300W?? c’est sur

Charge INDUCTIVE:8 A 230v d’apres doc vmb2bl

P = UI cos(f)

donc pour le moteur p<UI = 1840 W

corrige moi si je me trompe, pas sur.

Non, le VMB2BL controle la montée et la descente.
Le VMB4RY serait pour couper le 230v permanent mais… je ne sais pas s’il passe de la puissance dedans ou non :unamused:
Il me faut un relais par disjoncteur (les 11 volets n’étant pas tous derrière le même disjoncteur 20A).

The standby current of the VMB2BL is 35mA @ 15V and the current when the two channels are activated is 130mA @ 15V

Hi VEL324 (a first name would be more friendly but…)

I need the consumption of Bubendorff motor in sleep mode and active mode, however, not for the same Velbus module :

  1. VMB2BL controls UP/Down wire → active mode
  2. VMB4RY would controls sleep mode (around 18W for what I can imagine…) and maybe an other consumption on permanent phase wire (Bubendorff MG motors have 4 wires : UP, Down, Neutral and permanent phase)

So in this case, Velbus is OK but Bubendorff don’t answer to my question : what is the cunsumption on the permanent phase (sleep and active mode).

I take little time to make this draw… Velbus, please me if you can contact Bubendorff directly (maybe your society could have more power than a simple user) because it use 200W permanently !!!
Idea is to start VMB4RY in same time that VMB2BL but keep VMB4RY active for a timer of 5mn (for example).

Golfy,

Have you tried measuring the current yourself, seems to be the fastest way to know the power used.
Have you tried running the motors without the permanent phase?
You could use two 2NO relais per blind (like the vynckier CTX+R1620230A for example) and switch the up/down and the permanent phase (about 25€ a pop, so will be over 550€ for you complete installation)

Not easy to do because directly connected on disjoncteur : maybe put the multimeter in (10A mode)

Of course : nothing happens :frowning:

I used Schneider Electric parts (Ah yes, Grenoble is the born place of Merlin-Gerin wich become Schneider Electric :wink: ) relais for controlled electrical plug… but want to avoid 550€ if not needed :laughing:

can’t you ude the vmb4ry in momentairy mode and than be activated by a blind up/down command. I thought a relais module could control another module (commando side seen) instead of using an input switch module.

Golfy,

Measuring the current would be easy with a clamp meter if you have one available.

You could use a vmb4ry(ld/no) channel per blind and add the relais command to your up/down buttons (make sure to use a timer), but you’ll need 3 modules at €179 a pop wich will cost you €537. So it wouldn’t be much cheaper. Plus, the vmb4ry draws a standby current (not much but a relais doesn’t)

Have you tried contacting the manufacturer of your motors? Maybe they have a solution?

A simple Google search revealed this:
forumconstruire.com/construire/topic-129891.php
Maybe it helps.

I presume the “Golfy” on that forum is the same as the one we have here?
:wink:

Did not look at the second page… :slight_smile:

Yes it’s me in each case (the day I works as a nice employee for a respectable society… but the night, I’ve others suspicious activities… but my name isn’t Neo or Anderson :wink: )

ouf I’ve not write anything bad on Velbus in others forums :laughing:

So I think this week-end would be a test week : Bubendorff seems to be deaf :imp:

Hello guys,

Bubendorff still deaf to my requests but my multimeter is my best friend (after Google search of course) :wink:

So I used the intensity mode (10A) and insert the multimeter between 230V and my bigger blind (2,80 x 2,10 meter).
Bubendorff MG Motor consumption :
Standby mode : 120mA (~27,6 VA)
Active mode : 840mA (~193,2 VA)

Hope this will help some guys 8)
Of course, no thanks to Bubendorff France (maybe they’re better in other countries) :angry:

BRAVO!

that’s why, I will buy a noname motor, with 3 wires, with velbus you do not need some motors with useless extra futures.

specially that my biggest blinds will be 3mX2.6, I had to split 6M into 1.5+1.5+3, to avoid problems.

Viva velbus!
