5501RBCP with window actuator

Hi All,
I have some window actuators (https://www.assaabloy.com/nz/en/sol...w-products/window-winders/interlock-elevation) , they are existing, they have these silly interface boxes called "interlock elevation" (wiring as per pic below) i want to bring them into cbus with a shutter relay, i was hoping for a single common, but no such luck,

At this stage from a brief read of the manual i am thinking that i apply no power at all to the shutter relay and can chuck one com in the A/L slot then Green/brown in the open and close of the shutter relay. but this wont account for the opto isolated Com cables (blue white)

on paper it seems like it would partially work, but thought id ask if any one has any other ideas or has done something similar before i carry on.

The other thing to try is to tie the 2 COM cables (blue and white ) together and see if it functions, although it seems weird that they would supply opto isolated pairs if they were not required.

i guess i could do it with 2 shurtter relay per window actuator one for open and one for close with the same GA in each?
although not sure how this would go as an interlock?

am i re-inventing the wheel and there is a super simple way i have overlooked??

 

Have you tried measuring any continuity between cables, or if any voltages come out? It's unlikely to be opto isolated as you would need an isolated dc supply on the switch side.
it's also worth checking if there is an ac voltage on the switch inputs as a common isolation technique is to use a transformer on the input, place an ac waveform on the primary (inside) windings then check for an increase in primary current that will occur when the output leads are shorted.

 

I unfortunately have a job at the moment using these window actuators and they are painful. I have tried to use both common cables (Blue and White) in the same terminal and the system doesn't seem to like it and dose not operate correctly, you may be able to get this to work but I was not able to.

However this system dose not operate like a traditional blind motor. To actuate the blind all you need to do is push the respective button for 2 sec and the blind will Open/Close all the way. You should be able to use C-Bus ELV relay and a switch set to bell press to achieve this.

 

If you are looking for a cheap option, I'm using Tuya smart wifi switches (or equivalent) reflashed with Tasmota firmware. Then you can use simple http commands from the SHAC to control them.

 

Hmmm.
Yeah, so I had a poke round with my multimeter looks like there is 2v dc between all +ve and -ve
Gn -
Br +
Blu -
wh +

also one common is + trigger and one common is - trigger, which explains why connecting them together dosnt work…

think im gona just use 2 relay chan per blind and do 2 buttons - up and down.
Although it would be nicer to have one button and have it work like a shutter relay I don’t think it’s worth the bother.

 

DO NOT put any power on the Blind relay - the small interface box is for dry contact only - the interface box is like looking for a push button as per picture,
Try white and blue together in the A/L of shutter relay and then put green in close of the shutter relay and the brown to open of the shutter relay as you thought. the shutter realy switches from the C-bus power, you can time the window to set the disconnect time and default you should get O-S-C function straight out of the box, and if using proportional and time set right probably can do % openings as well? just a thought if you have the materials already I have used something similiar from ASSAABLOY but under a different name it was called a network controller?
