I found this reading with my Metrix:

A: Open limit switch in rest position:

Wire 1 (Green) and 2 (Brown): closed

Wire 3 (White) and 4 (Yellow ): open

B: Open limit switch in Activated position:

Wire 1 (Green) and 2 (Brown): open

Wire 3 (White) and 4 (Yellow ): closed

C: Close limit switch in rest position:

Wire 1 (Green) and 2 (Brown): closed

Wire 3 (White) and 4 (Yellow ): closed

D: Close limit switch in Activated position:

Wire 1 (Green) and 2 (Brown): open

Wire 3 (White) and 4 (Yellow ): closed

As You can see, there is a difference for wire 3 and 4 between the Open and the Close limit switch:

For the Open limit switch, the 3 and 4 wires are changing status from open in rest, to closed when activated

For the Close limit switch, the 3 and 4 wires remains closed in either Rest or activated position

I have no clue about the wiring sequence of course, but since the wires are exactly the same colors, and connected to the same connectors on the limit switch, 

Is this difference normal between the 2 Switches? Or is this indicating a problem on one of the 2 switches ? 

Just to remind you, At the moment:

The shutter motor is working only to close, not to open.

The Close limit switch is stopping the motor when activated, and showing its status on the Dome box screen in rest (not Lit) and activated (Lit). See picture below

.

The Open limit switch does not show any status on the Screen in either rest or activated position

Please let me know

To make the measurements, I disconnected first the connector 12 inside the Shutter box, and made then the Metrix check. So it was not going through the inverter. And I agree as well about the big short circuit ! That's what I mentioned on 21 Jan when I said my differential circuit breaker triggered off-line. I was talking about this short circuit !

I found the wire U connected to the frame of the motor !

And every single V, W and PE connected to U, V and W together (probably through the Rotor windings of the motor, the inverter was disconnected and isolated from the measurements at this moment). This couldn't work, and was necessarily making a short circuit. 

And finally, I disconnected all the wires on the motor side and checked the way of the connection: 

I found (from the inverter to the motor):

U to V

V to W

W to PE

PE to U

Now, I changed the wiring the way You said: 

PE to PE
U to U
V to V
W to W

The situation improved a lot:

First, I connected the PE wire from the Cog Rim to the shutter box, and no short circuit anymore, 👍 .

The motor is turning now (it never did before), when pressing "Close" on the shutter box (and it turns the correct direction). It also stops turning when I activate the LS Close switch. So that's all good.

When I activate the LS close switch (to simulate the shutter Door completely closed), I can also see the indication turning red on the screen (stating "Shutter closed" and the red pointer).

All good 👍 

But I still have one problem left: The motor doesn't turn when I press "Open". I also see that the LS Open is not indicating anything on the screen (like the close switch that turn red when activated)

So I need to see if the LS Open switch is ok (Wiring 32). I checked the wiring from the 32 Pin connector (disconnected) inside the shutter box until the limit switch, that's ok 👍 

So It looks like, either the limit switch has a problem, or the wiring is wrong. i need to investigate on this now. 

It's not easy to follow the wiring colors, since they are not always the same as the ones on the technical drawing of the boxes. So not easy to recognize a possible wiring mistake (Like for the motor). 

Any help, suggestion on this ?

ps. you usually get answers the same or next day. Just check the dates on the forum.

Ok, let me put this way:

U to PE

V to U, V, W

W to U, V, W

PE to U, V, W

Is that more readable?

I paid your plug and pay kit over 3000€ and found a Motor wiring which could have killed me (U to PE amongst other....)

I'm very disappointed the way you treat your customers; I need about 2 days to get answers, sometimes very straight forward answers like: "look on Card Manual page 7.", no more description of the pairing procedure, find out yourself...

And now a complete wrong and dangerous wiring, and a simple "unreadable diagram" as an answer? I spent 4 hours to make this troubleshoot and the drawing..

I believe my drawing is very clear, but find your service and after sale very poor.

I will proceed with the change of the Wiring, and hope it's gonna work now.

When connecting the PE wire coming from the Cog Rim, My Differential circuit breaker is triggered. 

If I disconnect the PE wire from the Cog Rim, it works, and I have power to the shutter motor, and the 3 power outlets. 

So the PE wire is creating a short circuit. 

Since I cannot get the shutter motor to work, I suspected a problem on that motor.

I opened the junction box of the motor. There are 4 wires. I checked the black wire, which is screwed onto the metallic Motor frame, with the PE wire from the Cog Rim, and was surprised to find this wire not connected.

I opened the shutter box and checked the wires from the connector 12 (the one going to the motor). 

Here is a drawing of what I found (see attached pdf)

As you can see, the red wire, connected to the U of the Inverter, is connected to the Metallic Motor frame. (Black wire on the picture screwed onto the Motor frame)

The Ground Wire from the Inverter is connected to U, V and W on the Motor Connection box.

It cannot be to have a ground wire connected to the 3 Phase (U, V and W) ?  

And it cannot be to have U connected to the Motor metallic frame? 

Please let me know.

The "Slave" 230v is not ticked. Is that telling me I have no AC delivered to the motor?
