I keep trying to post a request, but something is happened with the web page (this new one), because, in the last step (SEND), the send button is not active.!!!

Thus, please see below my request, if somebody has some answers for me.

Please let me know if you have a detailed drawing, with the wiring for a MMI-3 belt scale, with two junction boxes; the system has :
1. 3 x MSI belt scale => 6 cables (for 6 load cells)
2. 2 x junction boxes (7MH7723-1ND)
3. 1 x BW500
4. 1 x WS300 256ppr
5. the distance between the belt scale (3xMSI) and BW500 = 20m

Otherwise, how should I connect the load cell cables (those six cables) to the BW500, via two junction boxes?

Furthermore, I have some particular questions related to the junction box:
a. which is the scope of the terminals TB5 & TB6?
b. for the terminals TB1/2/3/4 and TB7/8 : why it's important to fulfill the requirements of the input side (from the load cells), respectively integrator side (to the BW500)? there are some electronic components behind the PCB, that force this direction, and not otherwise?

Hello Ivan

Please see the attached connection drawing, I would suggest using two junction boxes if possible.  Connection details are also in the BW500 manual.

Thank you for your answer.

I have this connection drawing, that you have sent it.

But, how should I do the wiring, by using two junction boxes (Milltronics), where I have space only for 4 load cells?

My thought is:

-  to have a parallel connection for the first 4 load cells (from the first and the second MSI, from my system of 3 x MSI = MMI-3), in the first junction box

- the output of this one (first junction box), to be the first pair of cables (from load cells) as input for the second junction box, and the second pair of cables to come from the last (the third) MSI

- the output of this second junction box, to be the pair of cables that goes to BW500 to LCA+/LCA-/LCB+/LCB-

Am I right?

This was the core of my question. I was not sure, if this Milltronics junction box has some restriction regarding the connection of the cables inside - on the PCB, is printed the places where should we connect the input, the output, speed sensor. In the mean time, I have received an answer from Siemens online support, that this PCB has no electronics components. In other words, doesn't matter where we connect the cables, those terminals have just a point to point galvanic connection.
