Siwarex M module: Which voltage (=VDC) do you measure?

Hello Siwarexi,

I've posted on the similar issue in another topic:

1. EXC:

between the pins 19(+) and 20(-) at the Siwarex M module:

Which voltage (=VDC) do you measure? 10.2VDC

2. SEN:

between the pins 15(+) and 16(-) at the Siwarex M module:

Which voltage (=VDC) do you measure? 10.1VDC

3. SIG:

between the pins 17(+) and 18(-) at the Siwarex M module.: 1.85VDC

 Dear Team,

Waiting for your response. The matter is related to breakdown of equipment.

Kindly co-operate!

Dear Team,

Please provide the respond that what to do of the Siwarex Module. Already I've mentioned that the  & Voltage measured in the terminals 17 & 18 are 1.8mVDC respectively. If the Load needs to be calibrated properly then what should the rated voltage at those terminals should come?

Also it's to mention that SF led is continuously LED in the module & when getting Online with Siwatool the Hardware Fault indication is showing.

Hence kindly guide me how to finalize the issue!

Hello Siwarexi

Thank you very much for the information. I will check and let you know

Hello Siwarexi,

We have selected the load cell signal on 4nv/VDC & here are the following values which we have gained:

Load Cell 01-

Unloaded: 1.1mV

Ext. Voltage: 10.2VDC

20kg Load: 4.9mVDC

Load Cell 02-

Unloaded: 1.9mV

Ext. Voltage: 10.2VDC

20kg Load: 8.1mVDC

 Load Cell 03-

Unloaded: 2.6mV

Ext. Voltage: 10.2VDC

20kg Load: 11.8mVDC

Now my queries are that why such variations are coming for the 20kg Load issues. We have got that Load Cell 01 is damaged but then what could be the possible reasons for Load Cell 02 & 03 data variations? If we have to minimize these voltage fluctuations how will it be possible to overcome with! There are 03 nos of Load cells installed in the field on a conveyor type weighing scale & the pattern of installation is in triangular pattern.

The MLFB of the Load cell's is: 7MH5106-2GD00, maximum Load capacity is 20kg. Kindly refer the attachment for requisites collected Data from field.

Waiting for your response.

Hi Siwarexi,

Yes I have individually loaded each load cell with 20kg load and have provided the results in previous post.
