Selectivity/Discrimination

[Unknown]

I've been looking at the selectivity tables in the program and I've found that I'm not getting warnings when I don't achieve full selectivity.

Is there an option somewhere I need to enable for this to happen?

There are various reasons, and one of them is hiding selectivity warnings. Check the buttons above the selectivity area and make sure selectivity is not hidden.

Hi Mert

thanks for the reply.

I've had a look above the selectivity area as you have suggested and I can't find any buttons that might hide selectivity.

I've also looked at the calculation options under "Project info and options" but couldn't see anything relating to hiding selectivity.

Would you be able to provide screenshots of where these buttons are?

thanks.

Hi

thanks for the reply.

I've had a play around with the options shown in the screenshots but I still can't get the software to warn me when I'm not achieving full selectivity.

Can you show me an example of the software warning that total selectivity is not achieved?

Hi

Thanks for posting that image. That helps a lot.

Although that now leads me onto a further question. Below is an example of where I'm not achieving full selectivity:




On this calculations, it states that selectivity tables are not available, please consult with the manufacturers data.

When I use Schneiders online selectivity tool, I end up with the same limit for selectivity given in the table with ElecOM. So I'm a bit confused as it looks like the information is available within ElecOM, or have I misunderstood the message?

Hi,

That message must be related to another circuit. Please email us at support@modecsoft.com and attach your eom file; we will provide more details.

Many thanks
