Smartlogger 3000A power adjustment with 4-20mA grid operator signal

Hello, Eoxs.
I checked the user manual of smartlogger 3000A and it shows that only the AI interface supports 4-20mA signal input, but the AI port is used to receive the environmental monitor. And the access signal transmission distance does not exceed 10 meters. I will ask the relevant engineers if there is a way to achieve this.

Thanks.

Hello,

I found the solution.

I'm using a small part of the DRM fuction to reduce the production to zero.

Just need to connect the 4-20mA grid operator signal to AI2 or AI3 or AI4 (AI1 only 0-10v, not 4-20mA!)

Under Settings => DRM, choose the connection port (AI2, AI3 or AI4) and configure the startup current range regarding the signal of your grid operator.

In my case it was 17mA.

If the signal is upper 17mA, production is 100%

If signal is under 17mA, production is reduce to zero !.

The idea now is asking Huawei to have the possiblility to reduce the power smoothly regarding the value of the grid operator.

For exemple:

17mA: production at 75%

14mA: production at 50%

10mA: production at 25%

under 7mA production 0%

Today with the DRM fuction and only 4-20mA signal, we canno't reduce smoothly the production without using DI inputs.
