Hello everyone, I'm installing a Vegadis 82 display and a Vegaplus C21 sensor in an industrial application, both connected to a 4-20 mA loop for level measurement. However, I'm encountering an issue: The Issue: When I connect both the display and the sensor to the 4-20 mA loop, the display doesn't activate. I tested them individually with a 24V external power supply, and they work fine. Background: We had previously used an Endress+Hauser FMU90, but it frequently provided inaccurate readings and isolated between 0 and a specific value. So, we switched to the Vegadis 82 and Vegaplus C21. My Questions: Any ideas on why the Vegadis 82 isn't energizing in the 4-20 mA loop? Are there specific configuration settings or adjustments I need to make for this setup? Is it common for display units or sensors to need an external power supply in a 4-20 mA loop?
