@HSB-Lee several questions, maybe obvious,

Is the CR sensor fitted the correct way wound? There is a direction arrow on the CT sensor.

Is the CT sensor enabled in VE.Configure?

How is the ET112 set up in the console settings? Is the position setting 'AC Input 1'?

Hi Jason,

Thanks for this information, I have checked both the Inverter position and the CT Sensor is enabled which is shown in my screenshots, CT arrow correct.


Thanks

@HSB-Lee Just a thought, try opening your VRM in a different browser. Another option is to go into the settings, a reboot the GX device.

Hi Jason

I have reset this device many times, Mainly when I make any changes, I have just done so again but as seen in the attached image the problem still exists, do you have any other ideas as to what might be the cause?

Thanks
