865.x Energy: Measured current too low
Description
Energy monitor
During the series start-up of the monitor, the current is measured via current measuring transformer. This value must be higher than a lower limit value. If this value is not reached, an error message appears.
Remedy
- Check the current measuring transformer.
- +800 Box: measure the unfiltered current at the measuring card (AC signal). This voltage must be > 1.5 volt
- +800 Box: measure the filtered current at the measuring card (AC signal). This voltage must be > 1.5 volt
- Check connector +800:X2.
- Measure the signals of the energy channel.
