769.x Energy: Short circuit voltage too low
Description
Energy monitor
During the series start-up of the monitor, the voltage is measured in short-circuit current. This value must be higher than a lower limit value. If this value is not reached, an error message appears.
Remedy
- Check voltage contacts.
- +800Box: measure unfiltered voltage in the measuring card. This voltage must be > 0.2 volt
- +800 Box: measure the filtered voltage in the measuring card. This voltage must be > 0.2 volt
- Check connector +800:X1.
- Check the digital input.
- Measure the signals of the energy channel.
