PM5000 & PM8000 Demand Register Scaling

[Sepehr_Zarrabi]

In case of PM5563 and also PM8000 does the demand shown on the meter display switch between kW, MW, GW ? If so, what is the boundary at which this switching happens?

Does this affect the numbers that are read through communications?

Is it possible to "lock" the display to only one of kW or MW or GW and not have it scale?

Thank you!

Have you looked at https://www.schneider-electric.com/en/faqs/index?page=content&id=FA203886 for the PM8000. For the PM5563 I am not sure.

Thank you Charles_M for the answer regarding the PM8000 series. Below is how PM55000 series meters work:

The units for Energy values change automatically from Wh to kWh, kWh to MWh, MWh to GWh, GWh to TWh, TWh to PWh, we cannot restrict or limit this change in this meter series.

This is how energy readings on PM5500 display rollover and change units:

1. Values between 0.0000 Wh to 999.99 Wh are displayed in Wh scale
2. Values between 10.000 kWh to 999.99 kWh are displayed in kWh scale
3. Values between 1.0000 MWh to 999.99 MWh are displayed in MWh scale.
4. Values between 1.0000 GWh to 999.99 GWh are displayed in GWh scale
5. Values between 1.0000 TWh to 999.99 TWh are displayed in TWh scale
6. Values between 1.0000 PWh to 9223.3 PWh are displayed in PWh scale

And once value reaches 9223.3 PWh , energy value rollovers and start accumulating again automatically.
