2/2008 Appendix C—EN50160 Evaluation
EN–239
Setting Up EN50160 Evaluation from the Display
To set up the EN50160 evaluation in the meter, you need to perform
these steps:
1. Enable the EN50160 evaluation.
By default, the EN50160 evaluation is disabled. To enable the
evaluation, use the display (see “Set Up the EN50160 Evaluation”
on page 30).
2. Select the nominal voltage of your system.
The EN50160 standard defines nominal voltage for low-voltage
systems to be 230V line-to-line for 3-wire systems or 230V
line-to-neutral for 4-wire systems. Therefore, the default value for
Nominal Voltage is 230. If the application is a medium-voltage
system or if you want the evaluations to be based on some other
nominal voltage, you can configure this value using the display
only. WinPM.Net does not allow configuration of nominal voltage.
3. Change the nominal frequency of your system if you are
evaluating a 50 Hz system.
The EN50160 standard defines nominal frequency as 50 Hz, but
the ACCESS 9360 can also evaluate 60 Hz systems. It cannot
evaluate nominal frequency for 400 Hz systems. The default
nominal frequency in the ACCESS 9360 is 60 Hz. To change the
default, from the display Main Menu, select Setup > Meter >
Frequency. From WinPM.Net software, see the online help file.
4. Reset the EN50160 Statistics.
a. Write 9999 in register 8001.
b. Write 11100 in register 8000.
Refer to “Resetting Statistics” on page 228.
