KWh counter 16EC3rn / 1, which means the flashing letter L next to page L1

Question

Hello, I have a question, what does the flashing letter L on the display of the counter 16EC3rn / 1 at phase L1, other phases are ok, nothing blinks only when L1 flashes L. Could this mean a wrong connection of the meter or maybe some damage? I am asking for a quick reply, thank you in advance.

I found the manual for this counter and the problem is probably also Added after 1 [minutes]: I just found the same thing

Additionally, the EC3n meter performs the following functions:
- displaying information about incorrect connection of the meter's current circuits - the L symbol is blinking in the phase with the wrong current direction. It seems to me that only one phase cannot be changed.

Then you would only have to change the phases on coming to the counter. Could such bad phasing of the meter have a negative effect on the meter (higher electricity bill or something similar)?

mar_uda · Answer

It can certainly affect the incorrect counting of the energy used.

1.b · Answer

Only in which way it affects, whether it is beneficial or not for me.

Whether to your disadvantage or not, this should be offset. Someone will see it someday.

The problem is that about 1 year ago this is how the guest who replaced the meter with an electronic one installed it, it was probably some subcontractor for TAURON and now asked what to do next. I called Tauron and they told me that I had to do it on my own and now the question arises why I should pay for something if it is not my fault. Who should be held responsible for it now, because it seems to me that the person who installed the meter.

You spoke to an incompetent person in Tauron. This is how it is on these helplines.
They should respond to such a report. The counter may lower the reading.
However, modern meters are resistant to such an assembly error. They count correctly or save energy in a separate register.

You can do a test - turn off all receivers and turn on one receiver of known power (eg 2kW) per L1 phase. After three minutes, the display should change to 0.1 kWh. Repeat the test on the other phases, because the markings of your phases in the switchgear do not have to be the same as the markings on the meter.

If the reading continues to increase, you have nothing to worry about.

Not true. Replacing only the L1 and L2 supply phase will result in reverse spinning to WLZ, which will result in reversed operation of all 3-phase devices at the recipient, which will involve the need to transfer individual phases on the receivers. To prevent this from happening, you must replace L1 with L2 both in and out.

OK, when I have some time, I'll check it out. So, buddy, you say that there is no point in worrying about it, in total, maybe you are right, since it has been working for 1 year, why should you cover the costs of sealing from your own pocket and not to mention that the electrician also has to earn something if they see themselves, let them find what the counter assumed. Well, with these helplines it's some paranoia, the best thing is when a woman picks up, you explain to her and she does hers anyway.

It is not about the direction of rotation, but the inflow with the outlet changed to L1.
