We have a case with PQ and LT where negative energy has to be measured (export energy) but on both meters energy is measured as absolute. Only import energy is measured.

To avoid wrong wiring – the LT & PQ have automatic mode to swap the current line when it feels negative power.

In this auto mode – you can’t read import/export.

You should set the mode to ‘FIX’.

To set this goto Technical menu -> Wirring -> Current Lines and set it to FIX.

 

To do so in PQ goto Technical menu and when asked for password

Enter code 201 – for auto mode

Enter code 202 – for fix mode

Now – when the system is in FIX mode – double check the L&K current wiring – as the Elnet don’t swap it to correct wrong wiring..

In FIX mode the Elnet works correctly with Import / Export energy.

 

To check correct wiring you can also enter code 11 when asked for password.
