If the cogeneration mode is enabled (Cogeneration = ON), by setting this parameter to “ON” the CT direction can be
reversed via software without acting on the connections.
After parameter is confirmed, the controller will move to the next parameter setting screen (Cogeneration).
7.1.5 Cogeneration
The default value is "OFF". The possible permitted values for the parameter are [ON; OFF].
Set parameter to “ON” when the CT is mounted on a line on which the current is generated by cogeneration systems
and is absorbed by the load. If this parameter is set to “OFF” the CT direction will be automatically corrected via software
to achieve always positive active power values.
After parameter is confirmed, the controller will move to the next parameter setting screen (Frequency).
7.1.6 Frequency
The default value is "Aut". The possible permitted values for the parameter are [50; 60; Aut].
Set the “Aut” value to enable the automatic selection between 50 and 60Hz upon controller first powering-up. In case
of an excessive voltage harmonic distortion (measurement THDV%), we recommend setting the value at 50 Hz or 60 Hz,
based on system nominal frequency.
After parameter is confirmed, the controller will move to the next parameter setting screen (VT primary winding).
7.1.7 VT primary winding
The default value is "400". The permitted range for the parameter is [210÷160000].
Example 1: if the transformer size is 690/400, enter the "690" value. NOTE: if the VT is not present, set the supply
voltage value used for the Power Factor Controller (400 or 230).
Example 2: if the used VT Primary winding is equal to 100000A, set:
If a permitted value is entered, the controller will move to the next parameter setting screen (VT secondary
winding).
