7.4.- WORKING MODE
Note: This screen is not visible on the “slave” devices.
In this screen, Figure 73, the following parameters of the device's operating mode are configured:
Figure 73: Configuration screen: Operation mode.
● Mode
In this parameter, the control algorithm that the device will use for harmonic filtering is selected, the
options are:
FREQ: Frequency Mode, Harmonic filtering based on the selection of harmonics to be neu-
tralised from 3 to 25.
TEMP: Temporary Mode, Harmonic filtering based on the instantaneous neutralisation of all
harmonics.
Do not use Temporary mode if the supplier has not recommended this for their instal-
lation. This method can cause resonance in certain installations.
● Enabled Functions
In this parameter, you can select the operating mode of the device, i.e., the functions that the device
performs during operation:
Harmonics
Enable this function so that the device performs the filtering of the current harmonics.
Phase balance
Enable this function so that the device performs the current balancing between phases.
