Description of the display window
9.9 Extras window:
Extras
next 
Press
W
to select submenus.
The additional possible settings are displayed in the submenus of this window,:
If a submenu is selected (by pressing
W
), the settings can be changed by pressing
U
to
start entering values,
V
to change the setting and
X
to save it.
The following submenus are available:
 User language:
In this submenu, you can select the language for the LCD display (German, English,
French or Spanish).
 Limit THD:
The harmonic switch-off limit refers to the total of all measuring voltage harmonics (Lim
THD). The programming range is between 0 and 10%. The setting can be adjusted in
increments of 1 %.
In addition, harmonics monitoring can also be disabled here (limit monitoring is deacti-
vated if the setting is Lim = 0%).
If voltage harmonics exceed the limit, an error message is displayed and a stage switch-
off is performed.
 Operating cycle limit:
The limit of the capacitor contactor operating cycles is used as an indication to cus-
tomers that the capacitor contactor could be worn out due to the number of switching
operations accumulated. This message in no way influences the function of the com-
pensation system. It is merely used as a "maintenance instruction".
However, the operating cycles of the thyristor stages are not taken into consider-
ation for this.
If the setting is Lim = 0%, limit monitoring is deactivated but the operating cycle count
is still activated.
 Sampling rate:
The power frequency tracing settings are displayed in this submenu. The setting "Auto"
causes the sampling rate to be traced automatically, within a range of 40 to 70 Hertz.
Alternatively, a fixed sampling rate of
50 Hz or 60 Hz can be set.
