.
In the submenus of this window, the settings made for the switching performance by default are displayed
(default settings). These settings apply to most of the compensation facilities.
The following submenus are available to influence the switching performance.
Hysteresis connection (default setting 100%, setting range 70 to 150 %):
This value defines the switch-on criterion of the controller. This means the controller would switch on at
100% missing compensation power in relation to the smallest automatic capacitor stage of the facility.
Hysteresis disconnection (default setting 100%, setting range 70 to 150 %):
This value defines the switch-off criterion of the controller. This means the controller would switch off at
100% overcompensation power in relation to the smallest automatic capacitor stage of the facility.
Alarm delay (default setting 1200 seconds, setting range 0 to 3000 seconds):
This value defines the time until the message Facility too small is displayed. In case the set alarm
CosPhi is not reached despite all available stages switched on, this message is displayed after the set
alarm delay time has elapsed.
Idle time (default setting 30 seconds, setting range 0 to 300 seconds):
This value defines the time the controller is idle after compensation before another switching
operation is performed (connection or disconnection).
Switching interval (default setting 8 seconds, setting range 0 to 10 seconds):
This value defines the time the controller is always idle between two switching operations.
Alarm CosPhi (default setting ind. 0.92, setting range ind. 0.70 to 1.0):
This value is connected to the message Facility too small. If this value is not reached after the alarm
delay has elapsed despite all stages switched on, the message Facility too small is displayed
Attenuation Qmiss (default settings 2, setting range 0 to 9):
This value defines how much the display is attenuated to prevent fast parameter changes of the
missing compensation power.
Attenuation U (default settings 2, setting range 0 to 9):
This value defines how much the display is attenuated to prevent fast parameter changes of the
measurement voltage.
Attenuation I (default settings 2, setting range 0 to 9):
This value defines how much the display is attenuated to prevent fast parameter changes of the
measurement current.

Caution!
However, you have to check all parameters to make sure that there are
no deviations from the requirements the facility has to fulfill.
