 Switching interval (default setting 50ms, setting range 50 to 9999ms): This
value de nes the time the controller is idle between two switching opera-
tions.
 Alarm cos phi (default setting ind. 0.92, setting range ind. 0.70 to 1.0): This
value is connected to the message PFC too small. If this value is not reached
after the alarm delay has elapsed, despite all stages being switched on, the
message PFC too small is displayed.
 Attenuation Q
miss
(default setting 0, setting range 0 to 9): This value de nes
the attenuation of the display and control behavior to prevent rapid parame-
ter changes if compensation power is missing.
 Attenuation U (default setting 0, setting range 0 to 9): This value de nes the
display attenuation to prevent rapid parameter changes of the measuring
voltage.
 Attenuation I (default setting 0, setting range 0 to 9): This value de nes the
display attenuation to prevent rapid parameter changes of the measuring
current.
NOTE
Due to the default settings for the discharge time (20ms) and switching inter-
val (50ms), an attenuation set subsequently (default setting 0) has no e ect.
The attenuation value set is only applied if the capacitor discharge time and the
switching interval of the stages is greater than100 ms.
