Description of the display window
Switching interval (default setting for thyristor stages 50 msec, setting range 50 to 9999
ms, for contactor stages 8 sec, setting range 0 to 10 sec):
This value defines the time the controller is idle between two switching operations.
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 2, setting range 0 to 9):
This value defines the attenuation of the display and control behavior to prevent rapid
parameter changes if there is no compensation power.
Attenuation U (default setting 0, setting range 0 to 9):
This value defines the display attenuation to prevent rapid parameter changes of the
measuring voltage.
Attenuation I (default setting 2, setting range 0 to 9):
This value defines the display attenuation to prevent rapid parameter changes of the
measuring current.
NOTE
Due to the default settings on the discharge time (20 ms) and switching switched (50 ms)
for thyristor stages, an attenuation set later on (default setting 0) does not have any
effect. The attenuation value set is only applied if the capacitor discharge time and the
switching interval of the stages is greater than 100 ms.
