Functional principle
The settings are saved on an EEPROM so that they are not lost in the event of a power
failure.
The measuring cycle of the controller used to record the necessary network parameters
takes approx. 20 ms.
NOTE
Limit for overvoltage switch-o = measuring voltage + 10% (taking the measuring volt-
age ratio into account). This value cannot be changed and serves to protect the compen-
sation system.
In the event of an error, the compensation stages are switched o. The alarm relay switch-
es and "Overvoltage" is displayed.
CAUTION
The discharge times are automatically predened for the following programmed stage
powers. However, these must be checked and corrected if they dier from the capacitor
specications.
Capacitor power Discharge resistance Discharge time
0.1 kvar – 9.9 kvar 300 kOhm 60 seconds
10 kvar – 19.9 kvar 300 kOhm 120 seconds
20 kvar and above 300 kOhm 180 seconds
