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 predened for the following programmed stage
powers. However, these must be checked and corrected if they dier from the capacitor
specications.
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
