L40, line filter monitoring

Availability of the option
This option is available for the following S120 Cabinet Modules:
● Active Line Connection Modules
Description
The line filter monitoring option is used to monitor that harmonic levels are maintained by the
filter in the Active Interface Module.
By measuring the current and voltage in the Active Interface Module, the capacitance of the
filter capacitors of the integrated filter are continuously calculated and compared with the
installed nominal capacitance.
Alarm A06250 is initiated if the calculated capacitance is higher than the set comparison
threshold.
Commissioning
To activate the comparison threshold of the nominal capacitance of the particular Active
Interface Module, you must use a script. This automatically sets the corresponding
parameters in STARTER.
The script "Option_L40_deu.txt" in German or "Option_L40_engl.txt" in English is provided on
the customer DVD supplied with the device.
Inserting the script into the STARTER project:
1. Select the Infeed unit symbol in the STARTER project using the right mouse key, select
"Expert" – "Insert script folder".
The "SCRIPTS" folder is inserted.
2. Select the "SCRIPTS" folder using the right mouse key, select "Export/import" –"ASCII
import..." and select the script "Option_L40_deu.txt" or "Option_L40_eng.txt".
Script "Option_L40" is inserted after acknowledging the following screen form.
3. Select script "Option_L40" using the right mouse key and then select "Accept and
execute".
