11.10.2 Changing the thresholds of Service (4) Events.
The thresholds for the Events Service are given in real value, same as displayed by the instrument, and
they already take into account the CTs and VTs multiplying factors.
It is therefore essential to set the proper thresholds depending upon the type of measurement that is
made.
In order to change the configuration it is first necessary to download the existing configuration in HEX
format by means of the following command
C:\Programs\X3M\XMBF --read --ser=com1,38400,8,n,2 --addr=27 --fnum=0400 --hex
Open then the file by means of the Notepad program.
The data indicated are those of the default configuration file that is factory loaded.
The request is to configure:
the threshold for detection of Voltage Sags (Dips) or Undervoltages to:
160 Volt triggering threshold
170 Volt restore threshold
the threshold for detection of Overcurrents and Current Peaks to:
100 Amps triggering value
90 Amps restore threshold
the time duration that discriminates a Voltage Swell from an Overvoltage:
1 minute duration for discriminating a Voltage Swell
