If you use the optional fault location function, it is recommended that you enter the data
for the protected cable stretch directly after installation under
Settings
Fault
location
. The fault location algorithm needs this data to calculate the distance to the
fault location when a circuit breaker is tripped.
If the license key required to activate the “fault location” option has not yet been entered,
access to the menu is blocked and instead the following screen appears:
The license key to be entered can be found on the nameplate (see page 18) on the back
of the supply module. If the license was purchased directly with the device, it can be
ordered at any time (see page 10).
After entering the license key, it must be saved using the
button. The basic settings
should then also be overwritten (see page 45) to save the license key permanently.
When the
Settings
Fault location
is opened the next time, the
Cable type
screen should now be available.
Proceed as follows to enter the cable data:
Step Action
1
Look for the correct cable type and tap a conductor to activate it. In doing this, it
is not the designation of the conductor but its position relative to the neutral
conductor (adjacent or opposite-lying) that is of key importance for locating
cable faults.
2
Enter the conductor cross-section, the cable length and, if necessary, the
neutral conductor cross-section.
3
Save the settings using the
button.
