Fault Location
Options
Besides the display at the device and in DIGSI
®
there are additional display options
available in particular for the fault location. They depend on the device version, the
configuration and allocation:
• If the device features the BCD output for the fault location, the transmitted figures
mean the following:
0 to 195: the calculated fault location in % (if greater than 100%, the error lies
outside the protected line in a forward direction);
197: negative fault location (fault in reverse direction);
199: overflow.
Retrievable
Indications
The indications of the last eight network faults can be retrieved and output. In total 600
indications can be recorded. Oldest indications are erased for newest fault indications
when the buffer is full.
Spontaneous
Indications
Spontaneous indications contain information that new indications have arrived. Each
new incoming indication appears immediately, i.e. the user does not have to wait for
an update or initiate one. This can be a useful help during operation, testing and com-
missioning.
Spontaneous indications can be read out via DIGSI
®
. For more information see the
SIPROTEC
®
4 System Description.
General

®
4 device can be retrieved via DIGSI
