What This Code Means
A condition indicating a short circuit or interruption on the connection line, which may cause the system to isolate segments of the loop using group separators.
Common Causes
1Interruptions or interchanged connections in the connection line
2Damaging the line due to insufficient bending radii
3Loop is too long or attenuation too high
Resolution Steps
Check for interruptions or interchanged connections in the connection line, damaging the line due to insufficient bending radii, or the loop being too long or attenuation too high. In the event of a short circuit within the loop, the cut-off relays of the corresponding group separators open and isolate the affected segment; isolated detectors are listed in the plain text display together with the fault parameter >Com. error<.
