12.5 Spurious Fault Reporting
Due to external factors some reported faults may be spurious, variable or unstable, typically showing high numbers of faults
that are difficult to locate or diagnose. E.g. if a short or open circuit occurs in a remote location the communication ring may
appear to operate normally or ring operation and fault reporting may be intermittent and transient. These faults can be
difficult to diagnose, especially if a cable has degraded over time and/or where moisture ingress may be a factor.
If in doubt:
• Check if the occurrences correspond to ambient conditions such as rain, high humidity or dew point.
• Check the connections and wiring at remote cabinets and cable joints, and then work backwards toward the Controller
while checking for degraded, damaged or shorted wiring, particularly within exposed cable runs.
• Refer to the Touchpoint Pro Technical Handbook Ring Fault Diagnostics and Debugging Techniques.
