2. Remove the unconfigured or foreign modules
3. Clear the ring fault from the system
4. Refit the unconfigured or foreign modules in turn and
continue with commissioning
5. See Chapter 19 Ring Communication Errors
Check power supply / wiring, check fuses. Check RCD
and UPS/Battery Backup if fitted.
See Chapter 19 Ring Communication Errors
Check the Active Events screen for details of the
location of the connection break.
or
Check the LEDs on each Ring Coupling Module (RCM)
in the system. The LED flashes to indicate that data is
being received, therefore if an LED is not lit, there is a
problem in the preceding section of the ring network.
LEDs on the Ring coupling module indicate the
presence of an incoming signal and they do not take into
account the quality of the incoming signal.
Check the cables and connections in the area where the
fault is indicated.
Refer to Ch.13.14 Managing the Integral SD Card and
replace the SD Card.
