Ring Oscillation
Fault
Ring faults are present
or have occurred on
the system when
commissioning a
module or ring circuit.
This may occur
when all modules
are unconfigured,
some modules are
unconfigured, or
some modules
are foreign
(unrecognised)
modules
Remedial action:
1. Take the unconfigured or foreign modules out of the system
2. Clear the ring fault from the system
3. Insert the unconfigured or foreign module back in the system
and continue with commissioning.
