Field power from one or more
of the redundant sources is
missing or a field error is
detected. A field error may be
an open load or an out-of-
compliance error.
To isolate the missing power source, use
the TriStation Diagnostic Panel.
To determine the actual state, use a
voltmeter, then correct the problem in the
external circuit.
If these steps do not solve the problem,
replace the module.
