Operational Failure Messages
Failures in the general operation of the instrument are indicated by the
following diagnostic messages:
[POWER] [FAILED]
This is the first display to appear after power-up if the power-up message
was not suppressed in BASE CFG MENU. It indicates that the power has
been off due either to a normal shutdown or an accidental power failure.
Pressing any key clears this message and starts the operating display
sequence.
[BUS INHB], [CMP ERB], [BUS ERR], [OVERCFGD]
These messages identify communication problems. They are described
in the Modbus Communications Supplement, IB-23C650M.
