This switcher performs self-diagnostics when you turn
the power on or reset the switcher, and at regular
intervals during operation. If the self-diagnostics
detect an error, the status indicator lights, and
information about the error is output to the terminal.
You can easily determine the origination of the error
through the 2-digit error code shown on the ERROR
No. indicator on the CPU-339 board.

The errors that may be displayed on the front-panel
status indicators and their respective countermeasures
are shown in the table below.
Refer to the installation manual for information concerning
the error codes displayed on the ERROR No. indicator and
the appropriate countermeasures.
