PROGRAMMABLE AC POWER SOURCE 230
--------
Notes
------------------------------------------------------------------------------------------------------------
 The E mark does not mean it is faulty but indicates the protection operation was activated. In
some cases such as the protection operation was activated in a chain-reaction manner, the E
mark may appear on a normal power unit. A power unit is judged as faulty by checking
whether the error repeats or not after the power unit is restarted as described in the step 2.
 When the error message is "ID:54 Power Unit DCPS Undervoltage" or "ID:52 Power Unit
DCPS Error," the error is quite likely to be resolved after the power unit is restarted as
described in the step 2.

9.1.4 Protection Operation Types
When the protection function is activated or an error is detected, the product applies one of the
following five types of protection operation and error message, according to the error level.
 System Lock
The output turns off. No operations are accepted on the control panel and the remote controller. The
panel says "System Locked." To operate the product again, it is necessary to cycle the power of it.
 Output Off
The output turns off. The panel says "Output OFF" and "Press Enter Key." When you press the
ENTER key, you will return to the previous window for further operations if the cause of the error
has been removed. Otherwise, the error message window will be displayed again.
When the [PU-ON] soft-key is displayed on the error message window, pressing the soft-key opens
the power unit energization setting window. If an error repeatedly occurs, you can disable the
energization of the power unit that has the error to continue to use the product with the rest of the
power units. For details, see
9.1.3 .

off.
