This section provides information about system such as error message querying, beep
settings, display control, OCP delay setting, Style and power supply identity querying. Most of
the items in System Operation provide information for servicing procedures.
3.11.1 Error States
Once an error occurs, the ERR indicator is lit. Errors can be generated by invalid operation or
hardware failure. A record with up to 32 errors is saved in the power supply's error queue. For
more information, please refer to the following instructions and the chapter
Errors are retrieved in a first-in-first-out (FIFO) sequence. The first returned error is the
first saved error. When all of errors are read from the queue, there will be no ERROR
symbol shown on the display.
When more than 32 errors have occurred when operating the power supply over the
remote control, the last error saved in the queue (the most recent error) will be replaced
with -350,Too many errors. After removing the errors from the queue, you can save the
next error. If there is no error when you read the error queue, the power supply shows
"NO ERROR" on the display, or responds with +0,No errors over the remote control.
You can clear the error queue when turning off the power supply or after commanding a
*CLS (Clear Status). Please note that the *RST (Reset) doesn't clear the error queue.
