Error conditions
When the front- panel ERROR annunciator turns on, one or
more command syntax or hardware errors have been
detected. A record of up to 20 errors can be stored in the
power supply’s error queue. Refer to Chapter 4, “Error
Messages” for more information.
• Errors are retrieved in first- in- first- out (FIFO) order. The
first error returned is the first error that was stored.
When you have read all errors from the queue, the
ERROR annunciator turns off. The power supply beeps
once each time an error is generated.
• If more than 20 errors have occurred when you operate
the power supply over the remote interface, the last error
stored in the queue (the most recent error) is replaced
with - 350, “Queue overflow”. No additional errors are
stored until you remove errors from the queue. If no
errors have occurred when you read the error queue, the
power supply responds with +0, “No error” over the
remote interface or NO ERRORS from the front panel.
• The error queue is cleared when power has been off or
after a *CLS (clear status) command has been executed.
The *RST (reset) command does not clear the error
queue.
Front panel operation
If the ERROR annunciator is on, press repeatedly to
read the errors stored in the queue. All errors are cleared
when you read all errors.
