Error Messages
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 is
stored in the power supply's error queue. The power supply beeps once each
time an error is generated.
• 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.
• If more than 20 errors have occurred, the last error stored in the queue (the
most recent error) is replaced with -350,
“Too many errors”
. No additional
errors are stored until you remove errors from the queue. If no errors have
occurred when you read the error queue, the 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.
•
