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 erros 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 erros 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) command
does not clear the error queue.
• Front-panel operation:
If the
ERROR annunciator is on, press the key repeatedly to read the
errors stored in the queue. The error queue is cleared when you read all errors.
• Remote interface operation:
