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:
