Error Messages
Errors are retrieved in first-in-first-out (FIFO) order. The first error returned
is the first error that was stored. Errors are cleared as you read them over the
remote interface. When you have read all errors from the queue, the
ERROR
annunciator turns off and the errors are cleared. The power supply beeps once
each time an error is generated.
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 by the
*CLS
(clear status) command or when power
is cycled. The errors are also cleared when you read the queue.
The
*RST
(reset command) command does not clear the error queue.
• Front-panel operation:
Press (
Local) key to return to front-panel operation mode if the power
supply is in remote operation mode.
If the
ERROR annunciator is on, press key to view the errors. Use the
knob to scroll through the error numbers. Press to view the text of the
error message. Press or key to decrease or increase the scrolling
speed of the text on the display. All errors are cleared when you exit the menu
by pressing the key or let the display time out for about 30 seconds.
