During any abnormal conditions, there are several error messages that could be
indicated in the display. When an abnormal condition occurs the output will
disable and the alarm will sound. The Test/Reset LED indicator will also begin
flashing. Pressing the Test/Reset key will reset the audible alarm and the
abnormal condition will be displayed.
All error messages occur in abnormal conditions and
therefore must be recorded. Check the cause of the error to ensure the problem
is eliminated before restarting the operation, or contact Associated Power
Technologies, Inc., or our official distributors for further assistance.
