Troubleshooting
Chapter 5 furnishes a Troubleshooting Chart, diagnos-
tic flow charts, a power supply integrity test, and in-
formation to correct possible water problems.
5.1 Before Calling
IEI
Whenever your prox.pad plus unit experiences diffi-
culty, before calling IEI for help, first refer to the
Troubleshooting Chart for answers
. If the Trou-
bleshooting Chart does not help, perform the follow-
ing:
1. Write down the time and date that the problem
occurred, or the time and date when you first
noticed the problem. Also note what the unit was
doing when the problem occurred or was first
noticed.
2. Note all other relevant information, paying par-
ticular attention to recent updates, new or inex-
perienced installers/programmers, or any recent
hardware changes.
3. Attempt to isolate the problem.
4. Refer to the “Troubleshooting Chart” and flow
charts in this chapter. They are designed such that
many common problems can be easily diagnosed
and corrected by users without IEI assistance.
5. Contact your supervisor or the “technical subject
expert” at your facility for assistance for help if
you cannot diagnose and correct the problem
yourself using steps 1-4 above
6. Contact IEI for help only if using steps 1-5 above
fails to resolve the problem. Make sure that you
have a written description of the problem (and
any steps you may have taken attempting to rem-
edy the problem) before calling for help. Write
