3. SERVICING THE AT30

3.1. A STEP-BY-STEP TROUBLESHOOTING PROCEDURE

The AT30 is fully tested and calibrated from the factory, and should work
for years with a minimum of attention. If you do encounter trouble, there
are three (3) steps you should take to identify the problem and return the
AT30 to service.
1. Check the front panel meter for an error code. The microprocessor control
circuitry is able to diagnose common problems with the AT30, or with the
installation or application. If the front panel displays an error code, see
Section 3.2, Interpreting Front Panel Error Messages, for help in
interpreting the code and solving the problem.
2. If the AT30 does not work properly, but there is no front panel error code,
shut the unit down. Turn off (open) both front panel circuit breakers, and/or
lock out ac and dc power externally. Restart the AT30 by restoring dc
power first, followed by ac power second. This will return the AT30 to
normal operation as long as there is no internal component failure.
Perform Step 2 only once. If the AT30 does not resume
normal operation, go on to Step 3.
3. If the AT30 still does not work properly, make a list of the symptoms that
you observe. Turn to Using the troubleshooting chart in Section 3.3. The
troubleshooting chart relates common trouble symptoms to their causes, and
gives the proper procedures for correcting the problem.
4. If the symptom does not appear on the troubleshooting chart, or if the
recommended repair does not work, consult your sales or service
representative to arrange for on-site or factory service.
