3. SERVICING THE AT10.1
3.1. A STEP-BY-STEP TROUBLESHOOTING PROCEDURE
The AT10.1 battery charger is fully tested and calibrated at the factory and
should work for years with a minimum of attention. If you do encounter
trouble, there are three steps you should take to find the problem and
return the charger to service.
1. Check the front panel meter for an error code. The AT10.1 is able to
diagnose common problems with the battery charger, or with the application
or installation. 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 charger does not work properly, but there is no front panel error code,
turn off the front panel circuit breakers (or disconnect ac and dc power
externally). Then turn the dc and ac power back on. This will return the
charger to normal operation as long as there is no internal component failure.
Note: Do this only once. If the charger does not resume
normal operation, go to the next step.
3. If the charger still does not work properly, make a list of the symptoms that
you observe, then 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 doesn't appear on the troubleshooting chart, or if the
recommended repair doesn't work, consult your sales or service
representative to arrange for on-site or factory service.
