6.0 MAINTENANCE AND TROUBLESHOOTING
6.1 MAINTENANCE
PowerPac power supplies require very little maintenance to assure reliable operation. During normal opera-
tion, spills and splashes may cause residues to form on the case. Unplug the power supply. Use a damp
cloth to wash down the outer case. Avoid wetting the connectors located below the front panel and on the
rear of the unit.
6.2 TROUBLESHOOTING
If a system or operator error occurs, the appropriate error message will appear on the LCD display. The
power does not operate when an error message is displayed.
If a no-load or rapid change in resistance error is inadvertently activated, it is possible to temporarily deacti-
vate it. To deactivate, press the number
6
key and the
STOP
key simultaneously to access the deactivation
menu.
