Troubleshooting Procedure
Troubleshooting should be performed only by trained service personnel or experienced electricians. Before setting
up any complicated testing, give the unit a general inspection.
Check the following:
1. Check DC input-output cables, connections, battery type, and number of batteries/cells against the
unit's rating.
2. Check unit specifications against customer order.
3. Check AC input connection and input voltage connected.
4. Measure AC voltage if power outage occurred. If the charger is in 105VAC-119VAC range, press reset
button to restart. The charger restart automatically at 120VAC after power outage.
5. Check for shipping damage, loose connections, broken wires, etc.
6. Certain failures can be caused by defective batteries; make sure batteries are free from defects.
When calling in for a service inquiry or for troubleshooting assistance, be sure to have all of the following
information on hand:
1. Equipment model number and serial number.
2. The actual AC input voltage.
3. The DC output voltage with and without the battery.
4. The actual DC output current and voltage, measured with battery connected to charger.
NOTE:
When ordering replacement parts, drawings, or schematics, always give model number and serial
number
