TROUBLESHOOTING
Troubleshooting should be performed only by trained service personnel or experienced electricians.
CAUTION: Hazardous a.c. and d.c. voltages are present within the rectifier
cabinet.
Equipment:
The only equipment required is a multimeter for voltage or resistance readings and analog ohmmeter
12.1 GENERAL INSPECTION
On servicing new equipment, before setting up any complicated testing or jumping to any conclusions,
give the unit a general inspection. Check the following:
1. Check d.c. output cables, connections, battery type, and number of battery cells with rectifier
rating.
2. Check unit specifications with customer order.
3. Check input connections, input voltage and line breaker size.
4.
Check for shipping damage, loose connections, broken wires, etc.
5. Certain failures can be caused by defective batteries and customer loads; make sure batteries and
loads are free from defects.
NOTE : If the problem is found to be located in the printed circuit boards, the board should be replaced.
No attempt should be made to repair circuit boards in the field.
12.2 SERVICE INFORMATION
Information you should have when calling in for troubleshooting assistance:
1. Equipment model number and serial number.
2. The actual a.c. input voltage.
3. The d.c. output voltage with and without the battery.
4. Result of the check of a.c. breaker and d.c. output fuse.
5. The actual d.c. output current and voltage when measured with battery and load connected to
rectifier.
