12.3 SYMPTOMS & CAUSES
12.3.1 A.C. Breaker trips.
Possible Cause:
1. Wrong a.c. input voltage.
2. The a.c. input taps on power transformer set incorrectly.
3. (See schematic wiring diagram)
4. An a.c. to d.c. short or a.c. or d.c. short to ground (see ground short circuit test).
5. High d.c. output voltage.
• Check battery voltage for proper number of cells.
• Check control fuse on alarm interface board.
• Float/Equalize voltage potentiometers not set properly. (See Float/Equalize adjustment procedure
for proper voltage setting.)
• Disconnect battery and loads from rectifier output terminals, put F/E switch in the float position, and
apply a.c. input voltage to rectifier. If d.c. voltage raises above 2.5 v.p.c., circuit regulator assembly
or “informer” option may be defective.
6. Check for shorted power diodes or diode modules (SD1). (See diode troubleshooting
page)
7. H.V. shutdown improperly set, too low, “informer” option.
8. Open gate or wire on triac TR-1.
12.3.2 Open D.C. Fuse.
Possible Cause:
1. Shorted power diode or diode module (repair/replace as required).
2. Shorted battery cells or customer equipment.
3. Shorted output cables.
4. Capacitors not precharged.
5. Shorted C3 capacitors.
6. Loose connections on the d.c. fuse.
