4. High DC output voltage.
A
.
Check battery voltage for proper number of cells.
B. Check control fuse in unit.
C. Float/Equalize voltage potentiometers not set properly. (See Float/Equalize adjustment procedure
for proper voltage setting.)
D. Disconnect battery and loads from rectifier output terminals, put F/E switch in the float position,
and apply AC input voltage to rectifier. If DC voltage raises above 2.5 Vp.c., circuit regulator assembly
may be defective.
5. Check for shorted power diodes or diode modules (SD1). (See diode troubleshooting page)
6. H.V shutdown improperly set, too low.
7. Open gate or wire on triac TR-1.
12.3.2 Open DC Protection.
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 DC breaker or DC fuse.
12.3.3 Charger operates but output voltage/current is low.
Possible Cause:
1. Float/Equalize voltage potentiometers not set correctly (see float/equalize adjustment procedure
for proper voltage setting).
2. Check power diodes or diode modules and triac (see diode and triac troubleshooting procedure).
3. Regulator assembly board is defective. (replace as required)
4. Defective DC voltmeter/ammeter.
5. Unit in current limit.
6. Resonating capacitor open.
