MAINTENANCE
Replace capacitor if can is ruptured or fails test. Refer to Capacitor Testing in Maintenance chapter.
Check line voltage for connection to proper input voltage.
Refer to Line Voltage Changeover instructions in Installation chapter.
Check battery for one or more defective cells.
Less than rated output on fully discharged battery (approximately 1/2 rated output) (3-phase
chargers only)
Check for either a shorted transformer, or wiring short circuit.
Replace as necessary.
Charger does not shut OFF automatically or start automatically
Check Charge Control.
1. If charger does not start automatically, check for 24 volts AC between the red-white lead and
the red-black wire of control transformer T1. If 24V AC is present, connect a jumper from the
red-white lead of control transformer T1 to the red lead of contactor K1 coil. If charger
starts, check further for faulty printed circuit card on control and replace as necessary.
2. If charger does not stop automatically when equipped with pt/dv/dt control,
check to be sure charging voltage rises above 2.37 volts/cell during the cycle. If not, see low
charging current or less than rated output above. If battery on-charge voltage rises above
2.37 volts/cell during the cycle, check for defective control printed circuit card.
