10 F3 Low Battery Override, Jumper Settings

Note: F3 and F4 clear automatically if the battery voltage falls within acceptable limits. All indications except F8, F9 and F10 can be cleared by disconnecting the battery. For F8, F9 and F10, correct the condition that caused the indication and disconnect the battery to clear the indication.

CAUTION: If F8 is showing, and the charger is providing current to the battery, remove AC power from the charger before disconnecting the battery.

2.1.10 F3 (Low Battery) Override

If battery voltage is below 1.60 volts per cell the charger does not start automatically. If this is due to an overly discharged battery of the correct voltage, the F3 indication can be manually overridden by pressing ‘STOP’ while the F3 message (Low Battery) displays.

2.1.11 Jumper Settings

CAUTION: Remove AC and DC power from the charger before changing any jumper settings. Refer to figure 1 for location of jumpers.

- Jumper J5 should be set to match the battery voltage.

Volts 80V 72V 64V 48V 36V 24V 12V1 SP2

1For non-standard battery voltages above 80V, the jumper is set on 12 and a resistor is installed in the charger wire harness based on the following calculation: R = 1250 x (Nominal Battery Voltage) – 15000.

2For non-standard battery voltages between 12V and 80V, the jumper is set on SP and resistor R9 is installed on the control based on the following calculation: R9 = 1250 x (Nominal Battery Voltage) – 15000.

-Jumper J4 is used to lock out several parameters in the programming mode.

-Header J1 is used to select the charger type.
