6.3.10 Battery Loses Charge

Battery charger could be bad, there could also be too large of a load on the battery. Change the battery or

lessen the load.

The battery charger float voltage could be too low (if equipped with battery charger). Call your dealer or

distributor.

6.4 15/12-Amp Battery Charger Troubleshooting and

Faults

The 15/12-amp battery charger includes one set of Form-B alarm contacts (corresponding to the status

LED on the control panel). When red, this LED indicates a fault condition. The control panel also displays

fault codes.

When a fault occurs, the red fault LED lights and a brief description of the fault and the numeric fault code

is displayed on the digital display. To correct the fault, find the fault code number and take the suggested

corrective actions. If the problem persists, call an authorized Cummins Inc. distributor for help.

6.4.1 Clearing Faults

Most displayed faults are cleared by removing the fault. However, faults 379 - OVER CURR, 442 - HIGH

BATT VOLT, and 9115 - BATT FAIL can only be cleared by cycling completely through the Setup menus

or by powering down the charger after the fault is corrected. (More information on Setup menus is

included in the Battery Charger Operator's Manual.)

6.4.2 Fault Alarm Output Connector

The battery charger includes a fault output relay that is activated (contacts close) when faults occur. The

contacts are rated at 2 amps/30 VDC. This feature can be used by wiring a fault indicator to the fault

alarm output connector located on the front of the battery charger. A 2-pin plug connector (323-1678-02) is

shipped with the 15/12-amp transfer switch battery charger.
