TROUBLESHOOTING

Under normal operation, the

Status OK

LED

(green) is lit. In case of a fault, the

Status FAULT

LED

(red) is lit. If that occurs, perform the following:
1. Note the fault message that appears on the screen.

Make sure to note the second line of the

fault message as it indicates the type of fault. It is important to note the fault message precisely

as that will help identify the cause of the fault so that a fix can be quickly found.

2. Open the charger louvered front door and note if any of the charging drawers has a

RED LED

light

(upper left corner of the front panel of the charging drawer). The charging drawer(s) with a

RED

LED

is (are) the one(s) that initiated the fault.

I. Charger

Not

Operational

When the charger is first turned on, with the main disconnect power switch in the

ON (CW) position,

the LCD should be ON with the

CHARGER IDLE message displayed.

If the problem persists, perform the following:

A. Turn off the unit. Main disconnect power switch should be in the OFF (CCW) position
B. Ensure proper AC wiring
C. Ensure the main AC disconnect (wall) is energized
D. Verify fuses in main AC junction box (wall)
E. Using an AC voltmeter, verify that the supply voltage for all three phases (AC mains

line to line) matches the specification for the charger and are within the charger

tolerances.

After going through the checklist above, restart the unit once more. If the problem persists, contact

the local GNB Industrial Power service representative.

DO NOT ATTEMPT TO SERVICE THE UNIT.
