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.
