13.0 SCRFLX TROUBLESHOOTING
1.Symptom => NO DISPLAY INDICATION AFTER CONNECTION OF AC POWER
Possible Cause Action
1.1
Charger connected to low AC voltage. Verify AC voltage per nameplate of the charger
and electrician’s tag.
Verify connection of primary windings of power
transformer and AC fuses of charger per
connected AC voltage and electrician’s tag.
1.2
Charger connected to high AC voltage. Verify AC voltage per nameplate of the charger
and electrician’s tag.
Verify connection of primary windings of power
transformer and AC fuses of charger per
connected AC voltage and electrician’s tag.
Check AC fuses of charger and replace if
needed.
Check fuse F2 of Control Card. If this fuse is
blown, replace Control Card.
2. Symptom => DISPLAY INDICATES FAC OR F3 AFTER CONNECTION OF AC POWER
Possible Cause Action
2.1
Charger connected to low / high AC voltage. Verify AC voltage per nameplate of the charger
and electrician’s tag.
Verify connection of primary windings of power
transformer and AC fuses of charger per
connected AC voltage and electrician’s tag.
2.2
AC power partially missing. Verify AC voltage at all primary windings of
power transformer and AC fuses of charger per
nameplate of the charger and electrician’s tag.
2.3
Failure of one or more of charger’s power fuses. Consult GNB technician.
Replace fault fuse. Verify input AC voltage and
output High Rate current.
2.4
Phase rotation. (Only if F3 is showing) Verify phase sequence of input AC source.
Ensure that it follows the sequence indicated at
the charger’s input.
3. Symptom => DISPLAY INDICATES FDC BEFORE CONNECTION OF BATTERY .
Possible Cause Action
3.1 Charge cycle was interrupted during charge by
DC cable disconnection with slow / bouncing
disconnection of DC plug. Do not interrupt charge by DC cable
disconnection. Use pushbutton Stop for this
purpose. Disconnection of DC cable during
charge is not safe because it produces
electrical arc.
If DC cable disconnection is used, disconnect
cable as fast as possible; never connect battery
before indication OFF appears at display (takes
about 2 s after disconnection of DC cable).
Disconnect battery and AC power for 5 sec.
Return AC power and then connect battery.
3.2
Charge cycle was interrupted by DC cable
disconnection during charge. Additionally, a
battery was connected back before charger
displayed OFF.
Indication FdC and FAULT LED is on. See above
