Fault Codes
2. Correctional Faults
Code 12
CELL MISMATCH
(POOR NEG. SLOPE)
Code 15
TARGET CAPACITY
NOT MET
Over-rated batteries
•
Correctional Faults allow the program to proceed but
result in a Fault Code as a caution to the user.
Note Batteries with correctable faults may improve with
the PRIME or AUTO program. If the battery is corrected
as a result of the programs, the Fault Code changes to
Corrected Fault Code. Refer to "6. Corrected
Faults" in
this Chapter.
Reason Cells are mismatched. The cells reach full charge at
different times. This deficiency reduces the negative slope
effect on the NiCd. The charge cycle is terminated
by the
Plateau Timer. The program proceeds to the next cycle as
normal. For SLA , the plateau charge time-out occurred before
specified full charge conditions were met
Battery type Code 12 only applies to NiCd batteries.
What to do If the capacity reading is acceptable, continue
using the battery. Monitor the performance of the battery. •
Reason Final capacity is below target. Code 15 is shown at
the conclusion of the program. Possible reasons:
• Battery is overrated
• Memory effect on NiCd due to lack of maintenance
• Battery has been damaged by a poorly designed charger
that heat up battery causing the battery to overheat.
• Old age
Battery Type Code 15 applies to all batteries
What to do NiCd's with memory may be corrected with the
AUTO program. If all else fails, discard battery.
It has been noted. that some battery manufacturer over-
rate their batteries. When you service these batteries at
over-rated discharge currents, the capacity readings will
be disappointingly
low.
Do not blame the C4000 for the
low readings!
Rather, contact your vendor.
