1. Application Tables
The CADEX C4000 is capable of identifying battery
deficiencies and faults. These characteristics
are
categorized in Fault Codes. Explanation of the Fault
Codes are shown on the display upon request.
The Application Table on the following pages
summarizes the Fault Codes. Further explanations
of
each code are described in the subsequent paragraphs.
Fault
Definition Reason Battery What to do
Code
Chemistrv
12
Cell mismatch
No adequate Negative Slope NiCd Battery is serviceable.
Observe performance.
15
Target Capacity not met
Inadequate performance NiCd, NiMH,
Use AUTO for NiCd. If all
SLA fails, discard battery.
18
Charge current reduced
•
New battery, not formatted NiCd, NiMH Battery may correct itself
•
Prolonged storage
with use.
•
Charge current too high
20 High battery impedance
High battery voltage during NiCd. NiMH, Battery not serviceable
charge SLA
21/22 Shorted or reversed
•
Battery totally discharged NiCd, NiMH
• Charge prior to service
•
Reversed battery leads
• Reverse Polarity
•
Battery shorted • Discard battery
23/24
Very low voltage Some cells are shorted. Mainly NiCd Discard battery
1 min and 10 min time-out
.
25 Low voltage, cell mismatch
Shorted and Uneven cells. NiCd
Discard battery
Charge terminated by Plateau
Timer
26 Low voltage, cells are Shorted cells. Charge
NiCd
Discard battery
matched
terminated by negative slope
27 Low voltage, charge time- Battery too large for allotted NiCd, NiMH Check C-Code setting. If
out charge time correct, discard battery.
28
Soft battery Battery voltage rises too high NiCd. NiMH
Try again. Discard if battery
during charging
fails again
29
Intermittent battery
•
Poor electrical contact NiCd, NiMH Check C-Code setting and
•
Faulty cell
contacts. Discard if all fails.
