Maintenance Instructions
1. For flooded lead-acid batteries, regularly check water
levels of each battery cell after charging and add dis-
tilled water as required to level specified by battery
manufacturer. Follow the safety instructions recom-
mended by the battery manufacturer.
2. Make sure charger connections to battery terminals are
tight and clean.
3. Do not expose charger to oil or to direct heavy water
spraying when cleaning vehicle.
Battery Charger Fault Codes
If a fault occurred during charging, the red "Fault" LED will
flash with a code corresponding to the error. Refer to the
table following for the flash codes and their removal.
Table 3-3. Battery Charger Fault Codes (Delta-Q)
Flash(s) Fault Fault Removal
1
Battery voltage
high
Auto-recover - Indicates a high battery pack voltage
2
Battery voltage
low
Auto-recover - Indicates either a battery pack failure,
battery pack not connected to charger or battery volts
per cell is less than 0.5 VDC. Check the battery pack and
connections
3
Charge
time-out
Indicates the batteries did not charge in the allowed
time. This could occur if the batteries are a larger capac-
ity than the algorithm is intended for or if the batteries
are damaged old or in poor condition.
4 Check battery
Indicates the batteries could not be trickle charged up to
the minimum voltage per cell level required for the
charge to be started.
5
Over-
temperature
Auto-recover - Indicates charger has shut down due to
high internal temperature
6 QuiQ fault
Indicates that the battery will not accept charge current,
or an internal fault has been detected in the charger. This
fault will nearly always be set within the first 30 seconds
of operation. Once it has been determined that the bat-
teries and connections are not faulty and fault 6 is again
displayed after interrupting AC power for at least 10 sec-
onds, the charger must be brought to a qualified service
depot.
