[3 FLASH] Charge Timeout: Indicates the battery did not
charge within the allowed time. This could occur if the bat-
tery is of a larger capacity than the algorithm is intended for.
It can also occur if the battery pack is damaged, old, or in
poor condition. In unusual cases it could mean charger out-
put is reduced due to high ambient temperature.
[4 FLASH] Check Battery: Indicates the battery pack could
not be trickle charged up to the minimum 2 volts per cell
level required for the charge to be started. This may also
indicate that one or more cells in the battery pack are
shorted or damaged.
[5 FLASH] Over-Temperature: auto-recover. Indicates char-
ger has shutdown due to high internal temperature which
typically indicates there is not sufficient airflow for cooling –
see step 1 of Installation Instructions. Charger will restart and
charge to completion if temperature is within accepted limits.
[6 FLASH] QuikQ Fault: Indicates that the batteries 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 batteries and connections are not faulty and Fault 6
is again displayed after interrupting AC power for at least 10
seconds, the charger must be brought to a qualified service
depot.
