SECTION 3 - MACHINE CONTROLS, INDICATORS AND OPERATION
[3 FLASH] Charge Timeout: Indicates the battery did
not charge within the allowed time. This could occur if
the battery 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 output 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.
3-6
[5 FLASH] Over-Temperature: auto-recover. Indicates
charger has shutdown due to high internal tempera-
ture which typically indicates there is not sufficient air-
flow for cooling – see step 1 of Installation
Instructions. Charger will restart and charge to com-
pletion 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 dis-
played after interrupting AC power for at least 10 sec-
onds, the charger must be brought to a qualified
service depot.
