When an abnormal condition is detected in the battery, the charger may switch to one of several special charging
modes to overcome the detected abnormal condition or enter standby mode and flash a warning on the display to
explain why charging is suspended. Below are conditions that cause the charger to interrupt Auto Mode charging.
If the battery has a low starting voltage (<10.5V), the charger will automatically enter SOFT START
mode. This mode reduces the charging current to 5 Amps to allow the battery to recover from a deep
discharge, before resuming Normal Auto Mode charging once battery voltage rises to a normal value.
Below is an example of the display in SOFT START Mode.

SOFT START
If the battery's voltage starts at a low value and increases extremely rapidly, the charger will automatically
enter BATTERY REPAIR Mode. BATTERY REPAIR Mode reduces the charge rate to no more than 10 Amps
and maintains an elevated charging voltage to allow the battery to recover its capacity to be charged fully.
After the battery begins to accept normal charging current, Normal Auto Mode charging automatically
resumes. Below is an example of the display in BATTERY REPAIR Mode.

BATTERY REPAIR
If the charger continues in BATTERY REPAIR Mode for 6 hours without the battery accepting normal
charging current, charging will stop and the fault light will be lit. Below is an example of the display after a
BATTERY REPAIR timeout.

The charger incorporates Smart Clamp Technology and will send power to the output leads only when a
proper battery connection is detected. If an incorrect connection is detected, the fault light will be lit and an
error message will appear on the display. Below is an example of the display when the charger detects an
improper connection.
*********Warning*********
Battery Cables
Reversed
Sometimes a deeply discharged battery can cause the charger to determine there is no battery connected
(or that the battery is shorted) and prevent the charger from starting Auto Mode charging. This safety
mechanism can be overridden. Before proceeding, check all charger settings and vehicle connections
(remembering that you should disconnect from the AC power supply prior to disconnecting or reconnecting
the output leads). Below is an example of the display when this condition occurs.
