12.2 Charger LED Faults
The charger will indicate when a fault occurs by using different patterns of the Fault (Red), Charge St atus
(Yellow), and Charge Complete (Green) LEDs as explained in t he t able below. Using t he ChargerConnect

DC DIS CONNE CT
– DC disconnect detected
via the third-pin, but DC (battery ) voltage is
still present at the charger output. (Third-pin
DC disconnect sensing is an optional feature
available with supported DC plug/receptacle
systems to minimize charger output inhibit
time when a DC disconnect occurs during
charging.)

– Maximum temperature was
met. Charge cycle was halt ed and will restart
when the temperature decreases.

LOW TEMP
– Temperature is too low to start
a charge cycle (< -25°C). Charging will start
when temperature increases.
