3.6
USB Charging Port
The UCH0054 charger has two USB ports and UCH0053 charger has six USB ports provided on the charger
which will deliver 5V/500mA power. A standard A-type USB cable can be used.
3.7
AC & DC Circuit Breakers
The UCH0053/UCH0054 chargers are equipped with manual resettable circuit breakers. These devices
protect the charger from overload conditions. The circuit breaker will open at the time of over load or short
circuit in the unit and power to the charger will be interrupted. The circuit breaker is reset by pressing the
center button.
3.8
Battery Calibration
The UCH0053/UCH0054 chargers allow for calibration of the internal fuel gauge of smart batteries. In order
to enable calibration, the user must manually press the calibration button, labeled “CAL ENABLE” below the
LED indicators. Pressing the calibration switch will begin the calibration routine for any and all batteries
connected to the charger that are requesting calibration at the time of the switch activation. If no batteries
are requesting calibration, pressing the calibration switch will force the calibration routine on all non-smart
batteries connected to the charger. A calibration cycle consists of a complete charge, followed by a
complete discharge, and finished with a complete charge. The battery calibration cycle may take up to
24hrs to complete. During the discharge portion, all 3 status LED’s will be illuminated.
3.9
Start-up & Connection Sequence
The user can either plug the UCH0053/UCH0054 chargers into a power source or attach the batteries to the
unit first. Once the batteries are attached and power applied to the unit, the batteries automatically start
charging, regardless of the order of operations.
3.10
LED Indicators
There are four groups of LEDs indicating the status of the charger. Refer to the following section for a
description of the operation of the LEDs.
3.10.1
"Battery Detection & Charging" Indicator LEDs
When a battery is inserted into the UCH0053/UCH0054 chargers, amber LEDs labeled "CHARGE 1A, 1B, 2A,
2B" will start flashing which will indicate that batteries are detected in the corresponding location in the
bays. If the battery type is authorized by the charger, charging will commence, and the LEDs will change
from flashing to steady. If the battery type is not authorized by the charger or a fault is detected, the amber
LEDs will cease flashing and the RED LEDs will illuminate, indicating the failure/fault notification.
