Docking Target.
Power Supply Box
The Power Supply Box has LED indicators to display the status of the unit as described below. A Serv-
ice button is also present for use when connecting a fully depleted battery.
The Power Supply Box has a Main Disconnect Switch that turns the unit ON or OFF. When the Main
Disconnect Switch is placed in the vertical position (ON position), the unit powers ON and illuminates
all LEDs on the front panel of the Power Supply Box for 2 seconds. The Power Supply Box is opera-
tional at this moment. Use the LEDs determine the operational status of the Power Supply Box. Plac-
ing the Main Disconnect Switch in the horizontal position (OFF position) will remove power from the
Power Supply Box.
The Power Supply Box performs several diagnostic tests. If a problem is detected, the Power Supply
Box enters a safe state in which all charging power turned OFF and the red LED flashes. Refer to
5-4-2 Battery Charging Problems on page 5-6 for more information.
The Power Supply Box will not automatically charge a battery if it is absolutely depleted.
Pressing the Service button on the Power Supply Box during a charging session will interrupt charg-
ing. Disconnect the battery and then reconnect to resume charging.
