7.3 Power and Charging
Indicators, Controls, and Connections
The power supply box has a main disconnect switch which turns the unit on or off. When the
main disconnect switch is placed in the vertical position (ON position) the unit powers on,
and performs a lamp that illuminates all LEDs on the front panel of the power supply box for
1.5s. The LEDs then enter their operations state, displaying the status of the power supply box.
The power supply box then becomes operational.
The power supply box performs several internal self-tests. If any of these fail, the power supply
box enters a safe state where all outputs are turned off and the Red LED illuminates. The only
way to clear faults like this is to power off the power supply box.
A push button on the side of the power supply box is provided for charging a battery that has
been completely depleted. A battery in this condition can only be charged by direct connection
to the power supply box, outside of an AMR. The power supply box will not automatically
charge a battery in this state; after connecting the completely depleted battery to the power sup-
ply box you must momentarily press the power supply box’s push button to allow charging to
begin. For information on how to charge the battery outside of an AMR, see: Charging a Stan-
dalone Battery on page 192.
NOTE: If the push button is depressed and held in place by tape (or by other
means), the system will not recognize this as a confirmation for dead battery.
The following table provides description of each LED:
LED color Description
Blue Power On AC power on
Off AC power off
Green Operation state On Normal operation
Off Not in normal oper-
ation
Blinking Debug active
Yellow Charging state On Charging
Off Not charging
Blinking Needs operator atten-
tion
When the yellow LED light is blinking, you must press the push button to confirm that you
have connected the battery manually.
IMPORTANT: Do not press the push button if the yellow LED light is blinking
and there is no battery connected.
NOTE: If the user connects a live battery to the charging station, manually, the
yellow LED light will not blink. The system itself will confirm that a battery has
been connected.
When the yellow LED light is solid (charging the battery manually or autonomously), pressing
the push button will halt the charging, and the yellow LED light will turn off. To resume char-
