7.3 Power and Charging
l
The operating software monitors battery level and send the AMR to a docking station if
the state of charge is 10% or less. If anything prevents the AMR from recharging and
the state of charge falls to 2% or less, the AMR ceases operation until it can recharge.
l
If one or more individual battery cells becomes over-discharged then autonomous char-
ging cannot start. You must examine the battery to determine whether it can be manu-
ally recharged or is no longer usable. Attempt to balance and charge the battery
manually on a different docking station. If the battery is unrecoverable, you must recycle
and replace it.
NOTE: If the battery temperature exceeds its limits, charging cannot begin. The
software and operator panel will notify you by an information message. See Bat-
tery Operating Environment on page 47.
The docking station supplies enough power for all the AMR's on-board systems, which can
continue to operate during charging. If an AMR is powered off, it powers-on automatically
when you push it manually onto a docking station.
Indicators, Controls, and Connections
The docking station has a power switch and two indicator LEDs:
l
Blue—indicates that power is available.
l
Amber—indicates that a charge is in progress.
The power entry module is located on the dock's right side. An integrated circuit breaker
(thermal fuse in older models) shuts down the dock if it becomes too hot. Wait for the dock to
cool down, turn the switch to off (0) and then back to on (1).
The power plug for AC supply is next to the power switch. Power requirements are 100 - 240
VAC, 50 - 60 Hz, and 8 A.
On the left side of the station (viewed from the front) is a manual charge outlet. Use this to
charge spare batteries.
Environmental Requirements
l
Ambient temperature range:5 to 40°C (41 to 104°F)
l
Humidity:5% to 95% non-condensing
Docking Station Maintenance
!
CAUTION: FLAMMABLEIRRITANT
Follow all appropriate local safety regulations for working with isopropyl alco-
hol, including fire safety, toxicity, and protective clothing and gear require-
ments.
CAUTION: SHOCKRISK
To prevent accidental power-on during servicing, disconnect and remove the
power cable during all docking station service operations. Store the power
cable remotely from the in-service docking station.
