Figure 2-21. Battery Lift Points
IMPORTANT:
The battery weights 68 kg. There must be at least 3 persons lifting
the battery. For rolling the battery around, one person is sufficient.
Operating the AMR at high ambient temperatures (particularly when carrying a full payload
at high speeds) can cause the battery to exceed its operating temperature limits. If this hap-
pens, do not try to access the battery. You must allow several hours for an overheated battery
to cool sufficiently before trying to remove/replace it.
Battery Maintenance
Every six months:
l
Inspect the battery for damage or leaks.
l
Connect the battery to a charger and allow to fully balance (battery indicator shows all
solid blue LEDs when the state of charge is ≥ 80%).
2.17 Charging Station
The HD-1500charging station consists of two main parts; the power supply box, and the dock-
ing target which the AMR drives itself into. The charging station provides both manual and
automated methods of recharging the AMR's battery.
The power supply box outputs a maximum of 6.84 kW of power, and can charge a fully
depleted battery pack in 40 minutes.

WARNING:
FIRE RISK, ELECTRICAL BURN RISK
The HD-1500 battery, and the charger outputs have high current. You must
take appropriate precautions to avoid potential short circuit.
WARNING:
ELECTRICAL SHOCK RISK
The charging station transfers high electric power, and contains hazardous
voltage. The user must take necessary precautions when working near the char-
ging station, and follow appropriate Lock-Out, Tag-Out (LOTO) instructions
prior to any maintenance work done on the charging station.
Due to high power transfer, OMRON has taken several safety measures to keep the users safe:
o
The electrician access box has a main disconnect switch, as displayed in Figure 1-1.
When the user turns the main disconnect switch ON, the access door locks auto-
matically, and prevents access to the interior of the electrician access box. This is to
block access to the hazardous electrical circuits in the electrician access box.
o
The main electrical compartment door can only be accessed with a key; this prevents
unauthorized access to the main electrical compartment.
o
When the HD-1500 engages with the charging paddle, the docking target performs a
voltage check. It verifies that the HD-1500 is present before it begins charging the HD-
