LED Color Description
ERR Off no error
Blinking Red battery low - battery low error occurs when the battery
charge is low. The AMR Controller battery is not a user-
replaceable item.
NOTE: The battery lifespan is 10 years.
Solid Red l thermal shut down - the thermal shut down occurs
when the AMR Controller gets too hot.
l power supply input under/over voltage or power sup-
ply defective - power supply errors occur when there
is an issue with the incoming power to the AMR Con-
troller. This error can also occur if the PSU (power
supply unit) board inside the AMR Controller is
broken. Such conditions could be the result of drop-
ping the AMR Controller, or incorrect wiring of the
AMR.
HDD Flashing
Orange
HDD (Hard Disk Drive) LED flashes orange when the disk is
accessed. The flashing is not consistent or timed. It depends
on what the user is doing with the system at that time.
RUN Green active drive under user control (via OS)
MCU Off MCU (Multipoint Control Unit) not active
Blinking MCU active
Solid MCU process hang
IO
ERR
Off no error
Solid I/O error detected
DRV Off no motion commanded
Solid motion being commanded
CAN Off no active link with motor controllers
Solid active link with motor controllers
NOTE: The LEDs in the middle row have the same meaning as the top LEDs.
Ethernet Switches
The HD-1500 has three Ethernet switches (Navigation switch, Obstacle Avoidance switch, and
MQTT switch) located in the electronics bay, as shown in the following figure. The Ethernet
switches allow for communication between the peripherals, lasers, Machine Automation Con-
troller, and AMR Controller. Each Ethernet switch has eight available ports (total of 24 Eth-
ernet ports), which connect to the peripheral devices as well as the main computing modules.
The AMR Controller has five available ports for Ethernet communication, and port No. 5 is
reserved.
