Significance Description
The power status LED indicates the status of the power supply and the
main computer hardware and firmware. Power status, PC
PWR (green)
Normal behavior:
• Off: During a normal startup the LED is off, until the COM Express
module inside the computer unit is started.
• On solid: After completion of startup the LED is steady on.
After start-up phase (30-60 seconds):
• Off: Power input voltage is not in normal range.
Failure during startup (off between blinks). One to four short blinks, one
second off. This is repeated until power off.
• Internal fail of power, FPGA, and/or the COM Express module.
• Replace the computer unit.
Power failure during runtime (fast flashing between blinks). One to five
blinks, 20 fast flashing blinks. This is repeated until power off.
• Temporary voltage drop, cycle the power to the controller.
• Check the power supply voltage to the computer unit.
• Replace the computer unit.
The disk status LED indicates access to the main computer persistent
memory. Disk status, PC
HDD
Normal behavior:
• No color at power on: R34 FPGA is loaded on the main board.
• Yellow: Access (read/write) to internal mass memory.
The computer status LED indicates the startup progress of RobotWare
on the main computer. Computer status,
PC STAT
(red/green)
Normal behavior:
1 Red, solid: Default when turning on the power.
2 Red, flashing: Initial self-test is ongoing and the operating system
is loading.
3 Green, even flashing (~1Hz): The operating system is loaded and
RobotWare is initializing.
4 Green, uneven flashing: The RobotWare system failed to load or
is not installed.
5 Green, solid: The computer is operational and the RobotWare
system is fully loaded.
If the LED does not turn steady green after approximately 5 minutes then
the LED can be used to identify the following issues:
• No color: The internal power initialization failed. Restart the con-
troller. Replace the main computer if the problem remains.
• Red, solid: Internal error. Restart the controller. Replace the main
computer if the problem remains.
• Red, flashing continuously: Failed to load the operating system.
Restart the controller. See
Controller fails to start on page 523 .
Replace the main computer if the problem remains.
• Green, even flashing continuously (~1Hz): Failure during start up.
Check error messages on FlexPendant. See
Controller fails to
start on page 523 .
• Green, uneven flashing: RobotWare Installation Utilities mode.
Troubleshooting procedure
Note Action
See LEDs on page 547 . If the LEDs do not turn steady after
approximately 5 minutes then re-
start the controller and check the
LEDs again. 1
