Description
The status indicator LED can be used to
identify the following status during star-
tup/power on:
• Red, steady: Default when power is
available.
• Red, flashing (~1Hz): Power is on, self-
test is ongoing, operating system is
loading.
• Green, flashing (~1Hz): Application is
loaded and waiting for communication.

used to identify the following issues:
• No color: Power to the drive unit is

• Red, steady: Internal error.
• Red, flashing (~1Hz): Firmware error
or self-test failure.
• Green, flashing (~1Hz): Communica-
tion error to another module.
