RISK OF ELECTROCUTION, ELECTRIC ARC, OR BURNS
Do not execute any commands from the FDM121 display before returning the IMU to nominal operating
mode when the FDM121 display is flashing.
Failure to follow these instructions will result in death or serious injury.
|
Flashing of the FDM121 display indicates that the IMU is operating in degraded mode. It may be an architecture problem. For more information, refer to the provided in the section DOCA0093•• ULP (Universal Logic Plug) System - User Guide.
If the IMU operating in degraded mode includes an FDM121 display with firmware version earlier than 2.1.3, there is a risk of controlling a device other than the one intended.
