041-310 IM Logic Fail RAP
BSD-ON:
BSD 3.1 - ESS-MCU Communication
The IM (Image Management) software control error was detected.
NOTE: When turning the power OFF, turn OFF the power switch first and then the main power
switch.
Procedure
1.
Turn the power OFF and ON.
2.
Install the correct version of the IOT firmware.
3.
Initialize the IOT NVM
(Initialize
NVM). If the problem persists, replace the MCU PWB
18.2).

Fuse 1 on the MCU PWB has blown.
NOTE: Remove the cause of Fuse meltdown before replacing the MCU PWB.
When turning the power OFF, turn OFF the power switch first and then the main power switch.
Chip fuses on the MCU PWB seldom fail because of an internal MCU problem. The cause is
(PL
almost always a short circuit in the wiring or components fed by the fuse. You MUST determine
the source of the short before replacing the MCU PWB.
Procedure
1.
Go to +3.3Volt
2)
for INTLK +24 VDC. Check the ROS Assembly
overvoltage, and then replace the faulty parts or repair the circuits.
2.
Turn the power OFF and replace the MCU PWB
