Status Indicator RAPs
Initial Issue
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 (
PL
18.2
).
041-324 MCU PWB F1 Open RAP
BSD-ON:
BSD 1.9 - Power Interlock Switching (2 of 2)
BSD-ON:
BSD 6.9 - ROS Laser Control (2 of 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.
CAUTION
Chip fuses on the MCU PWB seldom fail because of an internal MCU problem. The cause is
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
IOT wirenets
for +3.3 VDC and
BSD 1.9 - Power Interlock Switching (2 of
2)
for INTLK +24 VDC. Check the ROS Assembly (
PL 2.1
) circuit for overcurrent and
overvoltage, and then replace the faulty parts or repair the circuits.
2.
Turn the power OFF and replace the MCU PWB (
PL 18.2
).
