FAILURE
Description Communication failure between the ESS and IOT.
BSD on : CH3.1A CH3.6A
Procedure
Perform re-installation of the software (latest version).
Check the connection status of the MCU PWB and ESS PWB
connectors. If no problems are found, replace the MCU PWB
(PL13.1). If the problem persists, replace the ESS
PWB.(PL13.1)

Description It is time to replace the IBT BELT CLEANER.
BSD on : CH9.31A
Procedure
If the problem persists after replacing the CLEANER ASSY,
replace the MCU PWB.(PL13.1)
If the problem persists after replacing the MCU PWB, replace
the MCU MF NVM PWB.(PL13.1)
004-415 2nd BTR UNIT CHANGE SOON
Description It is time to replace the 2nd BTR UNIT.
BSD on : CH9.31A
Procedure
If the problem persists after replacing the 2nd BTR UNIT,
replace the MCU PWB.(PL13.1)
If the problem persists after replacing the MCU PWB, replace
the MCU MF NVM PWB.(PL13.1)
004-417 IBT BELT UNIT (1st BTR) CHANGE SOON
Description It is time to replace the IBT BELT UNIT.
BSD on : CH9.31A
Procedure
If the problem persists after replacing the IBT BELT UNIT,
replace the MCU PWB.(PL13.1)
If the problem persists after replacing the MCU PWB, replace
the MCU MF NVM PWB.(PL13.1)
004-420 IBT BELT UNIT (1st BTR) LIFE END
Description The life of the IBT BELT UNIT ended.
BSD on : CH9.31A
Procedure
If the problem persists after replacing the IBT BELT UNIT,
replace the MCU PWB.(PL13.1)
If the problem persists after replacing the MCU PWB, replace
the MCU MF NVM PWB.(PL13.1)
004-421 IBT BELT CLEANER ASSY LIFE END
Description The life of the IBT BELT CLEANER ASSY
ended.
BSD on : CH9.31A
Procedure
If the problem persists after replacing the IBT BELT
CLEANER ASSY, replace the MCU PWB.(PL13.1)
If the problem persists after replacing the MCU PWB, replace
the MCU MF NVM PWB.(PL13.1)

004-605 IOT NVM EMPTY
Description The system detected that the NVM of the IOT is
empty.
BSD on : CH3.1A CH3.6A
Procedure
If the problem persists after turning the power On/Off, replace
the MCU PWB.(PL13.1)
If the problem persists after replacing the MCU PWB, replace
the MCU MF NVM PWB.(PL13.1)
004-640 BELT WALK FAILURE
Description IBT BELT EDGE adjustment failure
BSD on : CH9.19 CH9.31A
Procedure
Is the Actuator of the Edge Sensor touching the BELT?
Y N
Check the installation status of the Actuator.
Turn On the power.
Run DC330 [004-014].
Is +3 VDC to +1 VDC measured between the I/F PWB J533-
A11 (+) and GND (-)?
Y N
Is +5 VDC measured between the I/F PWB J533-A9 (+)
and J533-A10 (-)?
Y N
Check the +5 VDC circuit to the I/F PWB J533-A9.
Is +5 VDC measured between the I/F PWB J533-A11 (+)
and GND (-)?
Y N
