Status Indicator RAPs
Initial Issue
024-340 IOT-ESS Communication 1 RAP
BSD-ON:
BSD 3.1 - ESS - MCU Communication
BSD-ON:
BSD 16.1 - ESS
ESS PWB detected a communication failure between IOT and ESS.
Initial Actions
Power Off/On
Procedure
•
Ensure that the customer is programming a job within the parameters of the machine uti-
lizing the UI.
•
Check that connectors on the MCU PWB (
PL 18.2
) and on the ESS PWB (
PL 35.2
) are
securely connected. Disconnect then reconnect the IIT, Control Panel, ESS, MCU all
PWBs connected to them (RAM, Firmware module, EEPROM)
•
Check the sw version of the controller sw. If the problem continues, reload Software (
GP
16
).
•
Replace ESS PWB (
PL 35.2
) (If not fixed by this, reinstall the original ESS & MCU)
•
If the problem persists, replace the MCU PWB (
PL 18.2
)
