024-347 IOT-ESS Communication 7 RAP

BSD-ON: BSD 3.1 - ESS - MCU Communication
BSD-ON: BSD 16.1 - ESS
The ESS PWB detected a communication error between the IOT and the ESS.
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 MCU PWB
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
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 MCU PWB
