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 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
