Hello, this is from documentation : ''The mainboard failed to make contact with the NMPS (“New Maintenance Pump System”) –board.
Possible causes:
• The LVDS-cable is not properly connected to the NMPS-board Verify LVDS cable and
connections
• Incorrect firmware version in the NMPS-board. Firmware MUST always match with all
boards Initiate a firmware-update of the slave-boards by starting up the machine + Cancel
+ Enter.
• Verify if there is no error LED indication on the NMPS-board
• Verify if the ALIVE LED on the NMPS-board is flickering If not, verify power supply and
replace when necessary
• Verify if the CAN-LED’s are not burning continuously This can indicate a communication
problem or a malfunctioning CAN bus malfunction.
Always check:
• If all RJ45 cable connections on all the slave-boards are properly connected
• If after all those above described actions, the same problem still occurs, replace the
mainboard."'
