3110012 - C-board

3110012 – C-board control board (C-Board) – Zünd PN / LC cutting tables

The C board (C-board, 3110012) is fitted to Zünd cutting tables. It ensures the electronic control of a sub-system and passes the signals to the main board.

The Zünd parts catalogue designates it "C-board" for the PN and LC series ("PN/LC-series"). According to the Zünd PN user manual, it processes the signal from the X-axis zero mark sensor and passes it to the master board ("master board"); the Zünd catalogue also lists a "Flat cable C-board - foil sensor" ribbon cable connecting it to the foil sensor ("foil sensor").

• On error "0317", the Zünd PN manual gives three causes: faulty X zero mark sensor (permanent light), C-board fault, or broken link between the C-board and the master board. Check the sensor and the link before replacing the board.
• The "Flat cable C-board - foil sensor" ribbon cable has a length specific to each table size (900 mm on PN-800 according to the Zünd catalogue): check it when replacing the board.

Function

• Processes the signal from the X-axis zero mark sensor (according to the Zünd PN user manual, error "0317")
• Receives the foil sensor ("foil sensor") via the "Flat cable C-board - foil sensor" ribbon cable (Zünd parts catalogue)
• Communicates with the master board ("master board") of the PN/LC series
• Ensures the electronic control of a sub-system
• Passes the signals to the main board
• Acts as an interface between the firmware and the hardware

Signs of wear

• Error code "0317" "AC zero mark X": X zero mark sensor seen as permanent light, possible C-board fault or broken link with the master board
• Sub-system not driven
• Electronic errors
• Loss of internal communication
• Erratic behaviour or machine stops

Replacing this part restores the machine to proper working order.
