I/O Node Boards
CAUTION
ANTI-STATIC HANDLING. STANDARD PRECAUTIONS MUST BE ADHERED TO
WHEN HANDLING ELECTRONIC CARDS AND CONFIGURING AND INSERTING
INTO THE ENCLOSURES.
The I/O Node Boards consists of multiple inputs and outputs, CAN encoder/
decoder and multi-way connectors for machine components.
There are three I/O Node Boards fitted to a standard machine with a possible
one other board for the underscreen cleaner, if fitted, these are:
• I/O Node 1 - NextMove ES card (CAN master) located in the M36 Machine
Control Enclosure (standard)
• I/O Node 2 - Main Machine I/O board located at the rear of the machine
(standard)
• I/O Node 3 - Print Carriage I/O board located inside the print carriage
extrusion (standard)
• I/O Node 4 - Screen Cleaner I/O board located at the rear of the machine
(optional)
I/O Nodes 2 & 4 have a green (status) and a red (error) LED mounted on the
board. The status LED should flash twice periodically and the error LED should
not be illuminated during normal operation. The following table describes other
operations of the LEDs:
I/O Node 1 I/O Node 1 is the CAN master and is also known as the NextMove ES card
housed in the M36 Machine Control Enclosure. For more information, refer to
the M36 Machine Control Enclosure - NextMove ES Card section of this
chapter.
