ELECTRICAL DETAIL
Electronics On the left hand side of the machine, behind the print carriage bearing support,
the drive board, and the node board, are mounted on a DIN rail. Power to the
boards is derived from the M37 power enclosure.
Active squeegee drive signals are generated on the drive board.
The node board is used for routing signals from the driver to the switches and
sensors.

Drive Board The drive board and the node board are located together, behind the print
carriage bearing support, on the left-hand-side of the printer. The drive board
generates the signals required to drive the active elements of the squeegees.

Power comes from the M37 power supply enclosure, it supplies the following
voltages: 42V, +24V SW, +24V US and +12V.
Drive signals activate a squeegee via N18PL14. This cable divides to provide
independent drive signals to the front and rear squeegees.
NOTE
I/O Connections are shown in the Machine Control Chapter.
Node Board The node board routes signals from the drive board, or the sensors and
switches, as follows:
Signals routed from the drive board to the node board across JP1:
• Enable and status indicators
Feedback signals from the node board to the drive board across JP1:
• The system is ready to activate the squeegees (enable switch)
• A squeegee has moved from dwell to contact height or vice-versa (front
and rear proximity sensors)
NOTE
I/O Connections are shown in the Machine Control Chapter.
