NOTE
Information given in this manual references a machine set up for left to right feed
direction. For machines designated right to left feed direction, contact ASM
Customer Support for assistance. Right to left feed machines are not a direct
mirror of the left to right machine the following exceptions relate:
1. In the circuit diagram, later in this chapter, Node 11 becomes Node 16.
2. In the circuit diagram, motor wiring designations are mirrored.
3. The motors are wired in the single direction mode, that is, left to right or right
to left; a machine wired for one direction cannot be wired for the opposite feed
direction.

RAPID TRANSIT CONVEYOR (RTC) MODULE
OVERVIEW
Chapter Issue 4, Aug 14 Technical Reference Manual 22.3
The rapid transit conveyor (RTC) is a programmable width conveyor system
which sets the rail width and transports boards through the machine using belts
and vanes. The system can accommodate up to three boards in the machine
at one time thereby reducing the machine cycle time.
The RTC system consists of three sections:
• Inroad Conveyor
•Print Station
• Outroad Conveyor
Using belts, Board 1 is transported to the end of the inroad conveyor where the
board is stopped by the board stop vane.
The inroad vane is raised and the vane stepper motor drives the inroad vane to
snug the board.
The transport mechanism moves the vanes placing the board in the centre of
the print station.
