Rail Lifted Sensors The left and right rail lifted sensors are background suppression diffuse type
opto sensors.
These sensors are fitted to the bottom of the left and right moving rail support
arms of the print station rail. The sensor vanes are fitted to the entire length of
the rail stop bars. These sensors feed directly into NextMove card of the
machine PC.
The purpose of the rail lifted sensors is to detect premature lifting of the rail as
the rising table rises. This may occur if tooling or any other object was placed
under the rear rail. They are checked:
1. Immediately after the rail has moved to its new board width following
product file change.
2. When Run is pressed, before the camera moves to board stop position.
3. After printing to check that the rail is fully down before the next print cycle
can commence.
4. When the table moves to rail lift check height before moving to vision height.

Rail Home Sensor The rail home sensor is a through beam opto type sensor.
The rail home sensor feeds directly to the Multiplexer controller and is used to
set the datum position for the moving rear rail. From this datum position, the
moving rail stepper motor moves the rear rail the amount of steps needed to
obtain the rail width set in the current board file. During machine initialization,
(power-up or upon exiting diagnostics), the rear rail moves to the rear of the
machine until the rail opto vane enters the rail home sensor, the motor is driven
in the opposite direction until the vane clears the home sensor and the motor
stops, the rear rail is now at the home position.
NOTE
Homing Sequence of this chapter refers.

Board at Left/Right
Sensors
The board at left and board at right sensors are background suppression opto type
sensors.
These two sensors are used to detect a board at the input and output of the print
station rail. As the machine is bi-directional the functions of both sensors are
reversed when the pass through direction is changed.
The input sensor is used to check for the presence of a board when upline transfer
starts. The board is transported to its position and processed after which it is
transferred to the output sensor where it stops unless the downline conveyor is
free to receive it.
These optos are fitted with a yellow LED along with a sensitivity control. There
is a small amount of positional adjustment in the bracket but generally it is not
necessary to reset it.
NOTE
For sensor sensitivity adjustment refer to Adjustment and Settings section of this
chapter.
