NOTE:
If two sensors are connected and configured for edge mode, the controller will automatically
configure the appropriate guiding method based on the orientation of the edges. If both the left and the
right edge is seen by the sensor, the center guiding mode will be enabled. If both the sensors see the same
edge of the web then an average of the sensor measurement will be used to guide the web.
NOTE:
If two sensors are connected and configured for contrast mode, only the sensor that is selected will
be used for guiding.
NOTE:
The sensors can be enabled or disabled electronically within the controller even if they are physically
connected with cables.
NOTE:
If two sensors are connected and configured for edge mode, the analog output can be configured
for left edge, right edge, centerline web position or web width.
NOTE:
If two sensors are connected and configured for contrast mode, the analog output can be configured
for left edge, right edge, centerline web position or web width.
WARNING:
Only the sensors and cables provided by Roll-2-Roll Technologies LLC should be connected to
the sensor ports. Third-party cables and sensors may damage the controller and will void the warranty.
Please consult with the factory before adding any patch cords.
Motor Communication (Port 2)
The SCU5 controller with “M” suffix includes a 4-pin Male M8 connector to connect the controller to a motor
driver (supplied by Roll-2-Roll Technologies LLC) used for web guiding applications. A pre-wired motor
communication cable with the 4-pin M8 female connectors on both ends is used to connect the controller
and the motor driver. The motor communication cable carries the power and the communication signals
between the SCU5 M controller and the motor driver.

WARNING:
Never connect or disconnect the motor communication cable while the SCU5 controller is
powered or connected to a power supply. Always power down the SCU5 controller during the
connection/disconnection of the motor communication cable.
WARNING:
Only the cables provided by Roll-2-Roll Technologies LLC should be connected to the motor
communication port. Third-party cables and sensors may damage the controller and will void the
warranty.
