INTRODUCTION This product manual provides information about installation, use and maintenance of SCU5 controller. The controller includes an operator interface that is used for both measurement and control applications within converting lines. For installation of the sensor and web guide please refer to the respective product manuals.
Sensor and Web Guide Controller Specification The general specifications of the SCU5 controller are listed below. Depending on the application one of more of the output options would be available.
Fig. 2: SCU5 M Controller Physical Dimensions (All dimensions are in mm); Subject to change without notice. The SCU5 M controller has the following ports for connections to the sensor, motor driver and other devices.

Power Input (Port 1) The SCU5 M operates under 24 VDC (± 5%) power with a maximum current requirement of 5 Amps. The power is supplied through a Switchcraft DC power connector. WARNING: Supplying more than 24 VDC would damage the controller permanently.
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.
Analog Output (Port 2) The SCU5 controller without the motor suffix will include a 3-pin Male M8 connector for analog output. The pinouts for the connector are shown below. Color Signal Brown Voltage Blue Current Black Ground/Common The outputs can be chosen via the touchscreen interface to any of the following available output options:...
Opto-Isolated Output (Port 3) For some applications two opto-isolated outputs are available from the SCU5 controller. These outputs are available on a 4-pin M12 female pin connector. A standard M12 4-pin A coded male connector or a pre-wired M12 cable can be used for the connection. The pin functions for the connector are shown in the table below.
Be aware of all national, state, and local requirements for accident prevention and environmental protection. Proper Use The SCU5 M controller is intended for indoor use only for use in industrial and lab equipment that process materials in web form as they move through a converting or raw material manufacturing process. Improper Use ●...
The web guiding operations are accomplished using the web guide operation buttons on the bottom of the screen. The capacitive touchscreen on the SCU5 controller uses a language independent icon based screen that allows ease of operation. Never use sharp or pointed tools of any kind to operate the interface. Best practice is to have operators use their fingers to press the different icons.
When the controller is in servo centering mode, the actuator connected to the SCU5 controller will move towards the home position or center position which is provided by the servo center sensor, typically an inductive proximity switch.

SCU5 controller and Roll-2-Roll Driver. WARNING: If the actuator connected to the SCU5 moves but the actuator position bar does not indicate any movement (either completely black or red), this might be due to corrupted electronic position of the actuator in the memory.
Advanced Settings Menu The SCU5 controller provides advanced settings both for the operator and the maintenance personnel. The advanced settings screen will allow operators, power users and maintenance technicians to adjust parameters to suit their measurement and web guiding needs. This screen can be accessed by pressing the Advanced Settings icon on the home screen.
When the measured web width is more than the nominal web width then the width error is positive. With an appropriate output on the SCU5 controller a fault signal can be generated when the positive width error is more than the upper limit. If the error is equal to the upper limit, no fault signal would be generated.
WARNING: Changes to these settings can have a significant effect for both sensing and guiding applications. Wrong settings can cause damage to the actuator, web guide or devices connected to the SCU5 controller. Hence only those well versed in the operation of the web guiding system or the measurement/sensing system should change these settings.
Controller Setting When the SCU5 controller is used for web guiding purposes the controller settings such as gain, deadband, etc.can be set from this screen. Gain The gain setting needs to be changed based on the actuator lead screw and the mechanical advantage of the web guide structure.
DHCP If the DHCP is set to ON the SCU5 controller (client device) will get the IP address from a network server or a router. The IP address, and other network parameters, would be assigned dynamically and may change after a power cycle if the server or router initiates the change.
NOTE: The DHCP can also be set using the IPConfig utility or other network software directly through the network. This setting would enable or disable the FTP server on the SCU5 controller. This is an advanced feature and should not be changed without consulting with the factory.
Module Type The type of the industrial ethernet module in the SCU5 controller will be printed over the network LED. The available fieldbus options are EtherNet/IP, PROFINET, EtherCAT and Modbus/TCP. If no module is available on the SCU5 controller then the module type would be None.
Sensor 1 /Sensor 2 Web Width When the SCU5 controller is set to provide the width, these registers provide the width output from the controller. Registers 14 and 15 are combined to provide a 32-bit value. The most significant 16-bits are provided in register 14 and the least significant 16-bits are provided in register 15.

Note: If the filter is enabled the output provided would be the filtered output. When the SCU5 controller is not set to provide width, then the registers provide the mean widths of the webs seen by each sensor. Register 14 will provide the mean width of the webs seen by sensor 1 and register 15 will provide the mean width of the webs seen by sensor 2.
WARNING: Web Guiding System enabled by SCU5 controller is an automatic control device that may stop and start at any time without notice, especially when controlled remotely. Hence standard safeguards must be in place to prevent any kind of injury.
Please refer to the respective sensor and web guide manual for proper installation of the web guiding system. The following section describes the steps and conditions required for automatic operation with a SCU5 M web guide controller.
