Page 4: Introduction
In EPC mode, it is acceptable to connect two different sensors to the GC300. Each sensor is set up independent of the other and connected to be either the left or right sensor. In EPC mode, only one sensor at a time can be used to sense web position. -
Page 5: Installation
INSTALLATION NOTE: The GC300 is an electronic component and should be mounted in a shock, vibration, and moisture free area, which has an ambient temperature greater than 32°F [0°C] and less than 122°F [50°C]. Excessive temperatures will cause the GC300 to stop normal function and give an error signal (See TROUBLESHOOTING). -

ELECTRICAL CONNECTIONS WIRING INSTALLATION GUIDELINES This product is designed to minimize the effects of ElectroMagnetic Interference (EMI) on its operation, but as with any electronic device, proper installation and wiring methods are necessary to ensure proper operation. By doing so, the interference from external effects such as electrical line spikes, electrical noise, static electricity, etc. will be minimized. -
Page 8: Sensors
An AC power disconnect must be wired externally as there is no power ON/OFF switch on the GC300. Prior to connecting any wires, selecting internal switch settings or opening the controller cover be sure the AC power is turned off and locked and proper warning notices are applied according to safety regulations. -

NOTE: If the web guide does not have end of travel limit switches for its actuator, connect the following terminals together: J2-3 to J2-4 and J2-5 to J2-6 in order for the GC300 to operate normally (See Figure 14). Terminals J2-1 and J2-2 provide the power to drive the Linear Actuator (See Figure 14). -
Page 12: Front Panel Description
SENSOR KEY The GC300 is in EPC mode when only one indicator is lit and is in CPC mode when both the left and right sensor indicators Repeatedly pressing this key enables the user to select the are lit at the same time. -
Page 13: Configuration
CONFIGURATION NOTE: The GC300 checks DIP switch settings only during power up. If any DIP Switch settings are changed, the GC300 must go through a power-up cycle in order to recognize the changes. SW2-1 and SW2-2 indicates the Sensor Type connected at Terminal J8 (See Figure 16). -
Page 14: Power Up, Reset And Factory Reset
At power up, all the indicators on the Control Panel will flash on and off once; then, the GC300 will enter the Auto, Auto- Center, or Manual Mode that it was in prior to the previous shutdown. The GC300 will automatically reload the last settings made to sensor selection, gain, offset, and deadband (See Figure 17). -
Page 15: Operation Modes
Automatic Mode, the GC300 senses the web position signal from the sensors. The edge of the web must be in the center of the sensor zone. If the web moves off center, the GC300 will issue a corrective signal to the linear actuator, which will move the roll stand or guide roll mechanism to bring the web back to center. -
Page 16: Remote Operation
The GC300 will issue an output signal to the Linear Actuator to maintain the Automatic Centering Switch in its center or null position at all times while in the Automatic Centering Mode. NOTE: Refer to your Nexen web guide manual to determine if adjustment is necessary for the Auto Centering Limit Switches or Proximity Sensor. -
Page 17: Sensor Calibration And Alignment
SENSOR Key. The three Setup indicators will light and one Sensor indicator will light, indicating that the Sensor is being calibrated (See Figure 25). Insert the web which the GC300 will guide to block the light path to the sensor; then, completely remove the web (See Figure 26). - Page 18 Arrow NOTE: If the SETUP Key is pressed instead of the ENTER Key, the GC300 will exit the Calibration mode and return to FIGURE 27 the Normal Operation mode without zeroing the Offset or calculating Gain or Deadband (See Figure 25).
-
Page 19: Sensor Alignment
After the web guide moves to the center position, switch the GC300 to Manual Mode and align the web to the desired location inside the Sensor; then, if necessary, apply tension to the web (See Figure 28). -
Page 20: Manual Adjustment - Offset
Gain is changed, no change is stored in the GC300 NOTE: Press and release the - or + key to incrementally change the value setting. Press and hold the - or + key for memory and the GC300 will return to Normal Operation more than one second to ramp the value setting up or down mode (See Figure 30). -
Page 21: Remote Offset Control
NOTE: The Deadband adjustment enables the user to set the amount of position error the GC300 measures before it makes corrections. A larger deadband will require a larger position error before the GC300 corrects it, and vice Deadband versa. Deadband is preset during the Automatic Calibration... -
Page 22: Speed Offset
With this adjustment the faster speed is slowed down to be equal to the slower speed. This allows the GC300 gain setting to be applied uniformly during times when the actuator is extending and retracting and reduce the chance of stability problems. - Page 23 reached or the right limit input is not connected.
