TheGC 300 provides accuracy towithin ±0.004 inches (0,01mm)of edge or centerline positions.The GC 300 receives signalsfrom web position sensors andtranslates them into controlsignals for web position drivemotors. The system maintainsconstant position of paper, film,foil, textiles, non-wovenmaterials, metal strip, rubber orany product processed in acontinuous strip.The GC 300 can take signalsfrom either pulsed LED sensors912696 Automatic Centering Proximity Sensor912736 Second Sensor Boardfor opaque edge monitoring, orultrasonic sensors for monitoringopaque and transparentmaterials. A special sensor isalso available for followingprinted lines or pattern edgeson previously printed webs.This is the Line Follower Sensor.A single sensor can be used forEdge Position Control (EPC).With an optional daughter boardand a second sensor, the GC 300can provide Center PositionControl (CPC). The sensor shouldbe mounted with it’s measuringcenter aligned with the desiredposition of the web edge.CPC requires two sensorsplaced opposite one another oneither side of the web. Thisconfiguration assures that thecenter of material beingprocessed stays aligned withthe center of the machine.Standard Features• Smart Current Limitingprotects motors.• Automatic Calibrationsimplifies setup.• Universal Symbology forinternational applications.• Use either Proximity or Reedauto-center sensors forflexible installation andeasy set-up.• Internal thermal protectionprevents overheating.• CE marking—usable inEuropean community.Three easy to useOperating Modes forflexibility.Nexen’s straight forwardtouch pad controls simplifyadjustments and changes inoperating mode.AutomaticActuator is constantly driven toreduce web position error tozero. Following setup andcalibration this modeautomatically keeps the webpositioned correctly.ManualThis mode allows you to steerthe guide mechanism left orright during setup or whenmanual override is necessary.Auto-centeringUsing either reed switches orproximity sensors, this modeautomatically centers the rollstand or guide roll assembly formachine setup, calibration or asa system “standby.”320
