31 Latched Output ON OFF Pass Output Inspect Idle Sensors Status Pass Fail Pass Fail

32 Strobe If Exposure Time is < 1 ms Configure Strobe Tab to “On” (Default)

33 SETUP – Position, Focus and Adjust Lighting to Create Reference Image Steps For Creating an Inspection TEACH Automatically Configure Values for Good Parts (optional) RUN The Inspection Add To: – Find the Part – Location Tool (rarely used) – Analyze the Part – Geometric Count Tool – Measure the Part – Measure Tool – Set / Criteria Test Tool (required) TOOLS

34 Setup Screen

35 Focus Tab Get an Image Trigger Type Focus Image Brightness Resolution

36 Continuous – The PresencePLUS Pro Software will Trigger the Camera to Snap Pictures as Fast as Possible External – The Camera Waits for an Electrical Signal from the Trigger Input to Snap a Picture Manual – The Camera Waits for the Manual Button on the Software to be Clicked to Snap a Picture Off – The Camera will Not Acquire Images Get an Image – Trigger

37 Focus Get an Image The Focus Number Represents the Image’s Contrast Level –High Contrast – Higher Focus Number –Low Contrast – Lower Focus Number Turn the Lens Focus Adjustment Ring as the Focus Number Increases; Turn the Ring the other Direction when the Focus Number Starts to Decrease

38 Get an Image – Image Intensity Exposure Time (electronic shutter) –The Amount of Time the CCD Image Chip is Exposed to Light –.01 ms to ms Gain – Electronically Boosting the Light (and the Noise) Sensed by the CMOS Imager Use Auto Exposure; Tweak, if Necessary

39 Get an Image – Exposure Time Determines the Amount of Light Needed for an Inspection Determines How Fast a Part can Move Past the Camera While an Image is Being Captured For Moving Targets Minimize Exposure Time by Opening the Aperture and Increasing the Gain For Indexed Targets Leave the Gain at 20 and Adjust Exposure for the Light Needed for Adequate Contrast

40 2 ms 5 ms 10 ms Affecting Blur 1 ms

41 Blur Calculation Example Pixel Blur = 640 Pixels X Exp. (ms) X speed (in/sec) FOV (in) X 1000 (ms/in) Part is 4 inches wide and is moving at 40 in/sec (200 ft/min). The exposure time is 1 ms. = 6.4 Pixels At 1 ms There is a 6 Pixel Blur! Pixel Blur = 640 Pixels X 1 (ms) X 40 (in/sec) 4 (in) X 1000 (ms/in)

42 Maximum Exposure Time (ms) = FOV (inches) X 1000 (ms/sec) 640 Pixels X Speed (inches/sec) Part is Moving at 200 Ft/Min and is 4 Inches Wide Maximum Exposure Time (ms) = 4 (inches) X 1000 (ms/sec) 640 Pixels X 40 (inches/sec) =.16 ms Exposure Time Calculation

43 Tools Screen Tool Overview

44 Location Tools Not Required for Typical P4 GEO Inspection –Useful for Positioning ROI When Using Remote Teach Function –Locate Combined with a Smaller Geometric Count Search Area will Speed Inspection Time Compensates for Translational and Rotational Movement of the Inspection Target Used to Move Regions of Interest (ROIs) that Follow the Location Tool Two Types –Geometric Find –Locate

45 Vision Tool – Geometric Count The Geometric Count Tool Searches For Matching Patterns Workhorse of the P4 GEO Sensor

46 Measure Tool Measure Tool is Used to Measure the Distance Between the Center of Patterns, Edges Found with the Locate Tool or the Sensor’s Origin The Absolute Distance as well as the Horizontal (x) or Vertical (y) Distance in Pixels is Found

47 Test Tools Evaluates Results of Selected Vision and Analysis Tools Activates Outputs Determines Tolerances for when an Inspection Passes or Fails Performs Logical Operations At Least 1 Test Tool is Required for an Inspection

48 Communications Use the Test Tool to Configure Discrete Outputs (Black, Red, White and Light Blue Wires) Use the Communications Tool to Send any Inspection Information out the Ethernet Port and/or the RS232 Serial Port

49 Geometric Count Tool

50 Geometric Count Tool – ROI Selection Chose a Rectangular, Elliptical or Circular ROI
