How the System Responds to Needle Z Detect or Needle XY Adjust
NOTE: On systems with the optional tip detector, both the Needle XY Adjust and Needle Z Detect buttons are
present. On systems without the optional tip detector, only the Needle XY Adjust button is present.
When you click NEEDLE Z DETECT, the system performs the following actions:
• Moves the dispensing tip over the tip detector sensor and lowers it until it touches the sensor.
• Measures and compares the difference between the last measurement and the current measurement.
• Requests confirmation for any change in the tip-to-workpiece offset (Z clearance).
• Realigns all points in the currently open program to the new tip-to-workpiece offset (Z clearance).
• Automatically performs a Needle XY Adjust sequence (shown below).
When you click NEEDLE XY ADJUST, the system performs the following actions:
• Moves the dispensing tip to a preset location on the workpiece.
• Dispenses a dot of fluid.
• Moves the camera over the deposited dot of fluid.
• Compares the alignment of the dot with the mark image saved in the Mark Library.
• Requests confirmation for any change in the camera-to-tip offset (XY offsets).
• Realigns all points in the currently open program to the new XY offsets.
Changing the Robot Model Selection
The correct robot model must be selected for the system to operate properly. Follow this procedure to change the
robot model selection as needed.

Setting Up Inputs / Outputs
If you connected inputs / outputs, follow this procedure to test input / output connections.
NOTE: All automated dispensing systems provide 8 standard inputs and 8 standard outputs. A kit to expand to
16inputs and 16 outputs is available. Refer to “Accessories” on page89.
PREREQUISITES
The system is properly installed and set up. Refer to “Installation” on page19 and “Setup” on page44.
Input / output wiring is properly connected. Refer to “I/O Port” on page95 for wiring diagrams.

• Click the outputs you want turn ON or OFF, then click the X to close the
window.
NOTES:
• Inputs flash red when they are turned ON.
• Use only inputs / outputs 1 through 8. The remaining I/Os are reserved for the
system.
Configuring Input / Outputs for a Special Purpose
The IO Pin Function feature provides a set of user-configurable conditions that affect the operation of the robot.
Refer to “AppendixG, I/O Pin Function Setup” on page146.

Item Function
Absent Specifies how the system responds when it is unable to recognize a mark.
NOTE: You can assign a specific Absent selection to any saved image in the Mark Library.
Parameter Description
Skip The robot skips to the next program address.
Stop The robot stops.
Pause The robot pauses.
Ask The system asks if you want to: Find Again, Find Next, Stop Find, or use the
Manual mode.
Manual The system asks you to jog the camera to the center of the mark yourself, then to
select CONTINUE to continue the program.
Score Specifies how accurately the camera finds a mark based on a value from 0.1 to 1. A higher value
results in more precise matching. A lower value results in less precise matching.
NOTE: You can assign a specific Score value to any saved image in the Mark Library.
Delay(s) Sets how the long system delays (in seconds) searching for a mark when it reaches the mark area.
Sense Specifies how accurately the camera aligns with the pixels of a mark based on a value from 1 to
200. When the Sense value is low, the camera is slower to align with the mark because it repeatedly
checks the position of the mark to achieve high accuracy. When the Sense value is higher, the
camera aligns with the mark faster, but with less accuracy. For example, a Sense value of 1 means
the deviation cannot be more than one pixel. When the Sense value is 200, the deviation can be up
to 200 pixels.
NOTE: For a slower find speed but better accuracy, enter higher Score and lower Sense values; for
a faster find speed but less accuracy, enter lower Score and higher Sense values.
Circle Size Sets the size of the yellow and green circles on the Camera screen. A higher value results in a
larger circle.
Fast Match If this box is checked, the camera searches for mark more quickly but with less accuracy.
Search
Detail
Sets the area within which the camera searches for a mark. If Search Detail is NOT checked, the
camera looks only within the specified range (set under Range). If Search Detail is checked, the
camera overrides the range settings and performs a full-screen search for the mark. This increases
the chances of finding the mark, but is slower.
Setting How the System Finds Marks (Optional)
Use the fields under CAMERA > SETUP > MATCH to adjust how the system functions when it searches for marks.
