The tooling should be set so the tool can be removed from the formers
and inserted back into the formers and held in position. If the tool does
not fit, perform the Span axis mechanical adjustment.
17. Using the head service wrench, manually lower the insertion head so
the set up tool is just above the set up template.
The center of the set up tool should be no more than 0.5 inches
(12,7mm) away from the holes in the template. If it is more than 0.5
inches, remove the set up tool, adjust the negative limit switch actuator
and return to step 7.
18. In the increment box for both the X and Y axis select 0.001 inch
increments and jog the axes until the set up tool extends into the holes
in the template without deflecting the pins or striking the template.
19. Click on the Disab. button for both the X and Y axes.
20. For each axis, the Axis Location should read 9.0 inches. If the set up
tool does not fit into the template, jog the appropriate axis in .001 inch
increments until it does. At this point, disable the axis, rotate the
encoders until the Axis Location display reads 9.0, 9.0 and the Home
Pulse display appears. Tighten the encoder securing hardware.
21. Manually raise the insertion head to the tool safe position and remove
the set up tool from the outside formers.
22. Repeat step 7 through 12 to zero and position the X and Y axes.
23. Install the set up tool in the outside formers then check the adjustment
by manually lowering the insertion head until the set up tool extends
into the holes in the template.
Ensure set up tool pins do not flex or bend the template as they enter
the holes.
24. Manually raise the insertion tooling then remove the set up tool from
the outside formers and the set up template from the rotary table.
25. Exit out of the IM Diagnostics function.
End of procedure.

X-Y Axes Limit Switch Adjustments
Purpose:
When activated, the X and Y limit switches prevent the tables from being
driven into their mechanical limits. The Y limit switches and X limits
switches are all made by separate actuators.
Prerequisites:
X and Y Axes Encoder Adjustments
Machine palmed down
Adjustment Procedures:
1. Manually position the head tooling on the insertion head to the up
position to prevent damage to the insertion tooling during positioning
system movements.
2. Palm the machine up and push the INTLK RESET push button.
3. Activate the IM Diagnostics as follows. Refer to the IM-UPS and IM
Diagnostics documentation for specific details relating to the operation
of the machine terminal.
Select the IM Diagnostics icon.
When the machine is in the IM Diagnostics function, power is provided to
the machine. Exercise caution when performing the following
procedures to avoid Injury to personnel and equipment.
4. After the IM Diagnostics has completed its initialization, select the
following. Machine Setup>Critical Axis Positions
The following message is displayed.
5. Click on Yes. This zeros all axes.
The Set Up Critical Axis Positions screen is displayed.

6. If the desired axes in the Axes to Display area of the screen are not
selected, refer to the Critical Axes Position section of the IM
Diagnostics document for information on selecting the desired axes.
7. Select the desired axes to be adjusted, then proceed as follows for each
specific limit adjustment.
X Axis Negative Limit
1. In the Table X Axis section, click on the value (-0.125) in the entry
field then select Go To.
2. The X axis will move at a set speed to the negative axis position.
3. Depending on the limit actuator position, one of the following occurs.
a. The limit actuator fails to contact the limit switch. In this case,
move the limit switch actuator until the negative limit just
actuates, then secure the actuator. Zero the axis and select Go
To again to verify the correct limit position.
b. A negative hard limit occurs, the Hard Limit indicator is
displayed. In this case, move the actuator block slightly away
from the limit switch then repeat steps 1 through 3.
4. The value in the display field, at the end of this procedure, should be
between -0.105 and -0.145.
Do not move the negative limit actuator excessively. Excessive
movement will disrupt the zero position of the axis and may require axis
encoder adjustment.
End of procedure.
