Gear Belt Replacement
1. Power down the machine and perform Lockout/Tagout according to
local procedures.
WARNING
The machine must be powered down and the local Lockout/Tagout
procedure performed to ensure personal safety during this procedure.
2. Loosen the screws at the edge of the encoder mounting plate. This
action unloads the springs that apply pressure to the dowel pins.
3. Remove the three mounting screws that secure the motor mounting
bracket to the motor mount and carefully remove the motor and motor
mounting bracket assembly.
4. Loosen the two encoder coupling screws on the ball screw end of the
coupling, but do not remove.
5. Remove the screws on the encoder cover assembly and remove the
cover assembly.
6. Replace the gear belt.
7. Replace the encoder cover assembly, ensuring that the attached
coupling is mated to the ball screw shaft, then tighten the screws in the
encoder cover assembly.
8. Tighten the two screws in the ball screw end of the encoder coupling.
9. Install the motor and motor mounting plate assembly using the three
screws. Leave the screws loose enough to allow the dowel pins to
supply the correct tension.
10. Ensure that the gear belt is correctly seated in both gear belt pulleys by
rotating the pulleys several rotations. This can be done by moving the
appropriate axis by hand.
11. Tighten the screws at the edge of the encoder mounting plate so they
compress the springs which then apply a load to the dowel pins.
Ensure the motor is pushed away from the ball screw when the dowel
pins apply a load to the motor mounting bracket.
12. With the tension applied, again ensure that the gear belt is correctly
seated in both gear belt pulleys by rotating the pulleys several
rotations.
13. Tighten the three screws on the motor mounting bracket.

X-Y Axes Encoder Adjustments
This procedure ensures that the positioning of the X-Y axis encoder settings
correspond with the position of head 1.
If any of the rotary encoders are misaligned, the head 1 position does not
correspond to the pattern program values.
Prerequisite Procedure
Rotary Disk Alignment
(43806312 for 5mm s/l tooling)
Span Adjustment head (47088701)
Head Drive Shaft (47084401)
Set Up Tool
Special Tools:
Set Up Template (46367805)
(43806307 for jumper wire and large head
tooling)
(43806311 for standard, 5mm and 5.5mm
tooling)
1. Push the STOP button.
2. Palm the machine down as detailed in the Operation Manual, then set
the limit switch actuators to the following set up dimensions.
X-axis: 3/4 inch (19,05 mm) from the end of the X-frame casting to
the end of the limit switch actuator.
Y-axis: 1/4 inch (6,35 mm) from the end of the sheet metal actuator
mounting surface to the edge of the limit switch actuator
block.
3. Using the head drive shaft tool, manually position the head tooling on
both insertion heads to the tool safe position to prevent possible
damage to the insertion tooling during positioning system movements.

4. Place the set up template on the rotary table beneath head 1 and secure
it in position using the locator pins and thumb screws.
5. 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.
WARNING
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.
6. After the IM Diagnostics has completed its initialization, select the
following. Diagnostics>Manual Diagnostics
The Manual Diagnostics screen is displayed
7. In the Outputs side of the Manual Diagnostics screen, select the
following. Section>UIMC 1 Axis Outputs
8. Palm the machine up and push the INTLK RESET push button.
9. Select Channel B: Table Y Axis>Zero
The Zero - Table Y Axis dialog screen is displayed.
