Gear Belt Replacement

Procedure:

1. Power down the machine. Execute your site's Lockout/Tagout

procedure.

The machine must be powered down and your site's Lockout/Tagout

procedure executed during this procedure to ensure personal safety.

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.

End of procedure.

X-Y Axes Encoder Adjustments

Purpose:

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 Adjustment:

Rotary Disk Alignment

Special Tools:

Set Up Template (46367805)

Set up tool

(43806307 for jumper wire and large head tooling)

(43806311 for standard, 5mm and 5.5mm tooling)

(43806312 for 5mm s/l tooling)

Span Adjustment head (47088701)

Head Drive Shaft (47084401)

Adjustment Procedure:

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 from the end of the X-frame casting to the end of

the limit switch actuator.

Y-axis: 1/4 inch 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.

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.
