REPLACEMENT PROCEDURES

17.38 Technical Reference Manual Chapter Issue 3 Oct 06

19. Repeat Step 18 for the front foil-less clamp.

20. Remove the board from the printer.

NOTE

The Board Clamp Setting procedure is not required after snugger to board

clamp/foil-less clamp replacement.

Rear Rail Drive Belt 1. At the rear of the rising table, slacken the adjustable idler pulley by means

of the nut at the front face of the rail drive plate.

2. Slide the adjustable idler pulley to slacken the drive belt.

3. Remove the drive belt and discard.

4. Fit the replacement drive belt.

5. Using a suitable cable tie, engage a forcemeter with the adjustable idler

pulley. Apply a horizontal force of 6kg.

6. Maintaining this force, tighten the adjustable idler pulley securing nut.

7. Using a tension meter on the top of the drive belt, check the tension is

between 38Hz - 45Hz.

8. Adjust the drive belt tension as necessary to achieve the reading in Step 7.

9. In Diagnostics select Rail System module.

10. Select Drive Rail Width Using Two Button Control.

11. Using the left jog button drive the rear rail to the rear for a few seconds, this

evens out the tension in the belt.

12. Repeat Steps 7-8.

13. Select Drive Rail to Board Width.

CALIBRATIONS

Board Transport

Belt Speed

(Auxiliary Rails)

The board transport belt speeds of the two auxiliary rails are controlled by the

M27 and are not adjustable. The belt speed can be measured using a

tachometer on the input or output pulley, check the speed to be approximately

30m/min.

Board Transport Belt Speed (Print Station Rail)

WARNING

LETHAL VOLTAGE. DANGEROUS VOLTAGES EXIST IN THIS EQUIPMENT.

ENSURE ALL ELECTRONIC COVERS AND MAIN MACHINE COVERS ARE

FITTED BEFORE OPERATING THIS EQUIPMENT.

The front and rear board transport belts, of the print station rail, are driven

independently by two variable speed motors. Inevitably one motor drives faster

than the other motor. It is necessary to calibrate these motors so that they drive

at the same speed in either direction. Therefore, the faster motor must be

calibrated to match the slower motors speed.

Each belt motor speed is controlled by a separate speed controller module

situated between the rails on the right hand side of the machine.

The belt speed is measured using a tachometer on the underside of the input

or output pulley and adjusted using the potentiometer on the speed controller

module.

Calibration

Procedure

1. In Diagnostics, select Rail System.

2. Select Belt Speed Calibration, the following window is displayed:

NOTE

Belt speed calibration figures displayed on this page have no relevance to

the belt speeds on this machine.

3. Select either Incr. or Decr. to start the belts.

4. Using a tachometer fitted with the surface speed test wheel, positioned on

the input or output pulley of the print station front belt motor, measure the

speed of the motor right to left.

5. Adjust the motor speed using the potentiometer, situated beneath the white

plastic cover, on the speed controller module to achieve a speed of 59 - 61

metres/min.

6. Repeat Steps 4 and 5 for the rear belt motor.

7. Select Save, the speed of the front and rear belts motors in both directions

are now saved in the machine configuration file.

8. Select Exit.

9. Select Exit.

10. Select Exit.

NOTE

If boards do not butt against the camera board stop during the print sequence,

use the Run on Delay parameter in the Edit Data menu. If the condition persists,

a reduction in the speed of the transport belt motors maybe appropriate.
