8. Fit the appropriate foil-less clamp to the rear rail and secure using the M4

pan head screws.

9. Repeat Step 8 for the front rail.

10. Turn the pneumatic switch Off, located on a magnetic plate on the right hand

side of the machine.

11. Under Setup select Machine.

12. Select Basic Parameters.

13. Set Clamp Type to Board Clamp.

14. This completes the procedure if board clamps have been fitted. If foil-less

clamps have been fitted continue with Step 15.

15. Load a product board.

16. In Diagnostics select Rail System.

17. Select Toggle Board clamp.

18. Using a 2mm Allen key adjust the two downstops on the rear foil-less clamp,

(previous figure refers) to ensure that the top of the foil-less clamp is flush

with the top of the board.

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.
