nism. Once the unit is slid fully home, it is secured by closing the locking clip.

6. Connect both curly air lines to the self-seal pneumatic connectors situated

either side of the ProFlow printhead mechanism, figure in Step 2 refers.

7. Connect the ProFlow Paste Level connector (9PL62) to the amplifier con-

nector 9PL61, left hand side, figure in Step 2 refers.

CAUTION

ELECTRICAL CONNECTION.

This electrical connection informs the

machine of ProFlow fitment and must always be connected whilst the

ProFlow unit is fitted otherwise damage may occur if machine is run.

NOTE

If the squeegee paste dispenser is fitted to the print carriage, before using

ProFlow, ensure that the paste dispenser regulator gauge reads '0' pres-

sure.

8. Switch the mains isolator to ON and ensure that the machine recognizes the

ProFlow module fit by displaying ProFlow Uninitialised during the machine

initialisation sequence.

9. Carry out the ProFlow Contact Position Setup in the Calibrations section

later in this chapter.

13. Remove the old belt and fit the new belt in position.

14. Using a cable tie wrap or similar, provide a loop around the top of the motor

body enabling the motor to be pulled using a force meter. Ensure that the

force meter is pulled in the direction which the drive belt is fitted.

15. Pull the force meter until a tension of 3kgs to 4kgs is monitored on the

meter. Tighten the four screws whilst the motor is under tension.

16. On completion re-fit the printhead mechanism to the print carriage and re-
