3. Locate and fit the ProFlow transfer head unit to the pressure mechanism by

means of the two locating dowels. Slide the unit onto the pressure mecha-

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

4. Lift the light shroud for access (if fitted) and plug the electrical connection

ProFlow Fitted from the ProFlow unit into the socket sited on the right hand

side of the ProFlow on the print carriage, (figure below 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.

Connect the curly pneumatic leads from the pressure mechanism to each

respective left and right pneumatic connector sited either side of the ProFlow

printhead mechanism (figure below refers).

NOTE

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

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

pressure.

5. Connect the pneumatics and switch the machine to ON. To ensure that the

machine recognizes the ProFlow module, the following indications on the

machine MMI are evident:

a. During the boot up sequence the operator is prompted to fit the ‘ProFlow

cover’.

b. The soft key that previously indicated ‘Paste Load’ now indicates

‘Knead Paste’.

(fixed head

machines)

To replace the ProFlow drive belt the printhead mechanism must first be

removed from the print carriage, carry out the following procedure:

1. In Print Carriage Diagnostics, select Drive Carriage to Front Position.

Power down the machine, raise the machine covers.

2. Remove the ProFlow unit if fitted.

3. Disconnect all plugs from the printhead mechanism to the connector panel

on the print carriage.

4. Remove the printhead mechanism by unscrewing the four captive screws

securing the unit to the print carriage.

5. Placing the unit on a secure surface, slacken off the four screws securing

the stepper motor to the support plate, (figure below refers).

6. Remove the old drive belt. Fit new belt in position.

7. 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, (Figure
