Fitting the front section of the head
For details, refer to the service manual.
► Insert the two O-rings into the back part of head.
► Carefully insert the distributor into its seat.
► Turn the placement star half a step (C&P6: 30°, C&P12: 15°), fit the front part of the head and screw
tight.
► Reconnect the system to the electrical and compressed air systems.
► Insert cleaned or new sleeves into the segments.
► Insert cleaned or new valve plungers into the valve housing.
Fitting the Placement Head
► Fit the placement head back onto the gantry. Read the service manual for your machine first.
► Switch the placement machine on at the main switch.
► Let the placement head take up the nozzles again.
Test placement:
► The distance between the component camera and the PCB camera can be changed by separating
the front and back parts of the head.
► Carry out a test placement run to test whether the placement accuracy is still guaranteed.
► If the placement accuracy is not guaranteed, calibrate the segment offset 2.
CAUTION
Damage to the O-rings
The O-rings must not be seated on the distributor, otherwise they may be damaged.
► Insert the O-rings into the back part of head.
