NOTICE

Aperture ring

Before inserting the aperture ring, make sure that the seal disk [03046345-xx] has been posi-

tioned correctly (orientation) on the aperture ring for the C&P20 A/P [03046344-xx].

When inserting the new aperture ring for the C&P20 A/P, make sure that the pin engages in the

relevant hole on the star carrier. The aperture ring should remain fixed from alone.

► When tightening the screws, carefully take hold of the

star near the segment guidances and hold it on the

star carrier.

► Make sure you do not damage the aperture ring or

nozzles.

► Screw the aperture ring tight using the DIN912-

M3x10 screws. Make sure that it is not distorted.

► On a C&P20 A tighten the screws with a torque of

25 Ncm; on a C&P20 P head, hand-tighten the

screws.

► Check whether the O-ring 42x2 NBR70 has been

properly placed into the groove on the aperture ring.

NOTICE

Restrictions for TwinHead on the gantry to be converted

The TwinHead is not compatible with vacuum pump operation. Do not convert the pneumatic

supply for the gantry affected to vacuum mode. If the compressed air supply for this head is

converted to vacuum operation, the return cylinder will be unable to move out and the Z axis

will remain in its top position.

CAUTION

Conversion from C&P head to TwinHead

If you need to convert a gantry from C&P to TwinHead, you must re-establish the original com-

pressed air supply for this gantry. Conversion reversal must be performed on all assemblies for

this gantry. Partial conversion of the pneumatic unit, for example, involving disconnection of the

gantry hoses (additional vacuum hoses) during compressed air operations, can lead to serious

placement machine malfunctions.

CAUTION

Conversion from TwinHead to C&P head with vacuum operation

If you need to convert a gantry with TwinHead to C&P head with vacuum function, you must

retrofit the vacuum equipment for this gantry. If you operate a C&P head which has been con-

verted for vacuum operation at a gantry with compressed air, this could lead to serious damage

to the placement head if the silicon hoses to the segments should loosen.

CAUTION

Preparatory work

After you have properly shut-down the operating system: turn the machine off at the main

switch and isolate it from the mains, before you perform any work to the machine. In addition,

the compressed air supply must be turned off at the main valve of the compressed air unit, in

the machine base, and the compressed air lines must be bled by actuating the needle valve on

the compressed air unit. See also "1.2 Preparatory Work..." [ ➙ 73].
