7.5.4 Setting the Jaws for C&P20A
7.5.4.1 Basics
The jaws need to be correctly set, to ensure that the bridge between the raceway and jaws is accurate.
The correct height between the raceway and jaws is achieved by determining the zero point correction
value for the Z axis.
When fitting the jaws at the Z axis, it is possible to rotate the jaws. With the help of the setting gauge,
the correct angle of the jaws to the raceway can be fixed.
When could you need to set the jaws?
When error messages are issued by the station software (e.g. reference run).
If the determination of the Z and star zero point correction is not successful, you will need to have
the position of the jaws checked by the Siemens Service team.
When replacing or dismantling the Z drive unit, as the jaws are not aligned to the raceway.
When dismantling the component sensor and star carrier
NOTE:
This service task requires the use of a special tool and may therefore only be performed by
specially trained service technicians from SIEMENS. The procedure is described in a separate
manual.

7.6 Nozzle changer
The nozzle changer enables the nozzle configuration to be changed quickly, thus allowing the placement
head to be quickly adapted to the needs of the placement process.
7.6.1 Nozzle Changer for C&P20A
7-47: Main view - nozzle changer and nozzle magazine C&P20A
Legend
The new nozzle changer carrier can be used for both the C&P20A and the CPP heads, with the
corresponding magazines. Therefore, the nozzle changer does not need to be exchanged for the head
modularity between the C&P20A and CPP head.
The nozzle changer consists of six magazines, each with twelve nozzle garages. Each nozzle garage
can be configured with different nozzle types. Each magazine is clamped on the basic nozzle changer
body with 4 push buttons and two centering pins. The nozzle magazines are opened or closed with the
help of the pneumatic valves. Each magazine can be individually released and removed by pressing the
lever (one on each magazine). There are three microswitches beneath each magazine. These monitor
the correct position and correct magazine type. If all magazines have correctly engaged on the basic
body, this will be shown by a green LED. Since this microswitch is integrated into the safety circuit, the
machine can not be started unless the magazines are installed.

7-48: Nozzle changer for X machine
Legend
In X series machines, a maximum of twelve nozzle changers are possible for each location,
depending on the machine configuration.
The nozzle changer for the X machines has been extended to include the following functions:
– Magazine ID
– Height query
The nozzle changer carrier can accommodate the various magazine types for the C&P20A and CPP
heads.
The machine recognizes the configured magazines via the magazine query (microswitch).
If the wrong magazines are configured for the head, a warning will be issued to prevent a head crash.
– 10xx magazine: Switch 2 (center) pressed
– 20xx magazine: Switches 1 and 3 pressed
– 28xx magazine: Switches 1, 2 and 3 pressed
7.6.3 Nozzle Stations
Different nozzle stations need to be used for the X series machines with X4i. These differ only in the
mechanical construction. For X2, X3 and X4 machines, you need to use the universal nozzle station and
for the X4I the narrower version, for the respective placement head type.
