The zero calibration is performed with disabled vacuum and air blast (see Section (9.4.6.1 Zero Calibra-
tion of Vacuum Generator

X Start SITEST.
X Move the gantry so that you can easily reach the nozzle with one and the keyboard with the other
hand.

.
NOTE:
The pressure deviation to the ambient pressure at 0 - mbar (zero calibration) should not exceed
+/-10 mbar.
NOTE:
The value "Vacuum closed" is measured and stored for both Twin modules.
A dialog box shows the old and the new values.
NOTE:
The term "closed vacuum" corresponds to "threshold value closed".

9.4.7 Calibrating the Twin Head
During initial setup or after replacement of a Twin module the Twin Head must be calibrated. This menu
measures the offset between the Twin segment and the PCB camera center.
X Put the nozzles 517 by hand on the segments of the P&P modules.
X Make sure that the first nozzle from the garages are empty and depend on this the filling level from
the nozzle changer are edited, This is necessary for calibration of the pickup height.
X Enter the nozzle "517" for both TWIN modules as active nozzle on the TWIN Head:
SITEST:
X Select

X Select the nozzle changer head function.
X Select the appropriate "segment" from the list.

9.4.8 Mechanical Adjustment of the Z Axis Incremental Encoder
9.4.9 Vision DC/DC Converter
The function of the Vision DC/DC converter is to provide the 42V voltage supply for the stationary
cameras.
The 42V are use for the illumination of the stationary cameras.
When replacing the Vision DC/DC converter, observe the following settings, which depend on your
installation location (main/subdistributor).
9.4.10 Manual Lowering of Z Axis
The Twin head is designed for a placement force of 0.5 to 15 N (up to 30 N for the high force Twin head)
. The rotary axis needs to be very smooth-running, especially for low placement forces. Therefore, the
rotary axis is not constructed for traction forces.
NOTE:
The following calibration steps are performed automatically: - MA zero point, PCB camera,
calibration tool position, head height, TH calibration offset module 1 and 2, IC camera, (option
FC camera), nozzle changer.
NOTE:
The incremental encoder on the Z axis must be adjusted to a distance of 0.4 mm to the
incremental scale. Please adjust the incremental encoder parallel to the incremental scale.
After fitting, check the Z axis track signals (see Section Component Handling).
