6.2.6 Calibrating the TwinHead
During initial setup or after replacement of a Twin module the TwinHead must be recalibrated. This
menu measures the offset between the TWIN segment and the PCB camera center.
► Put the nozzles 517 by hand on the segments of the Twin modules.
► Make sure that the First garage is empty and that the filling level for the nozzle changer has
been edited accordingly. This is necessary for calibration of the pickup height.
► Enter nozzle "517" as active nozzle on the TwinHead for both nozzles:
► Start the SITEST program .
► Select the button.
► Select the button.
► Select the required Segment (Twin module) from the list.
► Select Edit.
► Mark the nozzle 517 and select the Accept button.
► Enable Selected segment.
► Select Confirm exchange.
► Select All heads and cameras in the main SITEST menu.
► Only select the checkbox TwinHead of the applicable placement area.
► Choose Start.
NOTICE
The following calibration steps are performed automatically:
► MA zero point
► PCB camera
► Calibrating the calibration tool position
► Head height
► TH offset segment 1 and 2
► IC camera (option FC camera)
► Nozzle changer
6.2.6.1 Mechanical adjustment of the Z axis read unit
