Manually Determining the DP Axis Zero Point Correction
Manually Determining the DP Axis Zero Point Correction
NOTICE! Manual determination of the DP zero
point correction value is only required if the automatic
calibration was terminated!
► Enter a value of zero at Zero correction (1) for
the DP axis of the respective segment.
► Select the button (2) to apply the value to the head
EEPROM.
► Select Write head and machine data (3) to
save the value.
► Select Reference head axis (1).
The DP axis is now positioned exactly on the zero pulse
of the incremental encoder.
► Switch over to the menu DP axis --> Common
functionalities. The axis should show the
status Referenced and a position of zero (1).
► Attach the calibration nozzle to the TwinHead
segment.
► Manually turn the DP axis with the calibration nozzle
so this is parallel to the conveyor edge (+/- 5Grad)
and the mark on the calibration nozzle points to the
other segment.
► Switch over to another menu and back to this one.
This refreshes and updates the view.
► Read the value at Position.

Setting the Pr essure Control Valve
Setting the Pressure Control Valve
► Select Zero correction data and enter this
value in the Zero correction field (1) of the
relevant segment.
► Select the button (2) to apply the value to the head
EEPROM.
► Select Write head and machine data (3) to
save the value.
► Perform Reference head axis.
The nozzle should now be parallel to the conveyor edge.
► Perform automatic zero point correction of the DP
axis.
► Select the button shown (1).
► Select Zero pressure adjustment (2). This
switches the machine compressed air off and
measures the ambient pressure at the nozzle. The
pressure control valve is therefore set to the ambient
pressure. This is important when machines which are
installed at high altitudes need to be operated in
relation to sea level.
As a result, you will be issued with a zero point correction
value for the pressure control valve.
This function can be repeated with the
Restart button(1).
The zero point correction value should be 0 +/- 10.

Calibration of the TwinHead and Camera Offsets
The final calibrations that are required after a new TwinHead has been fitted to a machine involve the
calibration of the head and camera offsets.
Calibration Step 1
Calibration Step 1
You need a 518 nozzle for this function.
► Select the button Calibrate vacuum with
closed nozzle (1). The gantry moves over the
fixed conveyor side and moves the Z axis
downwards. When the nozzle touches the conveyor
side, a closed nozzle vacuum will be measured. A
vacuum value in mbar will be shown as a result (2).
This depends on the machine installation site, in
relation to sea level.
1. Select the ‘Service’ menu.
2. Select ‘Single Calibration’ menu.
