PLEASE NOTE 11
The conveyor setpoint width relates to both conveyor belts. When the command is received, the
conveyor belts are set to the setpoint width one after another.

11.3.8 Maintenance
The individual conveyor belts and the additional lifting table require the same maintenance as the
standard conveyor. Each conveyor belt must be maintained as described in the maintenance in-
structions. 11

11.4 Feeder position recognition
If the feeder modules are equipped with positioning fiducials, the fiducials can be measured.
If the "Conveyor position detection" function has been selected on the line computer, the function
will also appear in the Machine options. It can then be activated or deactivated at each station.

PLEASE NOTE 11
The "Feeder position recognition" function is always deactivated when the station is switched on.
If a track has been entered in the cluster data, the PCB camera on the feeder module will ap-
proach the position of the centering fiducial. Any centering fiducial offset determined during the
measurement will then be assigned to this track and added to the pick-up position during the pick-
up operation. 11

11.5 PCB data transfer
11.5.1 Functional description
The ’Machine options’ menu contains a ’PCB data transfer’ option. The aim of this function is to
increase the placement system’s performance on the line. To do this, an entire PCB is measured
at the
first
placement station and the associated fiducial, single circuit, ink spot, etc. data is deter-
mined, saved and sent to the next station. At subsequent stations, the data is then determined for
two fiducial positions only. These two fiducial positions are then used to correct the position for the
PCB to be processed at each station. It is thus not necessary to measure the entire PCB again,
together with its single circuits, ink spots etc. 11
