throughout the placement operation. The placement sequence starts as soon as a PCB has
moved onto the processing belt. The PCBs are processed one after another.
If the placement sequence is interrupted, the conveyor interface will be disabled and the PCBs
currently on the processing belts will be completed.
The conveyor interface is disabled or enabled simultaneously for both transport tracks.

3.7.3.7 Synchronous transport mode
Description 3
In synchronous mode, two PCBs of the same size are moved into the placement position at the
same time. They must be processed as a common panel.
In this way, the top and bottom of a PCB can be processed on a single line, and the time required
to transport the PCB is shorter since two PCBs are always transported at the same time. It also
ensures better utilization of the nozzle configuration.

PCBs on conveyor tracks 1 and 2 are moved synchronously onto the conveyor sections (i.e. the
conveyors are controlled synchronously, but independently of one another). The components to
be placed on conveyor tracks 1 and 2 must be organized into a panel via two subpanels. (See the
SIPLACE Pro user manual).
If only one conveyor track (or center conveyor) is full when the placement sequence starts, the
subpanel on this section will be identified as “not for placement”.
Restrictions 3
If the dual conveyor is operated in synchronous mode, the ‘PCB whispering down the line’ option
is deactivated. PCB barcode operation is not supported in this mode. The "Global bad fiducial"
option cannot be used.
3.7.4 Controlling and width adjustment
3.7.4.1 Controlling the PCB conveyor system using the single functions menu
The online help contains information on controlling the PCB conveyor system and on the single
functions menu.
3.7.4.2 Automatic width adjustment
When the command is received, the conveyors are set to the desired width one after another. Dif-
ferent widths are possible.
