5.3.6 Synchronous conveyor mode
5.3.6.1 Description
In synchronous mode, two PCBs of the same size are moved into the placement position
together. These PCBs must be processed as a common cluster.
This enables the topside and underside of a PCB to be processed on the same line. As a result,
it takes less time to transport the PCBs since two PCBs are always moved at the same time.
5.3.6.2 Function
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 cluster via two subpanels. (See
the user manual for the line computer).
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”.
5.3.6.3 Restrictions
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 ink spot’ option
cannot be used.
5.3.7 Controlling the dual conveyor using the Single Functions menu
The online help contains information on controlling the dual conveyor and on the Single Functions
menu.
5.3.8 Automatic width adjustment on the dual conveyor
The desired conveyor width relates to both conveyors. When the command is received, the con-
veyors are set to the desired width one after another.
PLEASE NOTE 5
Automatic width adjustment is deactivated if “synchronous transport” is selected.

5.3.10 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. 5

5.4 PCB barcode
5.4.1 Overview
The PCB barcode reader is used to automatically record and decode barcodes on PCBs. The
PCB barcode reader sends the read data via its serial interface to the machine controller for fur-
ther processing. 5
The PCB barcode readers are installed on the input side of the placement machine, above and
below the PCB conveyor, so that barcode labels on the topside and underside of the PCBs can
be read.
One or two PCB barcode readers may be retrofitted in order to read the topside and underside of
the PCB on the transport track. 5
