5.3.2 General
As the name suggests, the dual conveyor has two transport tracks, which are electrically and me-
chanically independent of one another. In the Standard version, the right-hand side is the fixed
side. There is another version, however, in which the left-hand side is the fixed side.
5.3.3 Defining the transport tracks
The right transport track (viewed in the transport direction) is designated "Transport 1" and the left
as "Transport 2" (see Fig. 5.3 - 1
).
5.3.4 Asynchronous conveyor mode
5.3.4.1 Description
In asynchronous mode, only one PCB in a transport track is processed. At the same time, another
PCB in the second transport track is moved into the placement position. This saves the full con-
veying time of one PCB, thus considerably increasing performance, particularly for PCBs with a
short cycle time.
5.3.4.2 Function
Once the machine has received the job data (cluster, set-up), the PCBs on the feeding belts are
continuously transported to the available processing belt (provided that the belt is free) throughout
the placement operation. The placement sequence starts as soon as a PCB has moved onto the
relevant 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.
5.3.5 Controlling the dual conveyor with the Single functions menu
Control of the dual conveyor and the Single functions menu are described in the manual ’Getting
started’.

5.3.6 Automatic width adjustment on the dual conveyor
PLEASE NOTE 5
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.

5.3.8 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.

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.
Fig. 5.4 - 1 PCB barcode block diagram
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.
A maximum of four PCB barcode readers may be retrofitted in order to read the topside and un-
derside of the PCB on the transport track.
