There are two conveyor modes: "Dual conveyor synchronous" and "Dual conveyor asynchronous.
Enter the conveyor mode you wish to use in the machine data (konfig.ma). 11
11.3.3 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. 11.3 - 1). 11
11.3.4 Changing the conveyor mode
11.3.5 Asynchronous conveyor mode
11.3.5.1 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. 11
11.3.6 Function
Once the machine has received the job data (cluster, set-up), the PCBs on the feeding belts are
continuously transported to the available center conveyor (provided that the center conveyor is
free) throughout the placement operation. The placement sequence starts as soon as a PCB has
moved onto the center conveyor. The PCBs are processed one after another. 11
PLEASE NOTE 11
The components to be placed and the width of the PCBs must be identical on transport track 1
and 2. 11
If the placement sequence is interrupted, the conveyor interface will be disabled and the PCBs
currently on the center conveyor will be completed. 11
The conveyor interface is disabled or enabled simultaneously for both transport tracks. 11

11.3.7 Synchronous conveyor mode
11.3.7.1 Description
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 single cluster. 11
This enables the top and bottom of a PCB to be processed on a single line. This reduces the time
needed to transport the PCBs, since two PCBs are always transported at the same time. 11
11.3.7.2 Function
PCBs on transport tracks 1 and 2 are moved synchronously (i.e. the conveyor belts are indepen-
dent of one another, but are controlled synchronously) on the conveyor sections. The components
to be placed for transport track 1 and 2 must be organized as a cluster in two circuit images (see
the line computer operating instructions). 11
If only one transport track (or center conveyor) is occupied at the start of the placement sequence,
the circuit image for this conveyor section is identified as "do not place". 11
11.3.8 Controlling the dual conveyor with the Single functions menu
Control of the dual conveyor and the Single functions menu are described in section 5 of this user
manual. 11
11.3.8.1 Automatic width adjustment on the dual conveyor
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.
Automatic width adjustment is deactivated when "synchronous conveyor" is selected. 11

11.3.10 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. 11
