The transport type can be set to either “synchronous dual conveyor” or “asynchronous dual con-
veyor”. To do this, enter the transport type in the machine data (CONFIG.MA). 11
11.3.3 Definition of the transport tracks
The right-hand transport track (viewed in the transport direction) is designated “transport 1”, and
the left-hand track as “transport 2” (see Fig. 11.3 - 1
). 11
11.3.4 Changing the transport type
11.3.5 Asynchronous transport type
11.3.6 Description
In asynchronous mode, one PCB is processed on one transport track, while another PCB on the
second transport track is moved into the placement position. This saves the full transport time,
greatly increasing output, particularly for PCBs with a short cycle time. 11
11.3.7 Function
If the machine is supplied with job data (cluster, set-up), at any given time during placement the
PCBs on the input conveyors are transported onto the center conveyor (if it is free). The placement
sequence starts as soon as a PCB has been transported onto the center conveyor concerned. The
PCBs are processed one after another. 11
PLEASE NOTE 11
The components to be placed, and the width of the PCBs on transport tracks 1 and 2 must be iden-
tical. 11
If the placement sequence is interrupted, the transport interface will be disabled, and the PCBs
currently on the center conveyors will be completed. 11
The transport interface is enabled or disabled for both transport tracks at the same time. 11

11.3.8 Synchronous transport type
11.3.8.1 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. 11
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. 11
11.3.8.2 Function
PCBs on transport tracks 1 and 2 are moved synchronously onto the transport sections (i.e. the
conveyors are controlled synchronously, but independently of one another). The components to
be placed for transport tracks 1 and 2 must be organized into a cluster via two subpanels. (See
the user manual for the line computer). 11
If only one transport track (or center conveyor) is full when the placement sequence starts, the
subpanel on this section will be identified as “not for placement”. 11
11.3.9 Controlling the dual conveyor using the Single Functions menu
Control of the dual conveyor and the Single Functions menu are described in chapter 4 of this user
manual. 11
11.3.9.1 Automatic width adjustment on the dual conveyor
PLEASE NOTE 11
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.
Automatic width adjustment is deactivated if “synchronous transport” is selected. 11

11.3.10 Technical data for the dual conveyor
11.3.11 Maintenance
Maintenance for the individual conveyors and the additional lifting table is exactly the same as for
the standard conveyor. Each conveyor belt must be maintained as described in the maintenance
instructions. 11
