6.14 Light barriers and stopper for scanning the PCB
positions along the transport routes
6.14.1 Function
The positions of the PCBs are scanned with the help of light barriers (transmitter and receiver
modules). The light barriers are installed above the conveyor belt and feel along the length of the
conveyor belt.
The light barrier signal stops the PCBs on the input conveyor, intermediate conveyor (HS-60 only)
and output conveyors. The light barrier in the placement area can be moved 50 mm against the
direction of transport to guarantee secure positioning of the PCB.
In the placement area the light barrier triggers the braking procedure via a DC motor. The soft-
ware regulates a constant time interval for the slow travel towards the laser light barrier.

6.14.2.2 Important instructions for replacing the light barrier
– The transmitter is installed on the fixed side of standard conveyor models, while the receiver
is on the moveable side.
– Check whether it would be helpful to feed in the new cable with the aid of the old one, as least
in some areas.
– The connection plug is equipped with contacts, which are pressed onto the wires. You may find
it helpful to remove the contacts from the connection plug, in order to run the cable better
through openings.
– For replacement purposes, the connection cable must be woven out as far as the relevant con-
version board of the conveyor side. This may be somewhat complicated depending on the rout-
ing of cables inside the machine base.
