13.2 Interface ( 2 )
Interface circuit board, View of soldering side, as installed
46
The interface consists of a circuit board which conducts the electrical
distribution and at the same time contains electrical adaptions and
interlocks.
Measurement Points
Via the the distributor the various controls are interconnected and their
signals sent "mixed" to the individual components. The assignments in
the plug connectors allow for the use of this interface with similar
machine distributions.
The electronics are designed to be equally multifaceted. For example,
a cl. 219 with additional width controls can be attached because the
required timing alterations for bartacking and MW signals are already
been built in.
For the cl. 550-12-12 described here only a small part of these
electronics are used.
The switching-over of the functions is made with small "hook" switches
on the circuit board.
Because further applications for these controls have not yet been
realised, only switch positions for cl. 550-12-12 were able to be
established.
