Power, Transformer and Temperature Contact

For detailed information on the electric connection of a single unit,
.
please refer to the
D "Control and I/O Level, Technical Information" documentation
of the particular unit types (PSx 6xxx.100, PSx 6xxx.190 and PSx
6xxx.000) and
D in the manual of the power section used (see page 1-1).
The present manual provides supplements to this information that
is essential for using the master-slave mode.
It is not necessary to turn on the master and the connected slaves simul-
taneously (logic supply at X4).
It should, however, be noted that the master signals "Ready" to the hig-
her-order control logic only if all connected slaves signal "Ready" to the
master (logic/power supply present, connections to the master establis-
hed, etc.).
Ensure that all connection lines are appropriately dimensioned!
L
Ensure that the stop circuit is interrupted even in case of a slave failure!
L
Only welding transformers with identical electric data may be connected
L
in parallel.
Only use connection lines of the same length for all parallel transformers
L
in the primary circuit.
Only use connection lines of the same length for all parallel transformers
L
in the secondary circuit. If possible, connect the individual current bran-
ches in parallel shortly before the electrodes.
Connect the temperature contacts of all transformers used in series and
L
connect the complete circuit always to the master (X3, terminals 4 and
5).
The remperature input of a unit that is configured as a slave is deactiva-
ted automatically!!
