<Weld/No weld external>

PSI 6XXX.350 L1
This signal allows to disable the firing of the weld timer, which may be required for set-up
operations, e.g. ([Sequence] without current).
Apart from the <Weld/No weld external> signal, firing may be controlled by the setting of
Weld/No weld internal relating to all programs and a Weld/No weld setting relating to a
specific program.
These three firing settings are linked by "AND".
With firing deactivated, the [Sequence] of the started program in terms of its timing is the
same as with firing activated. However, no welding operation is performed because there
is no weld current.
-
<Weld/No weld external> :
0 signal ⇒ external firing switched ON via I/O interface.
-
<Weld/No weld external> :
1 signal ⇒ external firing switched OFF via I/O interface.
