I/O signals - SWI (Spot Welding, Interface)
On the I/O board DSQC 223 some input and output signals are used for the SWI function, see
the figure below. All inputs, however, are still freely programmable and within reach under
the MANUAL button. The outputs are also programmable as usual but it is not possible to
control them under the MANUAL button.
The GRIP 1 and GRIP 2 signals are used to control both the working stroke and the opening
stroke of the first gun . These signals have therefore also been put on the same board as all the
other SWI signals. GRIP 1 and GRIP 2 are also available if you have an I/O system.
If a double gun is used, GRIP 3 and GRIP 4 are used for the working stroke and, opening
stroke, respectively, of gun two. These output signals are then defined in the usual way in the
functional parameters.
An example of reserved inputs and outputs for the SWI function, if the board is placed in the
second space.

NOTE 1. If flexible I/O (I/O-MAP) are used, are SWI-input every time 1 - 6 and SWI-output
1 -13 see table independence of wher SWI-board is defin. This in- and output must be defined
in I/O MAP.
Note 2. Reserved input signals that are not used must be strapped to 24 V. This does not apply
to WELD READY, which has to be supplied from the welding controller (see above) to make it
possible to execute the SWI -instruction.
