5.10.10 Output of analogue values

For the output of welding voltage and welding current, the RINT X12 has two analogue outputs as follows:
Output Parameter
X11/1 Welding voltage
X11/3 Welding current
The analogue output signals are updated with an average time constant of approx. 40 ms and are
only used for display purposes. For faster signal processing, the signals of the interface for
mechanised welding can be used!
5.11 Special functions
Several special functions of the RINT X12 are described below, some of which are available as software
options.

5.11.1 Position search

This function is implemented as standard in the RINT X12, and makes it possible to locate the workpiece
by means of sensor voltage. The function is activated by the X10/8 control signal and it then allows con-
tact with the workpiece to be detected by means of the K7 relay.
With MAG systems, the workpiece is usually located by means of the wire electrode or the gas nozzle
(please consider that the welding equipment must be specially prepared for the latter function).
Position searching can only take place outside the process.

5.11.2 TANDEM operation

This function is available as a software option and, in Phoenix / alpha Q systems, permits the control of
one power source in each case (for TANDEM systems, 2 RINT X12 are required). The X5/7 input signal
is used to determine which power source is subordinate in the TANDEM combination.

Signal active
Signal not active
TANDEM operation is described in the operating manual for the TANDEM power source.

5.11.3 WF switching

This function is available as a software option and enables 2 wire feed systems in Phoenix / alpha Q and
Tetrix / forceTig to be operated alternately.
With the X4/7 signal, you can switch from one drive to the other in the system. This function can only be
activated outside the process.
WF switching is described in the supplementary sheets entitled "OW DV SWITCH" (099-OW0963-
EWM00).
