Ready For Welding; Sticking; Error Signals; Process Active - EWM RINTX12 STANDARD Operating Instructions Manual

Design and function
Process signals

5.10.2 Ready for welding

This signal indicates general readiness for welding and should be checked before starting.
The following conditions will inactivate the signal:
− Process running, "Ready for welding" is activated again after the process and gas post-flow time have
been completed
− During JOB switching (duration approx. 200 ms).
− As long as an error persists
− When switching on thy system after initialisation, the signal is activated.
Signals activated
X7/6 to X7/4
X7/6 to X7/5

5.10.3 Sticking

The signal displays any sticking of the welding wire onto the workpiece via the internal detection system.
This signal should be evaluated using a positioning device towards the end of the welding process. Any
sticking detected is displayed until either a new process is started or the wire is cut free from the work-
piece.

This device can only be used with welding machines with integrated sensor voltage!

5.10.4 Error signals

This sends system error messages to the cascade control. Errors are signalled only as collective errors;
details on the error must be read off the system via a control unit.
No re-start is possible for the duration of a system error.

5.10.5 Process active

The signal is active for the duration of the entire process, starting with the gas pre-flows to the completion
of the gas post-flows after the process. The positioning device can be used as a condition of movement.

5.10.6 Main current signal

When the main welding program starts, this signal is set and reset after that program is exited. It is used
by positioning equipment as an additional trigger signal when using the current start and end programs in
the non-latched special operating mode. These are normally used for pre-heating or for treating the end
of the seam.
