Parameters:

Currently, only the integrated search run is rejected with this alarm. The integrated search run is activated, if search run is triggered in the Stop program state. In other words: Parts of a program have already been executed and a following program part is “skipped” with search run in order to continue the program afterwards.
Reactions:
– Alarm display.
Remedy:
Repeat the action after the approach motion of the search run.
