The limit switches must be readjusted when they are not active in the respective position
of the slide (not lit up).
If the limit switches are not active, no notification about the end position of the slide is
issued to the controls and the system stops.
To adjust this, the compressed air remains switched off and the mains switch of the
device is switched on for power supply.
Push the feed slide into the end position of the limit switch to be adjusted. Then, move
the limit switch until its LED lights up.
