8.1 Installation of proximity switches
To avoid faulty switching and external influences, observe the minimum distances

Slots for proximity switches
1.
Position the proximity switches in the slots [1].
Use the lower slot for the DGSL-...-4 and DGSL-...-8 products.
2. Temporarily lock the proximity switch.
3.
After the test run, mount the proximity switch in the suitable position.
8.2 Rough setting of end positions
1.
Position the slide at the desired end position by hand. Leave the slide in the
retracted end position during the setting procedure.
2. Unscrew the retaining screws of the (fixed) stop
1 and the orifice 2.
– Certain product variants allow coarse adjustment of the front-end position
