UPPER LIMIT SWITCH
The optional Upper Limit Switch is used as a safety interlock in automation to
prevent the movement of material handling equipment (indexing) when the
horn is down. It also initiates the movement of material handling equipment
when the horn is up.
The Upper Limit Switch is factory set and should be suitable for all
applications. If for some reason you need to readjust it, observe the following
procedure:
1. Maintain air pressure and unplug the power supply from the electrical
source.
2. Remove the four screws holding the five-sided cover.
3. Loosen the jam nut holding the 8-32 cap screw in place.
4. Rotate the cap screw counter-clockwise (down) until the Upper Limit
Switch closes.
5. Tighten the jam nut to lock cap screw in position.
6. Replace the cover and four screws.
The Upper Limit Switch is now set.
