Basic Wiring Question

(1/6) > >>

javeryh:
It's about that time... I've never done something like this ans I'm a little intimidated... anyway:

Each microswitch gets two wires running from it - one from NO (normally open) and the other from COM, right?  I know each wire from NO gets wired directly to the corresponding node on the iPAC but where do the COM wires go?  Can I wire one COM node to the next COM node to the next COM node and so on?  If so, what happens to that last wire?  Can I wire it to the first COM node creating a circle or does it go somewhere else?  Or am I way off base here?

Thanks.

rdagger:
The last com goes to the ground on your encoder.

javeryh:
Thanks.  So wiring one COM to the next creating a loop is an OK way to go about doing this?

JonnyBoy:
Yep, you can daisy chain the grounds together and shoot them right over to the ground terminal on your ipac.

ChadTower:
That is called a daisy chain ground loop.
