In the 6000 Software Reference Guide, when talking about a normally open/normally closed switch and setting the active level, the guide currently states that:
If a normally-open switch is used, the active level should be set to one(HOMLVL1--Active High).
If a normally-closed switch is used, the active level should be set to zero(HOMLVL0--Active Low).
If a sinking switch is used and AUX-P is pulled up to 5-24V (a typical configuration) then the user guide is incorrect. If a sourcing switch is used and AUX-P is connected to ground, then the user guide is correct.
Here is the bottom line:
If a sinking switch is used with AUX-P pulled up to 5-24V:
Normally-Open switch----use HOMLVL0
Normally Closed switch--use HOMLVL1
If a sourcing switch is used with AUX-P pulled to ground:
Normally-0pen switch----use HOMLVL1
Normally-Closed switch--use HOMLVL0
