1) For UL applications: only for use in "Class 2" circuits according to NEC.
2) Function:
The push-pull switching outputs must not be connected in parallel
3) Setting the Teach IN input disables the TEACH IN button (see page 10)
4) Only applies for automatic calibration during sheet movement (automatic teach)
5) 1=transient protection, 2=polarity reversal protection, 3=short circuit protection
6) These proximity switches shall be used with UL Listed Cable assemblies rated 30V,
0.5A min, in the field installation, or equivalent (categories: CYJV/CYJV7 or PVVA/PVVA7)
