• Connection of two separate SN proximity switches of Category 3/S:
Since a short-circuit between the proximity switch circuits cannot
always be detected, they should not be connected by a common multi
wire cable, unless a cross-circuit between the two proximity switch
inputs can be excluded by protected wire laying or similar means.
The following function devices can be used in this application while
operating the AS-Interface safety slave together with a safety monitor of
types VAS-1A-K12-U or VAS-2A-K12-U to meet the requirements of
Category 3:
