Claim 12:
13. The industrial automation controller as set forth in claim 12, further comprising:
a fan interface printed circuit board assembly connected to said housing and comprising a plurality of primary electrical contacts, said fan interface printed circuit board assembly operably connected to said processor;
a plurality of fan module contacts connected to said first fan module;
wherein said primary contacts respectively electrically mate with and engage said fan module contacts when said first fan module is located in its operative installed position for electrically connecting the first fan module to the fan interface printed circuit board; and,
wherein at least one of the primary contacts and its respective mating fan module contact is configured as a make-last/break-first contact pair such that upon movement of said first fan module from its operative installed position to its intermediate position relative to said housing, said make-last/break-first contact pair is electrically disconnected while other fan module contacts remain electrically connected to their respective mating primary contacts such that disconnection of said make-last/break-first contact pair provides input to said processor that said first fan module has been moved from its operative installed position to its intermediate position.
