The VS2 and VS2C are designed for use in non-hazardous loca-
tions. They have leaf type SPDT, double make contacts that can
be used for shutdown and/or alarm. They have a slotted sensitivity
adjustment located on the side of the case (see drawing below).
Model VS2EX is housed in an explosion-proof enclosure with
threaded cover. This enclosure is CSA and UL listed for Class I,
Division 1, Groups C & D hazardous locations. In place of the
leaf type contacts, 2-SPDT snap-switches are used in this model.
Sensitivity is externally adjustable and, when tripped, the VS2EX
gives a TATTLTALE
®
indication on the reset button. It is con-
structed to meet NEMA 7 specifications.
