Description

The VS2 Series switches are shock sensitive mechanisms for shutdown of engine or elec- tric motor powered equipment. These switches use a magnetic latch to ensure reli- able operation. Explosion-proof “EX” mod- els for hazardous locations are available.

Applications

Ideal for use on engines, pumps, compres- sors, heat exchangers and pumping units, the VS2 Series can be used anywhere shutdown protection from damaging shock/vibration is desired. Switches are field adjustable to sen- sitivity required in each application.

Specifications

VS2 and VS2C

Case: Equal to NEMA 3R. Suitable for non-hazardous areas.

VS2: Base mount

VS2C: C-clamp mount, includes 45 ft. (13.7 m) 2-conductor cable, and 5 cable clamps.

Contacts: SPDT-double make leaf contacts, 5A @ 480 VAC.

VS2EX

Case: Base mount, explosion-proof aluminum alloy housing; meets NEMA 7/IP50 specifi- cations; Class I, Division 1, Groups C & D; UL and CSA listed*.

Snap-switches:2-SPDT snap-switches; 5A

@480 VAC;* 2A resistive, 1A inductive, up to 30 VDC.

Normal Operating Temperature: -40 to 140°F (-40 to 60°C).

VS2EXR

Case: Same as VS2EX.

Snap-switch:1-SPDT snap-switch and reset coil; 5A @ 480 VAC;*2A resistive, 1A inductive, up to 30 VDC.

Remote Reset : 115 VAC or 24 VDC (specify).

VS2EXRB

Case: Explosion-proof aluminum alloy housing; rated Class I, Division 1, Group B hazardous areas.

Snap-switch:1-SPDT snap-switch with reset coil (option available for 2-SPDT switches); 5A @ 480 VAC; 2A resistive, 1A inductive, up to 30 VDC.

Remote Reset: 115 VAC or 24 VDC (specify).

Basic Operation

Pushing the reset button moves the tripping latch into a magnetically held position.

A shock/vibration will move the magnet beyond this holding position, thus freeing the spring loaded tripping latch to transfer the contacts and shutdown the machinery (see dimensional diagrams in the following pages for visual representation of parts).

Remote Reset Option (VS2EXR and VS2EXRB)

The remote reset option includes a built- in electric solenoid which allows reset of tripped unit from a remote location.

Available for 115 VAC or 24 VDC.

Warranty
