Installation
The VS2 and VS94 series shock switches are sensitive to shock and vibration in all three
planes of motion – up/down, front/back and side/side. Front/back is the most sensitive (the
reset push button is located on the front of the unit). For maximum sensitivity, mount the unit
so that the front faces into the direction of machine rotation. (See Dimensions for sensitivity
adjustment location).
The VS2 and VS94 Series must be firmly attached/mounted to the machine so that all
mounting surfaces are in rigid contact with the mounting service of the machine. For best
results, mount the instrument in-line with the direction of rotating shafts and/or near bearings.
In other words, the Reset push button should be mounted pointing out, perpendicular to the
axis of rotation (see Typical Mounting Locations). It might be necessary to provide a
mounting plate or bracket to attach the VS2 or VS94 Series to the machine. The mounting
bracket should be thick enough to prevent induced acceleration/vibration upon the VS2 or
VS94 Series. Typically ½ in. (13mm) thick plate is sufficient. See illustrations in Typical
Mounting Locations.
CAUTION: A dust boot is provided on the Reset push button for all
series to prevent moisture or dust intrusion. The sensitivity
adjustment for model VS2EX is not sealed; therefore, mounting
orientation should be on a horizontal plane or with the sensitivity
adjustment pointing down. Never point pressure washer wand
directly at the sensitivity adjustment screw. Doing so will cause
water intrusion resulting in internal corrosion issues. Sensitivity
adjustment for model VS2 is covered by a plug. The plug must be
in place and tight to prevent moisture or dust intrusion.
C-Clamp Installation (VS2C model only)
A C-Clamp is supplied with the VS2C model only. The C-Clamp is
shipped installed on the VS2C but may optionally be installed on the
VS2EX and VS2EXR switches.
1. The C-Clamp (B) will already be installed on a ¼ in. (6mm) thick
steel mounting plate. (A). Bolt the VS2EX and/or VS2EXR
switch to the mounting plate as illustrated – with four 5/16 in
bolts, nuts and washers.
2. The mounting location should provide convenient access to the
