Vibration Switches The Smart Vibration Switch is fully user programmable using eitherthe Model 600A15 or 600A16 USB Switch Programmer Kit (optional). See the "Specifications and Ordering Information" on page 5 for details. These kits can be used in conjunction with any PC to read or reprogram the settings of the Smart Vibration Switch. The user can enable/disable and set the following switch parameters. Alarm threshold level & hysteresis Power-on, startup, & operating delays Normally open or normally closed Residual vibration leve ALARM THRESHOLD PELAY CONTACT To*Uyis \Yediies(Uy, AJJITIOI....

Vibration Switches Basic Installation Installation for Use with an External Relay This is a typical installation for use with a pilot/indicator light (or other load) where the current is ≤500 mA. No reset switch is required since the Smart Vibration Switch is set to NL (Non-Latching). This is a typical installation for use with an external SPDT or DPDT relay (see page 8 for relay selections). This configuration is used when the load requires >500 mA or when using a DPDT relay to switch two circuits using a single Smart Vibration Switch. The switching can be normally open, normally closed,...

Vibration Switches What is a vibration switch? A vibration switch is a device that (1) recognizes the amplitude of the vibration to which it is exposed and (2) provides some sort of response when this amplitude exceeds a predetermined threshold value. The switch response is typically an electrical contact closure or contact opening. The electrical contact may be either an electromechanical relay or solid-state triac. Vibration switches are primarily used for protecting critical machinery from costly destructive failure by initiating an alarm or shutdown when excessive vibration of the...

Vibration Switches About Mechanical Vibration Switches Mechanical Vibration Switches I For machines requiring simplified contact closure protection, Models 685A07 and 685A08 offer a cost-effective approach to vibration protection. They offer the smallest mechanical switch footprint available in either NEMA 4 or explosion proof housings. The three axis protection allows confident, reliable monitoring of small plant equipment in less critical situations, where the precision of an electronic switch isn't necessarily required. Both the weatherproof and explosion proof versions contain manual...
