Page 5: Safety
Safety Safety VSI controllers are intended for assembly in switch cabinets and control Intended use cabinets. VSI sensors are intended for installation in vibration systems. VSI are used to measure the acceleration and dominant frequency of me- chanical vibrations by means of an acceleration sensor. Possible applications are the measurement of the operational parameters of vibration systems, e. - Page 6 Safety Safety DANGER rules Electric shock An electric shock will result in serious injury or even death. The VSI must be free of voltage during assembly, start-up, maintenance and troubleshooting. Observe the following five safety rules: 1. Disconnect the VSI from the mains supply. 2.

- Page 11 Design and function Root Mean A further important parameter is the Root Mean Square (RMS) or effective Square value. The RMS value of a time-dependent parameter a (t) in a time inter- val T is defined as the root of the sum of the squared measured values which has been divided by the time interval before: In case of a harmonic vibration the RMS is about 71% of the amplitude (exactly...
