Internal Switch Settings
The internal switches of the Model 682C05 must be configured for the Full Scale Output of the ICP
connected to it. This is accomplished by removing the front cover and sliding the PC Board out of the Signal
Conditioner. Once removed, the switches should be configured per one of the conditions in the following table.
Bearing Fault Detector: Set S1 for 1kHz or 5kHz (based on running speed). Range is fixed at 50g's Peak.
Overall Vibration:
Recommended Alert and Alarm Settings for Fault Detector:
Although each machine will have alert and alarm settings at various levels based on its high frequency spectra,
data has been provided as a baseline to approximate what these limits should be. Note that this data is a
recommendation and levels should be adjusted according to measurements taken from a detailed vibration
analysis and/or machine history. Please contact IMI Sensors for additional information and support regarding Alert
and Alarm settings.
