FW MURPHY has made efforts to ensure the reliability of the Electronic Vibration Switch (EVS)
and to recommend safe usage practices in system applications. Please note that in any
application, operations and device failures can occur. These failures may result in full control
outputs or other outputs which may cause damage to or unsafe conditions in the equipment or
process connected to the EVS.
Good engineering practices, electrical codes, and insurance regulations require that you use
independent external protective devices to prevent potentially dangerous or unsafe conditions.
Assume that the Murphy EVS system can fail with outputs full on, outputs full off, or that other
unexpected conditions can occur.
