Safety 1.1 Definition of Warnings DANGER! Hint for possible dangerous situation. Ignoring the security terms may cause death or serious injury. WARNING! Hint for possible dangerous situation. Ignoring the security terms may cause injury. CAUTION! Hint for possible damage of property, if the corresponding protec- tive measure were disregarded. - Page 5 DANGER! Risk of Injury by Movable Parts While normal operation, as well as inadvertent loosening of parts of the telemetry system during operation, present persons may be injured if protective equipment is absent. Check the safety function of the protective equipment particularly –...

Page 6: Conventional Usage
Conventional Usage Sensor telemetry systems are used for contact-free data and power transfer from passive and active sensors (e.g. on rotating shafts). DANGER! Risk of Subsequent Damages caused by Malfunctions If the telemetry system is used for controlling or regulating func- tions it is not conceive for, subsequent damages up to injury to persons can be caused. -
